Most likely you have heard about the anti aging effects of resveratrol a lot lately. Constant news about resveratrol as a medicine for various diseases and a preventative substance against aging have appeared widely. Are these encouraging statements based on scientific data?
Resveratrol was first mentioned in 1939 by Japanese M. Takaoka. However, the substance received wider attention only in 1992, when its presence in wine was suggested to be the reason for heart health boosting qualities of this drink.
The Sources of Resveratrol
Resveratrol is produced in certain plants: red grapes, the fruit of the mulberry. Cocao powder and dark chocolate also have low levels of resveratrol.
In spite of the fact the French people consume a lot of saturated fats and oils, the nation have low levels of cardiovascular disease. Some researchers think the reason for this paradox lies in France’s national drink — red wine, a dietary source of resveratrol. Red wine contains between 0.2 and 5.8 mg/L, depending on the grape variety, while white wine has much less, because red wine is fermented with the skins, allowing the wine to extract the resveratrol, whereas white wine is fermented after the skin has been removed.
Resveratrol has also been produced by chemical synthesis or by biotechnological synthesis and is sold as a nutritional supplement.
How Does Resveratrol Work?
It is not yet fully understood how exactly resveratrol works.
At present the effects of resveratrol are a subject of numerous animal and human studies. In mouse and rat experiments, anticancer, anti-inflammatory, blood sugar-lowering and other beneficial effects of resveratrol have been reported. These results, however, have yet to be proved in humans.
A new meta analysis on resveratrol was recently carried out at the University of Florida. The results were published this summer. This analysis has demonstrated anti-aging, antioxidant, anti-inflammatory and anti-carcinogeric effects of resveratol.
The study examined results gathered from thousands of laboratory studies with enzymes, cultured cells and laboratory animals. The goal of this review was 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.
The research of the University of Florida shows resveratrol has considerable potential to positively effect human organisms.
”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 Heather Hausenblas, one of the researchers involved in the study.
The good news is — resveratrol may not prevent old age, but it might make it more tolerable.
For years many scientists have thought that a link between resveratrol and human health exists. The University of Florida review shows that the resveratrol has considerable potential to improve health and prevent chronic disease in humans. However, further research on the long-term health effects of resveratrol is needed.
