Chocolate is an aphrodisiac?
There is no definitive evidence to say so. Chocolate contains three substances, caffeine, theobromine and phenyethylamine. Caffeine acts as a stimulant. Theobromine stimulates the heart muscle and the nervous system and phenyethylamine is reputed to be a mood elevator and an anti-depressant. The combination of these three substances gives you extra energy. But these ingredients are present in a small bar of chocolate in very small proportion, so moderation is the only key.
