Resveratrol zinvol bij overgewicht en diabetes?

Resveratrol, een stof die we eerder bespraken en die in wijn zit, lijkt ook bij patienten met overgewicht en diabetes zinvol te kunnen zijn. In het tijdschrift ScienceNews lezen we: A naturally occurring chemical found in grapes and other foods may help reverse some of the ills associated with aging and being overweight, new studies suggest.

Het gaat alleen maar om twee kleine voorlopige studies, maar de resultaten zijn wel boeiend:

Now, researchers have found that resveratrol improves the response to insulin in overweight people with insulin resistance and older people with mild insulin resistance. The older people in the study were an average age of 72.

People in the two studies took supplements containing resveratrol at concentrations much higher than are found in food “or even several bottles of wine,” says Jill Crandall, an endocrinologist at the Albert Einstein College of Medicine in New York City.

“We’re encouraged by these results, but do have to stress that they are preliminary.” Crandall presented the results of the two studies in Anaheim, Calif., June 27 and June 28 at a meeting of the American Diabetes Association.
