Chew On This: Everything You Don't Want To Know About Fast Food is a nonfiction book that will have students clamoring. Once one student shares a particularly gross passage about the food they crave, they will all want to read this book to have facts with which to pester their families.
Fast food has an even more mythical status on my island, where no such restaurants exist. If someone is eating KFC or Sbarro at school, that means someone went to Nassau or the States and brought them back these goodies. I find it helpful to counteract that worship with some reality. In my eighth grade class, we read the chapter on soda together. There is an image in the book of baby teeth which had rotted because the child was given soda in her bottle. Apparently, there was nothing shocking about these teeth to my students, who all knew at least one person with a similar mouth. This led to really fantastic discussions about responsibility and hygiene. I would love to see Chew On This incorporated into the Health curriculum at our school as required reading. For kids who adore fast food, it's a bit of a game changer.
