I believe one glass of red wine a day is supposed to help ward off either heart disease or cancer. I'm not sure on that.
It's heart disease, yes, but iirc it's an effect limited to red wines grown in certain areas. Something about soil composition. Cheap shit you buy in an American liquor store probably won't have quite the same effect. S'more likely to be found in European stuff, so far as I'm aware, and that's where the studies I've ran into produced notably positive results.
I've chimed in on alcohol use a number of times, so no real need to repeat m'self, I guess. I will say that, for folks uninterested in the stuff,
never feel pressured to consume alcohol. You are under no true obligation to imbibe a mood altering poison, nor are you missing out on anything truly substantial. If you don't want to,
don't. You're in no way lesser because of it.
