It’s not that you’re supposed to become intoxicated, just that some studies say moderate alcohol can be beneficial. And not only wine. First time I heard of it, the study involved Scandinavians and vodka.
There is a lot of controversy though. For example, some people suggest that the socio-economic level of the people studied had more to do with their health than the alcohol they consumed. But the gist is that a little bit is not such a bad thing.
From the Mayo Clinic:
Moderate alcohol consumption may provide some health benefits, such as:
- Reducing your risk of developing and dying from heart disease
Possibly reducing your risk of ischemic stroke (when the arteries to your brain become narrowed or blocked, causing severely reduced blood flow)
Possibly reducing your risk of diabetes
And of course there are studies claiming just the opposite. You may get some cardio benefits, but you increase your cancer risk, etc.
I’m not advocating one way or another. One of the big problems is that most of the “studies” are based on self-reporting. Last year there was a big splash when someone came out with a review of all prior research and announced that any alcohol at all is harmful. But that was quickly criticized. So who knows?
BTW, as far as drunk driving, I’m with you, but I’m thinking that more and more it’s texting and driving, and just as bad, Google Maps and driving.
Anyhow, here are a few studies if anyone cares. There are plenty of them should you want to look around:
