The Claim

Low-fiber dietary patterns, defined as daily intake below 25 grams, are associated with an estimated 13,145 global colorectal cancer deaths and 305,676 disability-adjusted life years in 2021, with the highest burden observed in populations over 50 years old and in low- and middle-income regions, indicating that insufficient fiber intake contributes significantly to global colorectal cancer mortality and morbidity.

In plain English

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.

    This study found that people who eat too little fiber are much more likely to get colorectal cancer and die from it, especially older adults and people in poorer countries. It confirms that not eating enough fiber is a big reason for these cancers worldwide.
