Kidney stones are intensely painful and overwhelmingly afflict men. A study in 2011 showed that drinking one beer per day reduced the risk of developing kidney stones by 40%, primarily because the high water content helps keep kidneys clean and in working order. Drinking beer can also temporarily expand the tubes between the kidneys and the bladder, which might help a stone exit less painfully. In Poland and the Czech Republic, there’s even a “medical beer” program. If you drink beer to treat urological condition, the government will refund the money you spend on beer.
