• A minority of consumers increasingly care but most diets still fall short of nutritional guidelines and many consumers do not always act in line with their beliefs.
• There are predictable socio-economic differences across broad consumption trends but the impact of wider socio-demographic factors is less clear.
• The food environment is changing but the full impact of this on consumption is unclear .
• The food environment, which is likely shaped by powerful food system actors, is a significant driver of consumption.
• Food decisions are not always consciously deliberated and are determined by culture, social environment and sense of identity, and what we eat is often a matter of habit and convenience.

What we eat has big implications for our health, our society and the environment. Unhealthy and nutritionally poor diets lead to ill health. The current food system and people's food practices have negative impacts on the environment, leading to greenhouse gas emissions, deforestation and biodiversity loss. Addressing these complex challenges requires changing how food is produced to ensure it is more sustainable, and, importantly, changing consumption to ensure it is healthier and more sustainable. Therefore, understanding food consumption trends, what drives them and how we can change consumption practices through interventions is crucial to inform policy.

The aim of this study commissioned by the Department for Environment, Food and Rural Affairs was to provide an overview of the existing evidence in four main areas: (1) the trends related to consumer food practices and attitudes, and to the changing food environment (e.g. out-of-home sector, online retail models) in the UK; (2) the drivers of consumption (e.g. the role of information or food system actors); (3) interventions that can influence food consumption practices; and (3) the differences between groups, or 'food publics', across the trends, drivers and interventions (i.e. segmentation). Researchers conducted a rapid evidence assessment, with a focus on identification of existing evidence and evidence gaps within high-quality, primarily academic literature from the last ten years. This report provides evidence around these questions and identifies areas of uncertainty where more evidence is required and, based on this, suggests a number of priority areas for further research and action by policymakers.
