A study from the University Wisconsin-Madison indicates that even small amounts of resveratrol, a compound found in red wine and some other foods, may help people stay heart healthy and slow down other issues as we age.
Scientists have known about resveratrol for sometime. Most studies showed that large qualities of wine would be needed to get the proper dose of the substance. However, the new tests in mice revealed that low doses of resveratrol have the same impact as lower caloric diets. Some studies suggest cutting calories by 20 to 30 percent can extend a person's life span.
The University of Wisconsin-Madison study indicates resveratrol may reduce gene expression changes that take place as people age.
