Quercetin, a dietary supplement that possesses strong antioxidant properties, was previously found to inhibit cancer cell proliferation and blood vessels generation.
In a study published in the Annals of Oncology, high intake of quercetin was reported to be associated with a reduced risk of gastric cancer.
The study evaluated the intake of quercetin and the risk of gastric cancer in 1,616 Swedish. Individuals who had high intake (>11.9 mg) of daily quercetin were 43% less likely to develop gastric cancer than those with low daily intake (<4 mg). Furthermore, the reduction in risk appeared to be much stronger among female smokers (80% reduction).
This study suggests intake of dietary quercetin might reduce the risk of gastric cancer and the protection appears to be particularly strong among female smokers.
