"Alcohol consumption" no, defintiely not! Alcohol is a toxin, plain and simple.
However, there have been some studies that show that particular drinks have health benefits that outweight or counteract the drawbacks, depending on how you think about it and depending on who you ask. One standard serving of red wine, for example, is packed with antioxidants, so many folks will choose to have a glass every few days and count it as being healty to do so. Depends on WHICH red wine you drink, of course.
