Anthocyanins are a class of plant pigments responsible for the color of many fruits, including cherries. They also are potent antioxidants, highly active chemicals that have been increasingly associated with a variety of health benefits, including protection against heart disease and cancer.
"It is possible that consumption of cherries and other fruits containing these compounds [anthocyanins] could have a significant impact on insulin levels in humans," says study leader Muralee Nair, Ph.D., a natural products chemist at Michigan State University in East Lansing. "We're excited with the laboratory results so far, but more studies are needed." Michigan is the top cherry producing state in the nation.
Until human studies are done on cherry anthocyanins, those with diabetes should continue following their doctor's treatment recommendations, including any medicine prescribed, and monitor their insulin carefully, the researcher says. The compounds show promise for both the prevention of type 2 (non-insulin-dependent) diabetes, the most common type, and for helping control glucose levels in those who already have diabetes, he adds.
While fresh cherries and fruits containing these anthocyanins are readily available, medicinal products may be the most efficient way to provide the beneficial compounds, according to Nair. It's possible that an
