The Claim
High dietary nitrite intake is associated with a 31% increased risk of gastric cancer (summary relative risk: 1.31, 95% CI: 1.13–1.52), based on a meta-analysis of 19 studies including 663,634 participants, with consistency across case-control studies and geographic regions and minimal heterogeneity.
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 a lot of foods with nitrites might raise your chances of getting stomach cancer by about one-third, according to a big review of many studies.
See the scientific wording
High dietary nitrite intake is associated with a 31% increased risk of gastric cancer when comparing the highest versus lowest intake categories (summary relative risk: 1.31, 95% CI: 1.13–1.52), based on a meta-analysis of 19 studies including 663,634 participants. This risk elevation was consistent across case-control studies and geographic regions, with minimal heterogeneity.
What the research says
1 studyStudy: Dietary Nitrates, Nitrites, and Nitrosamines Intake and the Risk of Gastric Cancer: A Meta-Analysis
The study looked at the same thing as the claim—dietary nitrite intake and its link to stomach cancer—and found exactly the same 31% increased risk, so it supports the claim.
