Nutrition and dietetic sciences can no longer ignore the rising environmental crisis from food production and consumption. Dietitians and nutritionists can and must help address the mismatch between global dietary trends, population health and planetary ecosystems.

Change is slow

The evidence for change is now very powerful, but change is slow. Dietetics and Nutrition have positive roles to help shift consumption towards a sustainable state.

EAT-Lancet Commission

The 2019 EAT-Lancet Commission (Willett et al, Food in the Anthropocene, The Lancet, January 2019) modelled the case for change on a planetary basis. The EAT-Lancet Commission on Food, Planet, Health brought together 37 world-leading scientists from across the globe to answer this question:
Can we feed a future population of 10 billion people a healthy diet within planetary boundaries? Dietitians can help translate the need for ‘planetary diets’ for different places.

New policy goals

New policy goals are needed if Europe is to achieve the goal of sustainable diets from sustainable food systems. Change is needed at multiple levels: domestic everyday life, towns and regions, nations and globally. What the problem is, and what needs to happen, varies by area, because eating patterns, wealth and geography vary within and between nations, and across Europe. This paper considers change at Europe, national and local levels. It suggests that there must be a cultural transition as well as an economic and supply transition.


Nutrition and dietetics can help bridge the social and biological sciences. People need help to translate the complex messages from science.
