Our guest is Dr. Neal D. Barnard, a faculty member of the George Washington University School of Medicine who is also a bestselling author and president of the Physicians Committee for Responsible Medicine. He joins us to discuss his new book, "Your Body in Balance." As was noted of this book by Dr. Robert Ostfeld, Director of Preventive Cardiology at Montefiore Health System in New York: "[This book] is an incredible resource. If you have ever wondered how the food you eat impacts your fertility, erectile function, thyroid function, skin, hair, and so much more, wonder no longer. This book shows us how the food we eat can literally change our hormones, our mood, and our health."
