how much fiber per day
Fiber is a type of carbohydrate that the body canât digest. Though most carbohydrates are broken down into sugar molecules, fiber cannot be broken down into sugar molecules, and instead it passes through the body undigested. Fiber helps regulate the bodyâs use of sugars, helping to keep hunger and blood sugar in check. Children and adults need at least 20 to 30 grams of fiber per day for good health, but most Americans get only about 15 grams a day. Great sources are whole fruits and vegetables, whole grains, and beans. Soluble fiber, which dissolves in water, can help lower glucose levels as well as help lower blood cholesterol.
