In 1770, colonial Americans drank about 3.5 gallons of alcohol per year - today it’s roughly 2.3.
One thing I learned when visiting an old settlement in Iowa: the settlers of the time made sure to have a constant supply of beer. The rate they consumed beer seemed to mean they’d have a slight buzz throughout many days.
Heavy drinking and all its bad effects were more common back then, but I don't think table beer is the culprit.
If you drank a gallon of 1%ABV beer every day, you'd have 3.65 gallons of ethanol per year. That's not exactly what was happening - binges on whiskey and rum were common, but they weren't constantly buzzed, either.
That much alcohol is going to be bad for a liver no matter how you drink it. I don't think this was healthy. My point is just that there was less inebriation than we suppose when we think about drinking beer with breakfast
That said, the beer was often weak and watered down so any mention of chronic use should be tempered by the strength of the drink.
