@DozingAnt “It truly is surprising how popular protein powders are. The tryptophan topic always fascinates me because Dr. Peat’s articles on methionine restriction and the phosphate to calcium ratio seem to be major pillars, along with the PUFA elimination, for attaining robust health. ”
Here is are a couple more for you on why I avoid excess tryptophan Ant…
“When rats were fed a diet completely lacking tryptophan for a short period, or a diet containing only one fourth of the “normal” amount for a more prolonged period, the results were surprising: They kept the ability to reproduce up to the age of 36 months (versus 17 months for the rats on the usual diet), and both their average longevity and their maximum longevity increased significantly. They looked and acted like younger rats. (A methionine-poor diet also has dramatic longevity-increasing effects.)” -Ray Peat
“Whey has been promoted as a protein supplement, but it contains a much higher proportion of tryptophan than milk does. Cheese (milk with the whey removed) contains even less tryptophan. Some people have been encouraged to eat only the whites of eggs, “to avoid cholesterol,” but the egg albumin is disproportionately rich in tryptophan.” -Ray Peat
