Dynamics of demand-side and supply-side responses to front-of-pack nutrition labels: a narrative review

The European Union (EU) food market is characterised by the presence of several front-of-pack nutrition labels (FOPLs), some of which have only been introduced lately. While the EU Commission proposed to harmonise and possibly mandate the use of FOPLs, agreement on which label to adopt has not been reached. This review explores the main issues related to the adoption of FOPLs from both the demand-side and the supply-side perspective with the aim of providing an updated evidence-based road map for the development of future studies that can contribute to extend scientific evidence and guide future food policies.
