Regular readers know we love chocolate (and its molecules) for many reasons. What surprised us in the uncertainty of the psychological effects:
Our findings raise questions about the psychoactivity of theobromine in the psychological effects of chocolate. One possibility is that the combined effects of caffeine and theobromine, typically found in chocolate, have interactive effects….Another possibility is that most consumers of chocolate use more caffeine than the subjects we tested, and that the effects of theobromine may be especially evident in regular caffeine users. Little is known about sometimes reported “chocolate cravings”. It is possible that these have a neurobiological basis or, they may be related to appetites for hedonically pleasurable tastes, or other psychological states.
