9. What is a healthy sustainable eating pattern?
This chapter looks at whether it is possible to identify dietary patterns that are good both for health and for sustainability. It begins by describing existing and emerging approaches to defining and measuring sustainable and healthy eating patterns (SHEPs), discussing some of the factors that make it difficult to do. It goes on to look at specific diets that may minimise negative environmental impacts and to explore whether recommended healthy diets are necessarily more environmentally friendly and vice versa. Next it explores the potential synergies and trade-offs that exist between healthy and low environmental impact diets. It ends by highlighting some of the questions that need to be addressed if we are to gain greater understanding of what SHEPs look like in different developmental contexts.
