Born to Live Longer? Inside the Genetics and Biology of Centenarians

This podcast explores the genetic and lifestyle factors contributing to exceptional longevity, featuring Dr. Paola Sebastiani, a biostatistics professor and senior investigator with the New England Centenarian Study. The discussion challenges the idea of a single "longevity gene," highlighting the heterogeneity in how people reach extreme old age and the potential for multiple genetic pathways. Dr. Sebastiani notes the importance of APOE and other genetic variants and discusses the limitations of using polygenic risk scores to predict longevity. The conversation emphasizes the significance of nutrition, particularly maintaining a balanced diet and consistent protein intake, and touches on the role of inflammation, gut microbiome, and the potential benefits of flavonoids and dark chocolate. Dr. Sebastiani underscores that centenarians offer a positive perspective on aging, demonstrating the possibility of healthy and mentally positive later years.
