The Centenarian Secret: Foods Doctors Eat Every Day for Maximum Healthspan

39. Chaga Mushroom (Brewed Tonic): The DNA Protector

Chaga mushroom, often consumed as a brew or tonic, is revered by experts for its off-the-charts antioxidant capacity (high ORAC score), which provides exceptional defense against cellular damage and aging. What it trains: It’s rich in melanin and powerful polyphenols that actively scavenge free radicals and support DNA repair mechanisms. Why it helps: By reducing the accumulation of oxidative stress—a primary driver of age-related disease—Chaga helps maintain cellular integrity over decades. How to use: Steep Chaga chunks or powder in hot water to create a mild, earthy tonic, often combined with warming spices. This simple, warming ritual provides a concentrated, non-caffeinated boost to your body’s deep internal defense systems.

40. Sea Buckthorn: The "Omega-7" Skin and Mucosal Guard

Sea buckthorn, a vibrant orange berry found in coastal and mountainous regions, is a hidden gem in longevity medicine specifically for its rare concentration of Omega-7 (palmitoleic acid). While Omegas 3, 6, and 9 are widely discussed, Omega-7 is critical for maintaining the health of "mucosal liners"—the protective barriers in your eyes, mouth, gut, and urogenital tract that often dry out or thin as we age. By strengthening these internal seals, sea buckthorn acts as a first line of defense against systemic infections and chronic inflammation. It also boasts incredible levels of Vitamin C and Vitamin E, which support skin elasticity and accelerate wound healing.
