The Claim
High dietary nitrate intake is associated with a 20% reduced risk of gastric cancer, as evidenced by a summary relative risk of 0.80 (95% CI: 0.69–0.93) from a meta-analysis of 19 studies involving 650,826 participants, with the protective effect primarily observed in case-control studies and European populations despite heterogeneity across studies.
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.
Eating more nitrate-rich foods might lower your chances of getting stomach cancer by about 20%, based on a big review of many studies, especially in European countries.
See the scientific wording
High dietary nitrate intake is associated with a 20% reduced risk of gastric cancer when comparing the highest versus lowest intake categories (summary relative risk: 0.80, 95% CI: 0.69–0.93), based on a meta-analysis of 19 studies including 650,826 participants. This protective effect was primarily observed in case-control studies and European populations, though heterogeneity exists across studies.
What the research says
1 studyStudy: Dietary Nitrates, Nitrites, and Nitrosamines Intake and the Risk of Gastric Cancer: A Meta-Analysis
This study looked at the same thing as the claim—dietary nitrate intake and stomach cancer—and found the same 20% lower risk, so it supports the claim.
