Looking to add more fiber to your diet? Fiber — along with adequate fluid intake — moves quickly and relatively easily through your digestive tract and helps it function properly. A high-fiber diet may also help reduce the risk of obesity, heart disease and diabetes.

Women should try to eat at least 21 to 25 grams of fiber a day, while men should aim for 30 to 38 grams a day.
