Infection with Helicobacter pylori poses a threat to public health in
numerous regions of the world. This bacterium has been linked to a wide range of
stomach disorders, some of which are benign, such as superficial gastritis, while others
are rather serious, including chronic atrophic gastritis, stomach cancer, and peptic
(gastric or duodenal) ulcers. These conditions can vary in severity and cause significant
morbidity in the affected individual. The International Agency for Research on Cancer
designated it as a 'Group I carcinogen' in the year 1994 after concluding that it played a
significant role in the development of stomach cancer. As a result, there has been a
considerable focus on discovering ways to prevent H. pylori infections. In this article,
we discuss the role that H. pylori plays in human gastric disease, with a particular focus
on the impact of dietary agents on preventing infection and on the pathogenesis of H.
pylori.
