This paper reviews the current evidence about behavioural insights in the field of (un)healthy food choice that can support the development of behavioural public-policy tools. It extends previous work on behaviourally based policies in health and food choice, both academic and professional. The core of the paper is a summary of reviews of behavioural insights-based interventions and the scientific evidence regarding their efficacy in nudging people towards healthier food choices. Overall, we cover 39 systematic literature reviews and meta-analyses published between 2010 and 2017. Additionally, we outline potential drivers and theories that could help to explain the mechanisms behind these interventions. The paper concludes with a discussion of the results and suggestions for policy-makers aiming to make use of behavioural insights in health policy.
