The Claim
In White British adults, specific combinations of reference alleles in the EPDR1 gene interact with fish consumption exceeding twice weekly to reduce colorectal cancer risk by 15%.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
White British adults with certain genetic variants in the EPDR1 gene who eat fish more than twice a week have a 15% lower risk of colorectal cancer compared to those with the same variants who eat less fish.
See the scientific wording
In White British adults, genetic variants in the EPDR1 gene interact with fish consumption to modify colorectal cancer risk, with individuals carrying a specific combination of reference alleles showing a 15% reduced risk when consuming fish more than twice weekly, suggesting a genetic modulation of dietary effects on cancer development.
When people eat fish often, fatty acids from the fish enter the colon and reduce the activity of a protein called EPDR1 that makes cells multiply and spread. People with certain versions of the EPDR1 gene have more of this protein, but the fatty acids from fish turn it down, so cells don't grow out of control and tumors don't form as easily.
What the research says
1 studyStudy: Genome-Wide Interaction Study of Dietary Intake and Colorectal Cancer Risk in the UK Biobank
People with a certain version of the EPDR1 gene who eat fish more than twice a week have a 15% lower chance of getting colorectal cancer, and this study found exactly that in a large group of British adults.
