From the Wine Spectator Internet site May 20, 2005
"Conventional wisdom has held that alcohol was a sworn enemy of the kidneys, the twin organs responsible for filtering impurities in the blood and passing them from the body. However, this belief is being challenged by a new study that has found that a drink or two a day may lower the risk of kidney failure.
The study, published in the May 9 issue of the Archives of Internal Medicine, found that men who consumed at least seven drinks in a week showed a 29 percent lower risk of renal dysfunction than nondrinkers and infrequent drinkers. Men who had five to six drinks a week had an 8 percent lower risk. The study did not distinguish among different types of alcohol."
