People from the Ryukyu Islands in Japan (of which Okinawa is the largest) have the highest longevity in the world. This is partly attributed to the Ryukyuan diet, but also to other factors such as lifestyle, genetics, and psycho-spiritual health.
The diet followed is low calorie, and low in complex carbohydrates. It also incorporates fish. Moderation in eating is the approach taken by most Ryukyuans.
A study of the high rate of centenarians in Okinawa was carried out to derive any useful lessons for the rest of the world.
