The Claim

Between 1990 and 2021, the absolute number of deaths attributable to low-fiber diets in colorectal cancer increased by 35.7%, from 9,689 to 13,145, despite a 42.5% decline in age-standardized mortality rates, with population growth and aging identified as the primary drivers of this increase in total deaths.

Description
1 study reviewed
In plain English

Although the rate of colorectal cancer deaths per person has decreased since 1990, the total number of deaths from this cancer linked to low-fiber diets has risen because the global population has grown and aged.

See the scientific wording

The global burden of colorectal cancer attributable to low-fiber diets increased by 35.7% in absolute deaths (from 9,689 to 13,145) between 1990 and 2021, despite a 42.5% decline in age-standardized mortality rates, reflecting population growth and aging as key drivers of rising total cases.

    Even though fewer people are dying from colon cancer per capita, more people are living longer and eating less fiber, so the total number of deaths from this cause has gone up. The study confirms this trend.
