People who regularly eat chocolate are more depressive, experts have found.
Research in Archives of Internal Medicine shows those who eat at least a bar every week are more glum than those who only eat chocolate now and again. Many believe chocolate has the power to lift mood, and the US team say this may be true, although scientific proof for this is lacking. But they say they cannot rule out that chocolate may be a cause rather than the cure for being depressed.
In the study, which included nearly 1,000 adults, the more chocolate the men and women consumed the lower their mood. Those who ate the most - more than six regular 28g size bars a month - scored the highest on depression, using a recognised scale. None of the men and women were on antidepressants or had been diagnosed as clinically depressed by a doctor.
Dr Natalie Rose and her colleagues from the University of California, San Diego, say there are many possible explanations for their findings, and that these need to be explored.
