i definitely have a diverse microbiome but what i eat filters that down as well

but intolerances to a specific set of common vegetable proteins found in many foods that the EU approves for sale is not quite the same because it's my immune system literally flagging the food as a pathogen and this triggering antibodies that are coded for proteins that are part of my own body and thus leading to anaphylaxis

definitely helps to get the microbiome in better shape though... this is why i have been switching up my diet, i've added some seafood, peas, beans, carrot, potato, i stopped drinking red wines that seem to be contaminated with some kind of plant protein that gives me a really upset intestines

and i also now have a cat, who is transiting all kinds of new microbes into my gut, possibly helping reassert balance of some of them, i'm sure... and i don't feed him stuff that isn't actually mainly meat... pretty much all of it is pasteurised shredded fish and beef and similar...i remember a couple of years ago those pasteurised sachet bag foods from brands like Whiskas and i looked at the "meat" in it and i didn't see meat i saw textured vegetable protein and the cat did not like eating the solid, only the gravy with it... the stuff i feed now i can see it's actually meat
