Mapping Sustainable Diets: A Comparison of Sustainability References in Dietary Guidelines of Swiss Food Governance Actors

With the growing recognition of the food system for a transformation toward sustainability, there is a need for future guidance on food consumption and policy. In particular, dietary guidelines (DGs) have received increasing attention as potential tools for enabling transformative change. This paper analyzes how and to what extent different state and non-state actors in Switzerland incorporate sustainability aspects in their dietary guidelines. It examines how these DGs account for different dimensions at the basis of sustainability thinking, including the classic environmental, economic, and social dimensions as well as issues of health and governance. Our analysis shows the explicit inclusion of sustainability aspects in all DGs of the chosen actors in Switzerland, addressing at least one sustainability category predominantly. Through the analysis of the different stakeholders, different areas of focus become apparent, with each stakeholder covering specific niches of sustainability. On this basis, the transformative role of non-state actors in developing the concept of sustainable diets is discussed.
