Fiber for long, healthy life
In this study, doctors measured the diets of 1,609 adults who were free from cancer, coronary artery disease, and stroke at the start of this 10-year follow-up trial. Doctors considered total carbohydrates and sugar in the diet, total fiber, and glycemic index and load. Compared to those with the least fiber in the diet, those who had the highest intake of fiber, or highest total fiber in the diet, were almost 80 percent more likely to live a long, healthy life during the 10-year follow-up period.

High-fiber participants were less likely to develop hypertension, diabetes, dementia, depression, or functional disability. “Out of all the variables that we looked at, fiber intake—which is a type of carbohydrate that the body can’t digest—had the strongest influence,” doctors concluded.
