High intake of ultra-processed foods linked to 45% higher risk of precancerous colon polyps in women under 50.
A new study links high consumption of ultra-processed foods—such as sugary drinks, packaged snacks, processed meats, and ready meals—to a 45% increased risk of precancerous colorectal adenomas in women under 50.
Analyzing data from over 29,000 female nurses followed for decades, researchers found those eating the most ultra-processed foods were significantly more likely to develop these polyps, even after accounting for other risk factors.
While the study does not prove causation, it adds to growing evidence that such foods, which are often high in sugar, unhealthy fats, sodium, and additives, may contribute to rising rates of early-onset colorectal cancer.
Experts stress the need for further research and public health efforts to improve access to whole, minimally processed foods.
