OK. First, I’m going to mention that I’m Jewish, because statistically, alcoholism is rarer among Jews than other ethnic groups. That does not mean we don’t have alcoholics. We just have a statistically significant number fewer.
What’s interesting, though, is that you also find very few Jews who don’t drink at all. I’m one, but it’s not on principle, it’s for health reasons.
I did used to drink, albeit, never very much. It’s always been my observation that Jews have a sui generis drinking pattern-- any excuse for a shot or a toast, and then maybe nurse another glass of something over the course of a gathering, if there is one, but never more than one.
I know a lot of people who think it has to do with the fact that we’ve had alcohol for a much longer time than other people. I have no idea if there is any actual research behind that, but it would make sense.
So there’s a point for genes.
On the flip side, Native Americans, who have had alcohol for a very short time have a real problem with alcoholism.
FWIW, when I did drink, I never got drunk very fast, but I think part of it had to do with the fact that I don’t like alcohol enough to drink it like Coca-Cola, so it doesn’t get in my system very fast. Most Jews I know drink that way, even college students.
So there’s a little culture behind it as well. We’re used to getting sips of wine at the table, or a teaspoon of wine in a Sprite glass on a holiday. There’s not a lot of mystery around alcohol, and since most of us never saw our parents drunk, we never thought of alcohol as being for the purpose of getting drunk.
So, there’s culture, too.
Just my take.
