Selenium may prevent prostate cancer

Taking selenium supplements may help reduce the risk for prostate cancer, according to a review study published in the American Journal of Clinical Nutrition.

Susan J Fairweather-Tait of Norwich Medical School Norwich in Norfolk, United Kingdom and colleagues meta-analysed data from 13,254 participants and 5007 cases of prostate cancer in twelve studies and found sufficient selenium was associated with nearly 70 percent reduced risk for prostate cancer.

Increased serum selenium levels up to 170 ng/mL were associated with reduced prostate cancer risk. Three high quality studies of toenail selenium and prostate cancer risk showed a 71 percent reduction in the risk in men with a toenail selenium concentration between 0.85 and 0.94 ug/g.
