The chemical also sourcing from cranberries, blueberries and peanuts, achieves the effect by blocking the growth of a hormone called oestrogen.

Study findings

Though the thought of chocolate and wine as medicinal almost takes the fun out of it, researchers found both have ingredients that make the minds sharper.

The beneficial effect appears to stem from the high concentration of healthy compounds called polyphenols that are found abundantly in dark chocolates and red wine, and have antioxidant properties.

According to experts, polyphenols open up blood vessels in the human body, which in turn helps the blood to flow more freely to the brain.

The researchers found that resveratrol a natural chemical present in red wine can boost a common breast cancer drug in supressing cancer cells. The discovery was made at the Cleveland Clinic's Lerner Research Institute.

Study particulars
When the breast cancer drug rapamycin was teamed up with resveratrol, the drug was better able to inhibit growing breast cancer cells than when the drug acted alone.
