On the Moral Imagination Podcast, host Michael Matheson Miller speaks with heart surgeon, Dr. Philip Ovadia MD, about metabolic health, diet, science, cholesterol, insulin resistance, the US government food pyramid, Ancel Keys and the cholesterol - saturated fat -heart disease hypothesis. They discuss medical education, health insurance, scientism, and some of the obstacles doctors and scientists face with “group think.” Dr Ovadia tells his story of how lost 100 pounds changed everything he learned about fat and food. He explains that while half of the patients who have heart attacks or heart surgery have normal levels of cholesterol, over 90% have insulin resistance. He argues that metabolic health is not only important for heart health, but for mental health, and plays a key role in preventing cancer and Alzheimer’s disease.
