(CBC.CA) — Resveratrol, a chemical found in red wine and dark chocolate, may work differently in the body than first thought, a new study suggests.

“Resveratrol has potential as a therapy for diverse diseases such as Type 2 diabetes, Alzheimer’s disease, and heart disease,” said lead study author Dr. Jay Chung, chief of the National Heart, Lung and Blood Institute’s laboratory of obesity and aging research in Bethseda, Md.

“However, before researchers can transform resveratrol into a safe and effective medicine, they need to know exactly what it targets in cells,” he added in a release.
