Rats On Wine: Wine Supplementation? Take Your Vitamin W?

Posted On February 25, 2011

Dietary supplementation with polyphenols from red wine may slow the decline in vascular function associated with age, suggests a new study with rats.

Animals fed red wine polyphenols were found to have less dysfunction of the endothelium – the cells lining blood vessels – as well as an improved ageing-related decline in physical exercise, according to findings published in Biochemical and Biophysical Research Communications.
Endothelial function naturally and gradually decreases over time, and it has been linked to range of age-related diseases, especially cardiovascular disease (CVD).
“The present findings indicate that regular intake of red wine polyphenols starting at a young age reduces the endothelial dysfunction and the impaired physical exercise capacity at an advanced age,” report researchers from the University of Strasbourg in France.

This is actually a good study, because when they say that these animals have wine supplementation, they are not talking about “resveratrol” pills — very hot now as the latest greatest miracle pill. 


These researchers actually added red wine polyphenols to ethanol (alcohol) itself, compared to a control group which received alcohol alone with out the red wine polyphenols. Don’t get me wrong, alcohol does good things for you on its own, by inhibiting platelet accumulation along your artery walls. But, in combination with the stuff that’s in red wine, it multiplies the helpful effect on your arteries. 


Get this!! Weird, but true … the animal with the most red wine polyphenols also had a greater endurance in exercise tests!! Go figure. Can you see companies popping up pre-race “wine bars” in the not too distant future? 🙂
