Resveratrol May Help with Insulin Resistance
A new study by researchers at the University of Pecs, Hungary shows scientific evidence that resveratrol may have anti-diabetes properties. The study was published in the April 2011 issue of the British Journal of Nutrition.
Resveratrol is a powerful antioxidant found most abundantly in grape skins. It is also present in cranberries, blueberries, and raspberries, but in smaller amounts.
For the study, the researchers recruited 19 people with type-2 diabetes. The participants were randomly assigned to receive two 5 milligram doses a day of a resveratrol supplement or a placebo for 4 weeks.
After four weeks of supplementation, the participants given the resveratrol saw a significant decrease in insulin resistance compared to the placebo group.
The researchers believe this decrease is related to the antioxidant activity of resveratrol. Oxidative stress has been shown by several studies to be a driver of insulin resistance, and antioxidants combat oxidative stress.
A number of studies have shown that resveratrol can provide a variety of health benefits. These include increasing energy levels, better brain health, lower risk of lung cancer, improving metabolism, and improved liver function.
It is important to note that while wine is an excellent source of resveratrol, these findings should not be taken as an excuse to drink more alcohol. Drinking 1-2 glasses per night appears to provide significant health benefits. Once you get beyond that, those benefits are quickly offset.
