The Okinawa Diet is a traditional dietary pattern characterized by high consumption of vegetables, legumes, and whole grains, with moderate fish intake and minimal processed foods, meat, and dairy. This nutrient-dense, calorie-restricted approach is associated with lower rates of chronic disease and exceptional longevity in the Okinawan population, primarily through mechanisms involving reduced oxidative stress, improved metabolic flexibility, and modulation of nutrient-sensing pathways like mTOR and AMPK.
