#2- Dark Chocolate Contains the obromine
Dark chocolate contains theobromine, which harden tooth enamel. That means that dark chocolate, unlike most other sweets, lowers your risk of getting cavities if you practice proper dental hygiene but excess of anything is bad. So eating chocolate at a proper level is good. Theobromine is also a mild stimulant, though not as strong as caffeine. It can, however, help to suppress cough.
