This literature review, undertaken by the Food Climate Research Network and Chatham House (link is external), and in association with EAT who also kindly supported the work, considers what the evidence has to say about effective ways of shifting people’s consumption patterns in more sustainable and healthy directions.
Having summarised the current state of knowledge on what sustainable healthy eating patterns look like, it focuses on four key eating practices that potentially offer win-wins for health and sustainability (while acknowledging qualifiers and caveats). These are 1. Increased consumption of plant based foods including fruit and vegetables; 2. Reduced meat consumption; 3. Shifts in palm oil consumption (i.e. not always or necessarily reductions); and 4. Reductions in sugar intakes. It also considers, 5. a fifth area where health and environmental goals diverge – the case of fish.
The review clusters interventions into the following categories as set out in the following table (see page 19 of the report) and uses this typology to structure the health and environmental evidence base and the research findings.
