Interpreting your dietary fiber intake status1

< 20 points

20 – 39 points

≥ 40 points

Dietary fiber intake should be increased to help control appetite and reduce the risk of health problems.

Further increasing dietary fiber intake can help improve eating satisfaction and reduce calorie intake.

Dietary fiber intake is adequate, helping to control appetite and stay healthy.

 

 

Daily recommended dietary fiber intake2

  • Children: (Age in years + 5) grams
  • Adolescents and adults: ≥ 25 grams
     

New studies on health benefits of dietary fiber in different population groups:

Children

Women

Elderly

van Gijssel et al. showed a higher dietary fiber intake in children at 1 year of age was associated with a lower cardiometabolic risk factor score at age 6 years, including lower triglycerides and higher high‐density lipoprotein cholesterol3.

Romieu et al. showed women with higher (> 24.2 g/day) intake of dietary fiber have lower risks of breast cancer per 10 g/day of alcohol intake than those with lower (< 18.5 g/day) dietary fiber intake (hazard ratio 1.02 vs. 1.06), with a stronger modulating effect for dietary fiber from vegetables4.

Buil‐Cosiales et al. showed elderly with a higher total intake (≥ 9 servings/day or ≥ 720 g/day) of fruits and vegetables had a significantly lower risk of cardiovascular disease (hazard ratio 0.60) than those with a lower (< 5 servings/day or < 400 g/day) intake of fruits and vegetables5.
