A study published in this week's Archives of Internal Medicine evaluated 931 men and women, none of whom were taking antidepressant medication. Those who screened positive for criteria of depression had a higher rate of self-reported monthly chocolate consumption, with the rate of cocoa nibbling going up as depression became more serious.
Among those whose depression ranked as more severe, an average of 11.8 servings of chocolate were consumed each month. The study quantified one serving as 1 ounce, about two thirds of a regular Hershey bar. Further, women ate more chocolate than men, with the most depressed putting away 16 servings a month.
