Foods rich in fiber, including plenty of carbohydrates, are featured prominently in diets in the Blue Zones, areas of the world where people live the longest, healthiest lives, according to research.
Blue Zones represent a wide variety of cuisines, like Japanese, Greek, Italian, and Costa Rican. While the specific foods vary, common high-fiber foods groups like beans, nuts, whole grains, herbs, and green veggies make up the backbone of Blue Zones diets.
Research suggests getting enough fiber is important for digestive health, stable blood sugar, and prevention of chronic illnesses like heart disease and cancer. Foods rich in fiber can also help with weight loss by keeping you full after eating.
