Ultra-Processed Foods: Some Raise Colon Cancer Risk
16 Oct
Summary
- Whole grain and dairy from processed sources linked to lower risk.
- Processed meat from ultra-processed sources linked to higher risk.
- Replacing some processed foods with minimally processed options helps.
A recent study published in PLOS Medicine reveals that the type of ultra-processed food consumed impacts colorectal cancer risk. Researchers found no link between overall ultra-processed food intake and the disease. However, consuming whole grain and dairy products classified as ultra-processed was associated with a decreased risk of colorectal cancer.
In contrast, the study observed a higher risk of colorectal cancer with increased consumption of processed meats originating from ultra-processed food sources. The findings support existing dietary recommendations to prioritize whole grains, fiber, and dairy while limiting processed meats for cancer prevention.
The research analyzed data from over 460,000 adults aged 50 to 71 over approximately 18 years. This observational study primarily included older, white Americans, and intake was measured only once. Therefore, results may not generalize to younger or more diverse populations. Replacing some ultra-processed food consumption with minimally processed alternatives was also identified as a strategy to reduce cancer risk.
