December 29, 2009 — Greater adherence to a relative Mediterranean diet is associated with a significantly lower risk for incident gastric adenocarcinoma, according to the results of a prospective cohort study reported online in the December 9 issue of the American Journal of Clinical Nutrition.
"The Mediterranean dietary pattern is believed to protect against cancer, although evidence from cohort studies that have examined particular cancer sites is limited," write Genevieve Buckland, BS, from the Catalan Institute of Oncology, Idibell, in Barcelona, Spain, and colleagues from the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort study.
The Mediterranean diet includes a proportionately high intake of fruit, nuts, fiber, seeds, vegetables, olive oil, and a moderate intake of wine. These foods are rich in antioxidants that may help prevent cancer, such as vitamin C, carotenoids, phenols, and flavonoids. In addition, consumption of red and processed meat is relatively low.
Several studies have shown a protective effect of the Mediterranean diet on health and its association with a reduced risk for cancer and other chronic diseases. However, only breast cancer and colorectal cancer risks have been examined separately, and no studies to date have evaluated the association between adherence to a Mediterranean diet and the risk for gastric adenocarcinoma.
