I don't think that the "I drink wine because it is healthy", is the main driver of people's drinking--not even the fifth.
After all, I have yet to see a sober person picking up drinking wine because it is good for their health.
Let's have a sober conversation on this: I drink a glass or half a glass of wine most nights because I like it.
I think some people who like wine, would drink less often if they considered it bad for you. But since "it's good" you might as well drink every night.
I have never heard of them, those are the mythical beings nobody has ever seen.
If it were true, the opposite would be likely true as well (I don't like red wine, but I drink if because it is good for my health).
The negative effects one could operate on are putting on weight, not sleeping as well at night, bad breath, sleepiness, but not a fear-mongering article in which it is said that any amount of alcohol increases the risk of dementia.
I am talking about a glass of wine; if the current regime is a bottle of wine a day, the whole equation changes.
It's the same as cigarette taxes, abortion laws, and so on. People claim nobody changes their mind because of it, but statistically the impact is significant.
You cannot compare the cigarette tax to a study saying that even minimal alcohol consumption increases the risk of dementia. If you increase the price of wine 5x, I am sure fewer people would drink, but that's a very wild extrapolation, context-wise, of this conversation.
The same applies to abortion laws: not even in my wildest dreams would I compare their effects on abortion rates to the effects on behavior that the results of the study discussed in this thread would cause.
I guess I was imprecise with my language and did not think about the father-in-law effect. He surely responded extremely quickly to the study just published. However, I would advise waiting for further studies, replications, etc.
Let me rephrase it: I doubt that the results of this study will change the minds of a significant number of people who enjoy drinking a glass of wine every now and then.
