Thanks. Interesting.
In France, where I am, awareness campaigns recommend sticking to a maximum of 2 glasses per day, for men, 1.5 for women. and not every day. And these values only take into account protection against serious health problems, such as stroke, not the problems of moderate daily alcohol consumption, such as for example the fact that alcohol being a depressant, consumption will have a impact on their general well-being.
To be honest, I'm even more confused on what to think about this paper.
