Eating foods with fiber can help lower your chances of getting long-term illnesses like diabetes or heart disease by improving things like blood sugar, cholesterol, and gut health.

Eating more fiber might help people live longer by lowering their chances of dying from cancer.

The way people report how much fiber they eat affects whether studies find a link between fiber and colorectal cancer. When people use food diaries, a protective link is seen; when they use questionnaires, no significant link is found.

Eating more fiber and whole grains like oats, brown rice, and beans seems to help your body handle sugar better, keep your weight in check, and lower your risk of heart disease.

Eating more fiber in your diet might help lower your chances of getting cancer overall, according to a big review of past studies.

Diets low in fiber, defined as less than 25 grams per day, are linked to approximately 13,145 deaths and 305,676 years of lost healthy life from colorectal cancer globally in 2021, with the greatest impact seen in people over 50 and in low- and middle-income countries.
