Low doses of a red wine ingredient fight diabetes in mice

Even relatively low doses of resveratrol—a chemical found in the skins of red grapes and in red wine—can improve the sensitivity of mice to the hormone insulin, according to a report in the October issue of Cell Metabolism. As insulin resistance is often characterized as the most critical factor contributing to the development of type 2 diabetes, the findings “provide a potential new therapeutic approach for preventing or treating” both conditions, the researchers said.
