Yes, eliminate the processed and refined foods, I agree.
But... we were eating cooked meat waaaaaaaay before KFC commercials.
Let's look at the facts:
(from "Raw deal?"
http://www.theomnivore.com/Raw_food.html)
"Let's start with the contention that man has not evolved to eat cooked foods: an extensive review conducted back in the eighties, which examined all the available archaeological evidence, concluded that humankind's controlled use of fire began somewhere between 230,000 and 400,000 years ago.(2) New research reported in a recent issue of Nature suggests this figure may in fact be closer to 800,000 years ago.(3) Regardless of who's right, humans have been cooking food for hundreds of thousands of years.
Rather than transform our foods into harmful, immune-assailing toxins, cooking can actually increase the availability of certain nutrients. The carotenoids in foods like carrots and tomatoes, for example, become far more bioavailable after cooking. Cooking can also destroy nasty microbes lurking in the foods we are about to eat.
As for raw fooders trying to hi-jack the evolutionary-correct diet argument, hominids have been eating meat for over two-and-a-half million years--and there is plenty of evidence to back this up, in the form of skeletal radioisotope analyses, findings of stone tools and cut marks on animal skeletons, observations of recent hunter-gatherers, and an examination of human nutritional requirements (vitamin B12 for example, can only be obtained in nature from animal foods--they didn't have health food stores back in the Paleolithic era).
In contrast, the evidence showing that Stone-Age man sat on the savanna mixing up wheat grass chasers in his Breville juicer, while occasionally glancing over at his Sunbeam dehydrator to see how the dried apricot halves were coming along, is non-existent."
