On the face of it, basic tactile sensation might seem the only essential sensory requirement for the delivery of foods and beverages to the digestive system. In practice, however, the appropriate delivery of raw materials for the maintenance and repair of the body requires complex sensory and cognitive processes, such that flavour sensation arguably constitutes the pre-eminent example of an integrated multicomponent perceptual experience. To raise the profile of the chemical senses amongst researchers in other perceptual domains, I review here the contribution of various sense modalities to the flavour of foods and beverages. Further, in the light of these multisensory inputs, the physiological and psychophysical research summarised in this paper invites optimism that novel ways will be found to intervene when nutritional status is compromised either by specific dietary restraints, or by taste and smell disorders.
