| In a population-based cohort study involving 525 men under 80 years of age diagnosed with prostate cancer, out of which 42% died of prostate cancer and 49% died of other causes, high dietary intake of zinc was found to be associated with a reduced risk of prostate cancer-specific mortality (HR=0.64), with a stronger association found in men with localized tumors (HR=0.24). No association was found between zinc intake and mortality from other causes. The authors conclude that, "... high dietary intake of zinc is associated with lower prostate cancer-specific mortality after diagnosis, particularly in men with localized disease." | Reference: | "Dietary zinc and prostate cancer survival in a Swedish cohort," Epstein MM, Kasperzyk JL, et al, Am J Clin Nutr, 2011 March; 93(3): 586-93.
