Darrin Carlson over at Lean, Mean, Virile Machine has a thought-provoking piece entitled The Five Failings of Paleo. It’s about the history of the modern paleo diet movement. Despite the title, it’s pro-paleo, even if it’s not your version of paleo.
PS: When I write “paleo,” you can subsitute Paleolithic, caveman, Stone Age, or Old Stone Age.
