Resveratrol May Improve Metabolism
Resveratrol - the antioxidant found in red wine - may be as effective for improving energy metabolism as reducing caloric intake, according to a new study from researchers at Maastricht University in the Netherlands. The study was published in Cell Metabolism on October 27, 2011.
The study included 11 obese men who consumed either 150 ml of resveratrol or a placebo daily for 30 days. At the end of those thirty days, the researchers performed no interventions for four weeks and then repeated the test with the original placebo group taking the supplement and the supplement taking the placebo.
The researchers measured metabolic rate, fat storage, fat burning, blood sugar levels, and blood pressure throughout the study. At the conclusion they found that resveratrol resulted in lowered total calorie expenditure and better measures of metabolism and overall health.
Specifically, they noted lower insulin levels, lower blood glucose, less fat in the liver, enhanced mitochondrial function, and lower markers of inflammation. They also observed that the supplement group showed less energy expenditure during sleep, which means their bodies were working more efficiently. This is also seen when a person is on a calorie restricted diet.
Resveratrol has been the subject of a number of studies recently that have shown it to be a powerful antioxidant with many health benefits. These include increasing energy levels, regulating blood glucose levels in diabetics, better brain health, lower risk of lung cancer, improving metabolism, and improved liver function.
This powerful antioxidant can be found in red wine, grapes, grape seed extract, and peanuts. A glass of red wine a day can provide a good amount of resveratrol, but excess drinking will reverse the positive health benefits. Another good way to get resveratol is through a high quality supplement.
