Daily Fiber Intake Calculator: Are You Getting Enough?

Quickly determine your recommended daily dietary fiber intake based on your age and gender to support optimal digestive health, weight management, and overall wellness.

The Importance of Dietary Fiber

Dietary fiber is an essential plant-based nutrient that your body cannot digest. Unlike other carbohydrates that break down into sugar, fiber travels through your digestive system largely intact. It plays a vital role in maintaining good health by promoting regular bowel movements, feeding beneficial gut bacteria, and helping to control blood sugar levels and appetite.

Recommended Daily Fiber Intake (IOM)

The Institute of Medicine (IOM) provides the following evidence-based recommendations for daily fiber intake for adults:

Age Group Recommended Fiber (grams/day)
Men (19–50 years)38 grams
Women (19–50 years)25 grams
Men (51+ years)30 grams
Women (51+ years)21 grams
