The professor and his team analyzed three cocoa powders using a model digestive tract designed to simulate normal digestion. The researchers then put non-digestible materials through anaerobic fermentation using human fecal bacteria. Cocoa powder is one of the main ingredients in chocolate, and contains several antioxidant compounds such as catechin and epicatechin, as well as a small amount of dietary fiber.
While both catechin and epicatechin are difficult for the body to digest and absorb, this changes when they reach the colon, as "desirable microbes" take over. "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," Finley said.
Finley also remarked that combining cocoa's fiber content with prebiotics can contribute to overall health and help change antioxidants in the stomach into anti-inflammatory compounds. Prebiotics are food components found in raw garlic, whole wheat flour and other foods humans cannot digest but are heavily favored by gut bacteria.
"When you ingest prebiotics, the beneficial gut microbial population increases and outcompetes any undesirable microbes in the gut, like those that cause stomach problems," Finley said. He also noted that combining dark chocolate with solid fruits such as pomegranates is even more beneficial to health, and is likely the future of the industry.
Another recent study on dark chocolate and heart health found eating the stuff in moderation can reduce the risk of atherosclerosis, or the thickening and hardening of the arteries, by restoring arterial flexibility and preventing white blood cells from sticking to blood vessel walls. The study was conducted by a research team at the Top Institute Food and Nutrition and the Division of Human Nutrition at Wageningen University in the Netherlands and published in The FASEB Journal.
