how much fiber we need to stay healthy
The average adult only eats 15 grams of fiber per day. Women need 25 grams of fiber per day, and men need 38 grams per day, according to the Institute of Medicine.Eating more plant foods -- vegetables, beans, fruit, whole grains, and nuts -- is the best way and is one of the major recommendations from the U.S. government's 2010 Dietary Guidelines.he Dietary Guidelines recommend at least half your grains be whole grains, but with all of the whole grain options available now, it's easy to do even better than that. Whole foods are the preferred way to get fiber, because they also give you nutrients your body needs. 1  1. 2  2. 3  3.
