Catherine Shanahan, MD is science director of the LA Lakers PRO Nutrition program, consultant for Mark Sisson's Primal BluePrint certification program, board certified Family Physician and author of the underground classic Deep Nutrition: Why Your Genes Need Traditional Food, and the easy-to-read executive summary of holistic nutrition, Food Rules: A Doctors Guide to Healthy Eating. She is also a Cornell trained genetic researcher with over two decades of clinical experience. Dr Shanahan became an advocate for healthy living when she began to observe dramatic changes in the bone structure, immune-system hyper-reactivity, and behavioral development across generations of patients in the same family.
Deep Nutrition describes how these changes in genetic health have resulted from changes to our eating habits. She ditches the Food Pyramid and outlines the original human diet based around common elements to all traditional diets, the 4 Pillars of World Cuisine. These are the four categories of foods that helped to make our ancestors strong and fit, but most of us today are lucky if we include one of the four. Food Rules provides a quick, how-to guide to expanding our diets, including new foods and adapting new habits to create a powerfully healthy lifestyle.
Dr Cate wants to empower her patients and her readers with the knowledge to lose weight, get healthy, and have healthy children by following principles of traditional nutrition. She has received many thank you letters from around the world written by readers who have astounded their friends, family, and their doctors and been taken off chronic prescriptions.
