Prostate cancer is the second most common cancer diagnosed in men and has increased dramatically in the past two decades partly as a result of lifestyle changes. Indeed, prostate cancer is a disease of the affluent West while Japan has one of the lowest rates of prostate cancer amongst economically developed nations. The traditional Japanese diet may reduce the risk of prostate cancer through a combination of increased soybean products and fish intake, with reduced red meat consumption. Also, the Mediterranean diet, as well as tomatoes and other red and orange coloured vegetables and fruits, may be protective against prostate cancer. While reading the special issue on “Diet and Prostate Cancer” we suggest you relax with a good cup of tea as tea may well play an important role in prostate cancer prevention.
