Seems most likely to me that, like many things, alcohol probably has both beneficial and detrimental effects. Additionally, different substances are going to effect different people in different ways and to different degrees. Hypothetically, let's say a substance raised your chance of cancer, but lowered your chance of a heart attack. Is that substance, "good for you"? Would it be good for those (on balance) who were predisposed to having heart attacks, but (on balance) bad for people who weren't? The more studies we do the better, but it is rarely as simple as "good for you" or "bad for you".
