Resveratrol Seen to Boost Quality of Life
Posted on: Thursday, 3 July 2008, 21:00 CDT
A compound found in red wine -- resveratrol -- was found to improve the quality of life of aging mice, but not lengthen their lives, U.S. researchers said.
David Sinclair of Harvard Medical School and Rafael de Cabo of the National Institute on Aging placed 1-year-old mice on a standard control diet or every-other-day feeding with or without resveratrol.
Resveratrol produced changes in the gene expression profiles of key metabolic tissues, including liver and muscle, that closely resemble those induced by dietary restriction, the researchers said.
The study, published online in Cell Metabolism, said overall, the animals' health improved under all dietary conditions, as reflected by a reduction of osteoporosis, cataracts, vascular dysfunction and declines in motor coordination. However, the mice lived longer only when they were fed a high-calorie diet, the study said.
In conclusion, long-term resveratrol treatment of mice can mimic transcriptional changes induced by dietary restriction and allow them to live healthier, more vigorous lives, the researchers said in a statement.
In addition to improving insulin sensitivity and increasing survival in -- high-calorie fed -- resveratrol improves cardiovascular function, bone density and motor coordination and delays cataracts, even in non-obese rodents.

Posted by Jim Hagan on 07/04/2008, 01:49 Resveratrol can help you to lead a long and healthy life so says Dr. Oz. Red wine alone does not supply enough resveratrol to achieve the full range of benefits.You need to take supplements to achieve the results documented in scientific studies. Resveratrol Supplements can also help you control your weight naturally by increasing energy, reducing cravings, and limiting your appetite. According to Wikipedia, Consumer Lab, an independent dietary supplement and over the counter products evaluation organization, published a report on 13 November 2007 on the popular resveratrol supplements. The organization reported that there exists a wide range in quality, dose, and price among the 13 resveratrol products evaluated.
