Interesting, and I think I may have misread the conclusion (or your version thereof), to wit: it does not conclude that drinking up to 2 units per day is good, but that non-drinkers are worse off than people who drink up to 2 units per day - a figure which probably includes more than a few people who drink once every few days or even every few weeks (as opposed to none at all). It also does not differentiate within that group those who drink wine vs. other alcohols.

I hold the result inconclusive, then, on the subject of alcohol itself. Good info, though, thank you!
