Read Summary →Catherine Shanahan, MD
"Family physician who argues traditional food preparation, not modern industrial diets, is what your genes actually need."
Catherine Shanahan, MD, is a family physician with a background in biochemistry and genetics, and the former team physician for the Los Angeles Lakers. After completing her medical training and a period of research and practice in Japan and China, she opened a family practice in Kauai, Hawaii, where she began treating chronic disease through a lens combining evolutionary biology, genetics, and traditional nutrition. Drawing on Weston A. Price's early-20th-century field surveys of traditional diets around the world, Shanahan developed the \"Four Pillars\" framework at the center of Deep Nutrition, and has continued to expand her critique of industrial food, especially refined vegetable oils, in subsequent books including Dark Calories.
