Gastric cancer risk lowered by eating more fibre
Twenty-one case control and cohort studies were included in the analysis, which found an increase in fibre intake of 10g per day was associated with a statistically significant 44% decreased risk of gastric cancer.
Various mechanisms for the effect have been proposed, the authors said, including that fibre scavenges potentially carcinogenic nitrites. High fibre intake might also indicate a diet rich in a variety of nutrients.
Gastric cancer survival has not improved in two decades in the US.
