Summary
A cup of cherries may be the right prescription for people with diabetes. New research shows that chemicals found in cherries could lower blood sugar levels for diabetics. The study found the chemicals, known as anthocyanins, can cause insulin production to jump by as much as 50 percent. Researchers say they’re excited about the results, but more research is needed.

Perhaps George Washington wouldn't have chopped down his father's cherry tree if he knew what chemists now know.
They have identified a group of naturally occurring chemicals abundant in cherries that could help lower blood sugar levels in people with diabetes.
In early laboratory studies using animal pancreatic cells, the chemicals, called anthocyanins, increased insulin production by 50 percent, according to a peer-reviewed study scheduled to appear in the Jan. 5 issue of the American Chemical Society's Journal of Agricultural and Food Chemistry.
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.
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.
Scientists in Nair's laboratory have even developed a unique process, patented by the university, for removing sugar from fruit extracts that contain
anthocyanins.
