The recommended daily fiber intake varies by age, sex, and dietary guidelines but generally falls within these ranges:
- 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
Most health authorities, including the USDA and European Food Safety Authority, suggest around 25 to 30 grams of fiber daily for adults to support digestion, cardiovascular health, and prevention of chronic diseases. However, the average intake is often lower than recommended, around 16 to 20 grams per day in many populations, which suggests increasing fiber intake is beneficial for most adults.
