And yet the study talks about "alcohol related illness like cancer or other injury" (which kind of injury btw? a car accident?) and admits "moderate drinking may protect against heart disease". I need a citation for the "heart protection vs other disease".

Hey, I'm 100% confident that heavy drinking is bad. But very moderate drinking (like, one glass of wine per day, when having dinner), for what I can see, seems to be correlated with moderate people that can limit themselves and yet it helps relaxing, de-stressing, having a chat. All those things are good for somebody's overall mood and health. Stress is bad.

Everything IMHO. I'm not an MD or an expert.
