Romantic Jealousy, Cortisol, and Dark Chocolate

Romantic jealousy can turn love into hate and tenderness into aggression or even homicide. However, despite its enormous impact, research on romantic jealousy is still in its infancy. In this article, a romantic jealousy-cortisol-dark chocolate hypothesis is presented. Cortisol elevation is hypothesized to play a key role in the neurobiological mechanism of romantic jealousy. Moreover, dark chocolate, rich in flavonoids, is hypothesized to be a potential treatment for romantic jealousy because of its cortisol-lowering effect. To test this hypothesis, a study protocol is provided in this article for future research.
