A Chocolate A Day? Chocolate Demystified

Is it true that a chocolate a day will keep the doctor away? That’s what many chocolate companies would like you to believe in their Valentine’s Day advertisements. While it looks like cocoa has many health benefits, the chocolates you buy from your local stores may impart little of those benefits.

 A Rich History

The cacao bean, grown mainly in Latin America, Africa and Asia, is loaded with beneficial compounds. In fact, its early uses, dating back 3,000 years were mainly medicinal. They have ranged from curing fatigue, angina, constipation, dental problems (tartar removal), dysentery, gout, an “overheated” heart, skin eruptions, fevers, and seizures. One doctor in the 1500s found it made people “extraordinarily fat” if used frequently and so it was prescribed for the thin and weak, according to an article in The Journal of Nutrition. It has been highly prized for centuries, which is reflected in its scientific name, Theobroma cacao, meaning “Food of the Gods.”

Eurpoeans discovered cocoa in the 1500s and over the next few centuries, chocolate, which we know and love so well was born. In this century, chocolate (processed cocoa with added fat, milk and sugar) has been enjoyed for its melt-in-your mouth texture and flavor, with its health giving properties largely forgotten by the civilized world, until recently.

In 1997, Harvard professor Norman K. Hollenberg published a landmark epidemiological study focused on cocoa. He found that high blood pressure was a rarity among Panama’s Kuna Indians who also didn’t experience the typical age-related increases. He at first attributed it to genetic protection. But, when the Kunas migrated to Panama City, their blood pressure increased, pointing to an environmental cause. Upon examination, Hollenberg found the Kunas drank large amounts of indigenous, unprocessed cocoa. Subsequent experiments conducted by Hollenberg and others, have found that cocoa, if high in flavanols, the beneficial plant compounds scientists believe impart most of cocoa’s benefits, relaxes the blood vessels, an important protection against hypertension and heart disease.

The Growth of Chocolate Research

Since Hollenberg’s findings, cocoa research has intensified, mainly due to the largess of companies like Mars, Inc, most famous for Milky Ways and M&Ms. What’s striking is that candy companies, such as Mars and Nestle’s, have hired respected nutrition scientists and have been largely responsible for the advancement of cocoa research. Mars has collaborated with such institutions as Harvard, the University of California at Davis, and even the United States Department of Agriculture’s Agricultural Research Service. Through their research and others, many interesting discoveries about cocoa’s health benefits have been made.

The flavanols in cocoa help maintain a healthy vascular system, relax blood vessels, they reduce blood clotting – an aspirin-like affect –reduce oxidative damage, and improve blood flow. A study in the American Journal of Clinical Nutrition found cocoa also reduces inflammation. All of which reduces heart disease risk.

There have been some suggestion that flavanols can be used to treat vascular diseases like dementia, pre-eclampsia in pregnant women, and anything related to blood flow. Emerging research is looking into cancer as well.

But what about that chocolate bar in your vending machine? Are there any health benefits there? The answer: probably not much.

Most research about chocolate’s health benefits have used unsweetened cocoa or specially formulated high-flavanol chocolate. Unfortunately, these compounds are rarely in the chocolate we eat in 21st century America. Flavanols impart a bitter taste so they’ve been removed from most popular products to improve their flavor.

Most of the flavanols are in the cocoa beans and the level decreases with each processing step when it goes from the bean, to the cocoa powder and ultimately a finished chocolate product.

Since flavanols and their health benefits are a new discovery, chocolate companies are just beginning to see if there are ways to keep flavanols consistently high, but still have a tasty, popular product.

Katherine’s Chocolate-for-Health Tips

You’ll get more flavanols, and therefore health benefits, with less processing. The first choice is cocoa, which isn’t Dutch processed – as when cocoa is “Dutch processed with alkali” the flavanols are reduced. Look for chocolate which has the highest percentage of cocoa as possible and to save calories, look for chocolate with lower fat and sugar levels. In general, cocoa is your best first choice. Second choice is a semisweet or bittersweet chocolate with a high cocoa percentage. Some chocolates go as high as 85% cocoa, but legally can be as low as 35%. I recommend no more than an ounce a day, which may be about 110 – 150 calories, depending on the chocolate. Any more than that and you’re probably going to take in too many calories for weight control.

1.3 oz Dark Chocolate Bars, Average*:                    82 mg        187

1.3 oz Milk Chocolate Bars, Average*:                    42 mg         198

1 TBSP Unsweetened Cocoa Powder, Average*:    75 mg        12
