We tend to like things that are sweet and melt in the mouth. But chemical composition may play a role in the chocolate cravings. More women than men report cravings for chocolate, and often women crave chocolate the most before menstruation, when hormone levels are highest. Another study, conducted in Italy, tested the theory that cocoa contains some of the same chemicals found in marijuana, which could have something to do with why chocolate seems to bring such a feeling of pleasure to some people. The researchers found that while chocolate does contain some of these chemicals, it's probably not in high enough quantities to really have an effect.
More study needs to be done.
If you crave chocolate, you can rest assured that it's not entirely bad for you. In fact, doctors at UT Southwestern Medical Center at Dallas say chocolate can fit into a healthy diet.
