Red wine compound may boost memory

A substance found in red wine and dark chocolate may improve memory, a new research has claimed. Researchers found that participants in a study of overweight adults who took resveratrol supplements for six months had better short-term recall than their counterparts who took a placebo.

The participants who took the supplement also had more connections among brain areas involved in memory, and this parallelled improvements over the study period in their ability to break down sugar in the body, researchers found.

The study is the first to show a link between the red wine compound and cognition in overweight adults, said Veronica Witte, a neuroscientist at the Charite-Universitatsmedizin Berlin in Germany.
