Just say the word “Chocolate,” and you evoke a visceral reaction in people… Mouths water, pupils dilate and stomachs rumble. You rarely hear someone say, “No chocolate for me.” Or, “I’m gonna pass on that chocolate cake.” Ever hear, “I need some chocolate?” All the time. Why is this? Does chocolate have some mystical power over us? How do our chocolate cravings make us drive to the store at 3am, just so we can experience that smooth texture and sweet aftertaste? One thing is for sure, there is a chemical component present in chocolate that does not exist in other foods.
