On sensory satiation, olfactory dysfunction and the lost ability to enjoy foododour stimuli play an important role in the perception of food flavour and as such, an olfactory dysfunction is likely to affect eating behaviour. Indeed, many people suffering from olfactory loss report experiencing diminished joy in eating. In the present study we hypothesized that dysfunctional olfactory perception promotes sensory satiation, a decrease in pleasure derived from a certain test food during and shortly after its consumption relative to other unconsumed control foods. In the present study, a total of 34 hyposmic/anosmic participants were compared with 29 normosmic control participants. All participants repeatedly consumed a fixed portion of one and the same food item, a procedure known to induce sensory satiation. The results showed clear evidence for such satiation regardless of olfactory function. Therefore, we conclude that quantitative olfactory deficits such as hyposmia or anosmia do no affect sensory satiation and that the diminished joy in eating probably is not associated with any increased sensitivity to sensory satiation.
