Grape juice is high in other antioxidants, while the alcohol in wine has been shown to raise 'good' cholesterol.

There is no evidence that it would provide these benefits as part of a normal diet — even for wine drinkers. It is not a simple matter to extrapolate the results of yeast studies to human health, especially when the studies on yeast used much higher concentrations of resveratrol than are available from wine drinking. Levels of resveratrol in wine are generally less than 5 mg per l, and it is heavily metabolized during the absorption process, resulting in extremely low plasma concentrations (D. M. Goldberg et al. Clin. Biochem. 36, 79–87; 2003).Anonymous Cowardhttps://www.blogger.com/profile/13315733940344340689noreply@blogger.comtag:blogger.com,1999:blog-14815894.post-61485614349708816592007-04-11T10:52:00.000-04:002007-04-11T10:52:00.000-04:00"The resveratrol content of wine is related to the..."The resveratrol content of wine is related to the length of time the grape skins are present during the fermentation process. Thus the concentration is significantly higher in red wine than in white wine, because the skins are removed earlier during white-wine production, lessening the amount that is extracted [3]. Grape juice, which is not a fermented beverage, is not a significant source of resveratrol. A fluid ounce of red wine averages 160 µg of resveratrol, compared to peanuts, which average 73 µg per ounce [6].
