The study, published in Nutrition and Cancer (2005, vol 52, no 2), investigated the effects of nutrient intake and H. pylori infection on gastric cancer risk. Researchers at the Hanyang University College of Medicine, in Seoul, Korea, compared the nutrient intake of 136 participants with histologic evidence of gastric cancer and 136 healthy participants (controls). Food frequency questionnaires obtained from the participants were analyzed to determine nutrient intake and vitamin supplement use over a 12 month period. The researchers assessed the effects of nutrient intake and H. pylori infection on gastric cancer risk using a multivariate model.
The researchers found that a high intake of antioxidants including vitamins A, C, E, and beta-carotene, lowered the risk of gastric cancer. Furthermore, among the H. pylori infected participants, those with the highest intake of vitamins C and E had the lowest risk of gastric cancer.
"Our findings suggest that high intake of antioxidant vitamins contribute to the reduction of gastric cancer risk and that gastric cancer risk in Korea may be decreased by encouraging those with H. pylori infection to increase their intake of antioxidant vitamins," the study authors conclude.
