The daily fibre intake for adults on a 2000-calorie diet is 25 grams per day. This number may also depend on age or gender. Women under 50 should have 21 to 25 grams per day and men under 50 should include 30 to 38 grams per day. Children between ages 1 and 18 should eat 14 to 31 grams daily. There is evidence that even higher fibre intakes may significantly reduce the risk of chronic health concerns.
