Sugar-sweetened drinks linked to increased risk of colorectal cancer
Colorectal cancer diagnoses have increased among people under age 50 in recent years ... heavy consumption of sugary drinks can increase the disease risk.
“In past work, we have shown that poor diet quality was associated with increased risk of early-onset colorectal cancer precursors ... Despite the small number of cases (in this study), sugar intake is playing a role in increasing adulthood colorectal cancer risk before age 50 ... Metabolic problems, such as insulin resistance, may play an important role in the development of this cancer in younger adults.”
Compared with women who drank less than one 8-ounce serving per week of sugar-sweetened beverages, those who drank two or more servings per day had just over twice the risk of developing early-onset colorectal cancer (diagnosed <50yo).
- 16% increase in risk for each 8-ounce serving per day, in adulthood.
- 32% increase in risk for each 8-ounce serving per day, in adolescence.
