Pioneering research shows that chronic diseases can be halted, even reversed, with simple –  but comprehensive –  lifestyle changes. In this presentation, behavioural medicine scientist Larry Scherwitz, PhD, reviews the lifestyle medicine-based, randomized controlled clinical trials that have benefited patients diagnosed with coronary heart disease, prostate cancer and Alzheimer’s disease. The evidence includes, but goes beyond, the purely physical side of health to include the psychological, emotional and spiritual aspects so vital to healing.
