Can you become addicted to chocolate?



The term “chocoholic,” usually said with a smile, actually nods to a potentially serious question: can a person become addicted to food? There are three essential components of addiction: intense craving, loss of control over the object of that craving, and continued use or engagement despite bad consequences. People can exhibit all three of these in their relationships with food. It’s most common with foods that deliver a lot of sugar and fat — like chocolate — because they trigger reward pathways in the brain. In some animal studies, restricting these foods induced a stress-like response consistent with the “withdrawal” response seen in addiction. Much of the scientific discussion about food addiction has been sparked by the epidemic of obesity sweeping the U.S. and many other countries. Many people who are overweight crave food, lose control over eating, and experience negative health effects that should, but don’t, serve as a deterrent. The influence of stress on eating provides another link between food and addictive behavior.
