The Sweet Benefits of Chocolate

Whatever your chocolate indulgence of choice, the health benefits of chocolate depend upon the type of chocolates you choose – and how many.

The Healthy Insides

Most of the health benefits touted with dark chocolate relate to cardiovascular disease. Dark chocolate is packed with flavonoids, a group of phytochemicals that act as antioxidants. Research shows that consuming chocolate increases the antioxidants in our blood. In one study comparing the antioxidants among chocolate products, cocoa powder ranked as having the highest of the chocolate products, followed by dark chocolate and milk chocolate.

A steady stream of population and lab studies link eating chocolate in moderation with heart health, including improving blood vessel function and lowering blood pressure. The flavonoids can slow the oxidation of LDL cholesterol (the "bad" type). When LDL cholesterol becomes oxidized it can clog blood vessels.

Given chocolate’s rich supply of flavonoids, researchers have also investigated whether it may play a role in cancer prevention. The studies in cancer prevention are still emerging. A recent review of studies on the cancer protective properties of cocoa concluded that the evidence is limited but suggestive. More rigorous studies should be conducted on chocolates’ cancer protective role, concluded the author, because it provides "strong antioxidant effects in combination with a pleasurable eating experience."

From Cacao to Cocoa

Whatever the chocolate, it all begins with the cacao (pronounced kuh-KOW) bean. First, the cacao bean is roasted and ground into a thick chocolate liquor (non-alcoholic). This liquor, hardened, is unsweetened chocolate. When pressure is added to the liquor, it pushes out the bean’s fat, called cocoa butter. Cocoa powder is made by drying and sifting the remaining material from the liquor.

Mix up some chocolate liquor, cocoa butter, sugar and milk, and the commercial chocolate treat emerges. In general, the higher the percentage of cacao, the darker the chocolate and the more intense the flavor. And as cacao content goes up, there’s less room for sugar.

White chocolate contains cocoa butter but not any chocolate liquor; technically it is not chocolate. (It gets its name because it contains cocoa butter.)

Pick Your Pleasure

Of course, there are plenty of ways to get the same healthful plant compounds contained in chocolate, such as by eating fruits and vegetables. And fruits and vegetables can also offer "a pleasurable eating experience." But for chocolate lovers, you can enjoy it all.

Whether it’s dark or milk, aim for the plain chocolates without all the nougat and fillings. Just make sure to look at the calories and serving size. If you incorporate about 1 ounce of chocolate into a diet filled with fruits and vegetables, you’ll be savoring a wide variety of delicious treats – and plenty of health promoting phytochemicals.
