Unhealthy food is the leading cause of premature death and preventable illness around the world today. Predatory marketing makes a significant contribution to this burden. Public health professionals can play an important role in reducing the prevalence and exposure to predatory marketing. This two-part training module develops an understanding of the current landscape of predatory marketing of unhealthy food and beverages, and how it promotes negative health outcomes particularly for vulnerable populations. This program will define the role of health departments in addressing predatory marketing, outline ways health departments can help document predatory marketing in their communities, and provide recommendations and examples of policy engagement activities public health professionals can get involved in.
