Is Sugar Like a Drug to the Brain?

There was a study from last year that showed that sugar can have effects on the brain similar to cocaine (http://www.ncbi.nlm.nih.gov/pubmed/23719144). We get our diet our order, we exercise, but we may still find ourselves craving that chocolate bar or package of cookies. What is it about sugar that is so addictive? How are we affected when we eat too much sugar? Sara Gottfried and Pedram Shojai discuss the addictive power of sugar and stage an intervention.
