 Notable Note

Scientists have found that eating dark chocolate appears to improve the function of important cells lining the wall of blood vessels for at least three hours. In a study, they found that eating dark chocolate seemed to make the blood vessels more flexible, which helps prevent the hardening of the arteries that leads to heart attacks.
