Diet Synergistically Affects Helicobacter pylori-Induced Gastric Carcinogenesis in Nonhuman Primates

Gastric intraglandular neoplasia is induced in primates when H pylori infection is associated with consumption of a carcinogen similar to the nitrosamines found in pickled vegetables, suggesting that H pylori and the carcinogen synergistically induce gastric neoplasia in primates.
