Beer Is Good Source of Silicon for Bones, Says New Study

A recent study has reportedly “confirmed that beer is a very rich source of silicon,” a dietary nutrient that increases bone mineral density. Troy Casey and Charles Bamforth, “Silicon in Beer and Brewing,” Journal of the Science of Food and Agriculture, February 2010. According to researchers with the University of California’s Department of Food Science and Technology, pale ales made from barley grist contained more silicon than non-alcoholic beers, light lagers and wheat beers, “likely because of the high levels of silica in the retained husk of barley.” Of the commercial beers sampled, silicon content apparently ranged from 6.4 to 56.5 milligrams per liter. “During brewing the vast majority of the silicon remains with the spent grains; however, aggressive treatment during wort production in the brewhouse leads to increased extraction of silicon into wort and much of this survives into the beer,” the study concludes.
