I believe the case that man's evolution has been shaped by fire.
The fire which is used to cook and prepare meals too.
We don't have the muscle-stomach of a chicken, eating a couple of stones to grind the grains inside our bellies.
So we grind it with tools, we remove the high-fibre parts which also contain most of the toxins which a plant uses to defend itself against plant/seed eaters.
We cultivated grains which contain less toxins, less fibre and more starch.
We cook and bake flour, we ferment the dough (at least we used to) all in an effort to have less toxic substances and more available energy inside the finished food.
Beans, legumes in general, soy, all very poisonous if not well cooked.
Soy in particular is a modern food besides fermented Asian soy sauce. Soy today requires heavy processing, not merely some cooking procedure, to make it somewhat eatable.
Sickness and weakness is popular and being sold as the new healthy. In all areas of life, including modern dietary recommendations.
