Alcohol is a toxic junk food in liquid form.
That's somewhat true.
But did you know that beer was actually considered a form of "food" in ancient Egypt? Archaeological work shows it was provided to the workers on the pyramids, and other great monuments. Along with fish, since these sites were usually near the Nile River at the time.
It's surmised that since beer is made from grain, the Egyptians thought it must be nutritional, like bread. And beer containing alcohol was safer to drink than river water, that might contain parasites and other pathogens, about which they had little understanding. They could only observe the sickening results.
The reliance upon alcohol as a "safe" drink continued until fairly modern times.
