Resveratrol From Red Wine May Offset Effects of High Calorie Diet

Red Wine Diet?
Red wine and red grapes contain a chemical, called resveratrol, that can offset some of the effects of gluttony, say researchers from the National Institute on Aging, Harvard Medical School, USA. Resveratrol does not seem to be able to get rid of the obesity, but it can lower glucose levels, help your liver and improve your heart.
Studies had already indicated that resveratrol slows down the aging process in some non-mammalian animals. In this study, the scientists wanted to see what the effects of resveratrol might be on mammals.
They had lab rats which were fed 60% calories coming from fat. The rats were obese, had insulin resistance and cardiovascular diseases. The rats were divided into two groups. One group continued to eat 60% of calories from fat, while the other group had the same diet, but with resveratrol added to it.
The rats receiving resveratrol had lower glucose levels, their hearts became healthier, as did their liver tissue. The scientists also noticed that the rats that consumed resveratrol were more nimble on their feet, compared to the other group.
Even though the resveratrol-fed mice did not lose any weight, their health became as good as that of a mouse on a normal diet. Although the non-resveratrol fed mice continued to have a short lifespan, the resveratrol-fed mice lived as long as mice on a normal diet.
The scientists believe resveratrol may activate SIRT1, a gene associated with longevity.
If what happened to the mice could happen to humans, resveratrol could help prevent obese people from developing Type 2 Diabetes, heart disease, cancer and some other illnesses, say the researchers.
