This review summarizes the mechanistic and clinical research on the use of cranberry as an alternative management strategy for H. pylori bacteria in populations at high risk for infection-induced peptic ulcers and gastric cancer. The multiple mechanisms of action of cranberry polyphenols and how they may be applied in relation to what is known about the pathogenicity of H. pylori offers opportunity for utilizing this fruit to potentially help lower the incidence of ulcers and concomitant gastric cancer
