The association between ultra-processed food consumption and colorectal cancer risk is significant in men but not in women, and there is no significant association with prostate, rectal, pancreatic, or central nervous system cancers.
If you are male, be particularly mindful of UPF intake as it is linked to a higher risk of colorectal cancer. For women, the link to colorectal cancer was not statistically significant in this study. There was no significant link found for prostate, rectal, pancreatic, or brain cancers.
GoodQualifiesMEDIUM confidence
Subgroup analyses showed that a positive association between UPFs consumption and colorectal cancer was observed among men (OR = 1.31, 95% CI: 1.15–1.50), whereas no significant association was observed among women (OR = 1.10, 95% CI: 0.94–1.29)... not rectal cancer (OR = 1.18, 95% CI: 0.97–1.43) and prostate cancer (OR = 1.03, 95% CI: 0.93–1.12).
Why this rating
Based on subgroup analyses of the same meta-analysis; heterogeneity was moderate to high in some subgroups.
