Bowel cancer risk tied to what you eat, not how processed it is
Researchers studied 460,000 Americans over 20 years. Processed meats were linked to higher bowel cancer risk. But certain nutrients protected against it.
Researchers tracked more than 460,000 US adults for over 20 years and recorded more than 10,000 bowel cancer cases. Replacing 10% of ultra-processed foods with whole foods was linked to a 2% lower cancer rate.
Ultra-processed food intake alone showed no clear link with bowel cancer risk. The specific food type mattered.
Ultra-processed meats were linked to higher risk. Whole grains, fiber, dairy, and calcium lowered it.
These protective nutrients worked whether from processed or unprocessed sources. The ultra-processed label alone hid important differences in cancer risk.
Current dietary advice fits these findings: eat more vegetables and whole grains, eat less red and processed meat.

Why it mattersIt shows reducing cancer risk doesn't require eliminating all processed foods. You just need to choose better options within that category.
AustraliaAustralians can cut bowel cancer risk by eating more vegetables, whole grains and dairy, and eating less processed meat, no need to avoid all processed foods.
