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.
气味刺激在食物味道感知中起着重要作用。因此，嗅觉功能障碍可能会影响进食行为。在本研究中，我们假设，嗅觉感知障碍会促进感官特定饱腹感，即在食用和刚食用完某一特定测试食物时，与其他未食用的对照食物相比，该食物所带来的愉悦感会下降。共有 34 名嗅觉减退/嗅觉丧失的参与者与 29 名嗅觉正常的对照组参与者进行了比较。所有参与者都反复食用相同固定份量的一种食物，这一过程已知会引起感官饱腹感。我们发现了感官特定饱腹感（SSS）的证据，而不论嗅觉功能如何。因此，嗅觉缺陷似乎对 SSS 没有重大影响。
