Both food processors and consumers have a basic need for valid and relevant nutritional information; on the one hand to guide production and marketing of genuinely functional products, and on the other to allow selection of products according to efficacy. Data on product efficacy that are relevant, in the sense of being easily communicated, understood and appropriately applied are, however, often unavailable. There is little to guide evidence-based food choice to meet such widespread health challenges as control of blood glucose levels, and maintenance of large bowel function, two examples that will be considered in detail in this chapter.

New approaches to nutritional information must, therefore, focus not only on data that validly represent physiological changes linked to health, but also on transforming the data to show meaningfully the relative efficacy with which products can bring about change. This chapter focuses on new approaches to nutritional information that attempt to link food choice to health end-points through effective communication.
