Green Tea

Added Kumar et al. as reference 39.

Added level of evidence 1A.

Selenium

Added text to state that an international collaboration compiled and reanalyzed data from 15 studies that investigated the association between blood and toenail selenium concentrations and prostate cancer risk; in the analysis of 6,497 men with prostate cancer and 8,107 controls, blood selenium level was not associated with the risk of total prostate cancer, but high blood selenium level was associated with a lower risk of aggressive disease; toenail selenium concentration was inversely associated with risk of total prostate cancer, including both aggressive and nonaggressive disease (cited Allen et al. as reference 46).
