those are concerns that I believe were originally raised in the 1950s and 1960s based on rat studies and that's exactly the case that that when they gave rats a high methionine diet and they limited glycine they saw a lifespan restriction they saw they died earlier and then when they supplement when they took them a thiamine out they said oh they live longer and then people stopped you know and they think ah see rats live longer when you limit their Metheny and therefore we should never eat meat and we should all be skinny and never have you know any anabolic processes doesn't make any sense right we would never have gotten at this point in evolution by avoiding Metheny and then the third experiment is the one that people often forget about but is the most important experiment which is where they added glycine in to the diets and they saw lifespan extension because it was more about the Metheny and glycine ratio then the actual burden of methionine
