Well, all this seems to confirm is that there is some kind of balance. Too much, not good. Nothing, you don’t get any benefits. The studies that said red wine is good for you all had a small glass with dinner, not a huge one.
So, you can thank Mr Science for this:
no glass = no benefits
small glass = good
large glass = bad
As regards the article saying that so many “units” per day were good/bad for you etc, the BMA (Brit version of AMA) admitted a year or so ago that their long touted recommendations were in fact numbers pulled out of a hat and based upon no scientific data whatsoever. They were merely responding to some gov’t request - they want numbers, we’ll give ‘em numbers !!
