Episode notes
Healthspan vs. Lifespan
- Longevity is a function of lifespan and healthspan, both crucial for a fulfilling life.
- Prioritizing healthspan, or quality of life, often indirectly benefits lifespan.
Centenarian Superpower
- Centenarians, despite sometimes unhealthy habits, possess a genetic advantage that delays disease onset, not resilience to disease.
- Their superpower is delaying diseases like heart disease and cancer, not fighting them better once they appear.
Nutritional Truths
- Definitive nutritional truths are limited: overeating is chronically bad, undereating acutely bad, and certain nutrients are essential.
- Beyond these basics, the human body's complexity makes definitive dietary advice challenging.
