Another study on red wine

Today I read an article about another study purporting there to be health benefits to drinking red wine.  I feel that such studies as this are highly deceptive.  They get disseminated in the media with headlines about health benefits of red wine.  But the real question should be: Is there any benefit to having red wine versus just having grapes or grape juice?

I think there should be a law that any studies done on the potential health benefits of wines must always include whole grapes and grape juice as well.  What a waste of research, of time and money to go through all the trouble of these studies and not bother to include grapes and grape juice as well.  Why not  include for example muscadine or concord grapes both of which have ultra-high levels of the beneficial phenolics and other compounds?  I’d love to see a study how concord grapes compare against red wines for health benefits.  My intuition tells me the grapes would blow the wine away.

Of course one major problem is that the grapes sold commercially are among the least nutritious varieties.  And this problem is not a medical one.  Why do we live under a system where the food production/distribution system is controlled by these agri-giants which have incentive to sell garbage fruit and vegetables among all the other garbage they sell?
