Resveratrol in Normal Mice

From EurekAlert!: "Scientists have found that the compound resveratrol slows age-related deterioration and functional decline of mice on a standard diet, but does not increase longevity when started at middle age. ... Dietary restriction has well-documented health benefits in mammals, and the study of possible mimetics of it, such as resveratrol, are of great interest. ... Resveratrol did not have a significant effect on lifespan in animals fed standard chow, suggesting that the intervention did not affect all aspects of the basic aging process. Mice on a high-calorie diet without resveratrol lived the shortest length of time and mice on an every-other-day regimen lived the longest, regardless of resveratrol treatment. However, for mice on a high-calorie diet, mean and maximum lifespan increased for mice on resveratrol when compared with the control mice. Researchers found that resveratrol's effects on longevity could be completely uncoupled from changes in body weight, meaning that mice on a high-calorie diet with resveratrol did not necessarily lose weight but did experience a longer (and healthier) life than mice on the same high-calorie diet not taking resveratrol. They speculate that improved cardiovascular health and reduced fatty changes in the liver may have contributed to the increased lifespan of resveratrol-treated mice."
