Energy and Structure: Stress testing your physiology

This post stems from a question on Discord about why I’ve moved away from drinking milk (and if you haven’t joined my Discord server, please do, there are a lot of smart people on there with lots of different experiences).

This is going to be a bit all over.

Most of the benefits of milk are from the milkfat and some of the more exotic lipids contained in the milkfat.

The galactose is beneficial in certain contexts because over the long term if your cells have a diabetic like phenotype or a hypoxic phenotype (dare I say they are basically the same thing), galactose will shift the cell state to increase OXPHOS increasing ATP and oxygen consumption, glucose doesn’t seem to be able to shift the cell metabolic phenotype in a positive direction except to maintain whatever state the mitochondria are in and potentially worsen it if cells are in an already diabetic like phenotype and glucose isn’t being directed properly. Fructose definitely can in the right contexts.

Glucose is not a good metabolic substrate to rely on predominately if you are an organism that relies on palmitic acid driven OXPHOS and like to breathe oxygen; and I would distinguish between a basal and peripheral metabolism here. From my experiences you can have quite a bit of potatoes and still have room to breathe.

It’s important to note that acute exposure to galactose will not cause this shift, cells have to be exposed chronically (environmentally) for the shift to occur permanently. Once the steady state is restored cells will happily burn palmitic acid and a nice physiological insulin resistant state can be restored.

When I think about milk and in particular the galactose and ketones increasing at altitude it’s not hard to imagine that milk is the input which produces the desired metabolic output i.e. moving from a hypoxic to normoxic environment. Not too much different than fructose driven glycolysis in low oxygen environments.

When I think about ketones and their ability to “prevent” or “reduce” the consequences of hypoxia I think given how high they are in human babies that mitochondria are still developing oxidative capacity and the internal “atmospheric conditions” are being buffered if not facilitated by lactate.

Tissue unsaturation does increase as one climbs in altitude and this may account for the higher rates of skin cancer and so do ketones.

All energy substrates have “innate”, yikes, pros and cons that will make your life adaptive or miserable as internal and external environmental factors change. One prediction would be that as oxygen becomes less available there is more reliance on glucose as a suitable energy substrate along with raises in ketones and lactate. And in some cases fructose. When exogenous glucose is not available fat serves the ketone lunch.

This is why ketosis is not appropriate in my opinion except as an intervention. Ketosis is a side effect, the benefits come from SFAs.

And while the intervention can resolve symptoms, it does not as far as I can tell “cure” things, it just keeps life going but you still slowly fall apart.

To cure things, you have to provide stimulus that can rebuild structure. And so, this builds on my energy and structure post.

So why don’t we want to drink milk all the time if it has the benefits of restoring OXPHOS? Restoring is the key word here. Well when I drank milk all the time I found that my diet was quite limited and I’m a guy who likes variety and thinks monotherapy diets are interventions not cures and tend to think they predispose people to orthorexia and a host of other psychological problems.

Eventually you get tired of milk and want a bit of substance. I tend to pay attention to what I’m hungry for, I tend to trust that, maybe a bit too much for some people, maybe not enough, I’m cautious and there is some logic behind how I judge whether or not a craving is a real need verses something more psychological. That doesn’t mean you shouldn’t eat something for psychological reasons and there is definitely some interplay in which a psychological craving might have overall benefit. But let’s not get too spooky here.

When you get to the point where your like, I’d like to chew on something, it’s probably a good sign that you need to chew on something besides the meat in your meat and milk diet.

For those of you who understand my cryptologic you’ll know that I’m not a fan of fruits and vegetables, but I am a fan at the same time because I like a little NERF ball. That is Nuclear factor (erythroid-derived 2)-like 2 or NRF2.

I think, though this is working through some higher level signaling (not everyone can conceptualize the implications of metabolic substrates and NRF2 is a good place to have that dialog), that this is one of the ways antioxidants work, it’s not because they are functionally benefiting the system, it’s because they are assaulting the system and whittling out adaptation by increasing our own mammalian antioxidant system (this explains the dose bell curve of antioxidants as well), since exercise, antioxidants, and other stressors (psychological stress) hit NRF2 it is a good common ground and the proverbial point in which “cures” as differentiated from “interventions” happen or can happen.

Once OXPHOS is stable, how do you approach making it antifragile? You begin by coming off your monotherapy diet and stress testing it. Not much different than a baby. You start by gently exposing it to the environment. If you protect your baby too much it will be maladapted and if you stress it too much it will be maladapted. You want that sweet spot or zone of proximal development a psychological concept which originated with Lev Vygotsky which I think applies to physiology or is a good way to conceptualize physiology.

And that is the beginning to a long process. I started off with herbs and spices and a bit of starch. Even herbs and spices were a bit uncomfortable at first much like the first time you pick up a weight or attempt a long walk or a short jog. But it starts there. And for now, that’s were we’ll end.

Best wishes,

Problems of perspective in the nutritional ethos

I was born by cesarean section. My mother was in labor with me for over 36 hours before they decided to do the procedure. From the time I was born till the time I moved out of my parents’ house I was sick all the time. Right from the get go I had trouble breathing and was sick with pneumonia every 3-4 weeks. At first, they thought I might have cystic fibrosis and after ruling out other possible diseases and environmental factors they diagnosed me with severe chronic asthma. I missed a lot of school and spent those every 3-4 weeks in hospitals around the country hooked up to IVs and monitoring equipment, I grew up on steroid inhalers, breathing treatments, and antibiotics. On top of that because of my father’s culture, he believed that crying babies just want attention so from the very get go if I was to cry at night because I was hungry he would not let my mother feed me (or so the story goes) so I was starved during preweaning period of my life (whether it was my father’s or mother’s doing). Despite those things, I was always intensely curious about how things worked, by the time I was 2 I had already taken apart my first radio and put it back together, socially I was maladapted, and had to repeat kindergarten because I was too quiet, really I just was in the habit of keeping my mouth shut and very much liked to observe things intensely i.e. watch and learn.

Socialpsychologically the environment I grew up in was very stressful, my Dad was never easy on us, he never hit us, but he didn’t make life easy, if we had a question which I always did he’d be like go look it up in a book or some other informational resource, answers never came easy without due effort, and so from a very young age I was incredibly resourceful and knowledgeable, Dad would say don’t waste my time with your curiosity if it really means something to you figure it out because I’m busy providing a roof over your head and putting food on the table (to his credit he did initially show us and tell us where we could find answers). The health problems and the stressful environment went on till I graduated high school. Shortly after which I moved out of my parents out and went out on my own. After I did that most things in life became quite easy as long as I had interest in them and my health problems miraculously disappeared till I started fiddling with my diet. I guess you kind of learn what’s important after you almost suffocate a couple times and your O2 saturation goes to subhuman levels, and you learn to look on the bright side, to be happy with just being able to wake up in the morning and breathe, and I learned those things at a very young age, which allowed me to see through the bullshit parts of life and culture.

One of the things I learned in the military when I was considering cross training into psychology was working with PTSD patients in group therapy settings. PTSD patients all somehow see their tragedy or make their tragedy worse than the other person telling their story to one up the next person and try to invoke sympathy and attention, it usually isn’t as sinister as that (sometimes it is), but the interesting thing is that while there maybe be stories that are objectively worse than another person’s story, they all perceive their tragedy individually as worse than the next person’s, but the perspective pain/and physiological manifestations are real and it is just as worse as the next guy’s story in the pain the person feels. That is a real. The feelings are genuine. So you learn in treating people with PTSD that all pain is perspectively equivalent to other’s even though objectively seeing your friends shot is something a bit different than being shell shocked or having a substance abuse problem. What is different though is the objective tolerance a person has when exposed to future traumatic events. And you pay attention to that, because those are the ones who can cave for the most ridiculous reasons, though they are not ridiculous in that person’s mind, and turn around a shoot you just for being a little insensitive or cutting you off in traffic, etc.

There is a perspective problem in the nutritional world on various 1st world forums, it’s like, you know maybe you can’t tolerate certain foods, I looked at Polish Hunter’s Stew and am like man that looks fucking delicious, but that cabbage looks like it is going to rip a crater through my intestines and produce enough atomic gas to reach escape velocity and send me to the moon, but I’m not going to lose sleep over it because objectively there are people starving to death every day. I’m going to be happy with what I can eat, push the boundaries when I can and if the boundaries recede and make me fart, give me acne, or make me bloated, I’m going to be glad that that is all I have to concern myself with, is that I have a choice.

September 10, 2017 update

Good evening, ah, ah, ah, just finished having 2 cheeseburgers and coke and a craft ginger ale. It’s heavy squatting season again and experience has taught me that during that type of maximal training even a calorically restricted diet of cheeseburgers and coke is far superior to any amount of rice and lean meat I might be able to shove down my throat both taste wise and recovery wise. I prefer the Ivan Abadjiev diet while engaged in lifting.

Ivan is an interesting guy if you can get past the steroids, then again I think a fair percentage of the Ray Peat forum has dabbled in banned substances. He seemed to have a good grasp on physiology in a practical way and in my opinion a better understanding of stress than Peat as far as how Peat frames stress. In fact he has a view of stress much like my views.

It’s funny I was listening to a podcast with Ray Peat, and sometimes I get the distinct impression that if he is not a communist he at least is a sympathizer. Ideology has a funny way of setting up the framework through which you synthesize information.

I set up this blog more for myself than anyone else to track my own changes, changes in the way I researched topics and changes in my views, when you are writing in the present and with no money to make from it, you can look back, see where you have gone right and see where you have gone wrong. I like that. I like that I can change my mind about things and not feel bad about it.

I’ve come back to a way of eating that tries to avoid PUFA (not that that ever changed outside of some childhood favorites I craved every once and a while), but I don’t deemphasize carbohydrate as much as I used to, I’m quite liberal with them especially sucrose. I eat carbohydrate to taste and fats of the saturated sort to taste and protein to taste, it ends up being my macro ratios are pretty balanced between one another (and incidentally when they are the most palatable). I tend to like the idea of a little bit of physiological insulin resistance promoted by saturated fat so that glucose is shunted to hepatic glycogen and muscle glycogen stores.

I’ve changed my views on things like aspirin. The so called blood thinners and blood thinning effect I think we tend to think of that literally like thinning paint but when I factored in structured water my views changed.

I think carbohydrates are pretty damned individual as far as sucrose verses starch, there are certainly ways of preparing starch that seem to be more healthful but some people seem to tolerate starch regardless of the preparation.

Endotoxin has always been interesting to me, Vodka seems to work fine as a mouth wash and eternal internal cleanser, just don’t go overboard :) a cigarette can also modulate the vagus nerve as well, as for the hot gas, if your pulmonary alveoli are saturated not sure the gas is hot enough to raise the saturated lipids to their smoke point as for the tar and other stuff I’ll take my chances.

I’ve never been a fruit kind of guy, I tried the filtered OJ way back in the day and recently I found some high quality OJ that I tried for a while, you know because it is supposed to be better, I strongly disagree with the reasoning on that and I think there are good reasons to avoid it. I love craft soda and I think the lack of “nutrients” tends to guide cravings a little more accurately.

I drink milk on occasion but for the most part tend to favor cream.

Over the past few months I’ve experimented extensively with topical supplements. Pregnenolone, DHEA, Progesterone, T3, T3/T4, the fat soluable vitamins, etc. I will say that all of them seem to be much more effective topically. They are useful sometimes but can, for most, be a tripping point, if you aren’t approaching their use systemically.

Witches and stews

I had a good laugh the other day about ancestral eating because I was watching a fictional show on TV where they were preparing an old-fashioned meal—a stew of some sort—and then a few scenes later burning a witch at the stake. There was something cosmically hysterical about that to me.

I remember back in the early days of the ancestral eating movement how there was this kind of fairy tale idea that our ancestors where healthier than us.

The entire idea of “diseases of affluence” is on shaky ground as far as I’m concerned. It’s more so that diseases come and go and/or are “born” depending on numerous environmental and sociological factors and the “fitness” of a given population.

So said person doesn’t have diabetes and isn’t overweight but burns people. I’ll take the diabetic over the plantation owners.

Sanity should be considered.

The Ray Peat Forum is welcoming back banned members

For long time readers of this blog you will of course know that I was banned from the Ray Peat Forum in October of 2013. When I left the forum I basically started writing here and I guess I have achieved “legend” status as every now and then since then if I’m mentioned on the forum I will occasionally get emails from people saying as much. And when others have been banned I sometimes have gotten emails from them as well.

Today I received an email with the following quote:

If anyone has been banned and would like to come back and be a helpful, peaceful, loving member of this community. Reach out to me and let’s work things out.” ~Charlie

I documented my original banishment into exile here. I did enjoy my time contributing to the community, and I was “a helpful, peaceful, loving member” but I think a large part of me since then has blossomed into something more promising.

This quote just never set well with me:

“The forum was created specifically for people to come and discuss the work of Ray Peat – not to debate it, to discuss it, share insights about it and work together to understand it while gaining their health through the practical use of his information.” ~Charlie

I’m just not into manufacturing consent. I know a lot about manufacturing consent. It happens every day all around you and I do my best to avoid it. Although I don’t get to post a lot on here I do have loyal readers and people who send emails asking how I’m doing, post interesting comments that are sometimes funny, sometimes challenging to my own ideas, but always thoughtful.

There is something very sexy about truth even though she can be ugly sometimes. She isn’t always attractive, but she never lies.

And finally a quote from the good book (NIV):

“Do not give dogs what is sacred; do not throw your pearls to pigs. If you do, they may trample them under their feet, and turn and tear you to pieces.” ~Matthew 7:6

Best wishes.

Maybe our ancestors processed carbohydrate simply because they didn’t want a belly ache.

I’ve heard it said in some arguments that the activity of refining a carbohydrate in ancestral times e.g. wood pulp to make it edible (yes, that is a thing) or other plant-like crap was because when people are hungry that they are processing a said food for the sake of energy density or something like that. I’m probably remembering the exact explanation wrong.

To be fair there are some reasons why that might be true and there some reasons that perhaps raise more nuanced questions.

Nuanced questions can be exhausting depending on your disposition, how old you are, etc. Some folks settle on an idea, fully well knowing there is more to the story, but because the question is so exhausting to explore and there are so many interacting variables, the question is laid to rest and an assumption is made. And we are all guilty of that.

I largely find that behavior a symptom of aging or energy deficit. But some people will say well I don’t have time to think about such things, so I’m just going to continue on standing on that soapbox and promoting it as something good for the general public because it works for me. And I’m cool with that (the part where you do your own thing), except, then if you are going to be like that then you need to not be judgmental. Or if you are going to be judgmental which is your right, then STFU about it and tender some evidence.

Sometimes you see that in fanatical religious people, the world is changing around them, becoming more complicated, yet there is this disconnect and simple-minded resistance against recognizing that the world is changing around them and fossilizing their ideas. Which in the end means they are wrong and for those types is like hell-on-earth, but they’d probably admit that, which would lead to a conversation about heaven.

Now if I’m starving to death, I’m going to either be hunting for food or digging for food, then I’m going to light it on fire, cook it and eat it. Processing food can be very labor intensive. And in the case of processing wood pulp, can take 2-3 days before it’s finally edible. It also takes a group of people. A labor force of sorts. And so those folks are going to be expending a lot of energy and maybe they might need to eat more. So what would be the point of all that.

Maybe partly for security. Like job security except for food. Because maybe digging for der ders isn’t always a reliable source of food. You know how it is you go to your job you work, you might not like it that much or maybe you do, but you do it anyway because you know at the end of it, you’ll get your paycheck, and you’ll get your reliable source of food, your PS4, cable TV, and Internets. And according to some you’ll get obesity along with it. And that is a pretty sweet deal when you get to have this kind of guaranteed relaxation; even for diabetics. And because of that relaxation time some curious chap had the time to think about things and make some medicine that the diabetics could take to prolong their life for a while longer, even if in the end the medicine ends up killing them, it did allow them to prolong their habits for better or worse, got to die of something (lets not miss the overall point of that please).

Then you have these folks saying it is healthier and more evolutionary appropriate to go out sweat and look for food, expend energy, have irregular sleep patterns, maybe eat a poisonous root mistaken for a potato, or raped by a bear, etc., in a modern day context.

And maybe if that was the only thing you were doing you would be healthy and “happy” if you were lucky enough to avoid disaster. But that is like pulling the rat out of his cage that I mentioned in a previous post where you take a group who is in one context very healthy and drop them into another. Probably not going to have good results but who knows you might. There was a big experiment done called Paleo, and it’s still ongoing in various forms.

Because some people decided to promote this thing called Paleo. I’m talking about the low carbohydrate version which is probably on version 99 right now. And for some they say it worked and (in another post we are going to explore the term “worked” and what that entails) made their blood markers improve, made them loose weight, got them off medications, etc.

However, overall the general trend has moved back towards the argument of having carbohydrate despite those beneficial things (which tells me that at best restricting carbohydrate it is an effective intervention therapy for some that somewhat makes static, depending on how you look at it, or “reverses” in the sense of symptom relief, but not cures, a overall declining physiological state). First it was things like sweet der ders, der ders, rices, taro, etc., I think that started with Paul Jaminet and safe starches years back.

And now even though I don’t really pay attention anymore it seems like people have gravitated towards more of a whole foods type thing that seems pretty balanced. But the battle scars are there. I see a lot people who are now worse off. For example, a few months back someone posted a recent picture on Twitter where there were some notable Paleo folks sitting down around a table having steaks and salads. And the steaks I’ve got no problem with really, I have meat when I’m hungry for it. But they are were all balding to various degrees and they didn’t start that way. But hey, that way of eating is supposed to promote the image that fertile women are attracted to. Now they might talk about genetics and such and hey maybe people who are going to eventually be bald self-select for Paleo, but I don’t really buy into all that.

Just recently because I’ve been busy and under a rock I heard about this thing called Plant Paleo. I went into listening to the Podcast thinking this was going to be like a diet made mostly of starch and regular consumption of animal products just with the emphasis placed on carbohydrate. But it ended up being like not even a egg a day, low in animal protein, a lot of raw veggies, scheduled feasts, and a totally ridiculous bucket of horseshit. But it seemed to work for the guy, got him ripped and made him happy. That’s cool. I dig that. You are doing what works for you and gives the image for a male that is currently acceptable to our culture. I’m sorry but I prefer the softer looking appearance on males and females. If you are so ripped that I can see your internal organs it probably means you are useful for little else.

Like the first book I read close to a decade ago now was Weston Price’s, and for all it’s flaws the one thing I did not notice was the regular consumption of raw vegetables. But then there were other books I read like The Old Way and there too there was no impression that these folks were eating raw vegetables to maintain health.

And scheduled feasts, like that to me is just a reach around to again try to recreate some sort of fairy tale associated with good times and good health. I’m not into that and I feel it’s maladaptive and conducive to eating disorders.

I think the biggest lesson out of everything we learned about nutrition over the past decade is that industrial polyunsaturated fat should be avoided. Cholesterol is: who cares. And butter is good. And I say that being fully aware of some 90+ year olds and 100+ year olds had plenty of PUFA in their diet over their lifespan and where fine if we are ONLY considering longevity and not other factors that contribute to quality of life (such as sharpness of mind, mobility, etc.). And I have some interesting speculations as to why. And that same argument could be made against a lot of things to convince us that any risk when it comes to our diet is best avoided. But then that more often then not causes problems as well.

So the idea that carbohydrate was o.k. for our ancestors because they were looking for energy density and processed their carbohydrate for the sake of energy density makes little sense to me. Maybe they just wanted some pure ass, nutrient void carbohydrate, so that when they were out hunting the guy throwing the stone tip stick didn’t fall over because he got a cramp from all the fiber he ate and thus fail to bring home some food for his crew.

I often look at high level athletes for patterns and eating behaviors especially some of the differences between males and females, because I think performance, good performance dictates some important lessons (1) athletes often have some strange eating rituals, almost superstitious, instead of viewing this as some psychosomatic voodoo I’ve always taken the overall theme at face value and that athlete is eating what makes him feel well when he performs and when he is doing hard training which allows him to (a) perform, (b) recover and (c) wake up and do it again the next day because if (d) he can’t then he fails at whatever he is trying to accomplish. And I think we can extend some of those concepts to regular folks like you and me and apply them to life.

The whole paradigm of Paleo, or LCHF, started as a good thing not because it is the ultimate truth, but because it caused us to pause and reflect and look at things more carefully much the same way that for some Dr. Peat was and is an inspiration. But Dr. Peat went a step beyond and inspired some to go down a road that was less traveled and inspire meaningful thought and curiosity which in the end I believe is more health giving and enriching then rigid guidelines and inflexible eating frameworks and in reality just another case of herd mentality. Dr. Peat’s contributions are not about sugar and PUFA his main contribution in my opinion is having some balls. He demonstrates his ability to evolve with the ever changing scientific literature all while maintaining an overall consistency. That’s a beautiful thing. Having a big pair of balls i.e. the ability to think for yourself is increasingly important (not that it ever wasn’t). Being consistent does not mean you are biased. Being biased usually means you are inconsistent. 

Where Paleo and LCHF fails now in my opinion, and for a long time now, is that they are becoming exactly what they criticized rushing to conclusions too quickly. And then you have those bundles of sticks that are o.k. with sugar taxes, WTF. Like seriously, WTF. Why don’t you first figure how to make food affordable before you start imposing more taxes, that go to who exactly?, healthcare costs?, sounds like wishful thinking to me. What a bunch of tools. How such a “free thinking” and “critical” crowd can think more authoritarianism is conducive to better health because we are too stupid to know better is somehow the solution to ANY problem is beyond my simple mind. Why don’t we just allow people free access to published research show students how to access it preferably before college and teach them basic science and math and statistics so they can read it informed and let them and future generations draw their own conclusions.

I often get emails from people who are sick and they ask for advice. I usually respond with more questions or I engage the person in a way that offers support to their situation rather than answers. Because I don’t have the answers, I’m just a dude with a blog, anybody can do this, I just think in a way about things that sometimes makes people feel free to ask questions, there are lots of people out there like that. I’m not a Doctor, please stop sending me lists of symptoms and asking “What should I do?”. I think unless you are dying or have a GSW to the chest, that the helplessness and hopelessness that you feel is because you are looking for answers, stop looking for answers, look to ask the right questions and then SEEK the answer, that order is important.

Maybe our ancestors processed carbohydrate simply because they didn’t want a belly ache.

Maybe it’s a mixture of both energy density and not wanting a belly ache and security. But for sure it’s not simply energy density because I’m starving.

Below the butter: bread

Note: More pictures to come!

This weekend Elyse and I took a trip up to Massachusetts to visit the Berkshire Mountain Bakery featured in Michael Pollan‘s Cooked documentary.

Bread has always been an interesting topic for me and there is a past post where I talked about bread and butter and the idea that around the time we started removing the butter from our fridges and counters we started seeing more gluten intolerance.

When I was a kid I would pilfer butter and bread in the moonlight while everyone was sleeping. Bare chested I would take a plain slice of Wonder bread, spread a thick layer of butter on it, fold it in half and smash it together, and eat it.

[A superior butter transport is in fact raisin bread which allows 2 sometimes 3 layers of butter before caving in under structural stress. I studied this. The raisins act as miniature tension rods.]

Sometime in my 20’s I did this diet where I eliminated bread from my diet. I read things about gluten, gliadin, schizophrenia, gluten ataxia, various autoimmune disorders, etc., and decided to throw my main butter transport ship out the window. I most certainly ate less butter as a result.

*sigh*

20160626_160302This past year I really began to branch out in experimenting with various sources of carbohydrate. I largely avoided wheat before that, aside from the occasional sprinkle in stews and gravy. So I decided to spread my cheeks and blow a nice medium winded gluten free fart over the Internets gluten dusted bible and investigate it’s pages further. I started looking for plain breads that were made with no oils. I’ll give you a dollar for each loaf of bread I found without oil (feel free to laugh and/or cry on that one).

I finally found some local artisan bread (artisan is short for hippies in garages charging high quality prices for low quality shit) at Whole Foods, had it sliced and began to nibble on it with butter. I made some grilled cheeses, some garlic bread at one point, etc. It was good, I was excited, but after a while I lost interest, it didn’t rekindle my childhood memories of bread and butter, and I’m definitely not the type of guy who wants good bread to sit down and eat a loaf of it, I just need a proper transport. And honestly I’ve never found in all these years a suitable alternative to bread and I’m not the type of guy to settle for anything but the best. So I went without it.  I moved on and began to look at approaching the bread problem myself, got a book, did research, figured out the problem, and then never followed through because of work related activities. But my plan was to work on my own starter and use long fermentation times. Stuff like that takes a lot of time to work on.

I was on Netflix one day looking for something interesting to watch and saw the Cooked documentary up there. See I really hate food documentaries, they give me reflux. But I couldn’t find anything, so I bit my brain tongue, turned it on, and prepared myself to be transformed. It turned out it was 4 episodes. I watched them all and was pretty impressed.

I liked all the episodes but the episode where they featured the Berkshire Mountain Bakery caught my eye, this guy did shit the right way and the one thing he said that I could experimentally test was the “spit test”. He said essentially that with fake bread you always have to have something to wash it down (I would agree), and that real bread causes your mouth to produce saliva as it begins the digestive process. So I looked to see where his bakery was and boy was I a happy camper when I found out he was only a few hours away.

There were two locations within 30 minutes of each other. One was like a pizza slash cafe type deal and the other was were the magic happened and the main bakery.

20160626_170426

The town the place is located in was small and reminded me more of how New England is supposed to feel whereas Connecticut seems more like a ghetto the size of a state. I grew up in a conservative religious family and my father was essentially a fanatic. When you grow up that way and your brain develops and starts thinking freely you develop this kind of weird sixth sense. You know those small towns were everybody is polite and nice but you know they are engaging in candle lit cannibalism? Yeah that kind of town where even the hippies are conservative. I can detect that 10 miles out. I can’t be sure if it’s some type of electric field I’m tuned into or the faint smell of witches burning in the air.

The purpose of this trip was the spit test to see if this bread made my mouth salivate and to decide whether or not we would place a bigger order online to store in our freezer. We tried some samples, and holy shit, not only was my mouth salivating and producing an abundance of spit, but for 30 minutes after it was like my mouth was watering. We bought some raisin bread, various different named breads, a chocolate croissant, and some other things Elyse picked out. Everything was priced much less then what I’d expect for such a labor intensive product.

20160626_170452We then went over to their pizza and cafe place. Ordered a cheese pizza and waited about 15 minutes. It smelled wonderful. At first when we opened it was kind of strange seeing actual real mozzarella on a pizza as real mozzarella when melted has almost a wet rubbery appearance that can be off putting. So we went out in the car to try it while we were driving home. Holy crap, easily the best pizza I’ve had in my life and growing up I’ve had pizza from all the major pizza regions. The pizza crust was done the same way, slow fermentation, it caused elevated spit production, and there was not lead ball sitting in my stomach after eating it.

The entire experience was enlightening, stimulating, and the kind of thing I associate with curiosity and that curiosity eventually took us on this adventure. That is the way life should be, for better or worse, an adventure.

Beyond the butter, there is the bread, and if the bread sucks it ruins the butter and that is not a good thing. There are things that happen during slow fermentation that don’t happen with manufactured starters and other methods that are used to speed up the bread making process. I think there is good reason to believe that something is fundamentally changed when bread is done right and I think there are very few people who are reading this who have ever had a real piece of bread and felt the sensation, the tangy taste, the light spongy moist texture, and the pleasure of a proper butter transport.

[Europe your bread is better then America’s but this isolated bakery just beat you with a stick.]

In my past post I talked about how when we stopped putting butter on our bread it seemed like we started having an elevation in gluten intolerance and allergies. Not only did we stop eating butter on our bread we stopped making bread right.

If your feeling dangerous give it a try if you can. They have a $50 order minimum but it can be frozen. If you are in search of a butter battle ship this is the one, see on you on the starboard side, look for the guy having the left over roast beef sandwich.

Your ideas on nutrition are superstitious

The first paragraph in the Wikipedia Nutrition article sings the following tune:

“Nutrition is the science that interprets the interaction of nutrients and other substances in food (e.g. phytonutrients, anthocyanins, tannins, etc.) in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism and excretion.”

I think the person singing that song is a bit out of tune. I think the definition promotes a sort of thinking that is conducive to an idea that we are black boxes. That given a rigid set of nutritional parameters, we can expect a sort of uniform response from the organism. Like a rat study where you have caged animals and the experiment group gets fed one thing and the other group gets fed another and they uniformly have on average the same weight gain or lack thereof in their respective experimental groups. For example, feed a group of mice the Western diet, they get fat, while the chow fed control group stays slim.

But what is wrong with the experimental design is that it fails to simulate a natural mouse-like environment. And I think most would acknowledge that. However, to get them to be honest about the implications might prove more difficult.

The evidence of this phenomena can be experienced just by pulling the blinders back, stepping outside, and taking a look around. Take a look at the culture you live in, you’ll notice that generally people tend to follow the “when in Rome” mentality adapting the lifestyle and eating habits of the natives. Yet you’ll see polar reactions, some seem to thrive while others seem to have nothing but problems.

Or in a different way you can take a group of people with the same beliefs, eating habits and sense of community and you’ll see that they generally react in the same way as the mice in the cage. Pluck one out take them to a new geographic location and things change.

Those observations point to a point I made in a previous comment that the physiological reaction of a organism depends on the context where the organism is present. And this points to the idea that there is a very intimate interaction with an organism and it’s environment.

I have no doubt that people eat in various ways to combat health problems with great success, you have COPD, eat some butter, you sneeze or feel congested or have wheat belly after eating wheat, you avoid wheat. But while those things might provide symptom relief, the question then becomes, have you solved the problem? And how can you know that you solved the problem? What is the litmus test? It’s very tempting for people to say well wheat is like antifreeze for me, people who drink antifreeze die, so I should avoid it.

But most people including those who live long and healthy lives often eat wheat, so the question should be why can’t I eat wheat, what is broken, how did I break it, was it simple cause and effect; I ate a lot of wheat and I broke my wheat digestive powers?

And then:

Do I care if I can’t eat wheat? Will I have anxiety about not being able to eat wheat for the rest of my life? Will I burden society as a whole with an International gluten-free campaign so that I can get everyone off gluten so that I can feel normal?

Will I be Paleo, sign-up for CrossFit and start a blog with a selfie showing my hot abs or ass, and try to convince everybody else that this is the right way and the rest of us sinners are going to hell (even though most likely those are opportunistic photos taken when I’m not feeling like shit)?

H/T to those of you who really don’t feel like shit.

Meanwhile the sinners are quietly eating their cheeseburgers.

To think that the way you eat is right for everyone is at the root the thinking of an authoritarian control freak who is the poster child for a person suffering the delusion that they are in control of their life. When most likely that person is anything but in control of their life, feeding into a self-fulfilling delusion that the more variables they can control in their life the more they can skirt the issue of actually having a life, living their life, and enjoying their life.

This post has been overdue, as for the past year I’ve been experiencing paradigm shifts in my thinking as a approach the world in a more honest way. And approaching the world with peeled back blinders is always a good thing even if you have to put a foot or two in your mouth. I am not content with fossils.

“Possessing opinions is like possessing fish, assuming one has a fish pond. One has to go fishing and needs some luck—then one has one’s own fish, one’s own opinions. I am speaking of live opinions, of live fish. Others are satisfied if they own a cabinet of fossils—and in their heads, ‘convictions.’” ~Nietzsche

Although my cabinet of PUFA fossils is well intact aside from flirtations with animal products that tend to contain higher amounts of them :)

Over the next few months or whatever I’ll be plucking out old blog posts and updating things based on new information and why I’ve changed my mind (but the old blog posts will stay up for illustrative purposes). It shouldn’t be too hard as my views on saturated fat and polyunsaturated fat are still the same and I still am metabolically focused. But some of my views on carbohydrate have changed dramatically. Bear in mind that my blog is personal, everything I do is not 100% transferable to empty vessels, but I hope it still can provoke the asking of questions and generate criticism good or bad.

More to follow soon. Thank you for the continued questions and comments during these dark times. Till then have fun!

Best wishes,

Great quotes

“Everyone in nutrition is influenced, more-or-less unscientifically, by their own dietary choices or those of their culture. On the one hand we have a clique of mandarins who were “born on second base and think that they’ve hit a home run” with regard to diet and metabolic health. On the other hand we have people such as Tim Noakes, on trial for his opinions as I write, who have overcome metabolic disadvantages with the help of diets that have included the prohibited elements. By any objective test, the second narrative should be the more convincing, but perhaps not in a society that worships unearned success. It is obvious enough that the selection and appreciation of evidence in the DGAC process is distorted by unthinking acceptance of the first narrative. We owe a real debt to Nina Teicholz for bringing this out to be debated in the public domain.” ~George Henderson

“In a community where everyone has a divergent opinion on what’s healthy and what’s not, what’s obesogenic and what’s not, which diet is best for which people, under which circumstances, etc., I can’t help but wonder if the nutrition and metabolism community might be better suited to follow the path of the aforementioned 12% minority [of physicists], and just shut up and calculate. Forget about what we think we know, and just focus our attention, instead of on ideals, on generating better, more generalizable data, utilizing solid statistical methods, carefully avoiding common missteps (like overemphasizing p-values, running too many significance tests, and using relative risk ratios rather than absolute risk and NNT, among other things), making all the data available for objective re-computation, analyzing quantifiable changes in biochemical assays, and more.” ~Ian Lane

“One thing’s for sure, it takes a curious blend of ignorance, cognitive dissonance and confirmation bias to become convinced that salted-sugared skim milk and OJ is the ‘best’ way to attain the highest possible level of health.” ~Shane

The Will to Survive

I was reading Danny Roddy’s latest post about a fish tank or something (just kidding Danny, I Love You) which I thought was quite good and remembered this thread from a while back.

Gosh, were we all so immature in those days. The growth we’ve all experienced over the years has been amazing.

This naturally brings me to Dr. Peat. I once wrote quite a bit on the Ray Peat Forums, eventually was banned and moved on to grow into addressing problems I deemed more important. The thing that annoyed me with the cult like Peat following was that they reminded me too much of religious people. They interpreted his work as if it was biblical scripture, and when something didn’t fit they would endlessly try to justify their position or just ignore it or say that you don’t truly understand his work. Not much different then groups of church people and their endless interpretations of biblical scripture that pit themselves against each other.

What initially attracted me to Dr. Peat in the early days was his view that energy and structure are interdependent, something which at the time as I was studying mitochondria, struck a chord with me and gave me the confidence that the way I was thinking about things was something worth pursuing. My armchair background in physics and other sciences, and as Danny Roddy put it in his article in so many words, a pursuit for a universal theory, whirl-winded me away from the cult-life and towards synergizing my own ideas most of which aren’t published publicly. There are some people who I confided in and shared a portion of my work with who were also Peat “followers” who said in so many words “that this is the light at the end of the tunnel”, the thing that will bring everything full circle. That was a few years ago.

Such compliments scare the shit out me. And after which, I became reclusive to examine the finer details. Exceptions and outliers are my kryptonite. It is all too easy to generalize and miss something. Which is why to this day I haven’t published my general theory on the nature of nature.

Recently I was listening to the KMUD interview with the makers of “On the Back of a Tiger” and Dr. Peat. There were a lot of good and positive things said. But the one thing that bothered me was that the host kept asking what Dr. Peat thought, asking for an opinion is not a sin, but my impression was that the host wanted verification for the work that others have dedicated the majority of their lives studying, annoyingly so, as if in one swift word Dr. Peat could invalidate their work. I find that mentality troubling.

That mentality is the antithesis of Dr. Peats work. It is the opposite of thinking, the opposite of stimulating the organism. It is authoritarianism.

This might be confusing for some as Dr. Peat is definitely is anti-authority. To illustrate what I mean here is an excerpt from my work about the concept I’m trying to convey:

“Entrenching is not the new idea but rather the aversion to self-confessing an error approaching things in a new way.  The conflict does not arise out of the new idea but arises out of the individual. These individuals place too much power in words and ideas. These people are the real dangers in society—not the originators of new ideas. It takes much more than an individual to do anything with a dangerous idea just as it takes much more than an individual to do something with a useful idea. Ideas have to be stated and different people must implement them to become a useful or dangerous reality.”

In other words, it is the followers the perpetuate dogma. Not the originator of the idea. That is, the state of the sciences and its application is not the result of authoritarianism per se, it is the complacency of people that facilitates authoritarianism. Governments and institutions become authoritative because people are poor consumers. They are poor consumers because they have no self-confidence, have a lack of curiosity, and/or they lack the belief that they can think for and figure things out for themselves. This mentality is self-reinforcing and over time systems in place become more and more authoritative and resistant to change. But the solution is not to destroy, the solution is to evolve. Nothing good really comes from destruction, usually repetitive cycles between the garden of Eden and Doomsday.

Once a follower understands that it is they who facilitate dogma, they are faced with a multiple dilemmas:

“What is difficult for the entrenched individual is not the new shift, but the shift that points to years or a life wasted and genuine interests forsaken. There is a saying: “You can’t teach an old dog a new trick.” Few people are so downright stubborn. But these defining qualities are common enough that most of us are familiar with these individuals.”

“And what follows is a revolution in cultural knowledge to try and rationalize why we did things the way we did in the past and why it is justified to change things for the future. Radicals entrenched in their beliefs usually, but not always, die in these shifts of thinking; literally or sacrificing the personality. Being a martyr for a particular paradigm has never been a personally natural inclination. When the individual is cornered and experience is conflicted with lacquered beliefs, the individual is faced with options of entrenching themselves behind belief or taking steps to evolve in another direction. It is the collateral damage of opposing extreme views in groups of people that often drive cultural evolution. At some point we must put aside belief and continue moving forward. A fight to the death is not a viable option except for the delusional.”

The proverbial foot in mouth is not an easy situation for anyone. Easier for some harder for others. Once somebody is convinced they are on to something and build a model around it for their livelihood they are doomed to confirmation bias. They themselves become the antithesis of life. It is why to this day I refuse to put a price tag on sharing information and ideas. It is crookery. Dishonest. And egotistical. It is what got us into this mess in the first place. It’s like the FDA, maybe the founding intentions were good, but it evolved into a completely different monster, that is the nature of trying to protect people and/or inform them, bias almost always follows, and where there is bias there is destruction.

A lot of people who should be scientists and have the charisma and passion to change things don’t become them because they are disenchanted with the system in place. What cowards. If you want to change something you have to participate and help the system to evolve. You do your small part and help to change things for the future. Being reclusive from that hostile environment only demonstrates the compliant temperament to bowing down to authority.

Being critical and passive demonstrates one thing, it demonstrates the type of energy flowing through you. An energized organism is resistant and resilient to stress, thrives, and has the ability to fundamentally change things, be it themselves or their environment. For example, Dan Wich noted my ability to levitate chairs with large amounts of saturated fat.

For years I thought that avoiding stress was healthy, to my surprise, the opposite occurred and was demonstrated to me over and over again, during the most supposedly stress free portions of my life I suffered from the most debilitating health issues. But as I began to participate in life more and more, confronting adversity, my health, my spunk, my problem solving abilities, etc., all rebounded regardless of my diet, regardless of how much sleep I got, regardless of everything just short of exhausting myself, stress (thinking is stress for example) gives life purpose.

Caffeine

I began to question the “positives” of caffeine when I was reading combination therapy studies where caffeine alone was not effective but caffeine plus a therapy was more effective than the therapy alone. That raised an eyebrow for me. Perhaps it is useful to know how compounds exert their effects before we say something is good for you.

Caffeine as are most methylxanthines are potent inhibitors of respiration. There are also a number of negative hormonal side effects with the digestive system leading me to wonder e.g. if some perceived food intolerances are caused by heavy chronic coffee consumption.

When I see a compound inhibit respiration and a shift towards glycolysis I automatically think insulin. Caffeine effectively increases insulin. This would have the effect of suppressing beta-oxidation to some extent causing a stress response which would temporarily increase the RMR. Anytime respiration is suppressed acutely there is a temporary increase in the RMR to restore NAD+/NADH ratios. Caffeine probably inhibits respiration by shifting the cells towards glycolysis increasing NADH which essentially creates the Crabtree effect. It happens that the Crabtree effect causes cells to uptake calcium which eventually causes apoptosis. In cancer this would be useful. Essentially the caffeine is stressing the cell making the pharmaceutical therapy more potent.

Some people report that when they give up coffee there is a period of time where they feel excessively tired. My opinion is that when chronic stress is reduced this symptom is to be expected.

Dr. Peat mentions caffeine being an “adaptogen” he is somewhat correct in the sense that acute caffeine consumption would cause a temporary increase in RMR (stress response) causing weaker damaged cells to follow through to apoptosis. Caffeine does stimulate autophagy. Basically a sort of ripple effect through the organism i.e. a window cleaning with a squeegee. When insulin increases the thyroid hormones tend to increase as the thyroid hormones participate in degrading insulin thus restoring organization through increased beta-oxidation of fatty acids.

But chronic consumption could be maladaptive. On the surface there seems to be a loss of heavy caffeine consumers in centenarian pools. Fat, nicotine, chocolate, and alcohol (although heavy alcohol consumption does as well skew NAD+/NADH ratios) seems to be far more common with coffee consumption being a cup or two a day for those that do drink it and happen to make past their 90’s. But that observation is probably biased because I haven’t looked that hard.

Chocolate also contains methylxanthines but the stearic acid and other SFAs probably offset the negative consequences.

For those who look at metabolic rates, there are a lot of compounds that increase the metabolic rate. A lot of lethal substances are on that list. I think that it is important to look at the context when recommending chronic consumption of said substances as an adaptive stress response is something quite different then a chronically induced state of hypermetabolism. Animals that live long such as the naked mole rat have low RQs, are insulin resistant, and Vitamin D deficient. During hypoxia (e.g. altitude or underground) humans react physiologically, fatty oxidation increases and ketones increase. Fatty acids, lactate, and ketones are protective in low oxygen environments.

Then there are those who are better or worse at metabolizing caffeine and other xenobiotic compounds, I would guess this would determine tolerance to such compounds as well as what “dose” would mediate a beneficial hormetic response.

In the beginning I mentioned that I began to question the “positives” of caffeine. I want to define “positives”. Because the idea is not to recommend that you should axe coffee the idea is that just because we see good evidence of a substance with benefits doesn’t mean we turn off our brains and forget to ask why are there these benefits, how does the substance mediate its effects, how can I best use this substance without interfering in general with my enjoyment of a substance which possibly could be a double edged sword.

So having a cup or two of coffee a day is probably adaptive, but if you are drinking “50 cups of coffee per day” there is probably something extremely wrong with you.

Aside: Logic and stress

There is this idea out there that blows my mind. It’s the idea that somehow being a baby is stressful or harmful.

That a rapidly growing and developing baby who is in ketosis and is consuming a protein-restricted-low-carbohydrate-diet i.e. breast milk is somehow in a state of stress. That if a baby never weaned after some magical age from breast milk that eventually they would go from a healthy growing thriving baby to developing the following symptoms:

  • Gastrointestinal disturbances (diarrhea, vomiting, nausea, constipation, GER)
  • Inflammation risk
  • Thinning hair/hair loss
  • Kidney stones
  • Muscle cramps or weakness
  • Hypoglycemia
  • Low platelet count
  • Impaired concentration/cognition
  • Impaired mood
  • Renal tubular acidosis
  • Nutrient deficiency
  • Disordered mineral metabolism
  • Poor growth in children
  • Skeletal fracture
  • Osteopenia/osteoporosis
  • Increased bruising
  • Sepsis, infection, bacteria overgrowth
  • Pneumonia
  • Acute pancreatitis
  • Long QT intervals
  • Cardiomyopathy
  • Shift towards atherogenic lipid profiles (including hypercholesterolemia and hypertriglyceridemia)
  • Heart arrhythmia
  • Myocardial infarction
  • Menstrual irregularities and amenorrhea
  • Death

If you are to believe the high-carbohydrate-low-fat people and their interpretation of physiology that is the implication at the end of the day. That somehow after weaning we fundamentally transform into an organism which once had a metabolism that predominantly utilized saturated fat, ketones, and lactate to a metabolism that to be in its optimal state post weaning should now utilize primarily sugar.

It’s like a bad joke. I’m not into the habit of believing that we are screwed before we can walk if we can’t find and climb an orange tree. Typically it is us who give ourselves the reach arounds.

Somebody skipped the part where saturated fat, ketones and lactate support rapid growth and in fact are necessary for normal development.

Anyway enough with that crap (I originally wrote this post without the symptom list and then came across that ridiculous post).

Some people get all tickled when you say you are doing it wrong. I’m not in the habit of saying your doing it wrong but clearly babies are doing it right. Shrug. I dunno.

Moving on:

Curiosity, movement, abstract thinking, problem solving, and imagination support brain development, idleness retards it (lowered stress). Anything that puts a demand on energy is stress.

People view stress as a bad thing, it is chronically, but I think of the organism more like a “muscle” much like exercising the neurons in the brain leads to improvements in cognitive functions. Perhaps we should look at acute stress more like “exercise”. After all it would be a more intuitive paradigm.

Energy and Structure: Protein

In the past few days two people have asked me what my thoughts on protein are. And one person asked about my caloric intake. I am particularly active and considering that context I thought I’d cover my reasoning on why I restrict protein. Honestly I’m past the restrict part I tend to eat low protein easily because I hate that overly full feeling like there is a ball of lead in my stomach after a larger-than-life-everything-is-bigger-in-America-steak.

My rationale comes from two angles, the first one considers the mitochondria and respiration and the second angle being growth and metabolism.

The most intense period of growth and metabolism during our lives is when we are babies. The brain is developing, organ systems are developing, etc. It’s actually quite amazing to think about. And I say actually because I think a lot of people don’t consider how amazing that stage of life is. A lot can go wrong.

What are the primary exogenous metabolic substrates in growing babies? For simplicities sake: saturated fat, a sprinkle of polyunsaturated fat, a sprinkle of protein and carbohydrate. There are some other exotic lipids in breast milk and some bacteria but again we are just going to do a surface overview.

From those raw materials the baby develops. And thinking about that is a trip. Babies that are breastfed from birth to 2-5 years old continue to rapidly develop and I think it is fairly well established that breastfed babies have a leg up in a lot of different areas regarding the ability to cope with stress, having higher potential IQ’s (although nurture can ruin that), being resistant to disease later in life, the list is a long one. But wean a baby early or feed them formula and all the sudden you start to see negative consequences.Digestive issues, retarded growth, underdeveloped brains, allergies, mood swings (I’ve always found the disposition of breast fed babies compared to early weaned babies interesting).

Those points there should if anything cause one to pause when thinking about macronutrient ratios and growth and metabolism. Especially in the circles that focus on having high metabolisms. There I must point out that babies have low respiratory quotients, elevated ketones, elevated lactate, etc. I should also point out that breastfed babies are more symmetrical.

The most intense period of growth and the period in life when our metabolisms are probably at their peak are when we are babies.

Now lets think about all the fat on babies. Around 30-35% give or take after a few months. Muscle mass? Not much. But parents who breastfed their babies know that babies are impressively strong for their size and surprisingly coordinated when one considers what kind of coordination it takes to walk upright. We tend to not think of walking or crawling as something impressive but that is only because as adults we take it for granted.

Strength in my opinion is more so a CNS issue. If you watch Olympic lifting especially the feather weight classes what you see is something pretty impressive. You see stick figures lifting 2 or 3 times their body weight over their heads depending on the movement. How is that possible? My opinion is that for the most part strength is a measure of the efficiency of the CNS to fire muscle fibers in a coordinated and explosive fashion. The more accurate the CNS is with activating muscle fibers the greater the strength.

In general you have sarcoplasmic and myofibrillar hypertrophy. Sarcoplasmic hypertrophy is probably stressful to the body whereas myofibrillar hypertrophy is adaptive. In general when cells take up excess water it’s probably a negative thing. This is why in endurance athletes you often see enlarged hearts and after a while they drop dead.

If you watch kids play in a natural setting it’s almost always myofibrillar hypertrophy that is occurring.

Protein is more dense than water and babies almost always feel heavier than they appear.

So as babies we are growing and are getting strong due to myofibrillar hypertrophy. Strong despite the fact that when we are breast feeding our protein is lower than what we’d expect from adult studies on protein intake. Yet protein synthesis is still obviously occurring and we are still growing and still developing.

Again the body fat percentage in general for babies is around 30-35%. Strength is a measure of the accuracy of the CNS. And increasing strength primarily develops from myofibrillar hypertrophy. Yet the protein content of breast milk is low.

So there a few questions you have to ask yourself. Do these things regarding strength and protein intake agree or disagree with the literature on adults? Has anybody actually shown that increasing protein intake (alone) correlates with increased strength in a dose dependent manner (obviously protein intake does need to be adequate but outside of that the question is interesting)? Why is it that the strongest people in the world almost always look fat? Is there a shredded beast under there? Or is their strength a function of their body fat percentage and more importantly the body fat composition (cough, of the saturated sort) and the ability of their CNS to recruit their muscle fibers? Would they be as strong if they shed the fat? Would the longevity of their careers increase or decrease with leanness or increasing body fat?

If at the end of the day you believe that protein intake (outside of adequate) has nothing to do with the ability to increase one’s strength then you are left to look at the first angle, respiration and/or cellular generation of energy, which is without a doubt going to in part determine the ability of your CNS to fire your muscles, whether it be saturated fatty acids, lactate, creatine phosphate, etc.

A misconception is that the cell is a bag filled with water and all the organelles are just floating around and that the cellular membrane is basically all lipid. I would say a lot of scientists recognize the gel like nature of the cell but at this point we just haven’t gotten to the point where people are making a big deal about it, but the evidence is there. If you look at electron micrographs of cells you can see that this is actually not the case, cells are protein rich. In fact the cellular membrane is to a great degree made of proteins. I’ve seen some extremely varying estimates on the protein content of cells but at this point I’m more comfortable with saying that the cell is not a bag.

The next question then is if that is true (cells are made of a lot of proteins) and a growing baby is indeed growing and is on a low protein diet where is all the protein coming from? Where are the raw materials for protein synthesis coming from? Is the protein in breast milk enough? I would say it is enough and I would bet the farm that outside of adequate protein intake more is not better.

That is my line of thinking. I start there. Essentially looking at things from a functionality point of view rather than theoretical needs or aesthetic goals. The ability of excess amino acids to feed into the TCA cycle concerns me in the sense that I want saturated fat in my mitochondria, or maybe some ketones, or maybe some lactate or glucose were needed (Peter knows more about that than I do). I don’t like the idea of swollen mitochondria.

It does seem to be true that high meat diets can be conducive to leanness (so can vegetarian diets) but when I see things like that I see more of a starving to death syndrome, the undesirable substrates cause fat loss because the mitochondria are trying to maintain respiration and from the organism view, trying to maintain form. And I would say to some extent that the thermogenic quality of eating excess meat probably is at least in part due to elevated fatty acid oxidation which might be okay in the short term but long term I don’t like the idea. There is nothing wrong with having a high body fat percentage if it is the right kind of fat. It’s beneficial and you’ll probably feel better. We’ve all seen babies, we’ve seen some babies that are fat in a bad way (formula fed) and babies that are fat in a good way (breastfed), the breastfed babies fat is of a different quality.

Aside: This post is geared towards flesh meat, I have yet to think about whether protein is protein, or if denaturing proteins e.g. fermentation makes a difference. I also did not consider in this post the ability of the gut bacteria to ferment amino acids.

That’s all for now.

Cravings

I wish you all a happy winter solstice no matter what variation theme you subscribe to.

It seems fitting to write about cravings. With the New Year around the corner there will be plenty written about cutting calories, losing weight, exercise, colon cleanses, juicing, coffee enemas, and all that Bah Humbug!

I am in the middle of writing a post on the Crabtree effect and in the process I started thinking about cravings.

I’m always thinking about the mitochondria.

We often say that certain energy substrates are addicting. That might be so, but I find the explanation unsatisfying. Feeding a human and/or a lab animal sucrose and noticing addictive behavior and showing an fMRI of a brain lit like a Christmas tree demonstrates cause and effect but it does not answer the question: Why?

I believe the brain can be loosely described as a blend between a psychopath and sociopath. It will whittle your body away in the name of itself while you grow tumors on your arms and legs. It will keep you up at night if you didn’t eat enough. It will send signals to hormone secreting sites on your body to increase this or decrease that. It will make you feel bouts of mania and it will make you depressed. It’s all very exhausting. It brings me back to the point in an earlier post that hormones are background until inefficient energy substrates are introduced AND/OR the organism is put into a context where there is a need for an acute response due to increased energy needs e.g. physical stress, psychological stress, injury, etc.

But what mechanism is responsible for this, what signal is the brain receiving that causes all of these symptoms? I believe the answer at the end of the day is simply inhibited mitochondrial respiration i.e. hypoxia and that the brain senses this. That is another key, that the brain senses this, although it can be quite selective in acknowledging it with its psychopath/sociopath mentality.

I think it is fair to say that the brain can sense inhibited respiration globally and locally. Local inflammation is an indicator that the brain really is aware that a toe is a toe and that when you get kicked in the balls your balls hurt not your eyes, although they probably will water a bit. Why do your eyes water when you get kicked in the balls? I don’t know but I think it is a good indicator that although we are amazing creatures we aren’t perfect. I think there are examples of other organisms with more accurate nervous systems. We’ll get there though eventually if we don’t kill ourselves first.

But you have to ask yourself why is it that if I cut off my arm my whole body feels the pain and not just the site where the arm is cut off? Is it because your brain senses a possibility of death or is it because your brain knows that you will have one less hand to stuff your face with?

If you think about that for a moment it’s quite amazing. If we assume that cravings are a result of inhibited mitochondrial respiration we can then begin to explore the cause of cravings and perhaps why certain cravings are prevalent.

Fat is all around us in the Western world. So are carbohydrates. In our culture we associate carbohydrates with energy. I witness this conditioning on a day-to-day basis with my coworkers who ask: “If you don’t eat carbohydrates where do you get your energy from?”

When I explain to them I get my energy from fat they are baffled. “Isn’t that bad for your heart?” Contrast that with traditional times where fat was a prized resource.

When you consider that then you can begin to contemplate cravings. I don’t believe that menstruating women in artic cultures craved chocolate. I don’t know maybe during menstruation the women had secret stashes of berries.

Silly isn’t it.

So why do we crave sucrose? Because there is strong enough of a cultural convention and an association with carbohydrates and energy that during stress this is what we reach for naturally. If that association was different we’d reach for the butter.

However, the difference is that butter maintains respiration. Sucrose does not, in fact over time it reduces mitochondrial density and respiration so that a craving for sucrose produces a perpetual addiction in the name of trying to maintain respiration.

For so many years we have believed that butter and fat were a guilty pleasure, we forgot that in reality it was a superior energy substrate. So we ate it when we “caved” but believed at the same time it was clogging our arteries. We slowly conditioned out of ourselves our fat loving selves by believing that it was bad for us and thus losing the association between fat and energy and stability.

Now we believe that sucrose is good for us, we believe that the swings between hypo- and hyperglycemia are normal and all the peculiar behaviors associated with it. We believe that no matter how depressed or fatigued we feel that that is part of life and it is acceptable so long as we don’t die of a heart attack. In effect, because we fear death by heart attack we have allowed ourselves to be conditioned into believing carbohydrates are healthy even while we proverbially attach electrodes to our nipples every time we drink a bottle of Coke.

When you start thinking about respiration and the Crabtree effect you start believing that the idea of “moderation” is a last ditch effort by commercial enterprises to perpetuate a legacy. I believe that people in the Western world are unsatisfied, they might not know it consciously yet, but I think the flux of TV cooking shows where Chefs prepare real food is a sign that people are hungry for something real. They just don’t know why and they have forgotten how to cook. All they know is that it fat dripping off of charred meat looks good. But I would see things in a “mystical way” like that. After all I’m a Jungian and I subscribe to Sheldrake’s morphic fields. “We” want to survive.

Olypmic weightlifting, this is not a post on Olympic weightlifting

Off topic. I read some posts on the pseudonutritionosphere that triggered some early memories and thoughts.

Thinking back I was always an active child, both mentally and physically. And both seemed to enhance each other. Experiences like that can help a grown man make sense of things sometimes. In my teenage years I played a lot of recreational basketball on the weekends. I also played baseball. I also did a lot of cycling, and there was a period I remember in middle school where I would run around the track during recess. I never really fit in with the physical types and I never really fit in with the mental types. In high school, I went to football camp in my freshman year, and then played on the football team for most of the season but quit towards the end. I was also in the choir from elementary school through high school. If I recall correctly I stopped singing at the end of 11th grade. Then I got a guitar. Fast forwarding a little bit into the time while I was in the military I had a small studio set up and I recorded a lot of music. Eventually I found the drums. I like the drums. In my mid-twenties I was a marathoner for several years before I discovered lifting weights.

You see although I was physical and into doing physical activities, I was not into the sports culture. I did those things because there was an element of challenge that stimulated me. So if you asked me the rules or what is what I still don’t know, I’ve never had an interest in those aspects of “sports”. My thoughts were just give me the ball and I’ll do what I need to do. I think things like that are good.

After that I discovered Olympic weightlifting. I’m almost 32 now and still do the Olympic lifts everyday, sometimes twice.

In the old days Olympic weightlifting was an old mans hobby. Looking back I can see why. It requires a certain amount of patience that is hard to ingrain into a twerp without having a lot of supervision. And that is not a bad thing, you have to repress curiosity and introduce structure for a child to do something so mindless because at that point Olympic weightlifting seems rather pointless.

When most people think of weightlifting they think of crossfit (I’m not going to even legitimize that with a capital letter) and bodybuilding.

Those things are not Olympic weightlifting. At least not to me. And because this is an opinionated post it’s probably wise to keep that fact in mind.

I think Olympic weightlifting is one of the healthiest physical hobbies you can engage in. Why? No scientific studies here, not that there aren’t any, but because it’s not important. So why is it one of the healthiest activities besides drinking wine, eating chocolate, and smoking or Snus? Or eating beef ribs? Because it makes me feel healthy. That’s why. That is all there is to it.

Now for you it might be reading a book, or going for a stroll in the park, or injecting a dose of insulin. Fair enough.

When I was growing up, and I’m not old by any means, children still had hobbies. We started things on fire, we played in the swamp, we were outside past the time the street lamps came on, we burned slugs in gasoline, climbed roofs, jumped out of our windows at night, we wrestled, and we still did a lot of things that are typically associated with the golden age of American culture. A lot of stupid shit. To be fair, I was on the tail end of that, right as we began to transition from board games to their digital counterparts. So even though my friends typically had hobbies there were also a lot of children who were just learning to mold the couch to their asses.

I write a bit, o.k. mostly about material things like saturated fatty acids, graspable things you can hold in your hand to improve your life. And while those things can go a long way to improve your life. The recipe will never be complete without some missing ingredients:

Getting a life.

I have part of a book sitting on my hard drive collecting digital dust. The book as far as I can tell is my most original idea, I’m just not ready to finish it yet. I’m still testing it. So far it has stood up to several years of new data. As I’ve said before, I’m curious about exceptions, and because my idea is important to me I want to cherish it a bit, and if it should happen I’m wrong, then I will let it go and will never publish it. I think in one of my posts on PUFA that I never finished the second part to I even eluded to the fact that some people seem to do fine and live a long time with it, or get away with it. Of course that is only happening because they are maintaining normoglycemia. Are they lucky? Yes of course in their eyes. But I see something else at play something very material and explainable.

That is what the book is mostly about, not how to get a life, but why having a life matters tremendously.

If you spend a lot of time arguing on the Internet, it’s time for you to stop. Why not start your own blog and share your ideas with others. One of two things are going to happen, either a) you’ll loose interest and realize that the only reason you are on the Internet is because you like to argue with people or b) you’ll start exploring things on your own and be more likely to discover solutions to your problems that will give real change in your life. You’ll become a scientist in your own right specializing in the study of you. Perhaps you might make some breakthroughs instead of using other peoples paradigms on yourself.

Do you know what being sedentary does to oxidative stress markers? And I’m not just speaking of being physically sedentary I’m talking about an idle unfulfilled brain more concerned with arguments instead of exploration.

May the force be with you.

Ketosis

You’ll notice around here that I sometimes post papers on the usefulness of ketones yet I rarely talk about ketosis. The reason is that I think ketosis is secondary to the main point. The main point being: run your metabolism off of saturated fatty acids. I do not think that the benefits of a high fat diet stem from being ketotic I think the benefit comes from running your metabolism on fat, even high fat PUFA rats do better than low fat rats when we are speaking of longevity. And I think that I’ve been consistent about that, the saturated fat bit, to the point of ignoring a lot of other things people seem to care about, which I do on purpose because I think it really doesn’t matter.

It’s useful to think of the word “metabolism” and what it really means. I think we can compare this to Cogito ergo sum, “I think, therefore I am” or “I am thinking, therefore I exist”. Do you really think that if you are eating a high carbohydrate diet that “you” exist? What exists in that state is your hyperglycemic self and your hypoglycemic self. Somewhere in the middle you exist, that is where you exist in pure form, that is where your metabolism lies, an efficient one at that. The balancing act between hyper- and hypo- glycemia is amazing. It’s what helps to maintain “form” i.e. you. The things your physiology does to try to maintain OXPHOS and suppress the Crabtree effect thus preventing you from degenerating into giant mass of primitive cells is not appropriately appreciated.

When free fatty acids rise during stress or during sickness or when anything bad happens that is a signal, a good one, that your physiology is trying to maintain form, trying to maintain you, if that doesn’t happen or you block it, degeneration follows, much like when you take statins to try to lower cholesterol. This way of thinking, that because this or that rises during stress or bad times therefore this is bad is completely ignoring the mechanisms that caused the flux in the first place.

It’s like saying the ball dropped because I opened my hand and let it go, without considering gravity and the impact it has if you opened your hand in zero gravity or on another planet. It goes right back to the cause and correlation thinking that a lot of people spend their time pointing out and arguing against.

Judging by comments and walking around the web I think that some people have this idea that if your cells are not running off of glucose then your cells are running off of ketones. The misunderstanding being that if you aren’t feeding your cells glucose that you are eating a lot of fat or glucose deprived and then, that fat (dietary or stored), is being converted into ketones and then being oxidized by your mitochondria. That is a misguided black and white understanding of metabolism.

Your cells prefer to burn saturated fat. End of story. They are happy that way. Every cell in the body that has mitochondria can and does prefer to burn saturated fat. End of story.

If you think “high fat diet” and then automatically think “ketones” you’re missing the point.

Ketones are not a dose dependent fuel source i.e. the more you have floating around the better. I detect a level of lipid hypothesis trains of thoughts when people talk about ketones. For example, some people still believe that low cholestorol is good and that more is bad, without considering what is actually causing the flux. The same is true I think when people are thinking about ketones, the context is not considered.

Fructose: aneurysms and atherosclerosis

A while ago I wrote my thoughts on aspirin.

Recently, Joe asked: “If a large part of a chimpanzee’s diet is fructose, why are they not dying from any heart or aneurysms?”

It’s a good question. But I would ask in return how do we know they aren’t?

In the wild animals get sick and die just like we do. Only we are less likely to take notice because they have no newspapers with obituaries or anyone to do autopsies on a regular basis so we can investigate the cause of death. I would guess primates die all the time and are left behind where they return to the earth. I would also say that sick animals that are burdensome to the group would be left behind as well.  The San people did this as well if I am recalling The Old Way correctly.

Because of the lack of autopsy reports done on Chimpanzees in the wild it would be hard to know either way. But we do have Zoos. And autopsies are done there on occasion. Still we might say that the diet is a bit different from what a certain animal might eat in the wild. True. However, I think fructose is uniquely harmful. And I think that animals who eat a lot of fruit will have some of the same problems humans do with fructose.

But then we have the diet thing. The diet we feed them in the Zoo and then the diet they would eat in the wild. That’s a problem. But really, we can kind of work around this by say comparing the Chimpanzee to other animals say the Gorilla or Sheep which both ferment their food to short chain fatty acids. So perhaps we can compare animals that live in captivity to see a difference.

I have a couple papers on this topic. But I want to look at the pathology which is the most revealing. Lets start with the Chimpanzee:

2014-11-23 18_51_14-Mendeley Desktop

O.k. tea and milk? I doubt Chimpanzees are brewing tea in the bush. Nonetheless, I would think these food choices are something Dr. Peat would agree with. Nix the tea.

2014-11-23 18_53_03-Mendeley Desktop

And:

2014-11-23 18_55_37-Mendeley Desktop

Interesting. Now lets move to the other animals that eat a lot of leaves and grass and other roughage and convert it into fat.

2014-11-23 18_57_04-Mendeley Desktop

Interesting. What about a sheep? Those are probably fed pretty “normally” even in captivity.

2014-11-23 18_58_43-Mendeley Desktop

So we have one Chimpanzee, one Gorilla, and 122 Sheep. Is this enough data to get a realistic look into what is happening in the wild? Maybe for the sheep it is a better sample size.

I don’t base the harmfulness of fructose totally on macroscopic studies. I’m thinking more at the cellular level i.e. Crabtree effect. And thinking like that, this paper is convenient and fits with my bias.

But we have other omnivorous species of monkeys as well that tend to eat what a lot of folks would consider healthy.

First, I’m always surprised that people read my blog, I don’t get a lot of traffic and there are a lot of people who are smarter than me and have fascinating ideas. True, I only read their blogs because they happen to draw similar conclusions or confirm my own ideas but they are miles ahead in their concrete understanding while I’m left to daydream and theorize.

I thank those who have commented and asked questions it only goes further to deepen all of our understandings, both directions.

I respect your privacy, however, I dislike anonymous comments or comments with your name as an organization or business and comments with fake email addresses and websites. I give you my name and details of my personal experiences (see “About” page) and you can freely contact me. I dislike off point comments or comments that don’t contribute. I dislike argumentative claims that aren’t cited.

I want to encourage “realness” here. Use your name (capitalize the first letter), you only need your first, I want a more personal experience. I want you to be an individual and stand by your comments or expressions or questions. I want to know the people who read here.

Thyroid function and saturated fat

A few years ago I came across this letter (Kasper, Schonborn, & Rabast, 1975). I was still in Germany at the time and still fiddling with carbohydrates. I knew at the time that saturated fat increased thyroid hormone production and promoted an optimal metabolism because I was outside in the cold doing a lot of running and when my carbohydrates got a bit higher than normal I wouldn’t be able to run in freezing weather with shorts, no I’d have to put the thermal tights on thus reducing me to a grade B bad ass instead of grade A.

I remember this bit catching my attention at the time:

clip

I filed it away in my brain.

Shortly after I remember coming across this paper that proposed that iodine deficiency may be caused by an increase in carbohydrates (Kopp, 2004). This seemed to fit in with the theme: those energy substrates that are efficient AND optimal are so because they require less overall cofactors to be oxidized and because they are the exact type of resource “desired” by the mitochondria. Typically efficiency is the ratio of useful output to the total input in a system. Sure mitochondria can oxidize other substrates, however, what you find is that those substrates namely the polyunsaturated fats and carbohydrates tax the entire organism bringing into the picture those hormones that otherwise would be background which typically increase the need for more energy. That bit there—that hormones are background until undesirable energy substrates are brought into the picture—is a key point to remember for future posts.

Recently I came across this paper (Yoshimura, Hori, & Yoshimura, 1972):

thyroid

I’ve come across several papers looking at the effects of macronutrients on thyroid hormones. The pattern is that fat has the greatest impact on thyroid hormone production and that carbohydrate while it can temporarily increase T3; the increase in T3 caused by increased carbohydrate consumption is actually a protective measure, a symptom. A symptom that I think is best to avoid. Interestingly fat reduces anxiety when compared to the other macronutrients which in my opinion points to stable thyroid hormone production (Prasad & Prasad, 1996).

It has been shown that carbohydrate can increase RQ. Though this is often not clear cut it is the general trend that RQ increases with carbohydrate consumption. This is in my opinion a result of the Crabtree effect.

When carbohydrates are consumed T3 increases which results in an increase in fatty acid oxidation. This is curious because one might be so inclined to expect an increase in glucose oxidation. Instead what happens is that fatty acid oxidation increases and so does DNL. Essentially carbohydrates are being converted to fatty acids, insulin is raised and the surplus of fatty acids is being stored, T3 if it can stay elevated long enough tries to bring back energy balance by burning fatty acids. Of course overtime this breaks (pathological insulin resistance coupled with thyroid disorder probably leads to ketoacidosis) and results in metabolic derangement not unlike how the pancreas breaks after a few decades of hyperglycemia. The solution to this problem is to eat in a way that prevents the problem in the first place.

T3 also happens to stimulate mitochondrial uncoupling, the uncoupling effect is partially indirect and the result of burning fatty acids. Uncoupling is for another time.

I think that when you base your diet off of saturated fat that ketones and glucose are spared in the right amounts for the tissues that desire them, much like in neonates. I think that aging is mainly a defect in fatty acid metabolism not glucose metabolism. I think this is why our risk for cancer increases as we age, again Crabtree effect. Thyroid hormones keep the body organized i.e. saturated fat as the predominate energy substrate keeps the body functioning properly, carbohydrates cause disorganization. For the most part people who live a long time like their fat, and when you see an exception my opinion is that they are going the naked mole rat route, they are eating carbohydrate but are actually fermenting it all to fatty acids and like the naked mole rat are physiologically insulin resistant.

What do I eat (2014)?

It’s been a while, I do have a back log of posts waiting to be finished on mitochondrial uncoupling, hormones, ketones, and diatomic hydrogen, they are all separate posts but they fit together.

Work has been busy, so has life, but thinking about what I think about never stops. And I constantly flagellate myself for not keeping up with writing.

Since I have limited time I thought I’d write a bit about what I eat for those that are curious or confused by some previous posts.

In the mornings I usually have about half a pint of cream (which is pastured), there is coffee somewhere in there (a French roast made in the press). I do drink this throughout the morning, it’s not a contest.

For lunch or somewhere around that time I like cream cheese which is imported from France (hat tip to Whole Foods for managing that one), cream cheese is made from cream not milk, so it has tiny amounts of protein and although the label says there are no carbohydrates I bet there are a few molecules in there somewhere.

After lunch I usually have a cup or two of Bulgarian yogurt which is made from whole milk.  I sometimes have that in the morning as well. It’s pretty common for me to go through at least 3 cups of that a day.

Dinner is usually beef (which is pastured and I go very very out of my way to get it from a specific farmer… the fat still tastes sweet… that’s fresh), although I don’t always eat meat every day, when I do I make up for it. I like beef short ribs, beef shank, marrow bones, oxtails, and that sort of thing. Love roasts. I don’t know how much beef I eat but probably approaching 1 pound or so on average which sometimes includes the weight of the bones other times not.

Somewhere between lunch and dinner I usually work in the other half pint of cream, and in the evenings I’ve been known to have up to 2 quarts of milk accompanied with cream cheese. But that is rare.

I rarely use anything more but salt, and even then I usually don’t use it, I salt to taste when needed. Needless to say I have no problem with using spices and the like and/or veggies when I have a hankering for them. My taste buds are unspoiled I guess.

I do lift heavy weights every single day, not for health reasons but because I enjoy that type of thing, much like the other things I do in my life.

That’s about it. Some days I have only cream and yogurt, some days I’m not hungry in the morning and don’t eat till dinner, you get the picture.

Edward

Oh, I do have butter milk on occasion or mix it with my milk, I like the sour taste.

Clariece

I once had a white rabbit named Clariece. Her and my Turkish Van cat, Chuck, used to sit and look at each other for long periods of time. They shared the litter box. If you know anything about rabbits, you know that sweet potatoes and other starchy things can be lethal.

Rabbits are herbivores.

Rabbits use hindgut fermentation.

One day many moons ago when sweet potato was something I ingested quite frequently because it tasted good, some fresh sweet potato fresh from the market was left on a low shelf (not by me) within a rabbits paw reach of my fluffy white rabbit Clariece.

A day later I noticed Clariece looked puffy. Very puffy. And quite hard. Then I noticed she was sitting very still for long periods of time in the corner. Something was wrong.

Later that day when I went to cook sweet potato I noticed that half of one was gone.

My forensic investigation of the sweet potato revealed fluffy white rabbit teeth marks.

I continued to watch over her and tried to keep her comfortable hoping for the best. Her last hops were her hoping over to the litter box climbing inside to take her last breath of cat piss.

I’m sure the sweet potatoes tasted quite good to her.

Liver tastes like shit.

Energy and Structure: What can RQ tell us?

I wanted to do a short post quickly before I start packing my apartment to move early this week. Here I just want to look at RQ as a measurement and what it can tell us. I will write more about RMR and how it relates to RQ including different physiological states that influence RQ such as birth, what happens to RQ at the start of breast feeding, how thyroid hormones effect RQ, etc. once I get into my new apartment.

There can be a problem when reading papers as to what it exactly means to have a “high metabolism”. The phrase is loosely defined. But some people, including Dr. Peat, define the strength of the metabolism based on the RQ (respiratory quotient). The RQ is essentially the ratio of carbon dioxide eliminated to oxygen consumed.

Roughly:

RQ = C02 eliminated / O2 consumed

A RQ closer to 1 typically means more carbohydrate is being burned and a value closer to 0.7 typically means fat is being burned.

For some reason there is the idea that a high RQ closer to 1 is the same thing as a “high metabolism”. I don’t really know how RQ became associated with the rate of the metabolism. RQ tells you essentially what fuel you are burning, nothing about the rate of your metabolism.

“On a normal diet, his weight was 152 pounds, and his metabolic rate was from 9% to 12% below normal, but after six months on the diet it had increased to 2% below normal. After three months on the sugar and milk diet, his weight leveled off at 138 pounds. After being on the diet, when he ate 2000 calories of sugar and milk within two hours, his respiratory quotient would exceed 1.0, but on his normal diet his maximum respiratory quotient following those foods was less than 1.0.

The effect of diabetes is to keep the respiratory quotient low, since a respiratory quotient of one corresponds to the oxidation of pure carbohydrate, and extreme diabetics oxidize fat in preference to carbohydrate, and may have a quotient just a little above 0.7.” ~Dr. Peat

“His respiratory quotient increased (producing more carbon dioxide), as well as his rate of resting metabolism.” ~Dr. Peat

“Maintaining a high rate of oxidative metabolism, without calorie restriction, retards the accumulation of PUFA, and a high metabolic rate is associated with longevity. An adequate amount of sugar maintains both a high rate of metabolism, and a high respiratory quotient, i.e., high production of carbon dioxide.” ~Dr. Peat

“At high altitude, or when taking a carbonic anhydrase inhibitor, there is more carbon dioxide in the blood, and the serum phosphate is lower; sucrose and fructose increase the respiratory quotient and carbon dioxide production, and this is probably a factor in lowering the serum phosphate.” ~Dr. Peat

Needless to say, the only point with which I agree with from above is that carbohydrate increases RQ and fructose is effective at the task. The literature supports that.

It seems that as we age RQ increases and if you believe that a higher RQ is a measure of the rate of metabolism this can lead to some paradoxical conclusions. If that is what you think, you don’t have to do anything, your RQ will increase without any dietary intervention.

In obesity and diabetes it is observed that RQs tend to be higher (more towards 1). Aging, disease, and other metabolic derangements at the end of the day all basically stem from hypoxia (Douglas & Haddad, 2008).

“Similarly, individuals with a high 24-hour respiratory quotient (RQ) are more likely to gain weight than those with a low RQ.” (Ravussin, 1995)

“Over a 7-year period, mean unadjusted and adjusted 24-hour RQ increased (p < 0.01). Cross-sectional data analysis showed that both the unadjusted (r = 0.19, p < 0.03) and adjusted (r = 0.19, p < 0.03) 24-hour RQ correlated with increasing age while adjusted BMR (r = -0.21, p < 0.02) correlated inversely with age.” (Rising, Tataranni, Snitker, & Ravussin, 1996)

“Subjects with higher 24-h RQ (90th percentile) independent of 24-h energy expenditure were at 2.5 times higher risk of gaining greater than or equal to 5 kg body weight than those with lower 24-h RQ (10th percentile).” (Zurlo et al., 1990)

“In contrast obese patients who succeeded to retain the weight loss achieved initially by the VLCD at 2-yr follow-up (weight losers) or those who did not exhibit weight fluctuations (weight noncyclers) were characterized by a significantly lower RQ.” (Hainer, Kunesova, & Parizkova, 1999)

“High nonsleeping RQ (NSRQ) predicted 2-year change in FM independently of energy balance, circulating insulin, and insulin sensitivity. This observation suggests that low postprandial fat oxidation may uniquely predispose obesity-prone individuals to accrual of adipose tissue.” (Ellis, Hyatt, Hunter, & Gower, 2010)

cho thyroidThe real world is a fascinating place.

Now a high RQ is not always associated with weight gain, this is why RQ really should not be associated with the rate of metabolism. If you are into calorie counting, you can have a high RQ on a high carbohydrate diet without gaining weight. But DNL is going to be very active. You’ll be burning fat just as quickly as you make it. Your triglycerides will probably increase, but they might not if you are taking thyroid. which is going to enhance fatty acid oxidation.

Aside: Thyroid hormone itself stimulates DNL. DNL is reduced in hypothyroidism and treatment with T3 increases DNL.

T3 also decreases the RQ (Barbe et al., 2001).

Of course long term you are going to run into a lot of side effects as DNL will eventually not be able to supply the demand T3 places on fatty acid oxidation. This is speculative, but I think a reasonable partial explanation for why a lot of people on a low-fat-high-carbohydrate-diet taking thyroid probably feel better when they eat more saturated fat.

The entrenched individual

“When something out of the ordinary happens, it is ridiculous to say that it is a mystery or a portent of something to come. Eclipses of the sun and moon, comets, clouds that flutter like flags, snow in the fifth month, lightning in the twelfth month, and so on, are all things that occur every fifty or one hundred years. They occur according to the evolution of Yin and Yang. The fact that the sun rises in the east and sets in the west would be a mystery, too, if it were not an everyday occurrence. It is not dissimilar. Furthermore, the fact that something bad always happens in the world when strange phenomena occur is due to people seeing something like fluttering clouds and thinking that something is going to happen. The mystery is created in their minds, and by waiting for the disaster, it is from their very minds that it occurs. The occurrence of mysteries is always by word of mouth.” ~Yamamoto Tsunetomo

It’s interesting how words, phrases, ideas, and behavior go through multiple stages of metamorphosis within the context of a culture, subculture, and individual level.

Metamorphosis in insects ends with a self-sufficient organism able to consume energy and reproduce. After reproduction, the insect soon dies leaving it’s offspring to fulfill both an environmental and reproductive purpose. But metamorphosis is a linear process; there is a beginning and an end. What emerges from the cocoon is something refined for a specific purpose. Words, phrases, ideas, and behavior tend to have a linear development, but follow circular patterns of refinement until their meaning becomes either precise or meaningless.

Nutrition is difficult to define. For some it is lists of safe foods. For others it’s all about having energy to do what one wants to do in life for as long as possible. And there are a majority of people who don’t concern themselves with defining it.

It is the commercialization of nutrition and my interest in psychology that eventually interested me (besides my own self-experimentation and observations) in the psychological impact of nutrition, pre- and post-, on behavior.

I have found, in observation, that an idea a culture is attempting to define follows a process with patterns that can be developed into behavioral frameworks, which predicts the refinement process. It is the process of refining the definition of an idea that isolates or unites different groups of people. This process is similar to Max Weber’s idea of “rationalization” in the context of religion.

One cannot be down on people who are led to and fro by different dietary paradigms. This process is a consequence of rationalization driven by the unconscious. Likewise, one cannot be down on an entire culture defined by its government officials or religion. Its nature is what has allowed us to survive without the interconnection that now defines our world. Developed personality and individuality in the Jungian sense is a unique occurrence.

In the modern world there is less need for reliance on others. But there is still a need for passing on of knowledge, tradition, and wisdom, suitable for survival, social interactions, and going about daily activities. Science and the Internet are impacting cultural instinct, traditions, and wisdom through exposure. I view this exposure neutrally. Complete confidence on what others deem as fact is often a mistake just as being overly self-reliant and reinventing the wheel again is inefficient. There is a cautious balance to be struck, especially in a time when there is a shift in consciousness and the process of cultural diffusion is active.

An intelligent, thinking, and reasoning being must strike a balance between the two. It is this balancing act that allows cultural evolution to occur and new paradigms to develop which will be tested by successive generations. What works stays, what doesn’t work leaves; better ways of doing things slowly filter out older ways of doing things. New ways of thinking philosophize old traditions and religions. For example: Thomas Aquinas, applying Greek philosophy to biblical texts, or Martin Luther, nailing his grievances to the Catholic cathedral door.

These events happen when there is a shift in unconsciousness. And what follows is a revolution in cultural knowledge to try and rationalize why we did things the way we did in the past and why it is justified to change things for the future. Radicals entrenched in their beliefs usually, but not always, die in these shifts of thinking; literally or by sacrificing the personality. Being a martyr for a particular paradigm has never been a personally natural inclination. When the individual is cornered and experience is conflicted with lacquered beliefs, the individual is faced with options of entrenching themselves behind belief or taking steps to evolve in another direction. It is the collateral damage of opposing extreme views in groups of people that often drive cultural evolution. At some point we must put aside belief and continue moving forward. A fight to the death is not a viable option except for the delusional.

“We should not let ourselves be burnt for our opinions: we are not that sure of them. But perhaps for this: that we may have and change our opinions.” ~Nietzsche

What is difficult for the entrenched individual is not the new shift, but the shift that points to years or a life wasted and genuine interests forsaken. There is a saying: “You can’t teach an old dog new tricks.” Few people are so downright stubborn. But these defining qualities are common enough that most of us are familiar with these individuals.

Entrenching is not the new idea but rather the aversion to self-confessing an error approaching things in a new way.  The conflict does not arise out of the new idea but arises out of the individual. These individuals place too much power in words and ideas. These people are the real dangers in society—not the originators of new ideas. It takes much more than an individual to do anything with a dangerous idea, just as it takes much more than an individual to do something with a useful idea. Ideas have to be stated and different people must implement them before they can become a useful or dangerous reality.

Despite modern man’s large brain, the rational portion seems atrophied in most. This allows erroneous thought to pervade in popular culture and society, causing harm. Capitalistic,  mechanistic, and authoritarian thinking makes this easy to do.

Some ideas tend to have cyclical natures occurring and reoccurring throughout history, often shifted or changed slightly but still keeping their original essence or philosophy. Observations have personally demonstrated that ideas are cyclical simply because what is current is not satisfying and causes gas and bloating. When enough people smell the stink they become uneasy and start to look for new solutions.

People try old ideas, not simply for the sake of the new, but for the promise of something better (or curing chronic boredom).

Old ideas come and go and are cyclical for many reasons. One reason assumes there is validity to the idea, yet for whatever reason remains underdeveloped in that period of time. There have been plenty of ideas left undeveloped because of a requirement for a different field of science. Later, some of these ideas ended up being game changers in the modern era.

Another reason is simply that the idea was not valid. When people do try old, invalid ideas in their life, you will often find that these people are constantly trying to justify the validity of their dug up treasure. Foolishness is the virtue of the wise.

There is nothing vain about exploring history through a modern perspective and trying old approaches when modern and fringe approaches fail. Trying is one thing. Trying is not miserably “riding it out”. Loosely illustrated, trying means taking an interest in the cello and with every passing lesson there is improvement in both technical aspects and style; persistently trying means taking up the cello and despite best efforts never being able to complete the first lesson, despite trying for several weeks, months, or years. For those, the cello, despite intense interest, will always remain just an interest.

When something does not work for you, be bold, ask questions and seek answers.

“Possessing opinions is like possessing fish, assuming one has a fish pond.  One has to go fishing and needs some luck—then one has one’s own fish, one’s own opinions.  I am speaking of live opinions, of live fish.  Others are satisfied if they own a cabinet of fossils—and in their heads, convictions.” ~Nietzsche

Some thoughts on aspirin

Filip left a comment asking about aspirin, this was another one of those comments turned into post type deals.

So speaking of aspirin. There are some dots to connect here, and definitely some different trains of thought that you can ride, but have a look at the following articles and follow the paper trail.

First this:

Paterson, J. R., Baxter, G., Dreyer, J. S., Halket, J. M., Flynn, R., & Lawrence, J. R. (2008). Salicylic acid sans aspirin in animals and man: persistence in fasting and biosynthesis from benzoic acid. Journal of Agricultural and Food Chemistry, 56(24), 11648–52. doi:10.1021/jf800974z

“To examine the possibility of a gastrointestinal bacterial source for SA, two small groups of germ-free mice were assayed for SA. The pooled serum from six mice treated with neomycin, 100 mg/kg/day, for 4 days before sacrifice had a slightly higher concentration of SA in serum (0.309 μmol/L) than the pooled serum sample from six untreated animals (0.268 μmol/L). Another germ-free animal model studied was the Sprague−Dawley rat delivered by caesarean section, reared in a sterile environment, and fed sterilized food. A group of eight such germ-free animals had a pooled serum SA level of 0.166 μmol/L, approximately 2.5 times greater than the pooled serum salicylic acid level of 0.069 μmol/L from a group of control animals. The net effect of minimizing or eliminating a contribution from colonic bacteria in these animal models was therefore enhancement of serum SA levels in the host animal.”

“Results of SA levels in a large variety of animals showed that those species regarded as primarily carnivorous had levels comparable to those measured in herbivores. Some bacteria, notably mycobacterial, yersinia, and pseudomonas species, synthesize SA to enhance iron chelation, so there was a possibility that gut, particularly colonic, bacteria might be the source of SA not readily explicable by lack of dietary exposure. However, preliminary study of two germ-free animal models reported here showed the net effect of minimizing or eliminating a contribution from colonic bacteria was, in fact, an increase in serum SA levels.”

Then there is this interesting little snippet:

A review of the literature by Heiby cites an interesting experiment on rat that perhaps shed some light on the risk of stomach bleeding. Aspirin was far more toxic to rats fed a high carbohydrate diet than it was to rats fed a high protein diet. A deficiency of magnesium increased this toxicity, especially in pregnant animals. Gastric ulceration in non-pregnant rats was very severe on the high carbohydrate diet (14, p. 255). On the basis of these animal studies, it is interesting to speculate that the apparent increase over the last half-century in the risk of stomach bleeding due to aspirin use may be the result of the large increase in dietary carbohydrate during the same period.

I originally came across that here. But as it is written there, there are differences in the in-text citations and I was not able to track down a paper to verify that observation.

George has some thoughts on aspirin as well.

And Peter mentions this (there is also a bit on coconut oil in the following paragraph if you follow the link, for the few that asked about that):

Anyone reading Chris or Emma’s blogs will realise that aspirin, and possibly other related salycilates from plants, cause the pancreas the secrete extra insulin. Avoid. Gluten and wheat germ agglutinin (both from wheat, barley and rye) are (or contain) insulin mimetics, avoid. Casein stimulates insulin secretion, avoid. Pharmaceutical NSAID probably do the same as salycilates, avoid if possible.

O.k. Now for some of my thoughts.

As for daily use, I don’t know. In general, I like things that uncouple the mitochondria. However, to speculate, there is a difference between an energy substrate that uncouples mitochondria and a compound that uncouples mitochondria. I think that the latter can deplete ATP to an extent that is undesirable (which would be dose dependent)., but I can also think of some situations where that type of uncoupling would confer some desired effects. In my endotoxin and fructose post I talked about depleted ATP impacting tight-junction (occluding junctions or zonulae occludentes) integrity. Which makes this interesting. Whereas some saturated fat (e.g. palmitic acid) which also uncouples the mitochondria maintains tight-junction integrity.

Speculating some more, a lot of people get nosebleeds from aspirin use. When you get a nose bleed, you notice it, blood dripping out of your nose, that to me is like a rupture. You don’t notice one or two blood cells on your upper lip, you notice a good amount of blood coming out. That is a tremendous failure in the integrity of the tight-junctions in capillaries. Now imagine consuming some fructose (which is depleting ATP too and probably weakening tight-junctions). It is hardening your arteries and when they are nice and calcified, lets say you take some aspirin and one of your calcified capillaries “fractures”, but see now your blood is thin and blood comes spouting out. Sounds quite like an aneurysm.

Because fructose isn’t going to calcify your vascular system overnight, I’m sure little microscopic breaks happen here and there in the tight-junctions which get clotted. Imagine a wooden handrail that thousands of people have run their hands across, some parts keep their shine, other parts chip off and loose their luster. It’s a handrail with character. Or have you ever filled a balloon up and over time you notice certain parts of it are thin and thick as the air diffuses out? Between the clotting and inflammation, I’d say damaged parts of the vascular system might swell much like the thick and thin sections of a balloon under uneven pressure caused by variations in thinness and thickness of vascular/capillary walls. Have you ever untied a worn out balloon that has been sitting in the sun and tried to blow it back up again? It’s never quite the same, and I would imagine the brittleness from the deteriorated rubber would be an interesting way to think about the pathophysiology of a nose bleed or aneurysm. It just fractures at a weak point and pops if you blow it up big enough e.g. a sudden increase in heart rate.

O.k. now this brings me back to aspirin. Sometimes when I’m writing with an old fashioned pencil the tip breaks off in a way where you can kind of fit it back into the pencil and continue writing with it. That of course is not very versatile because you almost always have to write with less pressure and kind of turn the angle of the pencil where the lead broke to keep the bit of lead in. If you have some clots just waiting to break off it would make sense to lower the viscosity of your blood so as not to disturb them. I would say aspirin would be pretty useful for that.

Anyway, I think aspirin might be useful to solve some acute symptoms. And hey, maybe a low-dose aspirin is legit. But don’t forget about the first paper. Like I said, there are a few different trains of thought to ride. Preventing an “aspirin deficiency” would be a better bet. At least that is what I think.

Fructose and Endotoxin

“What was it Oscar Wilde said? ‘The well-bred contradict other people, the wise contradict themselves.’ If you have insight into a body of knowledge, you are going to discover science that contradicts your view. You either modify your model, which if it is sound will survive and benefit from such adjustments, or you put on well-bred airs.

This is the distinction between science, where you are interested in learning new things, and wise enough to contradict yourself as a result, and dogma, accepting which will force you to contradict others (or indeed censor them) unless they agree with you.” ~George Henderson

There was a time when I had a fairly liberal view on the issue of sugar. Sugar resurged when people seemed to be having all kinds of problems with low carbohydrate diets. And to a great many people sugar seemed to resolve some issues. I cannot debate that. I also cannot vouch for the pros or cons of long-term use of liberal amounts of sugar in other people. Some people claim it has helped them to their surprise, others have claimed it has destroyed their health. It is a paradox.

However, I can vouch for myself and a few other people that sugar without a doubt  had an absolute negative impact on my/their health in the long-term. Sugar can be useful in some instances e.g. emergency medicine. No doubt that in a calorically malnourished individual sugar can have seemingly positive effects. Despite that, I think there are better and safer ways, lest you want to risk re-feeding syndrome.

But here I want to discuss something briefly that I’ve observed. A quick browse around Ray Peat centered forums and you find that a lot of people have digestive issues. They eat sugar, and if they only eat sugar they seem to do o.k. for a while until they start to introduce new food. Foods that I would consider quite normal. I’m sure there are people who claim that sugar improved their digestion. Fair enough.

I’ve always found the issue of endotoxin intriguing especially when it comes to “leaky gut”. The entire issue of endotoxin is an interesting one. In the end we probably die from sepsis and hypoxia, if something else doesn’t get you first. Yet endotoxin seems to play an important role in immune health. It’s the kind of thing where you want to be in control of it. You don’t want none and you don’t want too much for too long. And of course somewhere in one on my posts I’m quite sure I linked to a study discussing the possibility of a hormonal role for endotoxin.

Endotoxin is not really something that I worry about. Saturated fat is quite good at keeping the tight junctions healthy and functioning. There are a few people around the web who have discussed this. So I’m not going to rehash.

Anyway, there are people whose digestive problems get worse when they eat sugar. There are host of reasons and angles really to look at this. But I want to focus on the effect of fructose. Fructose is quite effective at depleting ATP (Mayes, 1993). That is not a good thing considering that when ATP is depleted, the cells will enter a stressed state. No ATP=comprised cell function. This would have a ripple effect throughout an organism long-term causing all kinds of systematic symptoms which essentially stems from inefficient or inhibited respiration.

I would imagine that depleted ATP would compromise tight junction function. Something which would probably lead to endotoxin “leaking” everywhere. So here you have a situation where when tight junction function is compromised, you literally have LPS poisoning tissue. On the other side of the coin you also have the effect where fructose seems to “tighten” capillaries (Chakir, 1998; Yuan et al., 2007). Some people have viewed this as a good thing. I view it negatively. I want my capillaries to maintain their elasticity and permeability. I want my tissues to always be able to have efficient gas exchange and waste removal. One can easily see how tightened capillaries can cause hypoxia in peripheral tissues. Which of course is something we see in diabetics, not to mention hypertension. As well, I would imagine this could increase systematically serum levels of endotoxin.

You want to maintain the elasticity of the vascular system. You want it to be able to “breathe” properly. One of the sites of endotoxin detoxification is in the lungs. If your capillaries are hardened, detoxification of endotoxin is compromised. Once again, a feature of diabetes induced by fructose is endotoxemia (Kavanagh et al., 2013).

Another feature of fructose feeding is also hyperinsulinemia/insulin resistence (of the wrong sort) (Chakir, 1998). Fructose probably hardens the arteries. If you eat sugar (which is fructose and glucose), fructose will eventually have the effect of hardening the arteries, thus blocking insulin from transporting the glucose bit to where it belongs.

I would say for me personally it is impossible to maintain a liberal disposition with fructose, I can definitely see some cases where small amounts of it could have a potential hormetic effect. But in the long term I think liberal use of fructose is unwise.

Aside: It is interesting to note that some lactic acid bacteria strains protect from endotoxin (Nanji, Khettry, & Sadrzadeh, 1994).

Impaired insulin transcapillary transport and the subsequent decrease in insulin delivery to target organs have been suggested to play a role in insulin resistance. These defects were studied in fructose-fed rats, an animal model with insulin resistance. For this study, male Sprague-Dawley rats were fed with either a 60% fructose enriched (F) or a standard chow diet (N) for a total of 2, 4, or 8 weeks. Capillary permeability to albumin was assessed at the end of each dietary period by quantifying the extravasation of albumin-bound Evans blue (EB) dye in different organs. Unanesthetized animals were injected with Evans blue dye (20 mg/kg) in the caudal vein 10 min before being killed and EB dye was extracted by formamide from selected organs collected after exsanguination. As expected, rats had an increase in blood pressure upon feeding with fructose at 4 and 8 weeks (F, 149 +/- 3 mm Hg; N, 139 +/- 3 mm Hg; P < .05). Using this technique, we showed a 56% and a 51% reduction in capillary permeability in skeletal muscles at 4 and 8 weeks of fructose feeding, respectively (4 weeks: N, 44.5 +/- 5.0 microg/g of dry tissue; F, 19.8 +/- 4.2 microg/g of dry tissue; P < .01 and 8 weeks: N, 23.3 +/- 3.7 microg/g of dry tissue; F, 11.3 +/- 4.0 microg/g of dry tissue; P < .05). Similar changes were observed at 4 weeks in the thoracic aorta (N, 82.8 +/- 8.8 microg/g of dry tissue; F, 53.0 +/- 5.1 microg/g of dry tissue; P < .02) and skin (N, 36.0 +/- 5.3 microg of dry tissue; F, 15.0 +/- 2.3 microg/g of dry tissue; P < .02) and at 8 weeks in the liver (N, 107.5 +/- 4.3 microg/g of dry tissue; F, 80.9 +/- 3.2 microg/g of dry tissue; P < .01). In conclusion, fructose feeding is accompanied by a significant and selective reduction of Evans blue leakage primarily in skeletal muscle and liver, and transiently in the skin and aorta, consistent with a role for decreased tissue insulin delivery in insulin resistance.

BACKGROUND: Controversy exists regarding the causative role of dietary fructose in obesity and fatty liver diseases. Clinical trials have indicated that negative health consequences may occur only when fructose is consumed within excess calories. Animal studies have suggested that fructose impairs intestinal integrity and leads to hepatic steatosis (HS). OBJECTIVES: We assessed nonhuman primates after chronic ad libitum and short-term calorically controlled consumption of a high-fructose (HFr), low-fat diet (24% of calories). Microbial translocation (MT), microbiome, and metabolic health indexes were evaluated. DESIGN: Seventeen monkeys fed 0.3–7 y of an HFr ad libitum diet were compared with 10 monkeys fed a low-fructose, low-fat diet (control). Ten middle-aged, weight-stable, fructose-naive monkeys were stratified into HFr and control groups fed for 6 wk at caloric amounts required to maintain weight stability. Metabolic endpoints, feces, liver, small and large intestinal biopsies, and portal blood samples were collected. RESULTS: Monkeys allowed ad libitum HFr developed HS in contrast to the control diet, and the extent of ectopic fat was related to the duration of feeding. Diabetes incidence also increased. Monkeys that consumed calorically controlled HFr showed significant increases in biomarkers of liver damage, endotoxemia, and MT indexes and a trend for greater hepatitis that was related to MT; however, HS did not develop. CONCLUSIONS: Even in the absence of weight gain, fructose rapidly causes liver damage that we suggest is secondary to endotoxemia and MT. HS relates to the duration of fructose consumption and total calories consumed. These data support fructose inducing both MT and ectopic fat deposition in primates.

Most of the metabolic effects of fructose are due to its rapid utilization by the liver and it by-passing the phosphofructokinase regulatory step in glycolysis, leading to far reaching consequences to carbohydrate and lipid metabolism. These consequences include immediate hepatic increases in pyruvate and lactate production, activation of pyruvate dehydrogenase, and a shift in balance from oxidation to esterification of nonesterified fatty acids, resulting in increased secretion of very-low-density-lipoprotein (VLDL). These effects are augmented by long-term absorption of fructose, which causes enzyme adaptations that increase lipogenesis and VLDL secretion, leading to triglyceridemia, decreased glucose tolerance, and hyperinsulinemia. Acute loading of the liver with fructose causes sequestration of inorganic phosphate in fructose-1-phosphate and diminished ATP synthesis. Consequently, the inhibition by ATP of the enzymes of adenine nucleotide degradation is removed and uric acid formation accelerates with consequent hyperuricemia. These effects are of particular significance to potentially hypertriglyceridemic or hyperuricemic individuals.

We have previously shown a relationship between plasma endotoxin levels and severity of alcoholic liver injury in the intragastric feeding rat model. We attempted to reduce both circulating endotoxin and liver injury in this model by administering a lactobacillus strain (species GG) which survives for prolonged periods in the gastrointestinal tract. Male Wistar rats were fed ethanol and liquid diet containing corn oil (CO+E). Another group of animals (CO+E+L) received the diet containing ethanol plus a daily bolus of lactobacilli GG concentrate (10(10) CFU). All animals were sacrificed after one month. All animals had plasma endotoxin measurements and evaluation of severity of pathologic changes in the liver. The weight gain and blood alcohol levels were similar in both groups. The mean +/- SE of the pathology score was significantly higher (3.4 +/- 0.85) in the CO+E group compared to the CO+E+L group (0.5 +/- 0.3, P < 0.01). The virtual absence of pathologic changes in the latter group was accompanied by significantly lower endotoxin levels (8.4 +/- 2.9 pg/ml in CO+E+L group vs 48.3 +/- 7.8 pg/ml in CO+E group, P < 0.01). Feeding of strains of lactobacilli that survive in the gastrointestinal tract reduces endotoxemia and alcohol-induced liver injury in the rat. Lactobacillus species GG provides a potential nontoxic form of therapy for both endotoxemia and alcoholic liver disease.

Microvascular barrier injury has been implicated in the initiation and progress of end organ complications of diabetic mellitus. Plasma leakage and fluid retention are seen in various tissues of diabetic patients or animals at the early stages of the disease before structural microangiopathy can be detected. Clinical and experimental evidence suggests that hyperglycemia, often accompanied with insulin deficiency or insulin resistance, causes impaired autoregulation and increased permeability in microvessels. Multiple molecular pathways have been identified as contributors to the altered fluid homeostasis, including increased polyol flux that promotes oxidative stress, advanced glycation that leads to carbonyl stress, and excessive glucose metabolism that results in protein kinase C activation. These abnormal metabolic activities are associated with the production of pro-inflammatory cytokines and growth factors, which can stimulate an array of signaling reactions and structural changes at the endothelial barrier and ultimately cause microvascular leakage. Interventions that manipulate these metabolic and inflammatory pathways have demonstrated efficacy in delaying the progress of diabetic microvascular complications; however, their direct effects and mechanisms of action on the microcirculation remain elusive. A deeper understanding of the molecular basis of diabetes-induced endothelial barrier dysfunction will provide a framework for the development of new therapeutic targets to treat this chronic and debilitating disease process.

Calcium to phosphorus ratio

“Of the eighteen elements of which the human body is composed, all of which are presumably essential, several are needed in very small quantities. A few are required in liberal quantities. The normal adult needs to receive from the foods eaten one-half to one gram of calcium or lime per day. Few people receive more than one-half of the minerals present in the food. The requirements of phosphorus are approximately twice this amount. Of iron we need from one-seventh to one-third of a gram per day. Smaller amounts than these are required of several other elements. In order to utilize these minerals, and to build and maintain the functions of various organs, definite quantities of various organic catalysts which act as activating substances are needed. These include the known and unknown vitamins.”

Interesting that Price observed calcium to phosphorus ratio of 1:2 in healthy traditional tribes. Undoubtedly it would be hard to flip this ratio unless you were a dairy herding tribe.

What to eat?

7-SAV137-perfectroast-400x330One of things that many find difficult with Dr. Peat is that you can read pages and pages of his ideas and at the end of it you basically are left guessing what it is that you are going to eat. Never mind the inaccuracies. People like Danny Roddy and forums like Peatarian, Ray Peat forum and Co. have attempted to make recommendations through their interpretations. There are some interesting graphics and the sort all around the web, based on those ideas.

I’m all for theory and all that jazz and cool diagrams and inverted pyramids, but really, like I have written before in various places, most people are interested in nutrition because they are sick, not because they want to become nutritionists. They just want to get better and get on with their lives. In that sense I believe in something practical.

My unimpressive advice is to source your diet from cattle. This means eating things like steaks, roasted bones (the marrow), liver, oxtails, suet, tallow, (insert whatever part of the cow you fancy here). Those things are good to eat cooked however you like. This also means that all dairy such as cheese (fresh or aged), yogurt of any type e.g. Kefir, FAGE, (insert any type of plain full fat yogurt here), sour cream, whole milk, cream, half and half, butter, etc. Although I’m using the cow here, as a specific example, really, any ruminant animal and their milk and milk products are good to eat e.g. sheep, bison, goat, etc.

Eat till you are full and drink as much milk as you like. Suet is useful for a lot of things, a lot of people like to use coconut oil, but suet is cheaper in most cases and I think it is better to use along with butter. I don’t recommend coconut oil.

There is no doubt that you can carve out a fine existence living off of those things.

Things to minimize: starch and sugar. Non-starchy vegetables are a fine and welcome addition to any stew as well as whatever spices and seasonings you like. For example, carrots, celery, leek, garlic, onion, (those are just random vegetables, no, there is no reason for me mentioning them, and no they do not hold magical power), all of these things you will find in hearty stews, as well as seasonings for your meat which adds wonderful flavor. Boiled greens are also good to eat, they can be boiled in water with a pinch of salt, cooked until they have a pleasant taste, drained, and then covered with a bit of cream or butter.

The major source of CHO will be coming from dairy. There is no magic number of carbohydrates I recommend I just recommend that you drink a fair amount of milk something like 1.5-2+ quarts per day. Lactose in milk is sufficient to supply the amount of glucose you need. Galactose is also unique in that it enhances OXPHOS and reverses the inhibitive effect on respiration caused by glucose and fructose (Aguer et al., 2011; Chico, Olavarría, & de Castro, 1978; Diaz-Ruiz, Rigoulet, & Devin, 2011; Dott, Mistry, Wright, Cain, & Herbert, 2014; Marroquin, Hynes, Dykens, Jamieson, & Will, 2007; Sussman, Erecińska, & Wilson, 1980).

Eat till you feel satisfied, eat when you are hungry, and don’t count anything, don’t worry about phosphate (Hettleman, Sabina, Drezner, Holmes, & Swain, 1983), don’t worry about trying to get a certain number of this or that. Focus on getting creative with the infinite amount of dishes you can prepare with these rich ingredients.

Coffee, chocolate, beer, wine, and tea, are always welcome, and I think nicotine is useful.

Salt your food to taste (MENEELY, TUCKER, & DARBY, 1952; MENEELY, TUCKER, DARBY, & AUERBACH, 1953).

BACKGROUND: Human primary myotubes are highly glycolytic when cultured in high glucose medium rendering it difficult to study mitochondrial dysfunction. Galactose is known to enhance mitochondrial metabolism and could be an excellent model to study mitochondrial dysfunction in human primary myotubes. The aim of the present study was to 1) characterize the effect of differentiating healthy human myoblasts in galactose on oxidative metabolism and 2) determine whether galactose can pinpoint a mitochondrial malfunction in post-diabetic myotubes. METHODOLOGY/PRINCIPAL FINDINGS: Oxygen consumption rate (OCR), lactate levels, mitochondrial content, citrate synthase and cytochrome C oxidase activities, and AMPK phosphorylation were determined in healthy myotubes differentiated in different sources/concentrations of carbohydrates: 25 mM glucose (high glucose (HG)), 5 mM glucose (low glucose (LG)) or 10 mM galactose (GAL). Effect of carbohydrates on OCR was also determined in myotubes derived from post-diabetic patients and matched obese non-diabetic subjects. OCR was significantly increased whereas anaerobic glycolysis was significantly decreased in GAL myotubes compared to LG or HG myotubes. This increased OCR in GAL myotubes occurred in conjunction with increased cytochrome C oxidase activity and expression, as well as increased AMPK phosphorylation. OCR of post-diabetic myotubes was not different than that of obese non-diabetic myotubes when differentiated in LG or HG. However, whereas GAL increased OCR in obese non-diabetic myotubes, it did not affect OCR in post-diabetic myotubes, leading to a significant difference in OCR between groups. The lack of an increase in OCR in post-diabetic myotubes differentiated in GAL was in relation with unaltered cytochrome C oxidase activity levels or AMPK phosphorylation. CONCLUSIONS/SIGNIFICANCE: Our results indicate that differentiating human primary myoblasts in GAL enhances aerobic metabolism. Because this cell culture model elicited an abnormal response in cells from post-diabetic patients, it may be useful in further studies of the molecular mechanisms of mitochondrial dysfunction.

During the last decades a considerable amount of research has been focused on cancer. Recently, tumor cell metabolism has been considered as a possible target for cancer therapy. It is widely accepted that tumors display enhanced glycolytic activity and impaired oxidative phosphorylation (Warburg effect). Therefore, it seems reasonable that disruption of glycolysis might be a promising candidate for specific anti-cancer therapy. Nevertheless, the concept of aerobic glycolysis as the paradigm of tumor cell metabolism has been challenged, as some tumor cells exhibit high rates of oxidative phosphorylation. Mitochondrial physiology in cancer cells is linked to the Warburg effect. Besides, its central role in apoptosis makes this organelle a promising “dual hit target” to selectively eliminate tumor cells. From a metabolic point of view, the fermenting yeast Saccharomyces cerevisiae and tumor cells share several features. In this paper we will review these common metabolic properties as well as the possible origins of the Crabtree and Warburg effects.

Mitochondrial toxicity is increasingly being implicated as a contributing factor to many xenobiotic-induced organ toxicities, including skeletal muscle toxicity. This has necessitated the need for predictive in vitro models that are able to sensitively detect mitochondrial toxicity of chemical entities early in the research and development process. One such cell model involves substituting galactose for glucose in the culture media. Since cells cultured in galactose are unable to generate sufficient ATP from glycolysis they are forced to rely on mitochondrial oxidative phosphorylation for ATP generation and consequently are more sensitive to mitochondrial perturbation than cells grown in glucose. The aim of this study was to characterise cellular growth, bioenergetics and mitochondrial toxicity of the L6 rat skeletal muscle cell line cultured in either high glucose or galactose media. L6 myoblasts proliferated more slowly when cultured in galactose media, although they maintained similar levels of ATP. Galactose cultured L6 cells were significantly more sensitive to classical mitochondrial toxicants than glucose-cultured cells, confirming the cells had adapted to galactose media. Analysis of bioenergetic function with the XF Seahorse extracellular flux analyser demonstrated that oxygen consumption rate (OCR) was significantly increased whereas extracellular acidification rate (ECAR), a measure of glycolysis, was decreased in cells grown in galactose. Mitochondria operated closer to state 3 respiration and had a lower mitochondrial membrane potential and basal mitochondrial O2 (•-) level compared to cells in the glucose model. An antimycin A (AA) dose response revealed that there was no difference in the sensitivity of OCR to AA inhibition between glucose and galactose cells. Importantly, cells in glucose were able to up-regulate glycolysis, while galactose cells were not. These results confirm that L6 cells are able to adapt to growth in a galactose media model and are consequently more susceptible to mitochondrial toxicants.

The basis for skeletal muscle dysfunction in phosphate-deficient patients and animals is not known, but it is hypothesized that intracellular phosphate deficiency leads to a defect in ATP synthesis. To test this hypothesis, changes in muscle function and nucleotide metabolism were studied in an animal model of hypophosphatemia. Mice were made hypophosphatemic through restriction of dietary phosphate intake. Gastrocnemius function was assessed in situ by recording isometric tension developed after stimulation of the nerve innervating this muscle. Changes in purine nucleotide, nucleoside, and base content of the muscle were quantitated at several time points during stimulation and recovery. Serum concentration and skeletal muscle content of phosphorous are reduced by 55 and 45%, respectively, in the dietary restricted animals. The gastrocnemius muscle of the phosphate-deficient mice fatigues more rapidly compared with control mice. ATP and creatine phosphate content fall to a comparable extent during fatigue in the muscle from both groups of animals; AMP, inosine, and hypoxanthine (indices of ATP catabolism) appear in higher concentration in the muscle of phosphate-deficient animals. Since total ATP use in contracting muscle is closely linked to total developed tension, we conclude that the comparable drop in ATP content in association with a more rapid loss of tension is best explained by a slower rate of ATP synthesis in the muscle of phosphate-deficient animals. During the period of recovery after muscle stimulation, ATP use for contraction is minimal, since the muscle is at rest. In the recovery period, ATP content returns to resting levels more slowly in the phosphate-deficient than in the control animals. In association with the slower rate of ATP repletion, the precursors inosine monophosphate and AMP remain elevated for a longer period of time in the muscle of phosphate-deficient animals. The slower rate of ATP repletion correlates with delayed return of normal muscle contractility in the phosphate-deficient mice. These studies suggest that the slower rate of repletion of the ATP pool may be the consequence of a slower rate of ATP synthesis and this is in part responsible for the delayed recovery of normal muscle contractility.

Toxicological sciences : an official journal of the Society of Toxicology, 97(2), 539–47. doi:10.1093/toxsci/kfm052

Many highly proliferative cells generate almost all ATP via glycolysis despite abundant O(2) and a normal complement of fully functional mitochondria, a circumstance known as the Crabtree effect. Such anaerobically poised cells are resistant to xenobiotics that impair mitochondrial function, such as the inhibitors rotenone, antimycin, oligomycin, and compounds like carbonyl cyanide 4-(trifluoromethoxy)phenylhydrazone (FCCP), that uncouple the respiratory electron transfer system from phosphorylation. These cells are also resistant to the toxicity of many drugs whose deleterious side effect profiles are either caused, or exacerbated, by impairment of mitochondrial function. Drug-induced mitochondrial toxicity is shown by members of important drug classes, including the thiazolidinediones, statins, fibrates, antivirals, antibiotics, and anticancer agents. To increase detection of drug-induced mitochondrial effects in a preclinical cell-based assay, HepG2 cells were forced to rely on mitochondrial oxidative phosphorylation rather than glycolysis by substituting galactose for glucose in the growth media. Oxygen consumption doubles in galactose-grown HepG2 cells and their susceptibility to canonical mitochondrial toxicants correspondingly increases. Similarly, toxicity of several drugs with known mitochondrial liabilities is more readily apparent in aerobically poised HepG2 cells compared to glucose-grown cells. Some drugs were equally toxic to both glucose- and galactose-grown cells, suggesting that mitochondrial impairment is likely secondary to other cytotoxic mechanisms.

Sustained arterial hypertension developed in male, albino rats chronically fed diets rich in sodium chloride with demineralized drinking water available ad libitum. After 12 months of the experimental regimen a positive, linear correlation (r = 0.91) was found between the systolic blood pressure and the concentration of sodium chloride in the diet. A syndrome of edema and renal failure was observed in 18 per cent of the group fed at the level of 7.0 to 9.8 per cent of sodium chloride. Significant histologic changes occurred in the kidneys and certain other organs in rats consuming rations containing these levels of NaCl. The relative volume of the radiosodium space was increased in the rat by high dietary sodium chloride.

The Crabtree effect (inhibition of respiration by glycolysis) is observed in cells with approximately equal glycolytic and respiratory capacities for ATP synthesis. Addition of glucose to aerobic suspensions of glucose-starved cells (Sarcoma 180 ascites tumor cells) causes a burst of respiration and lactate production due to ATP utilization for glucose phosphorylation by hexokinase and phosphofructokinase. This burst of activity is followed by inhibition of both respiration and glycolysis, the former to below the value before glucose addition (Crabtree effect). Both the respiratory rate and the glycolytic flux appear to be regulated by the cytosolic [ATP]/[ADP][Pi] albeit by completely different mechanisms. Respiration is regulated by the free energy of hydrolysis of ATP, such that the rate increases as the [ATP]/[ADP][Pi] decreases and decreases as the [ATP]/[adp][Pi] increases. The regulatory enzymes of glycolysis are activated by ADP (AMP) and Pi and inhibited by ATP. Thus both respiration and glycolysis increase or decrease as the [ATP]/[ADP][Pi] decreases or increases. The parallel regulation of both ATP-producing pathways by this common metabolite ratio is consistent with the cytoplasmic [ATP]/[ADP][Pi] being an important determinant of homeostatic regulation of cellular energy metabolism.

Low phosphorus: What to do, what to do?

Another shorter one.

As we can see, low phosphorus makes people miserable (De Lorenzo, Hargreaves, & Kakkar, 1998; Land et al., 1993; Laroche, 2001).

There are some mentions of oral supplements and such but I think it is best just to eat meat. And continue eating your dairy.

Phosphate depletion is associated with neuromuscular dysfunction due to changes in mitochondrial respiration that result in a defect of intracellular oxidative metabolism. Phosphate diabetes causes phosphate depletion due to abnormal renal re-absorption of phosphate be the proximal renal tubule. Most of the symptoms presented by patients with phosphate diabetes such as myalgia, fatigue and mild depression, are also common in patients with chronic fatigue syndrome, but this differential diagnosis has not been considered. We investigated the possible association between chronic fatigue syndrome and phosphate diabetes in 87 patients who fulfilled the criteria for chronic fatigue syndrome. Control subjects were 37 volunteers, who explicitly denied fatigue and chronic illness on a screening questionnaire. Re-absorption of phosphate by the proximal renal tubule, phosphate clearance and renal threshold phosphate concentration were the main outcome measures in both groups. Of the 87 patients with chronic fatigue syndrome, nine also fulfilled the diagnostic criteria for phosphate diabetes. In conclusion, we report a previously undefined relationship between chronic fatigue syndrome and phosphate diabetes. Phosphate diabetes should be considered in differential diagnosis with chronic fatigue syndrome; further studies are needed to investigate the incidence of phosphate diabetes in patients with chronic fatigue syndrome and the possible beneficial effect of vitamin D and oral phosphate supplements.

A 57-yr-old man presented with a long history of undiagnosed fatigue but no evidence of bone disease. He was noted to have hypophosphatemia due to an idiopathic phosphaturia. Marked abnormalities of exercising skeletal muscle detected by phosphorus magnetic resonance spectroscopy and by plasma metabolite measurements were consistent with mitochondrial dysfunction. Oral phosphate supplements restored plasma phosphate concentration and muscle biochemistry to normal and produced considerable improvement in symptoms and exercise tolerance, although the phosphate concentration in muscle was only marginally low and increased little by treatment. We conclude that hypophosphatemia should be excluded in unexplained fatigue.

A component of ATP, phosphate is at the hub of the energy-related mechanisms operative in muscle cells. Together with calcium, phosphate is involved in bone tissue mineralization: thus, a chronic alteration in the metabolism of phosphate can induce bone and joint disorders. Diagnosis of chronic hypophosphatemia. Serum phosphate, calcium, and creatinine should be assayed simultaneously. Serum calcium is increased in hypophosphatemia caused by hyperparathyroidism and decreased in osteomalacia. Urinary phosphate excretion should be measured in patients with a normal serum calcium level and a serum phosphate level lower than 0.80 mmol/L. A decrease in urinary phosphate excretion to less than 10 mmol/24 h strongly suggests a gastrointestinal disorder, such as malabsorption, antacid use, or chronic alcohol abuse. In patients with a urinary phosphate excretion greater than 20 mmol/24 h, the maximal rate of tubular reabsorption of phosphate (TmPO4) and the ratio of TmPO4 over glomerular filtration rate (GFR) should be determined to look for phosphate diabetes. Manifestations and causes of phosphate diabetes in adults. Moderately severe phosphate diabetes in adults manifests as chronic fatigue, depression, spinal pain, and polyarthralgia, with osteoporosis ascribable to increased bone resorption. Although many cases are idiopathic, investigations should be done to look for X-linked vitamin D-resistant rickets missed during childhood, a mesenchymatous tumor, or Fanconi’s syndrome with renal wasting of phosphate, glucose, and amino acids. Management of phosphate diabetes. Phosphate supplementation and, in patients with normal urinary calcium excretion, calcitriol produce some improvement in the symptoms and increase the bone mineral density. Whether dipyramidole is clinically effective remains unclear.

Energy and Structure: Phosphorus

Short post.

Ah, phosphorus. Sounds like the name of a Greek mythology character. Before I discuss glucose and carbon dioxide in response to some comments on the last post, I wanted to discuss a bit about phosphorus.

Meat is good, especially ruminant meat, all the bits you love and all the bits that induce a gag reflex, especially when you can get a hold of the grass fed sorts.

Phosphorus is important.

ATP is good. Adenosine triphosphate.

A lot of readers who read this blog are concerned about calcium and phosphorus. There is this thought pattern that less phosphate is better, which leads to phosphate is harmful, which eventually leads to a less is more type of mentality i.e. restriction.

Your ability to produce ATP is pretty important. You don’t just consume glucose and then phosphate appears from nowhere. It has to come from somewhere. Bad things happen when you eat a lot of carbohydrate and there is a lack of phosphorous in the diet, as carbohydrate places a demand on hexokinase, which requires phosphate to bind glucose to phosphate (glucose-6-phosphate) during glycolysis.

What happens when you are fed a phosphorus deficient diet? (Hettleman, Sabina, Drezner, Holmes, & Swain, 1983; Kilic, Demirkol, Ucsel, Citak, & Karabocuoglu, 2012)

Since the amount of phosphorous in your food is going to have an impact on ATP production, and ATP is the energy currency of cells, you can expect that a deficiency is going to systematically effect the entire organism. Indeed that is what we see in hypophosphatemia: weakness, bone pain, increased susceptibility to infection, numbness and tingling of the extremities, appetite suppression, cold extremities, difficulty swallowing, and a host of other “hypo” like symptoms.

Aside: Fructose is particularly effective at wasting phosphorus as well as inhibiting the absorption of calcium (Bergstra, Lemmens, & Beynen, 1993; Burch et al., 1980; Douard et al., 2010, 2013; Kizhner & Werman, 2002).

The effect of dietary fructose vs. glucose on kidney calcification (nephrocalcinosis) was studied in female rats. Fructose or glucose was incorporated into purified diets formulated either according to the nutrient requirements of rats or made nephrocalcinogenic by the addition of phosphorus (19.4 instead of 12.9 mmol/100 g diet) or by restriction of magnesium (0.8 instead of 1.6 mmol/100 g diet). Irrespective of the background composition of the diet, fructose consistently produced higher kidney calcium concentrations than did glucose. Fructose also raised kidney weight, expressed either as wet weight relative to body weight or as absolute dry weight; this greater kidney weight was not explained by the extra calcium. Fructose generally induced greater urinary concentrations of phosphorus and magnesium and lowered urinary pH compared with glucose. The greater urinary phosphorus concentrations in rats fed fructose may be responsible for the nephrocalcinogenic activity of this monosaccharide. Fructose stimulated the absorption of phosphorus and magnesium, which explains the higher concentrations of these minerals in the urine.

Rats were given large parenteral loads of fructose and the different segments of single nephrons then analyzed for fructose metabolites, fructose metabolizing enzymes, and nucleotide high energy phosphates. Fructokinase and fructose-1-P aldolase activities, and all the major metabolite and nucleotide effects, were confined to the proximal tubule. The proximal straight segment had the highest fructokinase and suffered the greatest changes. In this segment, fructose-1-P rose to 60 mmol/kg (dry weight basis) and glycerol-3-P and glucose-6-P reached 8 and 12 mmol/kg, respectively. ATP fell 80% and GTP (judging from the changes in GTP plus GDP) fell by the same percentage, but UTP was less affected. Total adenylate decreased 50%. In the proximal convoluted tubule, where fructokinase was lower and fructose-1-P aldolase higher than in the straight segment, fructose-1-P rose ony one-fourth as much and glucose-6-P was almost unchanged. In contrast, glycerol-3-P rose more, reaching 16 mmol/kg. Other substances measured along the nephron were glycerol-3-P dehydrogenase, fructose-1,6-bisphosphate aldolase, fructose, glucose, fructose bisphosphate, triose phosphate, and 6-P-gluconate. Control ATP levels were found to be highest in the distal tubule.

Dietary fructose inhibits intestinal calcium absorption and induces vitamin D insufficiency in CKD. Journal of the American Society of Nephrology : JASN, 21(2), 261–71. doi:10.1681/ASN.2009080795

Renal disease leads to perturbations in calcium and phosphate homeostasis and vitamin D metabolism. Dietary fructose aggravates chronic kidney disease (CKD), but whether it also worsens CKD-induced derangements in calcium and phosphate homeostasis is unknown. Here, we fed rats diets containing 60% glucose or fructose for 1 mo beginning 6 wk after 5/6 nephrectomy or sham operation. Nephrectomized rats had markedly greater kidney weight, blood urea nitrogen, and serum levels of creatinine, phosphate, and calcium-phosphate product; dietary fructose significantly exacerbated all of these outcomes. Expression and activity of intestinal phosphate transporter, which did not change after nephrectomy or dietary fructose, did not correlate with hyperphosphatemia in 5/6-nephrectomized rats. Intestinal transport of calcium, however, decreased with dietary fructose, probably because of fructose-mediated downregulation of calbindin 9k. Serum calcium levels, however, were unaffected by nephrectomy and diet. Finally, only 5/6-nephrectomized rats that received dietary fructose demonstrated marked reductions in 25-hydroxyvitamin D(3) and 1,25-dihydroxyvitamin D(3) levels, despite upregulation of 1alpha-hydroxylase. In summary, excess dietary fructose inhibits intestinal calcium absorption, induces marked vitamin D insufficiency in CKD, and exacerbates other classical symptoms of the disease. Future studies should evaluate the relevance of monitoring fructose consumption in patients with CKD.

Endocrinology and metabolism, 304(12), E1303–13. doi:10.1152/ajpendo.00582.2012

We recently discovered that chronic high fructose intake by lactating rats prevented adaptive increases in rates of active intestinal Ca(2+) transport and in levels of 1,25-(OH)2D3, the active form of vitamin D. Since sufficient Ca(2+) absorption is essential for skeletal growth, our discovery may explain findings that excessive consumption of sweeteners compromises bone integrity in children. We tested the hypothesis that 1,25-(OH)2D3 mediates the inhibitory effect of excessive fructose intake on active Ca(2+) transport. First, compared with those fed glucose or starch, growing rats fed fructose for 4 wk had a marked reduction in intestinal Ca(2+) transport rate as well as in expression of intestinal and renal Ca(2+) transporters that was tightly associated with decreases in circulating levels of 1,25-(OH)2D3, bone length, and total bone ash weight but not with serum parathyroid hormone (PTH). Dietary fructose increased the expression of 24-hydroxylase (CYP24A1) and decreased that of 1α-hydroxylase (CYP27B1), suggesting that fructose might enhance the renal catabolism and impair the synthesis, respectively, of 1,25-(OH)2D3. Serum FGF23, which is secreted by osteocytes and inhibits CYP27B1 expression, was upregulated, suggesting a potential role of bone in mediating the fructose effects on 1,25-(OH)2D3 synthesis. Second, 1,25-(OH)2D3 treatment rescued the fructose effect and normalized intestinal and renal Ca(2+) transporter expression. The mechanism underlying the deleterious effect of excessive fructose intake on intestinal and renal Ca(2+) transporters is a reduction in serum levels of 1,25-(OH)2D3. This finding is significant because of the large amounts of fructose now consumed by Americans increasingly vulnerable to Ca(2+) and vitamin D deficiency.

The basis for skeletal muscle dysfunction in phosphate-deficient patients and animals is not known, but it is hypothesized that intracellular phosphate deficiency leads to a defect in ATP synthesis. To test this hypothesis, changes in muscle function and nucleotide metabolism were studied in an animal model of hypophosphatemia. Mice were made hypophosphatemic through restriction of dietary phosphate intake. Gastrocnemius function was assessed in situ by recording isometric tension developed after stimulation of the nerve innervating this muscle. Changes in purine nucleotide, nucleoside, and base content of the muscle were quantitated at several time points during stimulation and recovery. Serum concentration and skeletal muscle content of phosphorous are reduced by 55 and 45%, respectively, in the dietary restricted animals. The gastrocnemius muscle of the phosphate-deficient mice fatigues more rapidly compared with control mice. ATP and creatine phosphate content fall to a comparable extent during fatigue in the muscle from both groups of animals; AMP, inosine, and hypoxanthine (indices of ATP catabolism) appear in higher concentration in the muscle of phosphate-deficient animals. Since total ATP use in contracting muscle is closely linked to total developed tension, we conclude that the comparable drop in ATP content in association with a more rapid loss of tension is best explained by a slower rate of ATP synthesis in the muscle of phosphate-deficient animals. During the period of recovery after muscle stimulation, ATP use for contraction is minimal, since the muscle is at rest. In the recovery period, ATP content returns to resting levels more slowly in the phosphate-deficient than in the control animals. In association with the slower rate of ATP repletion, the precursors inosine monophosphate and AMP remain elevated for a longer period of time in the muscle of phosphate-deficient animals. The slower rate of ATP repletion correlates with delayed return of normal muscle contractility in the phosphate-deficient mice. These studies suggest that the slower rate of repletion of the ATP pool may be the consequence of a slower rate of ATP synthesis and this is in part responsible for the delayed recovery of normal muscle contractility.

PURPOSE: The aims of this study were to determine the prevalence of hypophosphatemia and to discuss the clinical implications of hypophosphatemia in critically ill children. MATERIALS AND METHODS: A retrospective review of the medical records of children admitted to the pediatric intensive care unit from December 2006 to December 2007 was conducted. RESULTS: In 60.2% (n = 71) of the patients, any serum phosphorous level at admission and at the third day or seventh day after admission to pediatric intensive care unit was in hypophosphatemic range. Sepsis was present in 22.9% (n = 27) of the children studied and was associated with hypophosphatemia (P = .02). Hypophosphatemia was also associated with use of furosemide (P = .04), use of steroid (P = .04), use of β(2) agonist (P = .026), and use of an H(2) blocker (P = .004). There was a significant association between hypophosphatemia and the rate to attain target caloric requirements by enteral route (P = .007). The median time to attain target caloric requirements by enteral route was 2.9 ± 1.9 (0.2-10) days in the normophosphatemic group and 4.4 ± 2.8 (0.3-12) days in the hypophosphatemic group. In the multiple regression model, solely the rate to attain the target caloric requirements by enteral route demonstrated independent association with hypophosphatemia (P = .006; β = .27; 95% confidence interval, 0.02-0.09). Significant association was found between hypophosphatemia and the duration of mechanical ventilation and between hypophosphatemia and pediatric intensive care unit length of stay (P = .02 and P = .001, respectively). CONCLUSIONS: Critically ill pediatric patients are prone to hypophosphatemia, especially if they cannot be fed early by enteral route. Hypophosphatemia is associated with an increased duration of mechanical ventilation and increased length of stay in the pediatric intensive care unit, suggesting that active repletion might improve these parameters.

The use of fructose as a pure sugar has considerably increased in the last 3 decades, especially as a sweetener in carbonated beverages. Our previous studies showed that long-term fructose intake adversely affected several age-related metabolic parameters. The purpose of the present study was to compare the consequences of long-term fructose intake with those of glucose or sucrose on renal morphology and on several biochemical parameters used to estimate renal function. Male rats were fed a commercial diet for 16 months, and had free access either to water (control) or to 250 g/L solutions of fructose, glucose, or sucrose. Fructose-drinking rats exhibited higher liver weights compare to the other dietary groups. Control rats excreted significantly less urinary output than all sugar groups, which did not differ from each other. No differences were observed in fasting plasma fructose, glucose, and creatinine levels, or in urinary glucose levels. Fructose consumption resulted in elevated urinary fructose levels, higher creatinine clearance, and marked proteinuria. The tested sugars had influence on the molecular weight distribution of urinary proteins in the ranges of 10 to 16, 25 to 35, and 75 to 85 kd. Histological examination revealed that fructose consumption led to the formation of foci of cortical tubular necrosis with chronic inflammatory infiltrate, accumulation of tubular hyaline casts, thickening of the Bowman’s capsule, mesangial thickening due to collagen deposits, and the occurrence of hemosiderin in tubular cells. These data suggest that fructose has a negative impact on kidney function and morphology. Further research is required to elucidate the precise mechanisms by which long-term fructose consumption hampers renal metabolism.

Before we can talk about how an organism functions, we need to understand its gross organization and have the ability to visualize it. We need language to create an analogy, we need an analogy to visualize things. Recently, I had a conversation with a someone on why I view saturated fat as a superior energy substrate. But before I could explain why, I had to explain how I view the organism. Below is our conversation.

(7:11:59 PM) Edward: oh man… big question… where to start…

(7:12:03 PM) Edward: o.k. so

(7:12:24 PM) Anonymous: haha

(7:12:47 PM) Edward: If me and Dr. Peat were to agree on one thing it would be that energy and structure are interdependent

(7:13:09 PM) Edward: and quite frankly that is not a new biological concept, it is older then he is

(7:14:05 PM) Edward: however, the difference between myself and Peat is the function of structure…

(7:15:29 PM) Edward: I think that structure, which is a invention of evolution is in place to deliver energy, because I think the structure exists to support the organization of the organism

(7:16:47 PM) Edward: he looks at it a bit differently inherently if he is promoting sugar which is a primitive fuel source… in other words there is no structure needed to deliver glucose to a cell

(7:18:50 PM) Edward: does that make sense what i said so far

(7:19:01 PM) Edward: at least what we disagree on

(7:19:28 PM) Anonymous: yeah

(7:19:37 PM) Edward: I need to full screen this chat window it’s getting serious in here

(7:19:53 PM) Anonymous: i did that a little while ago ;)

(7:19:57 PM) Edward: o.k. evidence of this is the vascular system, the CNS, the lymphatic system, etc

(7:20:06 PM) Edward: at least on a big scale

(7:20:23 PM) Edward: for a single celled organism we don’t need all that

(7:20:42 PM) Edward: it is happy eating sugar

(7:21:25 PM) Edward: those systems are “structure”… in biology we say cells, tissue, organs, organ system so on when we talk about structure

(7:21:36 PM) Edward: the entire digestive system is “structure”

(7:22:23 PM) Edward: that “structure” is designed to deliver nutrients and the such to all of the cells, tissue, organs, etc… in the body

(7:23:07 PM) Edward: now obviously i argue that saturated fat is a superior energy source

(7:26:25 PM) Edward: o.k. so in the body there are the different organs, the brain, the balls, the ovaries, the muscles, the heart, etc…

(7:26:42 PM) Edward: all of these require a different energy substrate…

(7:27:02 PM) Edward: for example, your balls like citrate

(7:27:47 PM) Edward: your brain likes lactate/a bit of glucose/a bit of ketones/and some specific kinds of fat

(7:28:10 PM) Edward: the muscles at rest and during most activity burn fat

(7:28:15 PM) Edward: the heart prefers it

(7:28:58 PM) Edward: the blood… ahh the blood… the blood cells have no mitochondria

(7:29:13 PM) Edward: guess where the brains gets part of it’s lactate from

(7:29:16 PM) Edward: ?

(7:29:28 PM) Edward: The anaerobic metabolism of the red blood cells

(7:30:18 PM) Edward: the colon likes butyric acid

(7:30:33 PM) Edward: so you see each part of the body likes something different

(7:31:04 PM) Edward: how is it possible to support those fuel demands?

(7:31:44 PM) Edward: you have to have structure, the vascular system, the lymphatic system, the CNS, the GI system, etc.

(7:32:27 PM) Edward: when we look at breast milk what do we see…

(7:32:42 PM) Edward: first we see percentages of all the different saturated fat chain lengths

(7:32:54 PM) Edward: short, medium, long, very long, etc

(7:33:00 PM) Edward: and then we see protein

7:33:09 PM) Edward: a splash of lactose

(7:33:23 PM) Edward: we also see some branched chain fatty acids

(7:33:37 PM) Edward: and a very tiny tiny bit of polyunsaturated fat

(7:34:08 PM) Edward: there are no ketones in milk at least not that i am aware of… and this is the hooker

(7:34:29 PM) Edward: a baby needs ketones… if a baby does not have ketones it will either die or be retarded

(7:34:57 PM) Edward: ketones serve as a cholesterol precursor and also serve as a precursor for some of the special lipids in the brain

(7:35:31 PM) Edward: give a baby glucose instead of breast feeding and it develops tumors on the brain

(7:35:52 PM) Edward: so how does the baby get the ketones it needs

(7:36:06 PM) Edward: via “structure”

(7:36:52 PM) Edward: the liver and brain can make ketones locally and delivers them to the brain… that is structure at play (ketones are probably produced elsewhere as well)

(7:37:09 PM) Edward: so remember… structure is essentially a group of cells that perform a specialized function

(7:37:24 PM) Edward: each individual cell does not have structure not in the sense we are talking about here

(7:38:02 PM) Edward: so the ketones are delivered to each cell via structure because the individual cell itself can not do this because it serves a different function

(7:38:15 PM) Edward: same with lactate

(7:38:42 PM) Edward: babies need lactate and so does the brain… the brain itself can’t do this

(7:39:08 PM) Edward: it has to be delivered by the anaerobic metabolism of the red blood cells and locally in the brain in the astrocyctes

(7:39:34 PM) Edward: does that make sense so far?

(7:40:44 PM) Anonymous: yeah, although i’m not aware of the astrocyctes

(7:41:12 PM) Edward: oh well, there are about a dozen or more different types of cells in the brain

(7:43:53 PM) Edward: o.k. glucose is a primitive fuel source it is “anti-structure” and so are polyunsatured fats but here it we have to make perfectly clear that the polyunsaturated fats are anti-structure as a fuel source, but the brain is indeed made of polyunsatured fat… that is structure… in this case the polyunsatured fats serve electric functions

(7:43:58 PM) Edward: does that make sense

(7:44:46 PM) Edward: so as a fuel polyunsaturated fast are anti-structure but that does not mean they can not be built by the body to serve a functional/structural purpose

(7:44:50 PM) Edward: ?

(7:44:58 PM) Anonymous: yep

(7:45:04 PM) Edward: cool

(7:45:35 PM) Edward: glucose can basically be absorbed through a gradient anywhere in the body

(7:46:51 PM) Edward: if you eat it it goes in your mouth, your mouth cells, your esophagus cells, your stomach, everywhere… you can make a glucose solution and inject it in your arm and your cells will use it you can squirt some up your ass and your colon cells will use it, you can put it on your skin, etc…

(7:47:29 PM) Edward: there is absolutely no structure required for any type of cell to use it

(7:47:50 PM) Edward: so the cells are intelligent

(7:47:54 PM) Edward: “intelligent”

(7:48:06 PM) Edward: they sense their environment

(7:48:20 PM) Edward: what happens when you are queuing?

(7:49:28 PM) Anonymous: as in waiting in line?

(7:49:46 PM) Edward: yes waiting in line

(8:00:24 PM) Edward: so some people would get their money before others and others would be waiting or pushed out of the way right?

(8:00:36 PM) Anonymous: yeah

(8:00:53 PM) Edward: congratulations you now understand why we get cancer

(8:01:17 PM) Edward: and this is why structure is so important

(8:01:42 PM) Edward: when you need something you know when you need it, you go to the bank, wait in line, and you get what you need

(8:01:54 PM) Edward: money = energy substrates

(8:02:57 PM) Edward: when you have no structure or you fill your body with a fuel that requires no structure you create an environment in the body where literally the first cell to absorb the the glucose wins at the expense of it’s sister cell

(8:03:03 PM) Edward: even if it is in the same organ

(8:03:32 PM) Edward: people who don’t wait in line and crowd around like in Germany they act like animals not civilized and chaos develops

(8:03:45 PM) Edward: this is very similar to what happens in the body

(8:04:40 PM) Edward: cancer and disease really is proof that we are made up of a group of primitive (individual) cells all working together

(8:05:27 PM) Edward: when a bunch of money drops from the sky the people scatter and fight for it, they don’t all put it in a pile and then split it equally right?

(8:05:42 PM) Anonymous: mmhmm

(8:06:03 PM) Edward: and as much as it seriously pains me to use this analogy gov’t is a good analogy to use for structure

(8:06:56 PM) Edward: obviously some gov’t are better than others and as a result each individual has a better life… some gov’t suck and then the individuals (the cells) have shitty lives

(8:07:25 PM) Edward: they starve, don’t have food, get disease

(8:07:27 PM) Edward: etc

I don’t know what to title this post: follow-up

This post is going to serve as a sort of summary for the posts that I will be writing on the relationship between thyroid hormones and saturated fat. I’ve been working on ways to make things understandable and trying to develop some analogies so we can get a visual in the brain.

The first concepts I will be covering is the behavior of T3 alone, what it does to your metabolism and how it functions. I hope to dissolve some myths concerning the type of metabolism T3 promotes and why perhaps taking T3 on a low fat diet might be a mistake which can increase stress as well as making one more sensitive to stress.

From there I will work into the behavior of saturated fat alone, what it does to your metabolism, and how it functions. I hope to dissolve some myths concerning the type of metabolism that saturated fat promotes. I also hope to make it perfectly clear that there is a difference between a high saturated fat diet and a high fat diet that is high in polyunsaturated fats. And I also hope to make clear the difference between free saturated fatty acids and free polyunsaturated fatty acids.

At that point some light bulbs should be turning on and I will compare the similarities between the thyroid hormones and saturated fat. I will use that post as a jumping off point to make some predictions about things we should see in reality and the literature if this concept is true which I will follow up with examples and supporting literature.

Then I will write posts on longevity, metabolic rate, disease, and dovetail all of these concepts together. I was struggling with either wanting to write one large article or a series. I decided on writing a series because it will allow me to manage my time a little better with my work schedule. Plus I am getting ready to transfer to a hospital in Connecticut so with that pending move there might be some delays here and there. But the delays will give you a chance to start digging around yourself and poke holes in things that I may have overlooked. It is important to be vigilant. I have been very thorough in looking to find exceptions but I am only one person, and the literature is massive, and maybe you will look  at things a little differently. And that is o.k., all we are after is answers to questions, and questioning assumptions.

Finally, always look for exceptions. It leads to great questions.

I don’t know what to title this post

Dusk-mobile-FW

A few years ago I started looking at the mechanisms through which T3 works. In my brain when I’m developing a model in my head, it needs to resemble a gently moving mobile; you know those things over a baby crib. It has to make sense, it has to look beautiful. I’ve always pictured everything in nature almost as a fractal.

I had noticed in some personal experiments that T3 reminded me of eating butter. A lot of the same symptoms T3 seemed to solve where the same symptoms butter seemed to solve. Things like that make me incredibly curious.

When you are looking at hormones it becomes tempting to read so much about the positive benefits of one hormone that you convince yourself that actually taking that hormone is a good idea. It is easy to look at the positive benefits of a substance and quickly forget to ask the question what is causing a flux in this particular hormone to begin with?

It is very easy to forget the flux and the balance. I picture in my head a glass full of different colored dyes all remaining separate yet blended together at their edges in beautiful gradients.

Even more important is that when you look at hormones, you can’t just look at the flux of different hormones to understand them. One hormone is always pushing or pulling another through a cascade. To really get down to the understanding of hormones and their function, you have to get down to the microscopic level where organization starts. What is it about multicellular organisms that makes all of the cells organize, what makes them work together, how do they know where to go? How does a blood cell know it is a blood cell, how does muscle cell know it belongs in your muscle instead of your brain. How come your toenails grow straight out instead of curling under and growing back into your toe? How come sperm cells know to attach to the egg instead of attaching to an epithelial cell?

Everyday curious minds are working on solving these mysteries. It is fascinating how much we know really. Utterly staggering. Almost every question I’ve ever cared to ask at one point or another has been studied in some form or fashion, or at least part of the question has been studied.

These days what we are lacking most of all are creative people who can move objects in space in their brains. These days people are super concerned with data points instead of prediction power. Prediction power is the ultimate test for any theory. And as I’ve said many times if you don’t have prediction power or if your model can’t predict an exception then it’s time to go back to the drawing board.

You have to constantly back check everything from the microscopic to the macroscopic. You can never be too careful in coming to conclusions. Especially when it comes to your own health.

As I said, it made me incredibly curious when I noticed that T3 solved the same problems butter seemed to solve. So I began looking for a connection. I have a lot of posts I’m supposed to be writing and for now they will be put on hold. From here on out I will be focusing on writing about the connection between T3 and butter.

Nicotine, BAT thermogenesis, UCPs

Nicotine uncouples the mitochondria via UCP1 (uncoupling protein 1, or thermogenin). It upregulates BAT thermogensis (brown adipose tissue) and increases in BAT thermogenesis is associated with increased longevity. I could see nicotine, aside from butter, promoting longevity. 

Mattson, M. P. (2010). Perspective: Does brown fat protect against diseases of aging? Ageing research reviews, 9(1), 69–76. doi:10.1016/j.arr.2009.11.004

The most commonly studied laboratory rodents possess a specialized form of fat called brown adipose tissue (BAT) that generates heat to help maintain body temperature in cold environments. In humans, BAT is abundant during embryonic and early postnatal development, but is absent or present in relatively small amounts in adults where it is located in paracervical and supraclavicular regions. BAT cells can “burn” fatty acid energy substrates to generate heat because they possess large numbers of mitochondria in which oxidative phosphorylation is uncoupled from ATP production as a result of a transmembrane proton leak mediated by uncoupling protein 1 (UCP1). Studies of rodents in which BAT levels are either increased or decreased have revealed a role for BAT in protection against diet-induced obesity. Data suggest that individuals with low levels of BAT are prone to obesity, insulin resistance and cardiovascular disease, whereas those with higher levels of BAT maintain lower body weights and exhibit superior health as they age. BAT levels decrease during aging, and dietary energy restriction increases BAT activity and protects multiple organ systems including the nervous system against age-related dysfunction and degeneration. Future studies in which the effects of specific manipulations of BAT levels and thermogenic activity on disease processes in animal models (diabetes, cardiovascular disease, cancers, neurodegenerative diseases) are determined will establish if and how BAT affects the development and progression of age-related diseases. Data from animal studies suggest that BAT and mitochondrial uncoupling can be targeted for interventions to prevent and treat obesity and age-related diseases. Examples include: diet and lifestyle changes; specific regimens of mild intermittent stress; drugs that stimulate BAT formation and activity; induction of brown adipose cell progenitors in muscle and other tissues; and transplantation of brown adipose cells.

Yoshida, T., Yoshioka, K., Hiraoka, N., & Kondo, M. (1990). Effect of nicotine on norepinephrine turnover and thermogenesis in brown adipose tissue and metabolic rate in MSG obese mice. Journal of nutritional science and vitaminology, 36(2), 123–30. Retrieved from http://europepmc.org/abstract/MED/2388096

To clarify whether nicotine stimulates the sympathetic nervous system (SNS) and thermogenesis in brown adipose tissue (BAT) and whether it promotes the resting metabolic rate (RMR), with resulting mitigation of obesity, we measured norepinephrine (NE) turnover (an indicator of SNS activity), guanosine-5’-diphosphate (GDP) binding (a thermogenic indicator), oxygen consumption in BAT, and RMR in monosodium-L-glutamate (MSG) obese and saline control mice after 2 weeks treatment with nicotine. Nicotine significantly increased NE turnover, GDP binding, oxygen consumption in BAT, and RMR, and significantly reduced body weight in MSG obese mice as well as in control mice without affecting food intake. These results suggest that nicotine stimulates NE turnover and thermogenesis in BAT, and promotes RMR, all of which contribute to the mitigation of obesity.

BACKGROUND: Understanding of nonalcoholic steatohepatitis (NASH) is hampered by the lack of a suitable model. Our aim was to investigate whether long term high saturated-fat feeding would induce NASH in rats. METHODS: 21 day-old rats fed high fat diets for 14 weeks, with either coconut oil or butter, and were compared with rats feeding a standard diet or a methionine choline-deficient (MCD) diet, a non physiological model of NASH. RESULTS: MCDD fed rats rapidly lost weight and showed NASH features. Rats fed coconut (86% of saturated fatty acid) or butter (51% of saturated fatty acid) had an increased caloric intake (+143% and +30%). At the end of the study period, total lipid ingestion in term of percentage of energy intake was higher in both coconut (45%) and butter (42%) groups than in the standard (7%) diet group. No change in body mass was observed as compared with standard rats at the end of the experiment. However, high fat fed rats were fattier with enlarged white and brown adipose tissue (BAT) depots, but they showed no liver steatosis and no difference in triglyceride content in hepatocytes, as compared with standard rats. Absence of hepatic lipid accumulation with high fat diets was not related to a higher lipid oxidation by isolated hepatocytes (unchanged ketogenesis and oxygen consumption) or hepatic mitochondrial respiration but was rather associated with a rise in BAT uncoupling protein UCP1 (+25-28% vs standard). CONCLUSION: Long term high saturated fat feeding led to increased “peripheral” fat storage and BAT thermogenesis but did not induce hepatic steatosis and NASH.

Di Paola, M., & Lorusso, M. (2006). Interaction of free fatty acids with mitochondria: coupling, uncoupling and permeability transition. Biochimica et biophysica acta, 1757(9-10), 1330–7. doi:10.1016/j.bbabio.2006.03.024 

Long chain free fatty acids (FFA) exert, according to their actual concentration, different effects on the energy conserving system of mitochondria. Sub-micromolar concentrations of arachidonic acid (AA) rescue DeltapH-dependent depression of the proton pumping activity of the bc1 complex. This effect appears to be due to a direct interaction of AA with the proton-input mouth of the pump. At micromolar concentrations FFA increase the proton conductance of the inner membrane acting as protonophores. FFA can act as natural uncouplers, causing a mild uncoupling, which prevents reactive oxygen species production in the respiratory resting state. When Ca(2+)-loaded mitochondria are exposed to micromolar concentrations of FFA, the permeability of the inner membrane increases, resulting in matrix swelling, rupture of the outer membrane and release of intermembrane pro-apoptotic proteins. The characteristics of AA-induced swelling appear markedly different in mitochondria isolated from heart or liver. While in the latter it presents the canonical features of the classical permeability transition (PT), in heart mitochondria substantial differences are observed concerning CsA sensitivity, DeltaPsi dependence, reversibility by BSA and specificity for the activating divalent cation. In heart mitochondria, the AA-dependent increase of the inner membrane permeability is affected by ANT ligands such as adenine nucleotides and atractyloside. AA apparently causes a Ca2+-mediated conversion of ANT from a translocator to a channel system. Upon diamide treatment of heart mitochondria, the Ca2+/AA-induced CsA insensitive channel is converted into the classical PT pore. The relevance of these observations in terms of tissue-specific components of the putative PTP and heart ischemic and post-ischemic process is discussed.

ApoE4: This is your brain on ApoE4

At least until the CHO breaks you…

Dennis, N. a, Browndyke, J. N., Stokes, J., Need, A., Burke, J. R., Welsh-Bohmer, K. a, & Cabeza, R. (2010). Temporal lobe functional activity and connectivity in young adult APOE varepsilon4 carriers. Alzheimer’s & dementia : the journal of the Alzheimer’s Association, 6(4), 303–11. doi:10.1016/j.jalz.2009.07.003

BACKGROUND: We sought to determine if the APOE epsilon4 allele influences both the functional activation and connectivity of the medial temporal lobes (MTLs) during successful memory encoding in young adults. METHODS: Twenty-four healthy young adults, i.e., 12 carriers and 12 noncarriers of the APOE epsilon4 allele, were scanned in a subsequent-memory paradigm, using event-related functional magnetic resonance imaging. The neuroanatomic correlates of successful encoding were measured as greater neural activity for subsequently remembered versus forgotten task items, or in short, encoding success activity (ESA). Group differences in ESA within the MTLs, as well as whole-brain functional connectivity with the MTLs, were assessed. RESULTS: In the absence of demographic or performance differences, APOE epsilon4 allele carriers exhibited greater bilateral MTL activity relative to noncarriers while accomplishing the same encoding task. Moreover, whereas epsilon4 carriers demonstrated a greater functional connectivity of ESA-related MTL activity with the posterior cingulate and other peri-limbic regions, reductions in overall connectivity were found across the anterior and posterior cortices. CONCLUSIONS: These results suggest that the APOE varepsilon4 allele may influence not only functional activations within the MTL, but functional connectivity of the MTLs to other regions implicated in memory encoding. Enhanced functional connectivity of the MTLs with the posterior cingulate in young adult epsilon4 carriers suggests that APOE may be expressed early in brain regions known to be involved in Alzheimer’s disease, long before late-onset dementia is a practical risk or consideration. These functional connectivity differences may also reflect pleiotropic effects of APOE during early development.

Evans, S., Gray, M. A., Dowell, N. G., Tabet, N., Tofts, P. S., King, S. L., & Rusted, J. M. (2013). APOE E4 Carriers show prospective memory enhancement under nicotine, and evidence for specialisation within medial BA10. Neuropsychopharmacology : official publication of the American College of Neuropsychopharmacology, 38(4), 655–63. doi:10.1038/npp.2012.230

There is evidence to suggest that the APOE ɛ4 allele (which confers an increased risk of developing dementia) might be associated with cognitive advantages earlier in life. Further, nicotine might selectively benefit ɛ4 carriers. We used fMRI to explore performance on a prospective memory (PM) task in young adults (age 18-30) with and without nicotine using a within-subjects design. Participants performed an ongoing task while retaining a PM instruction to respond to specific stimuli embedded in the task. Nicotine effects varied according to APOE status. Reaction times to the PM cue were improved under nicotine in ɛ4 carriers, but not in ɛ3 carriers. In an event-related analysis, extrastriate responses to PM trials were enhanced by nicotine only in ɛ4 carriers. These differences in early visual processing may contribute to the behavioral findings. Activity in medial BA10 (previously implicated in PM) differentiated ɛ4 from ɛ3 carriers. One BA10 subregion showed greater deactivation in ɛ4 carriers during PM trials. Activity in other BA10 subregions was modulated by PM reaction time, pointing to region-specific effects within medial BA10. In addition, activity in right hippocampal formation was only seen in ɛ4 carriers receiving nicotine. These results demonstrate that cognitive enhancement by nicotine can selectively benefit APOE ɛ4 carriers, and point to genotype-specific differences in neural activity during PM. In addition, these results show that the role of medial BA10 in PM likely involves varying contributions from functionally specific subregions.

Proceedings of the National Academy of Sciences of the United States of America, 106(17), 7209–14. doi:10.1073/pnas.0811879106

The APOE epsilon4 allele is a risk factor for late-life pathological changes that is also associated with anatomical and functional brain changes in middle-aged and elderly healthy subjects. We investigated structural and functional effects of the APOE polymorphism in 18 young healthy APOE epsilon4-carriers and 18 matched noncarriers (age range: 20-35 years). Brain activity was studied both at rest and during an encoding memory paradigm using blood oxygen level-dependent fMRI. Resting fMRI revealed increased “default mode network” (involving retrosplenial, medial temporal, and medial-prefrontal cortical areas) coactivation in epsilon4-carriers relative to noncarriers. The encoding task produced greater hippocampal activation in epsilon4-carriers relative to noncarriers. Neither result could be explained by differences in memory performance, brain morphology, or resting cerebral blood flow. The APOE epsilon4 allele modulates brain function decades before any clinical or neurophysiological expression of neurodegenerative processes.

The apolipoprotein E (APOE) epsilon4 allele is the major genetic risk factor for Alzheimer’s disease, but an APOE effect on memory performance and memory-related neurophysiology in young, healthy subjects is unknown. We found an association of APOE epsilon4 with better episodic memory compared with APOE epsilon2 and epsilon3 in 340 young, healthy persons. Neuroimaging was performed in a subset of 34 memory-matched individuals to study genetic effects on memory-related brain activity independently of differential performance. E4 carriers decreased brain activity over 3 learning runs, whereas epsilon2 and epsilon3 carriers increased activity. This smaller neural investment of epsilon4 carriers into learning reappeared during retrieval: epsilon4 carriers exhibited reduced retrieval-related activity with equal retrieval performance. APOE isoforms had no differential effects on cognitive measures other than memory, brain volumes, and brain activity related to working memory. We suggest that APOE epsilon4 is associated with good episodic memory and an economic use of memory-related neural resources in young, healthy humans.

The APOE-ɛ4 allele is associated with increased cognitive decline during normal aging and Alzheimer’s disease. However, several studies intriguingly found a beneficial effect on cognition in young adult human APOE-ɛ4 carriers. Here, we show that 3-month old bigenic hAPP-Yac/apoE4-TR mice outperformed their hAPP-Yac/apoE3-TR counterparts on learning and memory performances in the highly hippocampus-dependent, hidden-platform version of the Morris water maze task. The two mouse lines did not differ in a non-spatial visible-platform version of the task. This hAPP-Yac/apoE-TR model may thus provide a useful tool to study the mechanisms involved in the antagonistic pleiotropic effects of APOE-ɛ4 on cognitive functions.

The APOE e4 allele, which confers an increased risk of developing dementia in older adulthood, has been associated with enhanced cognitive performance in younger adults. An objective of the current study was to compare task-related behavioural and neural signatures for e4 carriers (e4+) and non-e4 carriers (e4-) to help elucidate potential mechanisms behind such cognitive differences. On two measures of attention, we recorded clear behavioural advantages in young adult e4+ relative to e4-, suggesting that e4+ performed these tasks with a wider field of attention. Behavioural advantages were associated with increased task-related brain activations detected by fMRI (BOLD). In addition, behavioural measures correlated with structural measures derived from a former DTI analysis of white matter integrity in our cohort. These data provide clear support for an antagonistic pleiotropy hypothesis–that the e4 allele confers some cognitive advantage in early life despite adverse consequences in old age. The data implicate differences in both structural and functional signatures as complementary mediators of the behavioural advantage.

Jan Kwasniewski: muscle cramps

Wanted to add this little clip from Homo Optimus as an addition to my comment regarding DOMS.

Did you try to recommend the optimal diet for the sports people?

I did indeed. There is a leading football team in Poland for the players of which, some time ago, I recommended correct nutrition. They are resistant to fatigue, play aggressively, and typically score goals in the second half when their opposition is falling apart. And one more important detail – they do not have muscle cramps, and suffer injuries much less often than other players.

Not sure how well the Polish team referenced here play or which one it is; more interested in the lack of muscle cramps.

Jan Kwasniewski: unsaturated fats

I have been reading through Jan Kwasniewski’s book Homo Optimus and came across this bit:

Those who are not interested can skip the next few lines, but I would like to explain these processes which lead to advantageous or harmful changes in our bodies. Unsaturated fats, we are told – essential unsaturated fats – are present in mother’s milk at the concentration of 0.4%. No one can dispute that mother’s milk is the ideal nutrition, as far as the biochemical composition is concerned. It contains 3 to [illegible] grams of fat per 1 gram of protein. The conclusion is obvious – if Nature included such a minute quantity of that constituent in such a wonder food, then we should respect it. Meanwhile, people are being persuaded that plant-derived fats containing polyunsaturated fatty acids which do not exist in mother’s milk, are healthy. Nothing is more misleading – in the body they participate in reaction by binding oxygen. Peroxides, superoxides, various other poisons accelerating the formation of atherosclerosis are formed; aging of tissues, mechanical damage, cancer formation occurs. Some time ago, experiments were conducted investigating the effects of the replacement in a diet of saturated fat with unsaturated fats. What was concluded? Patients who were fed unsaturated fats were getting cancer 3-4, even 5 times more often than patients on the same proportion of saturated fats. Its is obvious why. Peroxides, which I have already mentioned, induce inflammations in the body, disease states, they simply degenerate tissues and whole organs. This concerns polyunsaturated fats only, those not present in butter, but instead present in plant-derived oils. That is not the end to it. In the bodies nourished with polyunsaturated fat the chemical compound called malate aldehyde is formed – terrible stuff. Technical gases such as ethane and pentane are also formed, excreted by the body, defending itself against the poisoning. However, together with these gases we also excrete hydrogen – the best fuel for our tissues.

I like that he mentions the aldehydes produced when polyunsaturated fats are oxidized. As he says, “terrible stuff”.

Cooking your food proper: soft-boiled eggs

This is one of the most useful tips I’ve come across for getting perfect soft-boiled eggs with a pan and water. This method makes a huge difference in repeatable consistency. If you keep your eggs on the counter at room temperature (which was something I picked up when living in Germany) the cooking times will be about a minute to a minute and a half shorter depending on the consistency you like. I have been happy with 6 minutes and then a quick rinse in cold water, not too long in the cold water because I like the yolk to still have a creamy warm texture. A superior cooking method would be Sous-vide.

Origin of mitochondria

I think that this website is interesting considering the endosymbiotic theory of the origin of mitochondria is the explanation usually given for the origin of the organelle (the other is the autogenic one). And now it seems the origin of the peroxisome might get the same canned answer for its origin.

I remember the first time I read about the idea that mitochondria were essentially prokaryotic cells that took up residency in eukaryotic cells. The story I read seemed rather fairy-tale like.

Fermented dairy, lactic acid, and CLA: Dr. Peat’s thoughts on lactic acid bacteria

“The lactic acid bacteria are themselves anti-inflammatory, but if they live in the upper intestine (because of hypothyroidism) they might be able to convert sugar to lactic acid, which would be stressful for the liver. Any lactic acid can promote inflammation, but bacterial DL-lactic acid is worse, so it shouldn’t be used in large amounts.” ~Dr. Peat via e-mail

Lactic acid bacteria seem to be anti-inflammatory. There are several isomers of lactate/lactic acid and they have differing physiological effects. The literature is supportive of the anti-inflammatory effects of lactic acid bacteria, and anecdotal and historical accounts support the literature. The literature also seems to support a positive effect for the lactic acid produced by lactic acid bacteria, which contrasts with Dr. Peat.

In the meantime have a look through the literature below and a look at Lactated Ringer’s Solution.

Time to eat.

De Luis, D. A., Varela, C., de La Calle, H., Cantón, R., de Argila, C. M., San Roman, A. L., & Boixeda, D. (1998). Helicobacter pylori infection is markedly increased in patients with autoimmune atrophic thyroiditis. Journal of clinical gastroenterology, 26(4), 259–63. Retrieved from http://www.ncbi.nlm.nih.gov/pubmed/9649006

Infection by viral or bacterial pathogens has been suspected in playing a role in the development of autoimmune thyroid disease. Because Helicobacter pylori might be involved in the development of nongastrointestinal conditions such as rosacea, ischemic heart disease, and diabetes mellitus, we evaluated the prevalence of H. pylori infection in patients with autoimmune thyroid disease. Fifty-nine patients with autoimmune thyroid disease were included: autoimmune atrophic thyroiditis (n=21), Hashimoto’s thyroiditis (n=18), and Graves’ disease (n=20). Twenty patients with nontoxic multinodular goiter served as controls for nonautoimmune thyroid disease, and 11 patients with Addison’s disease served as controls for nonthyroid endocrine autoimmune disease. The levels of anti-H. pylori immunoglobulin G (IgG) were determined, and a radiolabeled urea breath test were performed. The prevalence of H. pylori infection was markedly increased in the patients with autoimmune atrophic thyroiditis (85.7%), compared with the controls with nontoxic multinodular goiter (40%) and Addison’s disease (45.4%). Infection by H. pylori resulted in increased levels of gastrin, pepsinogen I, and pepsinogen II in the H. pylori-positive groups, compared with the H. pylori-negative groups. A positive linear regression was found between the levels of microsomal autoantibodies and those of anti-H. pylori IgG in patients with autoimmune atrophic thyroiditis (n=21; r=0.79; p < 0.01). Finally, and although the overall prevalence of H. pylori infection was not increased, the anti-H. pylori IgG levels and the results from the breath test were higher in the patients with Graves’ disease and Hashimoto’s thyroiditis patients than in the controls. Clearly, the prevalence of H. pylori infection is increased in autoimmune atrophic thyroiditis and results in abnormalities of gastric secretory function. The strong relation between the levels of anti-H. pylori IgG and the levels of microsomal antibodies suggests that H. pylori antigens might be involved in the development of autoimmune atrophic thyroiditis or that autoimmune function in autoimmune atrophic thyroiditis may increase the likelihood of H. pylori infection.

In this study the effects of both pH and organic acids on Helicobacter pylori NCTC 11637 were tested. Lactobacillus acidophilus, Lact. casei, Lact. bulgaricus, Pediococcus pentosaceus and Bifidobacterium bifidus were assayed for their lactic acid production, pH and inhibition of H. pylori growth. A standard antimicrobial plate well diffusion assay was employed to examine inhibitory effects. Lactic, acetic and hydrochloric acids demonstrated inhibition of H. pylori growth in a concentration-dependent manner with the lactic acid demonstrating the greatest inhibition. This inhibition was due both to the pH of the solution and its concentration. Six strains of Lact. acidophilus and one strain of Lact. casei subsp. rhamnosus inhibited H. pylori growth where as Bifidobacterium bifidus, Ped. pentosaceus and Lact. bulgaricus did not. Concentrations of lactic acid produced by these strains ranged from 50 to 156 mmol l-1 and correlated with H. pylori inhibition. The role of probiotic organisms and their metabolic by-products in the eradication of H. pylori in vivo remains to be determined.

Retrieved from http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=321236&tool=pmcentrez&rendertype=abstract

We studied the potential inhibitory effect of Lactobacillus casei strain Shirota (from the fermented milk product Yakult [Yakult Ltd., Tokyo, Japan]) on Helicobacter pylori by using (i) in vitro inhibition assays with H. pylori SS1 (Sydney strain 1) and nine H. pylori clinical isolates and (ii) the in vivo H. pylori SS1 mouse model of infection over a period of 9 months. In vitro activity against H. pylori SS1 and all of the clinical isolates was observed in the presence of viable L. casei strain Shirota cells but not in the cell-free culture supernatant, although there was profound inhibition of urease activity. In vivo experiments were performed by oral administration of L. casei strain Shirota in the water supply over a period of 9 months to 6-week-old C57BL/6 mice previously infected with H. pylori SS1 (study group; n = 25). Appropriate control groups of H. pylori-infected but untreated animals (n = 25) and uninfected animals given L. casei strain Shirota (n = 25) also were included in the study. H. pylori colonization and development of gastritis were assessed at 1, 2, 3, 6, and 9 months postinfection. A significant reduction in the levels of H. pylori colonization was observed in the antrum and body mucosa in vivo in the lactobacillus-treated study group, as assessed by viable cultures, compared to the levels in the H. pylori-infected control group. This reduction was accompanied by a significant decline in the associated chronic and active gastric mucosal inflammation observed at each time point throughout the observation period. A trend toward a decrease in the anti-H. pylori immunoglobulin G response was measured in the serum of the animals treated with lactobacillus, although this decrease was not significant.

Effect of frequent consumption of a Lactobacillus casei-containing milk drink in Helicobacter pylori-colonized subjects. Alimentary pharmacology & therapeutics17(3), 429–35. Retrieved from http://www.ncbi.nlm.nih.gov/pubmed/12562457

BACKGROUND: Several studies have reported inhibitory effects of lactic acid bacteria on bacterial pathogens. AIM: To test whether a drink containing Lactobacillus casei strain Shirota inhibits Helicobacter pylori growth. METHODS: The in vitro growth inhibition of H. pylori was studied when L. casei was added to plates previously inoculated with H. pylori reference strain NCTC 11637. In an intervention study, 14 H. pylori-positive subjects were given Yakult drink (10(8) colony-forming units/mL L. casei) thrice daily during meals for 3 weeks. Six untreated H. pylori-positive subjects served as controls. H. pylori bacterial loads were determined using the 13C-urea breath test, which was performed before and 3 weeks after the start of L. casei supplementation. RESULTS: In vitro, L. casei inhibits H. pylori growth. This effect was stronger with L. casei grown in milk solution than in DeMan-Rogosa-Sharpe medium. No growth inhibition was shown with medium inoculated with lactic acid, Escherichia coli strain DH5alpha or uninoculated medium. Filtration of L. casei culture before incubation with H. pylori completely abolished the inhibitory effect. Urease activity decreased in nine of the 14 (64%) subjects with L. casei supplementation and in two of the six (33%) controls (P = 0.22). CONCLUSIONS: Viable L. casei are required for H. pylori growth inhibition. This does not result from changes in lactic acid concentration. In addition, a slight, but non-significant, trend towards a suppressive effect of L. casei on H. pylori in vivo may exist.

Fermented dairy, lactic acid, and CLA: a response to James

James left a good comment on the Fermented dairy, lactic aicd, and CLA post. I started to reply as a comment but then it I felt it should be in a post as it was getting rather long.

James I always appreciate your comments.

There are reliable reports on the Maasai/Masai. For further exploration: Peter Dobromylskyj, Stephan Guyenet, Chris Masterjohn have all written on the Maasai. Ray Peat has also commented on the health of the Maasai:

“Many people advocate a low protein diet, specifically to prevent or treat osteoporosis, but the cultures that traditionally have had extremely high protein diets, such as the Masai, are very healthy.” (Peat, n.d.)

There are also interesting studies isolating the impacts of different types of fat in mice (Horn, Laver, & Wood, 1981; MacQueen, 2011).

The question of healthy, healthier, and healthiest is relative. There are many optimums in health and there is plenty of observational evidence to support this position; in the literature and anecdotal.

If I am in Europe and then go to the United States and see that the average population of Europe is healthier than the average population of the United States-clearly Europe is doing something different to achieve those results. Is Europe’s approach optimal, not necessarily, but one could argue that it is a step towards something better (a degree of improvement towards something optimal). If I am in an area of the world that has a high concentration of 90+ year old inhabitants and then move to an area where the phenomena is absent–regardless of the factors–if longevity is your goal, then in my opinion it is worth further exploration.

Another example: If I look at the longest lived and see that sucrose is relatively low, and I see evidence in the literature that sucrose is healthful, then the next question to be asked is if sucrose is a negative, neutral, or positive contributing factor to longevity and good health. If I see that some people who live a long time eat relatively little sugar and I see that some people also live long lives eating more sucrose, then I can see that there are apparently two different paradigms at work that perhaps achieve the same results. You can look at a pattern and develop a theory, but as soon as the pattern is broken it means the foundation on which the theory is based is flawed.

A comical example is if someone tells me that bacon is unhealthful and that industrial bacon is even more unhealthful. We walk away thinking bacon is unhealthful but industrial bacon is worse. But then we find a woman who is 100+ years old who gives responsibility of her longevity to the high quantities of bacon she eats that is more than likely less than pastured. So not only is she eating “harmful” bacon,  she is eating the worst of the worst. Is there a protective factor that protects from the negative factors of bacon? Or is it such that bacon, regardless of the source, is either a neutral or positive factor towards longevity?

Good health is usually a balance between the concepts of security and freedom.

I agree:

“I’m a bit skeptic about inferring that a habit or food is good based upon the apparent health of a population.”

However, the question I am raising is not a matter of health, it is a matter of toxicity. When a food dominates a particular diet and the population is in good health and it is claimed that same food is harmful, there is an irregularity. For example, if smoking is harmful and/or toxic, and the oldest person on earth smoked (as well as others in the record books) there is an irregularity. Either the toxin is indeed harmful and there is a protective factor or the toxin is not harmful; or the mechanism for harmfulness is incorrect or there are contextual considerations. A further example would be fatty acids such as those found in breast milk and coconut oil that are ketogenic. These fatty acids are ketogenic in their nature. If we agree that breast milk and coconut oil are good even though they produce ketones (or in the case of breast milk which enhances ketogenesis) then there are now at least two contexts for ketosis. One that is stimulated by metabolic substrates, and one that is produced in certain physiological situations (self-induced or as a result of disease). In a baby who is in ketosis we do not say that ketones are harmful, yet ketoacidosis in a diabetic is harmful. Clearly ketones are protective. But the context (physiological states) in which they are measured might lead some people to throw out the baby with the bath water. My opinion is that lactic acid and lactate have different contexts as well.

Your last question:

“But Ray Peat seems to think carb (esp. sugar – but let’s leave alone the debate on starch and endotoxin for now) is needed for good thyroid even once in good health – do you disagree and if so why?”

I think glucose is probably wise. How much is required for good health and stress resistance? I don’t know, but I think the requirement is rather low. I have a post on this topic that I have not yet had a chance to finish. Fresh meat contains glycogen which indeed is a source of glucose. That is something that I think is important which most miss when gauging carbohydrate requirements. Even then I have no idea how much glycogen is available in fresh meat.

Personally I recovered predominately on a high saturated fat diet similar to the Maasai pattern (I suppose a “what do I eat?” type of post is overdue). In my toolbox, however, were varying amounts of sugars and thyroid along the way (Cynoplus and Cynomel I no longer need, and my CO2 always falls somewhere between 29-32 mEq/L). Another kind of quirky thing about me is that the only carbohydrates I trust are those produced from animals. Namely those found in milk and honey. Maybe that is silly, maybe not. How much of the sugars we actually use after gut fermentation from milk is questionable. How much sugar? I have no idea but overall rather low, sometimes I put sucrose or honey in my coffee or tea sometimes I don’t. I like the occasional scoop of vanilla ice cream with bits of chocolate or if I’m feeling wild chocolate syrup. I also like cheesecake. I usually have absolutely no sweet cravings. But there were periods where I attempted to force feed myself large amounts of fruit. Virgin coconut oil was useful for slimming down at some points but refined was not. Sometimes I gently melt the coconut oil down and pour it over a bit of ice cream to make the chocolate syrup I make crispy.

My body temperatures are rock solid stable on high saturated fat 98.6-99 F. If I get a little wild with the sugars my body temperatures get wild as well which tends to agree with this.

On another note:

There is also another post I have in the pipes about mucin deficiency, which some have said is a lack of glucose in certain low carbohydrate promoting circles, whereas I believe it to be a deficiency of certain amino acids in the context of a diet that is high in muscle meats-namely glycine, which mucin is partly made up of.

Another topic I plan on writing about is methionine restriction. Obviously in some animals methionine restriction leads to increased lifespan, but I haven’t seen anything that would convince me that outright restriction in humans would have the same effect, and I think it is because there are certain species of gut bacteria that digest methionine. In fact there is some evidence to suggest that methionine deficiency causes gray hair. Anecdotally when I was in Santa Fe, NM at altitude there is a large vegetarian population there, and I noticed that a lot of young vegetarians 30-50 years old had rich gray hair.

Fermented dairy, lactic acid, and CLA

I consume a lot of full fat dairy. A good half of it—probably more—is fermented in some bacterial cocktail. In some places there has been resurgence in the idea of drinking lots of milk. I think anything coming from a cow is healthy. But some people believe that the lactic acid in fermented bacterial cocktails is harmful.

As well, people talk about how much milk the Maasai drank. Now the Maasai and other dairy herding cultures are healthy. Thriving off of cows and their milk and the products produced from their milk no doubt is a high saturated fat diet. I think dairy, as far as food sources go, is probably the best and safest food source. I think the rest of the cow is good, too. But with how bad fermented foods are supposed to be and limiting yourself to maybe two tablespoons of yogurt, well that sounds rather…

Thriving off of cows and their dairy is like extended breast feeding

Babies seem healthy to me and they seem to like breast milk. How dare a mother poison her baby with lactic acid producing bacteria (Martín et al., 2003).

I’m a big believer that a theory should—if it has any ounce of credibility—reflect what we see in reality. Most of the milk drank by the Maasai was fermented. There is a problem there. Given their good health and the fact they smoke a lot gives us a couple of angles to work from. No science required, just a little logic and common sense. First, the traditional Maasai were healthy. Second they smoked a lot. In modern culture we view smoking and/or nicotine as unhealthy, so if the Maasai have an unhealthy lifestyle factor then they must be protected by something in their diet (or some other factor). But we’ll avoid the complexity of those other factors for now and focus on the diet. So the Maasai smoked, and according to those who believe that lactic acid is harmful, that is also another risk factor for disaster.

The real question is: if lactic acid is harmful despite the fact that the lactic acid producing bacteria modulate endotoxin (Schiffrin, Rochat, Link-Amster, Aeschlimann, & Donnet-Hughes, 1995), and if smoking is harmful despite the fact that nicotine modulates endotoxin (Wittebole et al., 2007), well then…we have a big problem considering that most of the calories in the traditional Maasai diet are coming from fermented milk. These guys, according to some paradigms, are literally waiting to burst giant lactic acid secreting tumors out of their eye sockets, earholes and rectums. But they don’t. Of course, we could forever go down the road of different arguments, but really the simplest answer, and an answer that agrees with other traditional healthy cultures that ate fermented dairy, is simple: lactic acid is not harmful. Much like people who eat more saturated fat tend to be healthier. Yes, people who eat butter are healthier, faster, and stronger.

Of course, what is more interesting about fermented dairy is some of the special properties those bacteria provide us with. For example, Lactobacillus plantarum found in some fermented dairy products (but mostly in fermented plant concoctions) converts linoleic acid to CLA (Kishino, Ogawa, Yokozeki, & Shimizu, 2009; Ogawa et al., 2005). Of course, CLA is useful (Belury, 2002).

I don’t know. If you are eating a low PUFA diet and you are worried about PUFA, I kind of like the idea of a little flora mopping up what I can’t humanly avoid and turning it into something useful and probably healthful.

Bread and butter

I don’t think humans are idiots. That is a problem.

It’s a problem because people who pledge themselves to cult like eating habits assume humans are idiots.

I find the concerns surrounding wheat fascinating. When I come across a study like this one. It makes me think.

If you take away the butter what is left? The bread.

I find it interesting that right around the time butter, cream, and milk became unhealthful foods people started becoming allergic to their bread.

If a person discovers they feel like the plague after eating bread and they stop eating it and it helps that is good. If that same person and their friends say that wheat is a problem and that the entire human species is verging on mass suicide by eating wheat that is delusional.

Perhaps that person and their friends just need to eat more butter.

You don’t need to speculate what people ate eons ago, 100 to 200 years back is all that is really needed. People prepared and consumed foods in specific ways for a reason. Who eats bread without butter?

I don’t think humans (our species) are idiots. Insanity is doing the same thing over and over again and expecting different results. I don’t think humans (our species) are insane.

Ketosis: tissue unsaturation

This morning I came across this thread on ketosis and tissue unsaturation. I still watch the the Ray Peat forum because there are some curious people who ask interesting questions and they get smacked with wooden spoons. What is unfortunate is that those holding the spoon(s) are grossly mistaken.

This thread reminded me of a recent email exchange with Dr. Peat, in which he wrote the following in response to a brief summary I wrote on polyunsaturated fats, that summary is the basis for my recent post(s) on polyunsaturated fats:

That’s my interpretation too, it seems that we are perfectly adapted to a very warm planet with a lot of CO2 and with fats unsaturated according to the effects on structure and electronic behavior needed for special functions. I think our body temperature keeps our enzymes from evolving into the cold-blooded pattern, keeping us ready to handle the n-9 based fats when things improve.

Which brings me to the misunderstanding/misinterpretation some people have regarding PUFA. It is exogenous (dietary) polyunsaturated fats that are problematic born from the essential fatty acid doctrine. The body indeed produces it’s own unsaturated fatty acids such as those found in the brain for structure and special functions to the degree that they are needed when the body is fed appropriately.

Neonatal ketosis is crucial for proper neonate development.

Lactate and the brain: the neonate

Lactate-Balls-JPEG-1024x948Lactate seems to be able to produce C02 efficiently, at least in the context of the early postnatal period. What is interesting is that blood lactate doesn’t seem to be elevated. Yet it is being oxidized preferentially over glucose. Glucose seems to be being spared for specialized precursors. It is also interesting that lactate doesn’t seem to be going through the Cori cycle but straight to the Krebs (Medina, 1985), which is interesting because it might mean these early adaptive responses are not in the same stressful context such as working muscles? Much like producing ketones from ketogenic fatty acids is not stressful.

The dependence of cerebral energy metabolism upon glucose, 3-hydroxybutyrate, and lactate as fuel sources during the postnatal period was investigated. The brain of 6 day old suckling pups used very little glucose, but by the 15th postnatal day glucose was the major catabolite. Hydroxybutyrate was not a major brain fuel at either 6 or 15 days of age. Its utilization accounted for only 19% of the brain’s total energy needs at 15 days of age, even through blood ketone concentrations are near maximal at this time. Seventy percent of the cerebral metabolic requirements were met by lactate in animals aged 6 days. The major role played by lactate as a substrate for brain metabolism in young pups was not a result of abnormally elevated blood lactate concentrations. The slow catabolism of glucose in young brain can not be explained by low rates of influx or inadequate enzymatic capacity.

The maximum rates of lactate oxidation and lipogenesis from lactate by early-neonatal brain slices were considerably greater than those for utilization of glucose and 3-hydroxybutyrate at physiological concentrations. Lactate inhibited glucose utilization, but enhanced 3-hydroxybutyrate utilization. 3-Hydroxybutyrate inhibited lactate and glucose utilization. Glucose slightly inhibited oxidation of lactate and 3-hydroxybutyrate, but scarcely enhanced lipogenesis from these substrates.

Journal of neurochemistry, 112(4), 900–12. doi:10.1111/j.1471-4159.2009.06506.x

While the ultimate dependence of brain function on its energy supply is evident, how basic neuronal parameters and network activity respond to energy metabolism deviations is unresolved. The resting membrane potential (E(m)) and reversal potential of GABA-induced anionic currents (E(GABA)) are among the most fundamental parameters controlling neuronal excitability. However, alterations of E(m) and E(GABA) under conditions of metabolic stress are not sufficiently documented, although it is well known that metabolic crisis may lead to neuronal hyper-excitability and aberrant neuronal network activities. In this work, we show that in slices, availability of energy substrates determines whether GABA signaling displays an inhibitory or excitatory mode, both in neonatal neocortex and hippocampus. We demonstrate that in the neonatal brain, E(m) and E(GABA) strongly depend on composition of the energy substrate pool. Complementing glucose with ketone bodies, pyruvate or lactate resulted in a significant hyperpolarization of both E(m) and E(GABA), and induced a radical shift in the mode of GABAergic synaptic transmission towards network inhibition. Generation of giant depolarizing potentials, currently regarded as the hallmark of spontaneous neonatal network activity in vitro, was strongly inhibited both in neocortex and hippocampus in the energy substrate enriched solution. Based on these results we suggest the composition of the artificial cerebrospinal fluid, which bears a closer resemblance to the in vivo energy substrate pool. Our results suggest that energy deficits induce unfavorable changes in E(m) and E(GABA), leading to neuronal hyperactivity that may initiate a cascade of pathological events.

The role played by lactate as an energy substrate for the newborn rat during the early neonatal period was studied. Plasma lactate is mostly removed within the first 2 h after delivery, i.e. during the presuckling period. Lactate removal was enhanced by hyperoxia but strongly inhibited by hypoxia, showing a direct correlation with blood oxygen concentrations. Lactate was not converted into glucose during the presuckling period, gluconeogenesis being insignificant in these circumstances; instead it was rapidly oxidized through the tricarboxylic acid cycle. Likewise, lactate was significantly oxidized by brain slices from newborns at birth. At physiological concentrations, lactate oxidation by brain slices was 10- and 3-fold higher than that of glucose and 3-hydroxybutyrate, respectively. In the same circumstances, lipogenesis de novo from lactate was 2- and 5-fold higher than from glucose and 3-hydroxybutyrate, respectively. The results suggest that lactate is the main metabolic fuel for the brain during the early neonatal period.

The utilization of lactate, glucose, 3-hydroxybutyrate, and glutamine has been studied in isolated brain cells from early newborn rats. Isolated brain cells actively utilized these substrates, showing saturation at concentrations near physiological levels during the perinatal period. The rate of lactate utilization was 2.5-fold greater than that observed for glucose, 3-hydroxybutyrate, or glutamine, suggesting that lactate is the main metabolic substrate for the brain immediately after birth. The apparent Km for glucose utilization suggested that this process is limited by the activity of hexokinase. However, lactate, 3-hydroxybutyrate, and glutamine utilization seems to be limited by their transport through the plasma membrane. The presence of fatty acid-free bovine serum albumin (BSA) in the incubation medium significantly increased the rate of lipogenesis from lactate or 3-hydroxybutyrate, although this was balanced by the decrease in their rates of oxidation in the same circumstances. BSA did not affect the rate of glucose utilization. The effect of BSA was due not to the removal of free fatty acid, but possibly to the binding of long-chain acyl-CoA, resulting in the disinhibition of acetyl-CoA carboxylase and citrate carrier.

The metabolism of lactate in isolated cells from early neonatal rat brain has been studied. In these circumstances, lactate was mainly oxidized to CO2, although a significant portion was incorporated into lipids (78% sterols, 4% phosphatidylcholine, 2% phosphatidylethanolamine, and 1% phosphatidylserine). The rate of lactate incorporation into CO2 and lipids was higher than those found for glucose and 3-hydroxybutyrate. Lactate strongly inhibited glucose oxidation through the pyruvate dehydrogenase-catalyzed reaction and the tricarboxylic acid cycle while scarcely affecting glucose utilization by the pentose phosphate pathway. Lipogenesis from glucose was strongly inhibited by lactate without relevant changes in the rate of glycerol phosphate synthesis. These results suggest that lactate inhibits glucose utilization at the level of the pyruvate dehydrogenase-catalyzed reaction, which may be a mechanism to spare glucose for glycerol and NADPH synthesis. The effect of 3-hydroxybutyrate inhibiting lactate utilization only at high concentrations of 3-hydroxybutyrate suggests that before ketogenesis becomes active, lactate may be the major fuel for the neonatal brain. (-)-Hydroxycitrate and aminooxyacetate markedly inhibited lipogenesis from lactate, suggesting that the transfer of lactate carbons through the mitochondrial membrane is accomplished by the translocation of both citrate and N-acetylaspartate.

The isolated brains of 12 previable human fetuses obtained at 12 to 21 weeks’ gestation, were perfused through the interval carotid artery with glucose (3 mM) and/or DL-B-OH-butyrate (DL-BOHB), 4.5 MM, plus tracer quantities of either glucose-6-14C (G6-14C) or beta-OH-butyrate-3-14C (BOHB3-14C). Oxidative metabolism was demonstrated by serial collection of gaseous 14CO2 from the closed perfusion system, and from the recirculating medium. Glucose and BOHB were utilized at physiological rates as indicated (mean plus or minus SEM): G6-14C at 0.10 plus or minus 0.01 mumoles/min g brain (n equal 7) or 17.5 plus or minus 1.9 mumoles/min kg fetus; and BOHB3-14C at 0.16 plus or minus 0.05 mumoles/min g (n equal to 5) or 27.3 plus or minus 7.4 mumoles/min kg. Based on fetal weight, glucose metabolism by brain apparently accounted for about 1/3 of basal glucose utilization in the fetus. On a molar basis BOHB3-14C was taken up at 1.47 times the rate of G6-14C. Both BOHB3-14C and G6 14C were converted to 14CO2. The rate of BOHB3-14C conversion to 14CO2 was equal to its rate of consumption, and exceeded the conversion of glucose to CO2 because 45% of the G6-14C was incorporated into lactate-14C. Accordingly, both substrates support oxidative metabolism by brain; and BOHB is a major potential alternate fuel which can replace glucose early in human development.

Whole rat embryos were explanted at head-fold, late pre-somite stage (day 9.5 of gestation) and cultured in rat sera varyingly supplemented with glucose (3, 6, 9, or 12 mg/mL), D,L sodium beta-hydroxybutyrate (2, 4, 8, or 16 mM), or both (6 mg/mL D-glucose plus 8 mM beta-hydroxybutyrate). During 48 h culture, increasing glucose alone or beta-hydroxybutyrate alone effected growth retardation and faulty neural and extraneural organogenesis in dose-dependent fashion. Synergistic dysmorphogenic effects occurred when minimally teratogenic concentrations of glucose and beta-hydroxybutyrate were combined. Sera from diabetic animals containing somatomedin inhibitor bioactivity were also able to produce growth retardation and major developmental lesions in presence of amounts of glucose and ketones which of themselves were not teratogenic. Thus, aberrant fuels and fuel-related products can impair growth and organogenesis in early post-implantation embryo. Such fuel-mediated teratogenesis may be multifactorial and include possibilities for synergistic and additive interactions.

Polyunsaturated fats: why are they harmful? Part I

Some people in nutritional science are aware that the polyunsaturated fats such as those found in industrial vegetable oils can be harmful. But few people that I’ve read seem to illustrate why PUFA are harmful in a way that gives a logical understanding. When someone says something is harmful they are merely stating something. It does not mean they actually understand the “why”. A person might read a study and the study might be correct and that person may regurgitate what was in the study. Though the person may be informed they lack the visual pictures painted in the mind that helps to form a basis from which other conclusions can be drawn. In other words, they have no real understanding. That phenomenon is rampant in nutritional science. From a practical standpoint that approach may work, but for a person who is in a complicated situation or trying to understand more than that, the approach is limited, and taking shots in the dark could have negative consequences.

In order to understand the world around us, we cannot just memorize facts and connect dots. It leads to superficial understanding.

Many people have said that polyunsaturated fats are harmful and have provided evidence for why by putting together pieces of their effects in different contexts. But that does nothing in the end to help us to predict upstream and downstream effects, in that approach we are without prediction power for making rational choices.

In your body you have different lipid-like hormones and nutrients. A lot of these hormones and nutrients are unsaturated. In other words, they resemble the polyunsaturated fatty acids. In a body that doesn’t have bottles of corn oil floating around, these unsaturated hormones and nutrients bind to the cells as they should, like putting a key into a keyhole. Though that is a rather mechanical way of thinking about it, the analogy is useful. When you consume polyunsaturated fats they in effect bind to the same places your hormones would normally bind. As long as the body remains fairly unstressed this poses minimal problems in the short term.

Under stress, however, the body releases the protective hormones. If the body is saturated with the polyunsaturated fats, the unsaturated hormones can no longer bind. Over time, the body can no longer respond to stress efficiently because the protective hormones can no longer function, in effect, the polyunsaturated fats are mimicking the binding of unsaturated hormones blocking the protective hormones from functioning.

Over time, as we age, we gradually lose the ability to respond to stress because of this process. In other words, resistance to stress is the ability to respond to stress efficiently. As we lose the efficiency to respond to stress, we age because we are unable to repair the damage caused by stress. In other words, aging is a feature of the body not being able to respond to stress efficiently and completely. Stasis must shift to maintain balance. It is the shifting process that can be problematic.

In the cell there is an organelle called the peroxisome. The peroxisomes break down lipid like substances or xenobiotic compounds. In other words, they protect the cell from foreign compounds. That seems to be one of their primary functions.

What is interesting here is that the mitochondria work in a similar parallel when they metabolize oxygen.

I had known from prior research that the polyunsaturated fats cause problems with cellular respiration by reducing the efficiency of the mitochondria, thus overall efficiency of the cell, in a sense turning the mitochondria into “mush”. Different fuel substrates have differing efficiency, so I needed something more, something that pointed to a problem with the nature of polyunsaturated fats themselves.

When a cell is exposed to PUFA the peroxisomes proliferate or increase in number rapidly. Peroxisomes are especially sensitive to the unsaturated fatty acids. In the laboratory, fish oil is commonly used in their study. Interestingly, the saturated fats do not cause proliferation in most cases. It is also interesting that cholesterol lowering drugs also cause peroxisome proliferation. Remember: peroxisomes proliferate when exposed to harmful substances.

So the cells can, to some extent, protect themselves from PUFA by breaking them down. Given that, why can’t we consume PUFA with a clear conscious? And why do some people seem to be able to eat more than others?

Part 2 shortly.

Lactate and the brain

The lactate shuttle theory has been around for a couple of decades. Essentially, it is associated with the idea that the brain prefers lactate as an energy substrate, but lactate shuttle theory is actually describing a (proposed) mechanism, not the implications. I had been aware of the idea, but was not sure of the context of functionality. From some prior research I had found that the brain stores glycogen.

Peter has a brief post on this.

You always find a high concentration of GLUTx transporters in high energy organs. Having a high concentration of GLUTx transporters points to earlier times and to some interesting ideas.

The fact that ROS (reactive oxygen species) from glucose causes problems in the brain has always seemed strange to me given the common idea that the brain prefers glucose. Bypassing glucose metabolism with either fructose 1,6-bisphosphate or ketones has anticonvulsant activity. Given the composition of the fatty acids in the brain ROS seems like a really really bad idea, and it is probably the reason that if ROS is reduced things start working better.

When I started researching neonatal ketosis, I saw that besides the elevated ketones in neonates, lactate was also elevated. Ketones and lactate seem to be essential for a developing brain. Here are some papers on lactate below that can be tied in with the neonatal ketosis post.

So given this, the question is why? Why in neonates are ketones and lactate elevated? Does the status of a neonate represent an optimal status that we as adults should mimic, or is the status of the neonate a contextual adaptation? I have my own ideas as to why. What are some of your thoughts?

Saturated free fatty acids, polyunsaturated free fatty acids

http://www.raypeatforum.com/forum/viewtopic.php?f=37&t=2862&start=40#p34670

It’s something I don’t really understand. It’s like saying, you have a diet of higher fat that is not conducive to high metabolic rate, but you add in a few hormones and it’s fixed. But if the fat diet provided enough energy, why do these hormones naturally decline in the first place? How can hormones compensate for an energy problem?

I think Edward must have a good explanation for this, because his posts have hinted about good thyroid not being incompatible with higher fat ratio.

The underlying explanation is that there is a difference between saturated free fatty acids and polyunsaturated free fatty acids. Essentially you self-induce mitochondrial diseases with polyunsaturated free fatty acids; you can’t do that with saturated free fatty acids. There is a longer post here but sadly no time. Sometime after the 16th.

Governing dynamics

Not much anymore do I entertain the idea that there is template diet for people to eat and be healthy on (cough… butter). In the end what is a good diet usually follows some sort of common sense. Of course common sense is a hard commodity to come by for most that have grown up in Western culture where food is abundant and survival that counts on one finding food is obsolete.

More so, I find that people who are interested in “nutrition” are unfortunately some of the sickest people I have come to know in my life, not only do they suffer from day-to-day with choosing foods to eat, but they also suffer with varying degrees of the opposite of cognitive clarity. As Peter writes in so many words there are in fact very few normal people…

Of course this is not some semantic logic designed to say that common sense would be this or that, and if you don’t agree with my common sense then you lack common sense, but rather, common sense is: the ability to think and reason on your own.

There are an abundance of brilliant and free-thinking people in the world. And for every one of those people there are a google of people claiming that the brilliant person they defend (for whatever reason) is correct, not just correct in one or two things but most things; most of the time I find this defense to be for self-confirmation rather than anything remotely resembling something of noble virtue.

People have this idea that if someone is correct about one thing and that one thing happens to impact their life for the better, then the brilliant person who discovered a morsel of applicable truth, must by extension then be correct about other things. Perhaps.

Perhaps not. And it is the perhaps not that people seem to have trouble with, and I postulate that this problem stems from the concept of sin and perfection from Christendom. People have a really hard time accepting that brilliance comes in short stories not novels. If a man is right about one thing, and wrong about another thing, then that right thing will be questioned. People seem to have a hard time excepting the paradox that reason can give you a truth but that same reason (framework) can lead to very wrong conclusions.

Where you find a brilliant person with a brilliant idea, you will find googles of people in some form or another twisting that brilliant idea, into a dogma. I always found that rude. But while rude, this is what Max Weber the sociologist observed when dogmas create dilemmas. Worse, those people defend the progenitor of the idea as if they are soldiers of some noble cause, some personal friend. I’ve always found that rude as well and more than slightly ignorant.

Perhaps it is time that we allow governing dynamics a chance to take over. Nash and Smith both understood this concept, one mathematically minded and the latter economically minded.

Experiences at altitude: part 1

These initial posts will serve as observations and note my experiences, speculation and explanatory ideas will come later. I will write what I can when I can as I’m without regular Internet access still.

Earlier this year I went to Santa Fe, New Mexico for a little over 3 months. Santa Fe is close to 7000 feet above sea level and the climate is dry. The evenings can be cool when there is no cloud cover and the days during the summer time can be miserably hot; it is quite easy to sunburn.

As someone who is hyperaware enough to feel my own cells turnover I was interested in the effects that might occur as I settled in my new environment.

When I was a child I suffered with severe asthma, one of things I learned to do when I had trouble breathing was to pull the covers over my head and breathe the warm air. That always seemed to help. Sometimes I would wake up in the morning completely under the covers as if I had been under there all night. I don’t know if I was under there all night, but obviously I was pulling them over my head in my sleep as well. I was a brother of the naked mole rat. (Except that butter has a profoundly powerful effect at relaxing the lungs, lowers lipid peroxidation of the PUFA sort and eosinophil counts… better then living underground.)

I have not had asthma symptoms for a long time, not being able to breathe especially as a child puts an interesting perspective on the rest of your life and you realize very quickly what gases are important.

Prior to my arrival in Santa Fe the only times I’ve had trouble with breathing since childhood was during the period I was experimenting with Aspirin and when I transitioned from a carbohydrate restricted diet to a unrestricted one. That transition had me in the hospital hooked up to a breathing machine with only the best steroids.

When I arrived at altitude I was not sure what to expect nor had expectations but when I got off the plane the air was clear and crisp and I didn’t find it difficult to breathe or anything of that nature. For the first couple weeks if I was doing something harder than walking I would pant but when I would squat for singles or doubles I would not have the panting. Mostly because singles and doubles avoid the glycolytic metabolic pathways. I did not have regular gym access for a while so initially I was sedentary.

I had an irregular sleep schedule from the time change (Germany). I’ve never had what you’d consider a normal sleep schedule. I’ve always been somewhat of a night owl, o.k. more than just a night owl, more like a burning the midnight oil till morning person and sleep when I’m tired.

I’ve never been a person to believe in theoretical nutrition and I view sleep much the same way. I sleep when I’m tired and am awake when I’m not. I never really viewed a certain sleep time as healthful or unhealthful—just that poor sleep quality is a marker for poor health—in other words when tired if you sleep and wake up rested that is good, and if you are tired and can’t sleep and don’t feel rested then that is not good. The sleeping patterns of traditionals were quite irregular and they were seemingly healthy so I never gave that theory, the theory of some sleep at some specific time of the day any credibility.

Anyhow the latter is what happened at altitude. The bad sleep. I could not sleep normally, and additionally I would have trouble breathing when I would try to sleep. That went on the entire time I was there. There wasn’t a single thing I tried that worked for more than a day or two. And when I would try something that seemed to work it would its effectiveness like clockwork about 2 days later.

After about 2 or 3 weeks I begin to have joint pain, my knees especially started to sound like there was sand inside of them every time I would bend at the knees. This continued on till I left and the only thing that seemed to help was dairy, butter seemed to be the most effective. Indeed most high altitude cultures are dairy based.

O.k. a page or so for now, will continue on later.

Oh, almost forgot my typing tests declined as well.

This post will be updated with references as soon as I have regular access to databases again.

Experiences at altitude

I’ve just come back down from altitude after being at roughly 2100m for close to 3 months. I want to expand on this experience a lot actually as there were a lot of things that I noticed while at altitude. I don’t have time at the moment to write as I am in between countries but this is the biggest topic on my mind at the moment. Once I get settled (and a regular Internet connection) this blog will be more regular. Cheers.

The complaints have been increasing and as administrator I have made the decision to close the doors of the forum to you

You know your doing something right when the folks at the Ray Peat forum ban you.

I received this message from Charlie the administrator (the funny thing about people who claim to be “open-minded”, they always prefix their statements of action with authoritarian language i.e. “as administrator”):

There have been many complaints about you, particularly the number of posts in opposition to Ray Peat and that those type of discussions should be taken elsewhere as this is not the proper forum to continuously initiate such discussion. The forum was created specifically for people to come and discuss the work of Ray Peat – not to debate it, to discuss it, share insights about it and work together to understand it while gaining their health through the practical use of his information. The complaints have been increasing and as administrator I have made the decision to close the doors of the forum to you.

I think accountability is a good thing:

Hi Charlie, receiving complaints does not justify closing the doors on me. You know that I have contributed in depth information to this forum. Further I have the reputation points as evidence that what I write is useful or at least that there is some agreement. I post the the studies in the appropriate sub forum which the description says “A place to post and discuss scientific studies”, I only have ever stated that I disagree with Dr. Peat on some things, and those are more so his abstract concepts, and I am entitled to that opinion especially as a Veteran. It’s not like I don’t think the thyroid isn’t important. So I disagree, and then a user challenges and asks for evidence and I provide evidence which is crystal clear and do not engage in the childish behavior. So complaints about evidence? So what? People who complain about evidence are people who are stuck in dogma.

There is a difference between debates and discussion, discussion is evidence based, debates like in the recent thread are more of personal attacks rather then objective. I don’t participate in that. I just flag it.

Further my points of disagreement have not changed since I became a member of this forum. And like I said most of that has to do with abstract and theoretical implications.

When looking at science you cannot reject evidence, and evidence to the contrary of something does not mean evidence against it necessarily, what it does mean when results conflict is that there is another process at play or even a relationship.

And in the case of thyroid and ketones there is evidence for a relationship that goes back several decades. I’m not really willing to ignore that are you? I want to know the full functionality of the endocrine system.

You can dislike me and my style and so can the users on this forum, but really banning me only takes away from the forum. It’s all too convenient to silence someone who wants to think a little more thoroughly and carefully about things. And then you become no different from the rest of them. It’s not like I spout without presenting a study, how many studies have I provided on this forum for people to download? Hmm.

As I’ve said I’m looking for truth and ways to tie in Dr. Peat’s work with recent evidence. Making ALL your conclusions off of old studies is like saying the earth is flat and rejecting the pictures sent from space showing perfectly clearly the Earth is indeed round.

It’s fine if you want to ban me, ban me, just give me a few days to download the forum and I won’t post anything.

If you change your mind let me know, I will still continue to contribute and still will maintain the same rational and even keeled response I always write. It’s not a pissing contest for me that should be clear for sure through everything I’ve written. Most people argue at least I provide something more to go on than just an opinion.

Also your gums, it’s a sign of inefficient respiration.

Edward

And after I didn’t receive any responses, I responded once more:

Charlie, how about this? What if instead of posting the studies that conflict with Dr. Peat on the “Scientific Studies” portion of the forum I instead post them in the “Ray Peat Debate Forum”, and then the studies that tend to agree with Dr. Peat I post in the “Scientific Studies” portion of the forum. Although I feel that is filtering, it could be a reasonable compromise?

I’m completely willing to post stuff to different parts of the forum if you think it would help.

Edward

Quite frankly this came as a surprise for me. I had contributed a significant amount of time and effort to the forum and I know that my advice has come in handy for several people. I have always given citations when information I provided was counter intuitive.

It becomes apparent after spending a great deal of time on a forum like that the the people there are sick and the evidence of that manifests in their writing. Quite a few people for being healthy seem quite irate. And that is fine. I wish them the best. I made a few good friends while I was on there.

Using typing speed and accuracy to measure brain function

I’ve been playing with typing tests for about a year as a way to measure my brain function. I think that typing is a unique test because it uses parts of the brain that I consider important. The hipppocampus and cerebellum.

The cerebellum is known for it’s involvement in motor control and the hippocampus in short and long term memory and spacial awareness. The deterioration of these areas of the brain also happen to be involved in things like dementia and thyroid malfunction.

Some things I’ve noticed. Butter, chocolate, cigarettes, thyroid hormone (or thyroid supporting substances), and fatty cuts of pork (probably the glycine, although I haven’t tested with gelatin) tends to improve both my speed and accuracy. Significantly.

It seems that all these substances seem to have immediate boosting effects. Pork fat seems to have a longer lasting effect in that you don’t seem to need to eat it every day to maintain a result. Pork seems to outperform butter in the lasting effect, and chocolate seems to be like octane. Stearic acid has many neuroprotective effects which high fat chocolate is rich in. Butter seems to have more a calming effect (reduced stress?) which allows better brain function.

Cigarettes seem to work best on a high fat diet where complex I is fairly inactive anyway.

My guess besides having favorable affects on mitochondria is that all these substances (aside from the pork) also seem to modulate LPS (endotoxin) in appropriate ways. That does not necessarily mean decreasing or lowering LPS but rather modulating it in favorable ways. LPS seems to be more complicated than a more or less scenario.

There is some room in here for tight junctions and calcium channeling but other things to do at the moment.

Bleszynski’s human-to-primate social regression

Stan Bleszynski has a series of posts on human-to-primate social regression. I like the gist mostly because I pull from the same hat. Stan asked are autistics more human? I wondered the same thing when I was thinking about Göbekli Tepe and ketones. I think autistics are more human. I think that at one point those characteristics were more prevalent. A few quotes (not in any particular order), the other points should be fairly obvious to social retards: Continue reading
