Food or Medicine?

Abstract

Functional foods offer consumers a range of products that contain modified ingredients to treat specific diseases. The value of this product category has grown considerably since its introduction over a decade ago. This paper reports on qualitative research conducted into the choice criteria used for functional foods. It then compares these to the categories outlined in Khan's food choice model (1981) in order to determine whether functional foods should be treated as a food choice purchase. The findings of this research show that functional food can be treated as a food purchase because most of the choice influences found can be categorised into Khan's conceptualisation. However, additions and redefinitions are suggested. A separate category for family influence was found, as was the requirement to redefine “nutrition” within the model to accommodate the curative benefits of functional foods.
