It covers all the aspects of food and addiction that are really crucial to our understanding and ability to move forward in the field. Needs some basic understanding of neurobiology and the relevant reward systems otherwise it's just jargon, but if you have that it's a really helpful aide.
I found each chapter covered something new and interesting about an area or aspect of the brain that many people are curious about. Written in an easy yet scientific style, it was a great way to get me used to the language of the brain. I would recommend to anyone even slightly interested in the brain/neuroscience, as it is the best introductory book I've read.
