Not all sugars are created equal. In a dry red wine, most of the fructose is gone, replaced with alcohol. Fructose is what causes most of the problems.
There's plenty of broscience to go around, I only eat roughly 1800s era quantities of sugar per year, compared to the American average being about 150 pounds/yr, so along with a bunch of people I say "zero" in general conversation but in reality its about 5-10 pounds/yr. Well under 10% the sugar consumption of "average american" so close enough to zero. But yeah I'll probably eat some kind of sugar until I die, just practically none. Last week I had a piece of family members birthday cake, how you folks eat that kind of stuff mystifies me, I practically puked it was so sickly sweet and the frosting was like a scoop of Crisco.
