You're making very strong claims based around broad trends in genetics for a process that isn't entirely genetic. The society that is choosing what to eat and how to prepare it is doing so based on their own set of axioms, not pure genetic biology.
The argument is probabilistic, itβs not required that food seeking behaviours are entirely genetic for it to go through. As long as food seeking behaviours and/or preferences are to some degree genetically determined, then the argument is sound and valid.
If I can safely discount all human behavior through history, then I can also assume that the behavioral changes you are espousing are equally non-relevant. Either human behavior can be a greater driver than genetic probability or it can't.
