Most women, when they have problems with their careers or love life, turn to chocolates to bring some pick-me-up. Studies say that the serotonin in the chocolate makes it a mood-enhancer. But a new research has just found out that there’s a link between chocolates and depression.

The research, which was made by Dr. Natalie Rose of UC San Diego and UC Davis, was published in the Archives of Internal Medicine. It said that out of the 1,018 people who took part in the study, those who were judged to have possible depression and consumed an average of 11.8 ounces of chocolate per month also scored highly in the depression scale.

According to the scientists, the findings of the study (the high depression scale) cannot be explained in general by increase in fat, carbohydrate and energy intake.

Still, there’s no evidence that points out chocolates cause depression. Scientists said that, “Higher CES-D depression scores were associated with greater chocolate consumption. Whether there is a causal connection, and if so in which direction, is a matter for future prospective study.”

There are two hypotheses you can derive from this study—either chocolate cause a temporary mood lift then followed by a longer-term drop or it is simple that people who are down are more likely to eat a bar of chocolate.
