This pocket guide is simply a tool to better understand what is contained in the foods we eat everyday. Many additives and ingredients are controversial, from a safety perspective. The intention of the guide is to provide a brief description of the additives and ingredients, and to provide additional reference material for anyone interested in learning more about the more controversial additives. The pocket guide does not recommend eating or not eating certain foods. Each individual should use their own judgement in determining what they want to eat.
