Life is a struggle. If you don't eat sufficient energy, you die. This has
nothing to do with diet choice - it's called physics. Insufficient energy
content will kill you quicker than any other form of nutritional deficiency.
This remains true irrespective of whether food is abundant or not.
Excepting predation, all animal populations grow in number to the limit of
their food supply. Any initial state of abundance can only be temporary.

If cooking offers a survival advantage, its a foolish person who ignores it.

It is better to be alive, in less than optimum health, than to be dead because
of our refusal to compromise our diet beliefs.
