46. A wine-derived compound called quercetin improved liver and pancreas function in diabetic rats. Although resveratrol has received a lot of attention as an anti-diabetes therapy, this study showed how other wine polyphenols help too.
47. A form of quercetin called Q3 was tested for anti-flu viral activity and found to be more potent that oseltamivir (Tamiflu) according to a recent study from Korea. This provides further support to findings that wine drinkers have fewer colds and flu.
48. A study from Brazil evaluated the effect of wine polyphenols on a type of brain cancer called glioma. They found that resveratrol and quercetin together had a synergistic effect on inhibiting cancer cell growth.
49. And to further the idea that resveratrol isn't the only good thing in wine, another study looked at the effects of quercetin on the inflammatory effects of exercise on muscle. This is an important study because it is one of the few clinical studies reported. They found that quercetin supplementation reduced inflammatory markers after 3 days of intense exercise in trained cyclists.
