Stress, autoimmune diseases, obesity. These modern epidemics were not a part of the paleolithic landscape, but they certainly plague us now. Chris Kresser, author of "The Paleo Cure" and functional medicine practitioner, recommends that we look back to the wisdom of our ancestors to experience vibrant health today. In this episode, he tells us his story: how a health crisis precipitated his interest in nutrition and medicine, and how the Weston A. Price Foundation played a part in his journey back to health. Chris emphasizes how geography and genetics play a role in determining our diet and he touches on the pivotal role of fats and the need to decrease or manage our stress.
