Well, I am not American and I am still avoiding alcohol altogether. I don't drink regularly anyways - maximum 2 drinks a month, plus sometimes for cooking. There can be positive effects from drinking red wine, but there are also certain risks that increase tremendously. I just read a study the other day, that emphasized how imported it is to avoid alcohol especially in the first trimester, to avoid developmental issues.
Of course one cannot reduce all risks and life needs to go on. Giving up alcohol is so easy for me, maybe someone who has a harder time doing so, will feel miserable during their pregnancy, which in turn is also not considered good for the baby.
Find your own middle way and do things in moderation. I easily give up the wine, but I am not giving up the sushi completely
