Gastric cancer (GC) is considered as most fourth common cancer in the world. Findings from animal, experimental and epidemiologic studies indicate that diet plays an important role in the etiology of stomach cancer. Among dietary factors, Zinc status has received great attention in recent years. The purpose of the present study was to review the association of serum levels of Zinc, dietary intake of Zinc and GC risk. A complete search was performed about the association of Zinc status and risk of GC was in databases electronic through such as ISI web of science, PubMed, Scopus, IrMedx and SID. Our results of current review suggest that dietary intake of Zinc and serum levels of Zinc are lower in GC patient. In other word, high serum levels of Zinc may be protective in GC risk. However, it seems further studies in particular epidemiological studies with large scale setting are required to reach a definite conclusion.
