or are some of the benefits derived from the alcohol? because as far as l am aware alcohol only has negative effects on body, except maybe making you a little bit more relaxed for those of a nervous disposition
ie, is there any health benefit to the alcohol content? or we better off just eating red grapes?

Really a technical question (for which the Internet will provide detailed and technical Answers); followed by an observation. But hang on, I`m on YOUR side – certainly as far as almost anything will do some people some good.

I had always understood that the benefits of red wine had been attributed to TOXINS therein -what do I know? other than that my doctor recommended the stuff after my heart attack- but, in truth, the various do`s and don`t we are given these days are seemingly based on various studies of various groups of people, usually with some pre-existing `condition` which was the reason the group was studied in the first place. On a practical level, almost all such recommendations to-day seem to contradict an earlier finding anyway; so ultimately, you pays your money and you takes your pick.

MY doctor, incidentally, more recently advised that, perhaps marginally less so than red, but even white wine -IN MODERATION- was `good`. All I know is that, an ex-pat British citizen, now living in Portugal, I`ve had far more exposure, access and ingestion of wine in the past six years than the previous sixty, and I don`t feel ANY worse for it.

Do your thing; and enjoy.
