The theory about moderation being a trait that applies to a person in general makes sense.
However, I think the most health-conscious people today probably don't drink at all due to recent sentiment leaning more toward even moderate drinking being harmful. I also assume their health-awareness would preclude them from replacing alcohol with sugary drinks or other unhealthy options.
So I continue to find it interesting when studies show reduced all-cause mortality for moderate drinkers.
