A recent U.S. News and World Report ranking of 29 diets that are popular in the U.S. today placed The Paleo Diet at No. 28.
A renewed interest in the diet of cavemen resulted when gastroenterologist Walter Voegtlin wrote the Stone Age Diet in 1975. He based his book on his work with patients suffering colitis, Crohn’s disease, irritable bowel syndrome and indigestion.
In the early 2000s, Loren Cordain, a professor in the Department of Health and Exercise Science at Colorado State University, also was studying the human diet during the Stone Age. He discovered that the chronic diseases, which he says afflict 50 to 65 percent of the Westernized adult population, were rare or nonexistent in hunter-gatherer societies.
And he hypothesized that “when hunter/gatherer societies transitioned to an agricultural grain-based diet, their general health deteriorated.”
In 2001, he authored The Paleo Diet (John Wiley & Sons) that claims we can turn back the clock on disease and become more healthy by eating and exercising as they did 2 ½ million to 10,000 years ago; the time before crops and animals were domesticated.
