Dark secrets of (dark) cocoa
Dark cocoa polyphenols improves mood and promotes calmness
by Newsletter Editor
Prior studies have found health benefits from cocoa antioxidant polyphenols. In this study, doctors gave 72 healthy adults a dark chocolate drink containing 500 mg or 250 mg of cocoa polyphenols per day, or a placebo. After 30 days, compared to placebo, those who had taken the high dose of cocoa polyphenols reported having a much greater sense of calmness and overall contentedness. While the polyphenols didn't appear to change mood within a couple of hours of drinking cocoa, the general overall mood benefits appeared over time, with participants reporting dark cocoa mood improvements at 30 days.
