I'm not a drinker of wine, but I do have a serious question about it.
 
My father passed away of a heart attack a few years ago, and I'm not sure how his parents died so I can't rule out that they went the same way.  I know that these things can be hereditary, so I spoke to the doc and he recommended I take up drinking wine as a way of lowering my chances of heart issues.
 
I have tried to do it but I just can't adjust to the taste, but I read recently that grape juice may have the same effect.  Apparently it has something to do with the levels of polyphenol.
 
I was just wondering if anyone had any more information regarding this?  For example, does it make a difference as to whether or not the grape juice is red or white, or if it's sparkling or not?  Are the polyphenol ratings noted on the bottles themselves, etc?
