Heart disease is the number-one killer of adults in America. But as Cadwell B. Esselstyn Jr., MD, of the Cleveland Clinic, the country’s number-one heart hospital, tells us, “Coronary heart disease need never exist, and if it does exist, need not progress.” The cure comes not from costly surgeries, states Dr. Esselstyn, but by diet alone. In a 20-year study of patients with advanced coronary artery disease, Dr. Esselstyn has shown that his plant-based, oil-free nutrition plan not only stops heart disease from progressing -- it actually reverses it. His method, published in the book Prevent and Reverse Heart Disease (Avery, 2007), has helped hundreds of patients, including Bill Clinton, change their eating habits and their lives. Here’s how it can help you too.
