According to a recent study done in London, researchers found that drinking cranberry juice may help lower your blood pressure and overall health of your heart. They discovered oligomeric procyanidins, which is a compound that is known to protect your body from a certain blood vessel constrictor that causes heart disease. This special compound was discovered in regular and light cranberry juice cocktail. Red Wine has been known for years to promote heart health. What makes this finding so remarkable is that this is an alcohol-free way to attain the same protection for your heart. This study has clearly identified oligomeric procyanidins as the specific compound that boosts the health of blood vessels. It inhibits Endothetin-1 synthesis, a blood vessel constrictor which causes heart disease. Cocoa and Green Tea also contain oligomeric procyandicins so you have a pretty good selection of beverages to drink if you want to start lowering your blood pressure.
