The 5 best food swaps to lower cholesterol, protect your heart and to live longer | Dr. Alice Lichtenstein

Dr. Alice Lichtenstein joins ZOE Science & Nutrition to debunk common myths about dietary fat. She explains why the type of fat matters more than the amount, how saturated fat drives heart disease, and why replacing butter with olive oil could help you live longer. The conversation covers the history of egg fears, the mistake of low-fat high-sugar foods, and practical food swaps for a heart-healthy diet. Lichtenstein also discusses cholesterol numbers, the liver's role in converting sugar to fat, and the limited benefits of grass-fed beef.
