Rich Roll's interview with Zach Bush: Zach Bush, MD is a triple board certified physician specialising in Internal Medicine, Endocrinology and Metabolism, as well as in Hospice and Palliative care. The director of M Clinic in Virginia, Dr. Bush has published peer-reviewed articles and book chapters in the areas of infectious disease, endocrinology, and cancer. This is a mind-blowing conversation that explores new insights into the mechanisms behind human health and longevity. It's about the massive and misunderstood impact of industrial farming, chemical pesticides, the pharmaceutical industry and even errant Western medical practices have on both human and planetary health.
