I don't know how that could have health benefits.
Well, it doesn't seem so far fetched. Moderate alcohol use could definitely have a stress reducing effect and stress has well documented health impacts. And social drinking could easily have beneficial second order effects from social interaction.
Who knows if this is what's happening, but it's easy to spitball some benefits.
It's not the alcohol (ethanol) that has the health benefits, but the solution it's in. I think it applies mainly to wine, which has a bunch of anti-oxidants
You're probably right, but science doesn't advance by saying, "Let's just assume I'm right, and go from there."
There's a good theory why moderate drinking is still unhealthy (self-exclusion of non-drinkers). There's no proven theory as to why moderate drinking should somehow increase health.
So while it's not perfect science, for the practical purpose of making life decisions, that's enough for me.
There's also a surprisingly strong link between alcohol use and exercise, that persists even when you look at "heavy drinking levels" [0].
In fact, given the fact that alcohol use has such a high effect on certain medical conditions, but such a low impact on all-cause mortality, you can be certain that alcohol use has some strong positive health effects. And it's down to individual circumstances whether the positives are likely to outweigh the negatives.
Sure, but you can have an active social life without consuming alcohol and have the benefits of not drinking AND having an active social life.

Couldn't this be the same fallacy? i.e. the people who don't drink self-exclude from drinking AND exercise because they're sick or injured or whatever?
Or could it be that people who are more active in general just do both things more?
