Chocolate is good for your heart, skin and brain. Usually, people think that chocolate is bad for their health. They describe chocolate as “something to die for” or say “death by chocolate”. Now they should bite their tongues! Evidence(证据) is showing that some kinds of chocolate are actually good for you in the following ways:

A happier heart

Scientists at Harvard University recently examined 136 studies on cocoa—the main ingredient in chocolate and found that it does seem to strengthen the heart. Studies have shown heart benefits from increased blood flow. These benefits are the result of cocoa’s chemicals, which seem to prevent both cell damage and inflammation(炎症).

Better blood pressure

If yours is high, chocolate may help. Jeffrey Blumberg from Tufts University recently 

found that people with high blood pressure who ate 3.5 ounces of dark chocolate 

per day for two weeks their blood pressure drop quickly.

Muscle magic

Chocolate milk may help you recover after a hard workout(锻炼). In a small study at Indiana University, people who drank chocolate milk between workouts did better on a tiredness test than those who had some sports drinks.

Better for your skin. German researchers gave 24 women a half-cup of special cocoa every day. After three months, the women’s skin was moister(滑润的)and smoother. The research shows that chocolate helps protect and increase blood flow to the skin, improving its appearance.

Brain gains

It sounds almost too good to be true, but research suggests that chocolate may improve your memory, attention span, reaction time, and problem-solving by increasing blood flow to the brain.
