Resveratrol Grape Juice - Benefits and Side Effects
Resveratrol, an ingredient found in grapes and red wine, has often been linked to the explanation regarding the term 'French paradox', the puzzling fact that people living in France suffer less from cardiac diseases, even though they enjoy a higher-fat diet than most Americans do. This has led to research by scientists, and they have now taken an interest in finding how resveratrol might help in extending lifespan of a human.
They hope to use resveratrol grape juice or resveratrol based compound to induce the same effects produced by a severely restricted diet, which is supposed to extend our lifespan. This diet involves low level of caloric intake which activates a class of proteins, called sirtuin which in turn control metabolism; there are few other natural substances capable of activating sirtuin, but resveratrol grape juice is particularly potent at the task of triggering sirtuins.
This new interest that scientists have found in resveratrol grape juice, has been the cause behind several breakthroughs. The researchers at Harvard University have shown that resveratrol grape juice extends lifespan by controlling the activity of a gene linked with aging generally present in all life forms. It has been demonstrated practically that while middle-aged mice which were fed with a diet rich in calories suffered the deadly effects of obesity like metabolic changes enacting diabetes, liver and heart damage, and premature death. Mice which were fed with resveratrol along with the same high-calorie diet actually showed beneficial changes in their physiology, which were found in mice fed with standard diet.
The main reason for all age-related illness is oxidative stress. It is the cause for many disease processes and in aging itself. Resveratrol grape juice shows powerful antioxidant capabilities which are capable of improving human health drastically.
Scientists report that resveratrol grape juice enhances the oxidation rate of dangerous low-density lipoprotein (LDL) and drives out harmful hydroxyl radicals. Resveratrol grape juice also facilitates in maintenance of glutathione levels, one of the body's most essential antioxidants. According to one of the prominent resveratrol investigators, resveratrol grape juice is one of the most effective free-radical filters with many effects capable of affecting not only lifespan but general health in common.
This supplement has the ability to boost health and reduce the rate of aging process affecting many mechanisms like potent antioxidant effects, capability to enhance energy production at cellular level, and the ability to improve patterns of gene expression in the same manner as that of a low calorie-diet restriction would offer.
A word of caution though, few side effects such as increased sensitivity to hot and cold temperatures, increased secretion of acne have been noticed. So it is advised to visit a doctor under such situations.
