Yeah calling 1.5L/w 'light moderate' it's a stretch
But anyway, I always take such research with a grain of salt (or maybe with a glass of wine) because alcohol consumption has personal relationship benefits
Also not discounting the possibility that it's another "fat is bad" craze
Then again it's equivalent of 3.5 liters of beer per week. And you don't see people who drink one beer after work and at most two on weekend calling themselves heavy drinkers.
I have always given the research credit that it may just be highly counter intuitive but it has always seemed rather obvious that drinking poison is not part of optimal longevity.
The least shocking thing is for new research to come out claiming no amount of poison is good for you.
I quite enjoy drinking a few times a year but pushing 50 there is nothing that makes me feel as bad as even a few beers the night before compared to getting up and going for my morning 60 min walk without.
Calling it "poison" is not an honest description of it
That "poison" is present in fruits, and there is even evidence that we have evolved to eat fermented foods, containing said substance (which doesn't get metabolized in the best way, sure, but not in the worse way neither).
UV rays are also "poison" and also essential to normal life. Oxygen is literally toxic to several life forms on earth.
Other "poisons" present in food are cyanide for example. Vitamin A is also very damaging at high quantities.
