Baxter Montgomery, M.D., is a busy cardiologist in Houston. As a Clinical Assistant Professor of Medicine in the Division of Cardiology at the University of Texas and a Fellow of the American College of Cardiology, he manages arrhythmias and coronary disease, performs angiography, defibrillator implants, and other hospital procedures, and teaches young physicians. But in 2002, he had to take stock of his own health. His cholesterol was far into the not-so-healthy zone. Around the same time, his mother, who had had heart disease and diabetes, succumbed to complications of her illness and of the medications used to treat it. This wake-up call made him re-evaluate not only his own health, but also his approach to medicine. Digging into the scientific literature and nutrition books, he came to some stark conclusions. A healthy diet was plant-based, and animal-based foods had to go.
