PCC Sound Consumer | Paleolithic diets: Should we eat like our ancestors?
This is by Stephan Guyenet of Whole Health Source, writing for his local grocery co-op. I just think it's clear, logical, well argued, and very persuasive. Does not smell of Woo, hype, or sales pitch. I'll send this to a few interested people I know.
Note: Dr. Guyenet is not orthodox paleo / primal himself, mainly that he eats some grains and doesn't think meat is quite as awesome as we do, but thinks it's a good overall paradigm and worth trying out.
