About 5
million years ago we went from tree dwelling apes with a high percentage
of fruit for calories through a transition to the peak predator on the
planet spread somewhere across that next 5 million years, to a herding
species under 50K years ago who ate a much less varied list of prey
animals to a farming species under 20K years ago who ate far more grain
than was good for us, to an industrial junk food species in the last
couple of centuries. Since it takes around 5 million years of steady
diet to evolve it to optimal and humans have not had that, humans don't
have any optimal diet. But the closest we have to it is hunter gatherer
cultures who eat varied lean hunted meats, who walk several hours per
day and who eat wildly varying plant foods across the year.

I've read many accounts that hunter gatherers spent less than 20 hr./wk
in foraging food. I'm sure some spent more. Some spent less. Where does
this 50K for herding come from? It's news to me. 10K ago is the usual
number given for the beginning of agriculture. The industrial revolution
started about 300 years ago, but junk food made from ubiquitous white,
wheat flour is only about a century old and only wide spread in the last
50 years.

I forgot to mention Le Roque St. Christoph, continuously occupied for
50,000 years!
