Associations between dietary polyphenols and risks of gastric precancerous lesions and cancer

BACKGROUND While numerous studies have examined the associations between dietary polyphenol subclasses (i.e. , flavonoids, phenolic acids, lignans, and stilbenes) and the risk of gastric cancer (GC), evidence regarding their relationships with gastric precancerous lesions (GPL) and their subtypes [i.e. , chronic atrophic gastritis, intestinal metaplasia (IM), and low-grade dysplasia (LGD)] remains extremely limited. AIM To investigate the associations between dietary polyphenol subclasses and bo
