The recommended daily fiber intake varies by age and sex:
- Women under 50: 25 to 28 grams per day
- Men under 50: 31 to 34 grams per day
- Women 51 and older: 22 grams per day
- Men 51 and older: 28 grams per day
These guidelines are from health authorities such as the FDA and USDA. Children have different fiber needs based on age and sex. Most adults consume less fiber than recommended, with an average of around 16 grams per day in the US, which is below these targets. Getting the right amount of fiber supports digestive health and provides other benefits like weight management and gut bacteria balance.
