Is it? There has been a lot of research on stuff like antioxidants in wine but as far as I can tell that's largely because of older observational health studies on purporting to show a positive effect from moderate wine consumption which has disappeared in more recent studies that did a better job controlling for confounding factors (like many people who don't drink at all being former alcoholics or having other health issues) which have shown that any alcohol consumption is harmful.
