Health Watch - Diabetes: Grapes

Health Watch is a Public Service of the Office of News and Publications and is intended to provide general information only and should not replace the advice of a medical professional. You should contact your physician if you have questions about any of these topics.

This week on Health Watch, we’re talking about research into diabetes. You may have heard that substances made from grapes – like red wine – are good for your heart. They may also help protect against diabetes.

Researchers at UT Southwestern Medical Center have found that a substance found in grape skins lowers insulin levels in mice when it’s injected directly into the brain – even if those mice eat a high-fat diet. Dr. Roberto Coppari, the UT Southwestern researcher who led the study, says this doesn’t mean you should drink a lot of red wine.

This substance doesn’t cross the barrier between the blood and the brain, so it has to be injected directly into the brain to take effect. Researchers believe it affects certain proteins in the brain to help manage insulin levels. They plan more research to determine exactly how it works and then to use this knowledge to possibly develop treatments for diabetes.
