Daily Fiber Requirements 

The Institute of Medicine recommends that children and adults consume 14 grams of fiber for every 1,000 calories of food they eat each day.

That means a person who eats 2,500 calories each day should get at least 35 grams of fiber daily, while a person who eats 1,700 calories each day needs somewhat less fiber—about 24 grams. A toddler who eats only 1,300 calories each day needs about 18 grams of fiber.

Here are general fiber intake recommendations for different age groups and genders. These recommendations are based on the average daily calorie intake for people in these age and gender groups. Individuals who consume more or fewer calories than this average should adjust their fiber intake accordingly.
