Formal approaches are those taken by government bodies through laws, court decisions and actions of government regulatory bodies. Informal approaches are those taken by individuals, non profit organizations, industries working at self-regulation, etc. Because the formal means are tied to a particular legal system, this kind of approach is nation-specific and the book focuses on the United States. But many of the things the authors have to say about US food policy and the interactions between formal and informal approaches would also be of interest to policymakers and food industry professionals in other countries. Coverage includes the regulation of food advertising on children's television and the internet, regulation of school lunch programs and the influence of Eleanor Roosevelt and Michelle Obama.
