The Importance of Nutrition

Sally Kohn: I think nutrition is a very asymmetric tool in the sense that most people are either spending way too much time thinking about it or not enough. She says there really is a Goldilocks place for nutrition, where like it should occupy some of your attention. But if you're in pretty good health, she adds, "I don't think nutrition is going to do that much more for you" The author's next book will be published by Simon & Schuster on October 25th at 9 p.m. ET.
