Chocolate does more than make our bellies happy. It also makes our brains happy! That’s right, dark chocolate has the ability to increase serotonin in the brain due to its chemical make-up of tryptophan (amino acid that helps make serotonin), phenylethylalanine (natural anti-depressant), and theobromine (mood relaxer and stress reliever). The increase is serotonin leads to a good mood and reduction of stress. Thanks to dark chocolate’s mood enhancing properties, chocolate can even reportedly reduce symptoms of depression. In one study of over 13,000 adults, individuals who reported eating dark chocolate within 2 days had 70% less likelihood of reporting symptoms of depression compared to those who didn’t eat any chocolate.
