Dietary fiber intake reduces risk for gastric cancer: a meta-analysis.

Abstract in brief

• This meta-analysis of 21 studies found that higher dietary fiber intake is associated with a lower risk of gastric cancer, with a 10g/day increase in fiber linked to a 44% reduction in risk.
• The analysis showed consistent results regardless of study design, location, or fiber type, and suggested the protective effect is independent of other risk factors.
• Despite these findings, there was significant heterogeneity among the studies, so further research is needed to confirm the strength and exact nature of this relationship.]
