The overarching theory Dr. Deans explores is that our bodies and brains do best in conditions for which they are evolved. She digs up scientific information and presents it in that context. She feels that by studying evolutionary medicine, we come closer to the answers for optimal conditions for health and vitality. The dietary basics of evolutionary medicine are simple: don't eat very much fructose, omega-6 rich industrial vegetable oils, grains (such as wheat, rye, barley, spelt, quinoa, oats, corn, etc.), or processed "fake" food in general. Eat as much local, farmstand, grassfed, pastured, wild-caught as you care for. That's vegetables, meat, fish, nuts, eggs, and fruits. In her opinion, if you have no serious medical conditions, it's perfectly healthy to have high-fat dairy, safe starches such as white rice or potatoes, red wine, and dark chocolate in moderation. Also, get plenty of sleep and play.
