Chocolate cravings may be a sign of a more serious health problem.
The scientists discovered that those who ate the most chocolate scored the highest on depression tests. People with higher scores ate about 12 servings of chocolate a month.
Depression could trigger the need to self-medicate, and for many people, chocolate is the drug of choice, according to researchers.
"Our study confirms long-held suspicions that eating chocolate is something that people do when they are feeling down," said study co-author Beatrice Golomb, an associate professor of internal medicine at the UCSD School of Medicine. “Because it was a cross sectional study, meaning a slice in time, it did not tell us whether the chocolate decreased or intensified the depression."
The study was published in the Archives of Internal Medicine.
