Prostate cancer (PCa) is the most common non-cutaneous cancer diagnosed in North America with similar trends in many Western countries. Geographic, epidemiological and laboratory studies suggest a role for dietary constituents in the etiology as well as prevention of Prostate cancer.
The rising incidence of Prostate cancer in several countries appears to be coincidental with adoption of western lifestyle. Increase in the incidence of Prostate cancer has also been found in Asian populations migrating to the west. These facts give numerous leads to explore testable Prostate cancer prevention strategies. There is growing evidence in support of use of dietary ingredients in prevention and treatment of Prostate cancer. While substantial data exists in favor of use of polyphenols from tea as Prostate cancer chemopreventive agent, interest in anti-cancer properties of polyphenols from pomegranate has recently emerged. This review summarizes current literature on the effects of polyphenols from green tea and pomegranate against Prostate cancer.
