124,590-Person PURE Study Ties Ultraprocessed Grains To Bowel Disease Risk
The McMaster-led PURE study spanned 21 countries; eating five or more daily servings of any ultraprocessed food nearly quadrupled the risk.
- High ultraprocessed-grain intake, 19+ grams daily, carried hazard ratio 1.86 versus under 9 grams.
- Five or more ultraprocessed-food servings daily raised risk to HR 3.95 versus under one serving.
- Fresh bread and rice intake tracked with lower inflammatory bowel disease risk in the same cohort.
Why it matters: Diet composition, not portion size, now carries a measured hazard ratio for a chronic bowel disease.
