“…Such alterations also do not appear after a long term block of the olfactory sensi tivity, chronic anosmia (carp) (Kasumyan and Sidorov, 2005b;. Similar results have also been obtained for humans when com paring congenital anosmia patients and healthy per sons (Gilland, 1921;Crosland et al, 1926;Doty, 1977;Ferris et al, 1985). However, taste preferences alter in the Slc:ICR mice with acute anosmia despite the absence of any changes in the electrophysiological response recorded in the gustatory nerve (chorda tym pani) (Uebayashi et al, 2001).…”

We compared taste preferences, taste sensitivity, and behavior in testing food objects in the group of intact and two groups of sensory deprived rainbow trout Oncorhynchus mykiss yearlings. We demonstrated that long term anosmia (for 9 months), as well as anosmia (for 9 months) combined with enucleation (object vision deprivation for 4 months), does not change the taste preference of fish for the agar pellets containing amino acids (L alanine, L proline, L histidine, or glycine; 0.1 M). For all groups of fish, the threshold L alanine concentration in pellets that caused a significant increase in consumption is 0.01 M. We showed that sensory deprived fish change their behavior of gustatory testing, namely, the rate of repeated snaps decreases as well as the pellet retention time in the mouth cavity. These results demonstrate that long term anosmia combined with a partial vision deprivation does not significantly change the taste preferences and sensitivity in the fish that have no external taste buds. However, the observed reduction in the testing time of food objects and other changes in fish feeding behavior may suggest some functional alterations in the intraoral sensory systems (gustatory and/or tactile).

“…He reported that he was not able to demonstrate any such compensatory changes due to loss of the sense of smell. Crosland et al (Crosland et al, 1926), using themselves as controls, tested a single anosmic person's ability to taste food. They stated that under blindfold conditions the anosmic person's ability to detect food placed into his mouth did not differ from, or may even have been superior to, that of a person with a sense of smell in the normal range.…”

The inability to detect odours, anosmia, can cause profound psychological effects resulting in feelings of physical and social vulnerability and victimization. In addition, there may be unhappiness related to the loss of the ability to detect pleasurable food smells and, as a consequence, anosmics may develop problems relating to eating. These profound effects arise from a condition which can have a rapid onset and a very poor prognosis for recovery, and are largely treated with a lack of sympathy and indifference by people with normal olfactory ability. In an attempt to educate, inform and help sufferers, a questionnaire was developed in the early 1980s and sent to those who contacted the Warwick Olfaction Research Group. The responses from this questionnaire form the basis of this review. Feelings of personal isolation, lack of interest in eating and emotional blunting were common responses from these sufferers and it seems that we still have some way to go before an adequate recognition of problems associated with anosmia is gained by the general population and, more importantly, within the medical profession.

“…All participants were instructed to repeatedly consume and evaluate the pleasantness of flavor and mouthfeel of different food items. We further hypothesized that any exaggerated SSS among the hyposmic/anosmic participants would be limited to the pleasantness ratings of flavor as olfactory deficit affects flavor perception but not somatosensory perception of food texture (see e.g., Crosland et al 1926Crosland et al , 1928.…”

Eating Without a Nose: Olfactory Dysfunction and Sensory-Specific Satiety

2010

Odor stimuli play an important role in the perception of food flavor. Olfactory dysfunction is thus likely to affect eating behavior. In the present study, we hypothesized that dysfunctional olfactory perception promotes sensory-specific satiety, a decrease in pleasure derived from a certain test food during and shortly after its consumption relative to other unconsumed control foods. 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. We found evidence for sensory-specific satiety (SSS) regardless of olfactory function. It thus appears that olfactory deficits have no major effect on SSS.
