Cocoa extract may lower risk of heart disease, new study suggests
A new study finds that supplementing people's diets with cocoa extract, which is also found in dark chocolate, is linked with a lower risk of dying from heart disease.
The study published in The American Journal of Clinical Nutrition.
In the study, researchers examined more than 20,000 U.S. adults ages 60 and up, following up after several years, supplementing some participants' diets with cocoa extract. Those who received the supplement were significantly less likely to die of cardiovascular disease.
"We found that cocoa flavanol supplementation may reduce clinical cardiovascular events, including a statistically significant 27% reduction in… cardiovascular disease (CVD) death," study author Howard D. Sesso, ScD, MPH, tells Eat This, Not That!.
Flavanols are compounds found in cocoa powder, chocolate, and other foods, and they have been linked with a range of health benefits. A 2014 study on cocoa flavanols, also published in The American Journal of Clinical Nutrition, found that they could play a role in protecting you from cognitive decline as you age.
Additionally, a 2005 study published in the American Heart Association's Hypertension journal found evidence that flavanols from chocolate can reduce blood pressure.
One major point to flag in this most recent study is that researchers received grants from Mars, Incorporated, the company that owns M&M'S, Snickers, Twix, Dove and more. Mars provided the study pills and packaging. However, the implications of the study extend beyond just chocolate products.
"Flavanols are not only found in the cocoa bean, but also in berries, tea, and grapes, among other fruits and vegetables that remain a critical part of a healthy diet for overall health," Sesso says. "[This] was not a chocolate trial, but rather a trial testing a cocoa extract supplement."
He added that understanding exactly how cocoa flavanols affect cardiovascular health "requires additional research." Still, given the proven health benefits of dark chocolate, you may as well pick up a bar on your next trip to the grocery store, especially if you enjoy the taste.
