Chapter synopsis:

This chapter focuses on using duality models to understand how consumers process information about food and nutrition. The chapter begins by discussing the elaboration likelihood model, arguably the most prominent dual-mode model in nutrition research. This is then followed by a discussion of the contribution of dual-system models as well as duality models’ potential to further our understanding of nutrition information processing, focusing on nutrition message and labelling effectiveness. It also describes contingency effects in nutrition information processing as well. A section on how duality models can guide future nutrition research is also provided.
