This self-paced, interactive module prepares public health professionals working in state and local health departments to develop or support food policy changes in their communities to encourage healthy food systems. The session begins with a discussion of why the public sector should be involved in developing policies around food and how local health agencies can lead the charge. Next, learners will learn about food system goals that can promote health and how to achieve those goals. Finally, learners will explore case studies that demonstrate how public health agencies have planned and implemented changes to their food systems.
