I am open to the possibility that moderate drinking is good for healthy people (I am a moderate drinker), but the article discusses evidence that we can measure harm from moderate drinking - there's quite a bit of it in the second half. When we control the other studies properly (eliminate people who were former drinkers, or are abstaining for health reasons), the benefits seem to go away. I also admit that it would take a large amount of evidence to convince me that moderate drinking is beneficial as a counter to my own fear of motivated reasoning: I would like to believe moderate drinking is beneficial, since I do it. Given that fear, and the evidence we have, I find it much more likely that moderate drinking is mildly harmful, and at best, not beneficial.
