Nutrition can be a touchy topic, like politics or religion, that people take very personally, but good nutrition is the foundation not only for general health but also for high-performance fitness. Much of the public information about diet, particularly the emphasis on low fat and high carbs, has resulted in a near epidemic of obesity and type II diabetes. In this first of a two-part lecture excerpt, Coach Glassman explores some of the science behind nutrition and the body, particularly the role of insulin in health and disease. "Syndrome X," the "deadly quartet" (obesity, glucose intolerance, high blood pressure, high triglycerides), and coronary heart disease, he claims, are avoidable through dietary means.
Part 2 will address the refined dietary needs of the athlete and what's required to optimize performance.
