Dietary fiber intake and risk of type 2 diabetes in a general Japanese population: The Hisayama Study

Imbibing the habit of eating high-fiber foods routinely may improve our chances of staying free from type 2 diabetes.

This study examined the association between the frequency of consumption of fiber-rich foods and the likelihood of acquiring type 2 diabetes. Researchers surveyed the diet and health of 1,892 Japanese men and women within the age bracket of 40-70 years for a duration of 14 years. During the course of the study, 280 participants were diagnosed with type 2 diabetes. 

Researchers noticed that the more fiber-containing foods participants consumed, the better protected they are from type 2 diabetes. This study concluded that "the intake of high dietary fiber foods might be useful for diabetes prevention."
