Longevity Foods for People Over 50

from Doctor Next Door Hosted by Doctor Next Door

Outlines seven foods recommended for people over 50 to support longevity and mitochondrial health by boosting NAD levels, a key molecule for energy production that declines with age. Drawing on Dr. David Sinclair’s research on sirtuins, the suggested foods include grass-fed red meat (especially organ meats), probiotic-rich foods like sauerkraut, onions for quercetin, wild-caught fatty fish for omega-3s, and nutrient-dense vegetables like parsley, celery, and purple cabbage. The transcript emphasizes obtaining nutrients from whole foods rather than supplements and provides historical context on niacin (Vitamin B3) deficiency and pellagra.
