Renewal of olfacto-gustatory pleasure by introducing new foods or through seasoning of previously consumed food might increase intake. OBJECTIVES: To explore whether sensory-specific satiety (SSS) for a food could be modulated, either by introducing a novel food or by a modification of sensory stimulation via seasoning the food just eaten.
