Well in rat experiments a little bit of alcohol in their water makes them live longer. The supposed mechanism is that alcohol helps keep intestinal bacteria in check and reduces endotoxin absorption. There are various other reasons to think that in most people light alcohol intake is protective. I don't think wine has anything to do with it. The safest drink would be a high quality vodka.
