Is there any evidence that humans need some raw food to be maximally healthy? Or can we eat a 100% cooked food? In other words, assuming a cooked diet that is otherwise very healthy (and that answers all of the body's vitamin/mineral needs), is there any reason to think there is something else (e.g., digestive enzymes, un-denatured proteins) in raw food that we need?
P.S. I know all about the wonders of raw milk vs. pasteurized milk, but I'd like to put that aside since dairy is by no means required for human health.
Second related question:
Assuming fruit is identified as something that makes sense to eat raw (because it's palatable and easy to digest raw or because polyphenols are degraded during cooking, or for another reason), is there any evidence that humans need to eat anything other than fruit (e.g., vegetables, nuts, meat) raw?
