an interesting article from the current issue of "Harvard Magazine" that discusses America's dietary habits, including a short discussion of Wrangham's research indicating that humans are naturally adapted to a cooked food diet: http://www.harvard-magazine.com/on-line/050465.html and here's a supporting/background article on Wrangham's research from an earlier issue: http://www.harvardmagazine.com/on-line/1100110.html PS Some raw vegan advocates have attacked Wrangham's research -- even though it appears that they haven't even read the published journal articles! This intellectually dishonest practice is standard behavior for some raw vegan promoters, in particular the raw vegan pseudoscience fakes. (Many of the raw vegan pseudoscience promoters have no credentials or training whatsoever in science - keep that in mind when you read their claims.) Tom Billings
