Could it really be true? Can eating chocolate on a daily basis really lower your blood pressure? Researchers say yes, but before you hit the nearest vending machine, read on to find out what kind of chocolate to look for and just how much is beneficial.

New studies suggests that eating dark chocolate may lower blood pressure in people with hypertension, plus, as an added bonus, it may also improve cholesterol levels and insulin sensitivity. Researchers attribute it to the antioxidant-rich compounds, called flavonoids, that are found in cocoa and dark chocolate.

Flavonoids are a group of compounds that are found in the seeds and skins of plants, such as fruits, vegetables and cocoa beans. It is these particular compounds that are thought to be responsible for some of the heart-healthy effects of red wine and diets high in fruits and vegetables. Dark chocolate specifically contains plant substances called polyphenols, which is a type of flavonoid. Researchers believe that these antioxidant-rich polyphenols improve blood pressure by helping the lining of the blood vessels expand and contract more efficiently, resulting in better control of blood flow.

Chocolate is still loaded with fat and sugar and can contribute to weight gain because of its high calorie content. A serving size of 3.5 ounces may have positive results, but eating too much more than that could cause you to pack on some extra pounds. Also, to reap the health benefits of chocolate, look for dark, bittersweet chocolate with a high cocoa content. Bear in mind that milk chocolate candy bars lose much of their flavonoids during processing.

In conclusion, yes, dark chocolate can be a beneficial part of your healthy diet, but choose wisely and watch your portion sizes.
