Sustainable Diets Working Group: Case study report

Diet Dimensions’: a case study on a sustainable diets policy game


Current food systems face multiple challenges relating to access and affordability of nutritious diets and environmental impacts. At the same time, the world’s population is estimated to approach 10 billion by 2050. Consequently, food systems face massive, multi-dimensional challenges that require systematic and coordinated, global efforts. Sustainable Diets research presents an opportunity to explore these challenges by bringing together multiple sectors, disciplines and expertise to guide the development of local, national, regional and global policies. 

About this case study report

This report introduces the live social game ‘Diet Dimensions’. It is a novel method of engaging researchers, policymakers and key stakeholders to generate and inform policies for healthier and more sustainable food systems. 

Defining sustainable diets:

“Sustainable diets are those diets with low environmental impacts, which contribute to food and nutrition security and to healthy life for present and future generations. Sustainable diets are protective and respectful of biodiversity and ecosystems, culturally acceptable, accessible, economically fair and affordable; nutritionally adequate, safe and healthy; while optimising natural and human resources.”
FAO, 2012

Get involved – how to play the game

The game ‘Diet Dimensions’ is a work in-progress, informed and modified between each play session. The materials needed to set up a session are available on our website and free to use. We welcome any comments and suggestions and are happy for the game to be used to further research and policy around sustainable food systems.

ANH Academy Sustainable Diets Working Group

Assessing and improving the sustainability of food systems is a complex challenge. There are no universally-agreed criteria of measuring it, and policy makers face difficult trade-offs, e.g. promoting healthy diets at the expense of the domestic food processing industry. 
The Sustainable Diets Working Group aims to generate innovative methods and metrics for use in sustainable diets research and policy development through interdisciplinary research.
