Wow! Thanks for this information overkees !
I should take those articles of Ray Peat more seriously, this gelatine is something I've never read anywhere, but seems to be so true.
Maybe a little bit too early to judge on my own experiences. But it really feels like animal protein falls more lightly on the body.
And the theory sounds very solid from a natural perspective:
Ray Peat wrote:Gelatin (the cooked form of collagen) makes up about 50% of the protein in an animal.
By the way, I've been studying a little bit about it. And it is structual similar to acetic acid.
In fact, on other name of for glycine is aminoacetic acid.
Ther is quite an apple cider vinegar hype going on at some places on the internet.
I understood that panacea believes that 99% of the hypes on the internet are all "placebo" or whatever, but I don't really believe in that.
Those hypes may not be that the ultimate solutions, but I think it provides information about how people react on certain food/substances.
Apple cider vinegar clearly seems to have positive effects on many people.
It is thought that acetic acid is the main reason of those positive effects.
I guess that a glycine rich diet could be a more natural way of getting the results of using apple cider vinegar.
By the way, to lay some connection with my old obsession PGD2.
Many substances similar to acetic acid have shown to be potent CRTH2 receptor antogonist. (google: acetic acid CRTH2)
PGD2 binds to the CRTH2 receptor.
First I thought that acetic acid would give an imbalanced response as it inhibits only one thing of the PGD2 pathway.
But now I think, maybe this is completely natural. Our body may be evolved having this CRTH2 pathway partly blocked by the cause of glycine in our diet.
