How Much Fiber Per Day: Grams by Age and 18 High Fiber Foods
Most adults need 22 to 34 grams of fiber a day, based on 14 grams for every 1,000 calories. That is 28 grams on a 2,000-calorie diet, the same as the label Daily Value. Women aged 19 to 30 need about 28 grams and men the same age about 34. Beans, lentils, peas, berries, pears and whole grains close the gap fastest.
