Beer may help keep bones strong because it is a rich source of dietary silicon, which contributes tro bone mineral density, a new study has reported. However the amount of silicon apparently varies depending on the type of beer.
The factors in brewing that influence silicon levels in beer have not been extensively studied,’said study author Charles Bamforth, a professor in the food science and technology department at the University for California, Davis, in a news relase from the Journal of the Science of Food and Agriculture. The study is published in the journal’s February 2010 issues. We have examined a wide range of beer styles for their silicon content and have also studied the impact of raw materials and the brewing process on the quantities of silicon that enter wort and beer’ Wort is liquid extracted from the maching process during the brewing of beer. One hundred commercial beers were tested and their silicon content ranged from 6.4 to 56.5. milligrams per litre. “Beers containing high levels of malted barley and hops, which are rich in silicon, ‘Bamforth said,’ “ wheat contains less silicon than barley because it’s husk of the barley that is rich in element. While most of the silicons remains in the husk during brewing, significant quantities of silicon. Nonetheless are extracted into wort, and much of this survives into beer’.
