The Claim

A dose-response analysis of data from 5 studies indicates that each 0.1 mg/day increase in nitrite intake is associated with a 7% increase in gastric cancer risk (summary relative risk: 1.07, 95% CI: 1.00–1.15), suggesting a linear relationship where even small increments in nitrite consumption may elevate cancer risk.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

Quantitative

In plain English

Eating more nitrites, even just a tiny bit extra each day, might raise your chance of getting stomach cancer, according to research that looked at several studies.

A dose-response analysis indicates that each 0.1 mg/day increase in nitrite intake is associated with a 7% increase in gastric cancer risk (summary relative risk: 1.07, 95% CI: 1.00–1.15), based on data from 5 studies. This linear relationship suggests that even small increments in nitrite consumption may elevate cancer risk.

What the research says

1 study
  1. Study: Dietary Nitrates, Nitrites, and Nitrosamines Intake and the Risk of Gastric Cancer: A Meta-Analysis

    The study looked at nitrite intake and found it increases stomach cancer risk, just like the claim says, so it supports the idea that more nitrite raises risk.
