In a population study involving 525 men under 80 years of age diagnosed with prostate cancer of which 42% died of prostate cancer and another 49% died of other causes. The study found that the higher the dietary intake of zinc the greater association there was with a reduced risk of prostate cancer-specific mortality by 64%. No association was found between zinc intake and mortality from other causes. The authors conclude that, ”…..high intake of zinc is associated with lower prostate cancer-specific mortality after diagnosis, particularly in men with localised disease.”
Greg’s Comments: Zinc is essential for male reproductive health and concentrates in the prostate. It is also regarded as the commander and chief of the immune system and plays a major role in destroying or inhibiting the production of cancer cells.
