Executive Summary
SELENIUM RECOMMENDED INTAKE MAY BE "SUBOPTIMAL" FOR PROSTATE CANCER risk reduction, Kazuko Yoshizawa, Harvard School of Public Health, et al., state in a study in the Aug. 19 Journal of the National Cancer Institute. The researchers report a "strong inverse association between the prediagnostic selenium level assessed" in study participants and the risk of advanced prostate cancer. Higher selenium intake levels among participants, as measured in toenail clippings collected by the researchers, were found to be associated with a lower risk of advanced prostate cancer.
