"Glucose Loading" protocol, a la Dr Stephens - A Critique
-
I did a deep dive in to why I was getting headaches from too much sugary foods away from meals
Would you try pure dextrose sugary foods as a crosscheck to your experiences with sugary sucrose (50% fructose) foods?
(USA Smarties, maybe marshmallows if you can find good ones not loaded with phosphates, homemade dextrose-only muffins, gummi bears, cakes etc.)

Good question. It would be a moot point as the glucose itself is found to push tryptophan in the bloodstream. In fact I was reminded of my issues, as people were describing problems on the protocol of glucose, so I think I may have found the problem.
It also gave me diarrhea. I’d be interested to know if people are getting digestive problems on the protocol… of course they may call it a herx reaction or detox

@TexugoDoMel said in "Glucose Loading" protocol, a la Dr Stephens - A Critique:
Carbohydrates alone raise serotonin through the effect that insulin has on amino acids, increasing the proportion of tryptophan in the blood in relation to other amino acids (which insulin removes from the blood). It would basically be the same if you supplemented tryptophan alone.
But although it seems that carbohydrates are a problem in this case, the real problem is the ratio of amino acids. If you consumed the same amount of sucrose but added some gelatin/collagen or even BCAAs, this effect on increasing serotonin would be abolished. This is even the basis for the “acute serotonin depletion” technique
John D. Fernstrom has several studies on amino acids ratio and serotonin
When plasma tryptophan is elevated by the injection of tryptophan or insulin, or by the consumption of carbohydrates, brain tryptophan and serotonin also rise; however, when even larger elevations of plasma tryptophan are produced by the ingestion of protein-containing diets, brain tryptophan and serotonin do not change. The main determinant of brain tryptophan and serotonin concentrations does not appear to be plasma tryptophan alone, but the ratio of this amino acid to other plasma neutral amino acids (that is, tyrosine, phenylalanine, leucine, isoleucine, and valine) that compete with it for uptake into the brain.

That carbohydrates raise serotonin as a matter of certainty is dependent on the idea that carbohydrates always raise insulin, which I would say isn't always the case.
An insulin response isn't triggered when blood sugar doesn't stay high enough about thirty minutes (this varies and I am just throwing a number in here) after a meal. When the body can absorb and metabolize easily a huge influx of blood sugar from a high carb meal (especially of high glycemic index), blood sugar level is not raised to a high level that triggers insulin to be secreted. So insulin levels can remain low, and this won't cause serotonin levels to become high.
Friedman's test subjects may be representative of the population that is metabolically disposed to produced a large amount of insulin, but it does not represent a population of healthy people with good metabolic health, which have good control of blood sugar levels, where their blood sugar are not easily raised to where an insulin is secreted as abundantly to raise insulin levels that cause serotonin to be released.

I agree, Ray has stated on multiple occasions that to reduce the insulin spike from protein, to consume a sugar item approximately 15 minutes before the meal (meal also well balanced with carbs).
So I would agree also that certain conditions be met for sugar to raise insulin, or indeed be problematic as I’ve described. I would assume Clearly there’s more to the mechanism than is being described here. Also, I don’t know that insulin itself is the only problem. When I did some “high insulin” experiments (eating the most “insulinergic” foods recorded in databases), I felt great. Ray himself has implied insulin can be good if I remember correctly (also if I remember Georgi correctly).
I’d like to know the mechanisms of action for excess sugar raising serotonin more specifically.

Yes. I have been getting rough digestive issues for a couple of days after every increase in dextrose and have written on this in the other thread.
I've only just read Limon9's 2022 post and the table in
Yokogoshi H, Wurtman RJ. Meal composition and plasma amino acid ratios: effect of various proteins or carbohydrates, and of various protein concentrations. Metabolism. 1986 Sep;35(9):837-42.
Dextrose really more than doubled rat plasma tryptophan. And especially Leucine really tanked to about half. When there was no dietary protein.There are two valuable approaches here I see opening up:
- Take gelatine or BCAAs together with each dextrose serving or pay heed to being "loaded-up" all day with sufficient dietary protein in digestion.
- Yerrag's mentioning of lowering the insuline-spike from carbohydrates/sucrose/dextrose by facilitating cellular uptake and metabolic usage of glucose.
This can underscore the importance of:
...2.1) Gradual increasing of dextrose servings in accordance to the increase of metabolic glucose usability.
...2.2) Cofactors for cellular glucose uptake and sparing of insuline. E.g. potassium and chloride.
I'm already doing 2.2) but haven't been able to eat my usual amounts of meat recently.
I will try a 1000mg capsule BCAAs with every serving.
Oddly, however, and despite preexisting serotonin issues of mine, when I had tried these BCAAs capsules before they had made my GI system much worse instead of better.
Are BCAAs and glucose perhaps significantly reciprocal in their requirement?
I know that gelatine/collagen/glycine and also AAs like taurine lower blood glucose and can effect stress reactions, which stands in stark contrast to what they ought to bring about.PS:
a) How much BCAA or gelatine do you reckon are necessary to compensate the AA-shift by every xx grams of dextrose (if there were no other dietary protein)?
b) Perhaps I'm being too dumb atm to see the mechanism behind these extracellular amino-acid shifts. Do they happen because the non-tryptophan amino acids are being "put to good use" by insuline and/or carbohydrates? -

Honestly, if one's liver function is so compromised they need to avoid fructose, then they should definitely be breaking up an already necessarily low protein intake, to multiple meals throughout the day... almost down to a few bites every few hours maybe.
let us know how it goes

A keyword search with the DocSearch+ app in my phone shows much of what Peat has to say to say about insulin to be negative.
Perhaps you recalled Ray in his March 2021 newsletter saying this:
Many years ago Gaetan Jasmin (1956, 1968)
showed that low blood glucose intensifies abnor-
mal inflammatory reactions, and that increasing
blood glucose minimizes dangerous anaphylactoid
reactions. It’s the oxidation of glucose (producing
carbon dioxide), which is favored by warmth and
the right amount of insulin, that can prevent
inflammation (Razavi Nematollahi, et al., 2009;Also:
W. Adamkiewicz showed that reducing blood
glucose with insulin greatly intensified aller-
gic reactions, while increasing blood glucose
prevented deadly anaphylaxis, but weakened
resistance to infection. Energy metabolism
governs the effectiveness of the immune
process, including the avoidance of autoim-
munity (Gaber, et al., 2017).
Metabolic energy is involved in every
aspect of the covid infection, but that has been
denied or ignored because of a traditional,
ideological understanding of immunity.Sep. 2021 Ray Peat Newsletter
He qualified with "the right amount of insulin (first citation)" which I believe to not be the case when blood sugar is not well-regulated, with yoyos from high to low.
Although I have not heard Ray consider insulin as a stress hormone, I would consider it to be such, and the less of it the better although I would be hesitant to be deprived of it, in an emergency situation. But that is the nature of stress hormones, to be there in emergencies and only in emergencies, and not to be availed of regularly.
Re: serotonin and insulin, a search result:
At puberty, there is a sudden increase in the
incidence of depression, especially in girls.
Increased adrenaline, like increased cortisol, is a
feature of depression, stress, and inflammation;
mobilizing fats, it can become part of a vicious
circle, in which free fatty acids cause insulin resis-
tance, activating the stress reactions. Increased
serotonin is a feature of inflammation, shock,
stress, and depression, and, like histamine, is tied
very closely to estrogen's effects.Feb 2001 Ray Peat Newsletter

@LetTheRedeemed Have you tried salt for the headaches?
-
@Janelle525 yes. I’m definitely at the pinnacle of my salt intake, haha.
I lowered my sugar consumption, or at least balanced it with spreading out my protein intake, and the headaches went away. That was a while ago. And I definitely still consume quite a bit of sugar: several sodas/juice/sweat teas per day, plus spoonfuls of honey with milk, and ice cream. I’ve definitely found my max sugar capacity
