Adopting a pro-inflammatory diet, as measured by the Dietary Inflammatory Index (DII), significantly increases the risk of developing colorectal cancer (CRC) and cancer-related mortality.
To lower your risk of colorectal cancer, aim for an anti-inflammatory diet. This means minimizing processed foods, added sugars, and refined grains, while maximizing fruits, vegetables, whole grains, and healthy fats. You don't need to calculate a score; just focus on whole, unprocessed foods.
GoodSupportsHIGH confidence
individuals in the highest versus the lowest (reference) DII category had an overall 40% increase in CRC risk of [relative risk (RR) = 1.40, 95% confidence interval (CI): 1.26, 1.55, p < 0.001].
Why this rating
Based on multiple prospective studies and meta-analyses with consistent positive associations, though observational.
