Chocolate Is Healthy

While it was generally known that foods rich in flavanols like chocolate are good for heart health, this study in the Proceedings of the National Academy of Sciences established a direct link between flavanol-rich chocolate and cardiovascular benefits.

“The study relied on volunteers from the Kuna Indians, who live on the San Blas islands off the coast of Panama. High blood pressure and other signs of cardiovascular disease are rare among the Kuna. And they are known to consume large amounts of flavanol-rich cocoa—three to four cups a day.

Previous studies found that Kuna who migrated to the suburbs of Panama City on the mainland drink only about four cups of cocoa per week and do not enjoy the same level of cardiovascular health.

The islanders have twice the level of urinary nitric oxide, a chemical associated with healthy flow of blood through the arteries. And those who drank cocoa with more flavanols had higher levels of nitric oxide.

Also, higher levels of epicatechin in the bloodstream were accompanied by improved blood flow. Lab tests showed that flavanols allow vascular tissue to relax.”

More good, and unsurprising news, the New York Times reports on a recent Swedish study indicating that cardiac health improves in patients who eat chocolate regularly.

Here’s an excerpt:

“The scientists followed 1,169 nondiabetic men and women who had been hospitalized for a first heart attack. Each filled out a standardized health questionnaire that included a question about chocolate consumption over the past 12 months. Chocolate contains flavonoid antioxidants that are widely believed to have beneficial cardiovascular effects.

The patients had a health examination three months after their discharge from the hospital, and researchers followed them for the next eight years using Swedish national registries of hospitalizations and deaths. After controlling for age, sex, obesity, physical inactivity, smoking, education and other factors, they found that the more chocolate people consumed, the more likely they were to survive. The results are reported in the September issue of The Journal of Internal Medicine.”
