Cooking food is an adaptive behavior that reduces disease and alters nutrition. It was the gradual exploitation of nature for the domestication of monocultural, industrial agriculture with supply chain processing that makes for most food modern people eat including "convenience" foods. This division of labor, whether organic farmer or pseudo-family megafarm, is what renders individual hunter-gathering a waste of time. From this over-abundance of calories and protein, it could support more robust bodies and larger brains, but it's a moot point considering obesity and the inevitability of the technological singularity.
