So just how much fiber do you need? The national fiber recommendations are 30 to 38 grams a day for men and 25 grams a day for women between 18 and 50 years old, and 21 grams a day if a woman is 51 and older. Another general guideline is to get 14 grams of fiber for every 1,000 calories in your diet.
The recommended daily intake of fiber is 20 to 35 grams per day for adults, adolescents, and older children. Desirable fiber intake for children (under 18) is calculated by age plus five grams. For example, a six-year-old needs 11 grams of fiber per day. The average American only gets 10 to 15 grams of fiber per day so most people need to increase their fiber intake.
