Core tip: Gene-diet interactions related to gastric carcinogenesis may provide a unique environment for cancer growth or suppression in each individual. Gene-diet interactions may explain the large variation in gastric cancer incidence in different populations and the inconsistent findings of previous gene or diet studies. Therefore, this review provides an overview of the published epidemiological studies that have investigated the interactions between gene variants and dietary factors associated with gastric cancer risk.
