In 1996, researchers discovered that chocolate contains anandamide, as well as two substances that could mimic anandamide's effects, N-oleoylethanolamine and N-linoleoylethanolamine (yes, those are both actual words). That's right, chocolate, the delectable treat that's allowed people to eat their feelings since 1900 BC. According to researcher Daniele Piomelli of the Neurosciences Institute in San Diego, the old wives' tale that chocolate is an aphrodisiac may have stemmed from the blissful effects it can deliver thanks to anandamide.
However, don't rampage through the Hershey's factory like Augustus Gloop and expect to feel as blitzed as you would from an evening of Bruce Banner consumption. Said Piomelli, "We are talking about something much, much, much, much milder than a high."
