Jealous Much? Try Some Dark Chocolate

Jealousy can become psychologically distressing.

Jealousy appears to be linked to elevated cortisol levels in the human brain.

Flavonoids in dark chocolate reduce cortisol levels; this treat may also reduce jealousy. (More research is needed.)

However, because jealousy can turn into more serious feelings of depression, anxiety, feelings of violence, or self-harm, she cautions that people should carefully monitor and seek professional help if these feelings persist or worsen.
