The health benefits of dark chocolate are all the rage right now, with increasing numbers of studies pointing to its rich concentrations of beneficial antioxidants and polyphenols.
This applies particularly to dark chocolate because it contains a higher concentration of cacao seeds than milk chocolate, and therein lies the secret to its health-promoting powers.
Cacao refers to the plant, a small evergreen tree of the species Theobroma cacao, which is cultivated for its seeds, also known as cacao beans or cocoa beans. The term “chocolate” refers to the solid food or candy made from a preparation of cacao seeds (typically roasted). If the cacao seeds are not roasted, then you have “raw chocolate,” which is also typically sweetened.
Cocoa, on the other hand, refers to the powder made from roasted, husked, and ground cacao seeds, from which most of the fat has been removed. Knowing the meaning of these terms is important, because if you think you’re improving your health by eating typical chocolate candies, you’re being misled.
That being said, however, certain types of chocolate, as well as cocoa powder and cacao, are turning out to be powerful superfoods that rank right up there among the most anti-inflammatory and antioxidant-rich foods known to mankind.
Your Gut Bacteria Help Unlock Chocolate’s Anti-Inflammatory Powers
Research presented at the 247th National Meeting & Exposition of the American Chemical Society (ACS) claims to have unraveled the precise reason why dark chocolate is so beneficial. While it’s known that cocoa powder is rich in antioxidants including catechin and epicatechin, along with a small amount of fiber, it was thought that these molecules were poorly digested and absorbed due to their large size.
The new study found, however, that your gut bacteria breaks down and ferments the components in dark chocolate, turning them into anti-inflammatory compounds that benefit your health. In particular, beneficial microbes including Bifidobacterium and lactic acid bacteria “feasted” on chocolate, according to the researchers.
The study, which involved three cocoa powders tested in a model digestive tract, may help explain why chocolate has been found to be so good for your heart, as the anti-inflammatory compounds may reduce inflammation of cardiovascular tissue. The study’s lead author explained:
“In our study we found that the fiber is fermented and the large polyphenolic polymers are metabolized to smaller molecules, which are more easily absorbed. These smaller polymers exhibit anti-inflammatory activity… When these compounds are absorbed by the body, they lessen the inflammation of cardiovascular tissue, reducing the long-term risk of stroke.”
What is it about dark chocolate? The answer is plant phenols — cocoa phenols, to be exact. These compounds are known to lower blood pressure. Chocolates made in Europe are generally richer in cocoa phenols than those made in the U.S. So if you're going to try this at home, remember: Darker is better.
