Chocolate

  Chocolate may improve blood flow - if you eat the right kind. Studies suggest the flavanols in darkchocolate may curb levels of bad cholesterol, improve circulation, and keep blood pressure in check. Men with poor blood flow are more likely to develop erectile dysfunction, so heart-wise foods may protect your sex life, too. But too much chocolate can lead to weight gain. Bonci suggests eating one ounce a day in lieu of other sweets.
