Is wine good for you or is it not?
. . . that is not the correct question. The correct question: Is science capable of producing accurate research, at all.
Or to put it another way, are these the same scientist who have been lying to us about cholesterol, the food pyramid, carbs, fats, eggs, bacon, butter, and pretty much everything else for the past many decades?
For any of the scientists involved, how many of their papers have been retracted, or scrutinized for retraction?

Major publisher retracts 64 scientific papers in fake peer review outbreak
Publishers withdraw more than 120 gibberish papers
Have any of the scientists been named by John Ioannidis?
Why Most Published Research Findings Are False
Yes, it has become all but impossible to actually know whether a medical/scientific/academic paper is valuable or gibberish. Based on Ioannidis's statements that about 80% of these papers are wrong/valueless, I simply don't put any stock in them anymore. Make reasonable choices, and ignore the silly scientists, and doctors, and you will be fine.
If you like wine, then, in moderation, it is good for you. If you don't, then, that crap will kill you!
