Dark chocolate as a remedy for emotional stress receives new support from a clinical trial published online in ACS’ Journal of Proteome Research: Gut Microbiota, and Stress-Related Metabolism in Free-Living Subjects. Men and women who ate just over an ounce and a quarter of dark chocolate a day for two weeks showed reduced levels of stress hormones in their bodies. Dark chocolate consumption also partially corrected other stress-related biochemical imbalances.
