"Drinking more than two glasses of red wine per week was associated with a 40-percent reduction in kidney cell cancer risk compared with drinking no red wine, the investigators observed, and there were similar trends for more than two glasses per week of white wine or strong beer.
In contrast, there was no relation between kidney cell cancer risk and consumption of light beer, medium-strong beer, strong wine, or hard liquor.
"A reduced risk associated with consumption of wine and beer might be due to the phenolics they contain as these possess antioxidant and antimutagenic properties," the authors speculate.
"However, the lower risk that we observed for three different alcoholic beverages and total ethanol intake suggests that alcohol itself rather than a particular type of drink is responsible for the reduction in risk."
