Cooked

We get twice as much energy from eating a cooked potato as from a raw one.

This according to Herman Pontzer, Duke U. evolutionary anthropologist and internationally recognized researcher in human energetics.

In a 1999 study of over three hundred men and women following raw food diets of varying strictness, participants had a hard time maintaining healthy weight, women often stopped ovulating, and some men reported loss of libido.

"Every culture ever recorded, from the tropics to the Arctic, cooks their food," says Pontzer.

We're fire adapted.
