Sensory perception and health: Methodological considerations

Sensory perception significantly influences human health and behaviour, playing a pivotal role in food choices, dietary habits and overall well-being. This chapter explores the intricate relationship between sensory functions – namely taste, smell and oral tactile perception – and health. It examines the causes of sensory impairments and their impact on individuals' health and dietary behaviours. The discussion extends to methodological considerations, providing an overview of tools for measuring sensory perception, including self-reports and more objective methods such as the psychophysical tests available for each sensory modality. The chapter also highlights practical implications for selecting appropriate sensory evaluation methods based on clinical or research requirements and the capabilities and constraints of available tests. Moreover, it emphasises the importance of standardized protocols to ensure reliable, reproducible results in sensory studies. By addressing the multi-faceted roles of sensory perception in health and disease, the chapter underscores its relevance in sensory perception research, dietary practices and public health strategies.
