About this person

Michael Herschel Greger was born October 25, 1972. He trained as a doctor, then turned his attention to public health and the question of what belongs on a plate. He founded NutritionFacts.org, a site that translates nutrition research into short videos, all arguing for whole plants and against animal products. The project found an audience. His books - How Not to Die, How Not to Diet, and How Not to Age - each hit the New York Times bestseller list. He speaks widely on diet, and the case he makes hasn't changed: that what you eat determines how long you live.
