Stress People Eat More Chocolate

A new cross-sectional study suggests individuals with depressive symptoms eat more chocolate, but it does not explain why.

The study, published in the April 26 issue of the Archives of Internal Medicine, included 931 adults not using antidepressants. The mean age of study subjects was 57.6 years and mean body mass index was 27.8 kg/m2 or less; 70.1% were male, 80.4% were white, and 58.8% were college educated. Subjects provided information on chocolate consumption (frequency and amount) and completed the Center for Epidemiological Studies-Depression (CES-D) scale.

Subjects who screened positive for depression, defined as a CES-D score of 16 or higher, reported consuming significantly more chocolate than those not screening positive for depression (8.4 vs 5.4 servings per month; P = .004).

Those with CES-D scores of 22 or greater, indicating probable major depression, consumed 11.8 servings of chocolate per month (P value for trend < .01). These associations were evident for men and women.

According to the researchers, several nutrient factors that could be linked to mood, such as increased caffeine, fat, carbohydrate, or energy intake, bore no significant correlation with mood symptoms, suggesting relative specificity of the chocolate finding.
