Those who support drinking alcohol, including professing Christians, might point out apparent benefits of moderate drinking, both compared either to drunkenness or teetotaling. Recent "studies" have debunked some of those in a significant way. It should make sense to someone.
The simple answer is alcohol gets into the blood stream, goes to the brain, and it kills brain cells. Aaah, but that isn't exactly what happens. No. It's more technical. Alcohol damages some of your neurons, which send electrical and chemical messages within the brain and between it and other parts of the body. There, that's all. To get even more technical, alcohol inhibits the communication between dendrites, or branching connections at the ends of neurons that send and receive information between neurons, in the cerebellum, a part of the brain involved in motor coordination. This means that alcohol, like most know already, is mind-altering.
If you were to try to justify doing what I wrote about in the second paragraph, a good way to do it is to say that a lot of people destroy or harm or hurt their bodies in a lot of different ways, including the brain, so to be consistent, it is permissible to do it with alcohol too. I'm not going to go further with it, but scientific studies have been done recently that show that even moderate drinking of alcohol damages the brain, results in obesity, and affects your immune system in a bad way. The latter isn't good news for future possible coronavirus exposure.
What I have for you below is a bit of a one stop shop with recent articles and studies for the affects of moderate drinking of alcohol for those who believe moderate drinking is acceptable and even helpful. Of course, I believe the Bible prohibits the drinking of any alcohol. No one has to do it. No one should do it.
