GAINESVILLE, Fla. A University of Florida review of research finds the polyphenol compound known as resveratrol found in red wine, grapes and other fruits may not prevent old age, but it might make it more tolerable.
News stories have long touted resveratrol as a cure for various diseases and a preventative against aging.
"We're all looking for an anti-aging cure in a pill, but it doesn't exist. But what does exist shows promise of lessening many of the scourges and infirmities of old age," said UF exercise psychologist Heather Hausenblas, one of the researchers involved in the study.
A comprehensive review of human clinical research on resveratrol has found it has "anti-aging, anti-carcinogenic, anti-inflammatory and antioxidant properties," but more research of its benefits is needed, she said.
The study, which appeared online this week in Molecular Nutrition and Food Research, examined results gleaned from thousands of laboratory studies with enzymes, cultured cells and laboratory animals. It was conducted by Hausenblas and fellow researchers James Smoliga of Marywood University and Joseph Baur of the University of Pennsylvania School of Medicine. Their review aimed to examine the current state of knowledge of the effects of resveratrol on humans and to use this information to guide much needed future human clinical trials.
Despite numerous clinical studies on resveratrol's tonic effects on animals, there is little evidence that it benefits human health. That's because "there haven't been many studies on humans," Hausenblas said.
However, she points out, for years many scientists have thought that a link between resveratrol and human health exists. The French people, for example, enjoy low levels of cardiovascular disease, even though their diets are rich in saturated fats and oils. Some researchers think the reason for this paradox lies in France's national drink red wine, which is the most i
