Grapes and red wines help beautify human skins and maintain the forever young a, it is ancient and common sense. But how do they achieve those goals? A few years ago, some groups of scientists believe that resveratrol may work. Resveratrol is a natural antioxidant. It can retard aging, prevent cancers and has a big percent in red grapes, red wines and grape juices. Then scientists feed the yeast, nematodes and fruit flies with red wine. It can be found that their lived periods are extended. In these three organisms, resveratrol can activate relative enzymes and may strengthen the effect of extending life with special diets. The resveratrol has not only the previously anti-cancer effects. The latest study shows for the first time that this compound in animals can also be effective and it make a closer step in human studies.

With multiple copies of the yeast Sir2 gene can live longer. Sir2 proteins are a family of proteins called sirtuins, these proteins in humans and other animals there. And researchers want to know whether sirtuins can prolong human life. In a study of vibration in the wine industry, molecular geneticist David Sinclair of Harvard Medical School and colleagues showed that: a red wine ingredient resveratrol is an activator of sirtuin gene, can extend the life of yeast cells. Sinclair said, but to face up to this result - the object is only a test fungus.

To extend the study, the research team determined whether resveratrol and several related components can extend the life span of fruit flies and nematodes. The results showed that resveratrol can extend the life of the nematode 14%. Relevant information on resveratrol and it's a similar glutathione fisetin also extends the life of fruit flies by 29%. And this is not because of the fruit fly diet's sake - the earlier studies have shown that controlling calorie intake will help extend the life of fruit flies. Resveratrol appears to inhibit the heat through and extend the life of the same ways. When the researchers reduced the amount of food rations, if returned to resveratrol, fruit flies do not live longer.

Resveratrol can extend life spans of the organisms which are more complex than the yeast. This discovery is a critical step in human research. The study makes Sir2 became increasingly common factor in people’s diet and life. Research group has begun the experiments on rodents. Source: http://www.cospcn.com
