I saw among the answers that from the point of view of doctors, drinking is always harmful. Let me copy my answer from a similar question. In short, there will be described the same thing as in the excellent first answer, where the axiom of modern pharmacology is given, which once descended from the mouth of Paracelsus.
At the moment, the international community (and especially this concerns cardiologists), our domestic ones, are repeating: "You need to / you can drink!" We were constantly told about this at lectures, when I was at a conference in Moscow - the same thing. The question is that there are specially verified dosages, in terms of ethanol, 30ml for a man and 15ml for a woman. Such a dose does not cause liver damage, and it is really useful, because alcohol breaks down fats, respectively, it is akin to preventing atherosclerosis. You know, even pathologists say, you open an alcoholic - and the vessels are like a baby's. But the catch is this. First, it should be high-quality alcohol, preferably wine, in terms of ethanol, the permissible dose will not be more than a glass per evening. Secondly, if this dose is not toxic, this does not mean that you can and should drink every day, so you can come to alcoholism, so you should always follow the rule of "golden mean". Drinking a glass of wine at dinner a couple of times a week is not a bad option.
There are also contraindications for this method of preventing atherosclerosis, with gastritis, ulcers, pancreatitis, kidney and liver pathology, and even with a bunch of problems - the question of drinking moderate doses of alcohol is decided by your doctor.
You sit sometimes, tired; thoughts, thoughts, thoughts in the head. It's also cold in the office. Not all kipiai are fulfilled. You think about the future, you look for strength, you argue tirelessly ... And then bam! A friend calls, calls to meet. I came and sat down. Dry red wine. So you sit ... and more joy is already from the anticipation of the first sip. And then the warmth, all relaxed, lively conversations flow into a slow conversation about nonsense.
In moderation, I think it's helpful to have a glass.
As a certain Paracelsus said (the forerunner, for a moment, of modern pharmacology) - everything is poison and everything is a medicine, the question is only a dose. So if, without too much fanaticism, and even a pleasant good drink, which will be given due to your taste pimples or whatever, purkua would not be pa.
One can hardly say anything specific about this. For example, my father often told me that people who adhere to healthy lifestyles more often suffered from strokes and heart attacks than those who allowed themselves to "have a glass." From the point of view of doctors, drinking is harmful, in any case. Personally, I am of the opinion that even if this action is harmful for health, then it is not for the soul :)
