Public Health Perspectives on Sustainable Diets

Public Health Perspectives on Sustainable Diets, offered by Johns Hopkins University through Coursera, is a beginner-level online course designed to explore how food choices and food production affect both human health and environmental sustainability. The course addresses the urgent need to improve the sustainability of food systems while examining the complex relationship between diet and climate change. Drawing from the Johns Hopkins Center for a Livable Future and its graduate-level food systems curriculum at the Bloomberg School of Public Health, it provides a practical introduction to sustainable diets and their relevance across different global contexts.

Core Content

The curriculum is structured across three modules and examines food system sustainability, public health, diet, and climate change. It explores what defines a sustainable diet, why sustainable diets matter, and what dietary shifts may be needed in high-, middle-, and low-income countries to meet both sustainability and food security goals. The course also looks at climate impacts of foods and diets, water use, food waste, resilience, and evidence-based strategies for promoting more sustainable eating patterns.

Key Skills

Participants will develop the ability to understand food system sustainability and resilience, interpret the concept of sustainable diets, and assess how dietary patterns affect climate change, water use, and public health. The course helps learners strengthen their understanding of sustainable development, climate change mitigation, nutrition and diet, water sustainability, and systems thinking. It also supports a clearer understanding of evidence-based strategies that can advance sustainable diets across different settings.

Target Learners

This course is designed for students, early-career professionals, and learners interested in public health, nutrition, sustainability, and food systems. It is particularly relevant for those who want a beginner-friendly introduction to how diet choices intersect with climate change, food security, and health outcomes. Because Coursera lists it as beginner level with no prior experience required, it is suitable for a broad audience seeking foundational knowledge in sustainable diets and food system change.

Learning Format

Hosted on Coursera, the course is delivered in a flexible online format with three modules and an estimated completion time of seven hours. The learning experience includes videos, readings, graded assignments, and discussion prompts, allowing learners to engage with both core concepts and applied reflections at their own pace. Coursera also notes that the course offers a shareable certificate, includes four assignments, and is available in English with multiple language options.

Additional Benefits

The course offers practical value for learners who want to understand sustainable diets through both a public health and environmental lens. Its grounding in Johns Hopkins’ food systems curriculum adds academic credibility, while its focus on global dietary shifts, food security, and evidence-based strategies makes the learning directly relevant to current sustainability challenges. The shareable certificate also adds professional value for those seeking to demonstrate foundational knowledge in sustainable food systems and public health.
