  • High-fiber foods common in blue zones include breads, beans, greens, and nuts.

If you want to live a long, healthy life, there is good evidence that it is important to get enough fiber.

Foods rich in fiber, including lots of carbohydrates, are prominent in diets in the blue zones, areas of the world where people live the longest, healthiest lives, according to research.
