The Claim
Higher dietary selenium intake is associated with reduced colorectal cancer risk among individuals carrying the IL10 rs1800871 G allele (GA/GG genotypes), with an adjusted odds ratio of 0.61 (95% CI: 0.42–0.87), but not among individuals with the AA genotype.
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.
People with a specific genetic variant (IL10 rs1800871 G allele) who consume more selenium through their diet have a lower risk of colorectal cancer compared to those with the AA genotype, based on observed statistical associations.
See the scientific wording
The association between higher dietary selenium intake and reduced colorectal cancer risk is modified by the IL10 rs1800871 polymorphism, with a significant interaction (P = 0.043), such that the protective effect is observed only in carriers of the G allele (GA/GG genotypes), with an adjusted odds ratio of 0.61 (95% CI: 0.42–0.87), but not in homozygous AA carriers.
When a person eats more selenium, their body uses it to make proteins that reduce harmful inflammation in the gut. In people with a specific gene version, this triggers more of a calming signal called IL-10, which stops the gut lining from becoming damaged and turning into cancer. People without this gene version don’t get this extra protection, even if they eat more selenium.
What the research says
1 studyThis study found that eating more selenium may lower the risk of colon cancer—but only for people who have a specific version of their IL10 gene. People with a different version didn’t get any benefit.
