This course will help guide policy makers, advocates, and program managers as they design, plan, and implement sodium reduction interventions to protect public health. We invite you to see what interventions have been proven at scale, what shows promise, and what lessons have been learned along the way from the implementation of sodium reduction strategies all around the globe. Our emphasis is implementation in settings with resource constraints. There are nine modules in this course. The first two modules set the stage with information on the science of sodium and context for lowering intake at a population level; the next five modules describe specific interventions; and the final two modules discuss comprehensive strategies in the wider context of public health, as well as tools for monitoring and evaluating interventions.

What's inside
Syllabus
Module 1: Overview of Global Sodium Reduction
In this first module we provide a course overview. We will explain the significant role that sodium plays in the development of high blood pressure and cardiovascular disease in people all over the world. Sodium intake needs to be lowered in every country to benefit the health and economic well-being of all populations. But how do we do it? What has worked before? We will discuss these topics throughout the course. First, let’s take a look at cardiovascular disease around the globe. Then we’ll look at what sodium does in the human body, what happens over time when we eat too much sodium for our bodies’ needs—and what can happen when we lower the amount of sodium we eat.

Reviews summary
Global sodium reduction strategies for policy makers
According to learners, this course provides a comprehensive and practical guide to global sodium reduction strategies. Students particularly value its focus on actionable interventions for policymakers and program managers, especially for resource-constrained settings. The content is praised for its clear, module-based structure, covering everything from the science of sodium to real-world implementation examples like Front-of-Pack Labels. While widely regarded as highly relevant for public health professionals, a few reviews noted a desire for more interactive elements or diverse global case studies beyond existing examples. Overall, it's considered an essential foundational course for those looking to impact population health.
Offers a well-organized and thorough overview of strategies.
"The nine modules provide a logical flow from the science of sodium to implementation and surveillance."
"I appreciated the breadth of topics covered, from low-sodium salt to public food procurement policies."
"This course delivers a foundational understanding of sodium reduction that's easy to follow and absorb."
Provides diverse real-world examples from around the world.
"The deep dive into Chile's FoPL implementation was a standout; I appreciated the lessons learned from their challenges."
"It's refreshing to see interventions discussed with a true global lens, not just Western examples."
"I value the practical examples from different countries, which helps me adapt strategies locally."
Equips professionals with actionable strategies for public health.
"This course directly applies to my work as a public health program manager; the focus on resource-constrained settings is invaluable."
"I found the practical strategies for food reformulation and Front-of-Pack Labels to be extremely helpful for policy development."
"The content truly helps in designing and implementing sodium reduction initiatives in my country."
Highly relevant for public health and nutrition professionals.
"As a public health professional, this course was exactly what I needed to enhance my understanding of global health initiatives."
"The policy-oriented approach is perfect for anyone working in public health advocacy or program management."
"I now feel better equipped to contribute to sodium reduction efforts in my community and beyond."
Some learners desired more interactive elements or discussions.
"I wished for more interactive exercises or opportunities for peer discussion within the modules."
"While the content is strong, I felt it was very lecture-based; more hands-on activities would be beneficial."
"I would have liked more practical case studies or simulations to apply the concepts directly."
