Surprising Findings
The link between UPFs and polyps remained strong even after excluding processed meats and adjusting for BMI and key nutrients.
Most assume the harm comes from salt, sugar, or saturated fat — but this study shows the processing itself (additives, emulsifiers, ultra-refinement) may be independently toxic to the colon.
Practical Takeaways
Swap just 2 UPF servings per day for whole foods — like replacing sugary cereal with oatmeal or packaged snacks with nuts and fruit — to significantly lower your polyp risk.

People who eat a lot of ultra-processed foods have a 17% higher chance of developing high-risk colorectal polyps, even when processed meats are not counted, indicating that other ingredients in these foods may play a role in this risk.
People who eat more ultra-processed foods have a higher likelihood of developing two types of precancerous growths in the colon, even when accounting for other dietary factors and body weight.
Eating certain types of ultra-processed foods, such as packaged snacks, ready-to-eat meats, and fatty condiments, is linked to a higher chance of developing high-risk polyps in the colon, which can be precursors to colorectal cancer.
Eating ultra-processed foods may increase the risk of developing colorectal polyps even after accounting for factors like poor diet, obesity, and low fiber intake, indicating that the processing of the food itself could play a direct role in this process.
People who eat 10 servings of ultra-processed foods per day have a 45% higher rate of developing colorectal adenomas than those who eat three servings per day.
