Core tip: Previously published epidemiologic studies have presented inconclusive results on the association between dairy product consumption and gastric cancer risk. Therefore, we performed a meta-analysis to further explore the possibility of an association. To the best of our knowledge, this is the first meta-analysis that explores the association between dairy product consumption and gastric cancer risk. We analyzed the effects of consuming individual dairy product and the total effects of all dairy product on gastric cancer risk, and we conducted subgroup analyses for the study design, sex, region, and adjustment factors. Our study offers new insight into gastric cancer prevention.
