Fiber is the only carbohydrate that cannot be digested by your body. While other carbohydrates are converted into sugar, fiber comes out of the body without digestion. It regulates the utilization of sugars and keeps blood sugar in normal levels. It also suppresses hunger through early satiety.
It is recommended to have a minimum 20 to 30 grams of fiber every day. Whole fruits, whole grains, vegetables and beans are rich in fibers.
