September 24, 1955. President Eisenhower is asleep in his bed at his in-laws’ house in Denver. At around 2 AM in the morning, he’s jolted awake by chest pains. No one realizes it until the morning, but Eisenhower has had a heart attack. His cardiologist calms the public and tells them that their President will be alright – with some lifestyle changes partially inspired by new, cutting-edge research from a little-known scientist: Ancel Keys. And that very research will change the way Americans, and the world, will eat forever. How did Keys, an oceanographer-turned-nutrition-scientist, end up changing the world’s relationship with fats? And was this a change for the better? Thank you to our guests, Dr. Steven Nissen, Chief Academic Officer, Sydell and Arnold Miller Family Heart, Vascular & Thoracic Institute at the Cleveland Clinic; Sarah Tracy, Edith Kinney Gaylord Presidential Professor, History of Medicine and Food Studies at the University of Oklahoma; and Nina Teicholz, investigative science journalist and author of The Big Fat Surprise: Why Butter, Meat and Cheese Belong in a Healthy Diet. **This episode originally aired September 21, 2020.
