For business school teaching this documentary is a rich case for operations, marketing, strategy and public policy. It allows students to examine large scale process management, brand management in a mature market, and the tensions between health regulation, reformulation costs and consumer expectations. It also opens discussion of corporate responsibility in responding to obesity concerns and how multinational food firms balance profit, product reformulation and reputation.
