A surprisingly high number of people here live beyond 100 years, and the secret to their longevity is believed to lie in their unique diet and lifestyle.
Here are some key factors that make the Okinawan diet one of the healthiest in the world.

Okinawans consume a diet rich in fiber, primarily through vegetables and sweet potatoes.
