Dark Chocolate
The flavonols in cocoa can lower your blood pressure by relaxing your blood vessels and thinning your blood. By increasing the flexibility of your blood vessels, it lowers your risk of heart disease. To get the benefits of flavonoids, make sure to get dark chocolate that’s at least 70 percent cocoa. If you’re not sure, get bars that are labeled "pure," "dark" or "unprocessed."
