So basically vegetables, the stuff we already should be eating. Though sure is tempting to think some mysterious chemical in wine is a replacement.

Oops. I don't think the study showed that at all. You have jumped to a conclusion. Maybe it's valid, maybe not.

My grandfather, a wine drinker all his life, suffered severe dementia in his final years. There is no magic bullet.

Anecdotal data is not evidence.

My grandfather smoked 2 packs a day starting when he was 11 till he was 97 and didn't get lung cancer.

It is evidence of N=1.
