In this eye-opening replay episode, Dr. Ben Edwards sits down with Dr. Malcolm Kendrick, author of The Clot Thickens: The Enduring Mystery of Heart Disease, to unravel one of the biggest misconceptions in modern medicine — that cholesterol causes heart disease. Dr. Kendrick takes listeners on a journey through decades of research, exposing how flawed studies and powerful industries shaped misguided dietary guidelines. He explains why the real culprit behind heart disease isn’t cholesterol or saturated fat, but damage to the blood vessel lining — the endothelium — and the cascade of clotting that follows. Learn about the vital role of the glycocalyx (the “slick inner lining” of your blood vessels), why statins don’t meaningfully improve mortality, and how lifestyle factors like sun exposure, sugar, stress, and smoking truly impact heart health.
