I wouldn't trade my diet for the diet of a roman. The estimated 500ml wine/daily is very high.

Less than a bottle/day. Not something I do but not something I wouldn't do either.

Your dad might not be the best example of a healthy lifestyle.

Because they (and many other people) drank more than that, doesn't mean it's a good diet. The Romans drank they wine cut with water though I think.

Roman wine was heavily diluted though, at least.

The 500ml is the undiluted amount [0].

Yes maybe it is more like a pint of weak beer per day by modern alcohol standards. Not great for you but maybe a good source of clean water.

German breweries gave their workers an allowance of 4 to 8 liters of beer per day not too long ago. ('Haustrunk')

Often when the conversation of drinking comes up it becomes a contest to see who can drink the most. The WHO actually keeps track of this data on a population level[0]. Right now the country with the highest alcohol consumption per capita is Romania, with an average consumption of >2.9 units of alcohol a day for the entire population 15 years old or older. In case there is some national pride in your comment about Germany, rest assured they are 5th place. I'll leave the readers to decide if that is an enviable position.
