Increasing healthy food choices through nudges: A systematic review

Food marketing strategies constantly use trendy messages, novel displays, colourful floor decals, compelling store arrangements and other environmental triggers to exploit consumers; nudges hold the promise to adopt the same interventions to increase healthier choices. The purpose of this systematic review is to frame the state of the art and research gaps on nudging interventions aimed at increasing healthy food choice. Thirty-six articles reporting reviews or empirical studies performed between 2016 and 2018 were analysed. Over 80% of the reviewed empirical research reported positive outcomes. The work provides insights to further analyse the most promising approaches and critically discusses the core shortcomings of available studies. Finally, future research avenues are highlighted as the need for more replications and scalability of interventions
