Beer reduced kidney stone risk by 41%.Not only beer, but apparently my fondness for caffeinated coffee may prove to be a good thing in the long run. Another interesting finding in the report is that diet colas did not appear to increase the risk, although diet non-colas and sugar-sweetened colas did.
White wine reduced risk by 33%.
Red wine reduced risk by 31%.
Caffeinated coffee reduced kidney stone risk by 26%.
Decaf coffee reduced risk by 16%.
Orange juice reduced risk by 12%.
Tea reduced risk by 11%.
The researchers theorize that the diuretic effect of caffeinated and alcoholic beverages is a contributing factor in their benefits. So perhaps the healthful conclusion is to not fret about those frequent beer-induced bathroom breaks.
