Introduction

Olfaction is a highly emotionally charged sense and contributes to our quality of life, which olfactory impairment or dysosmia thus strongly impacts. The aim of the present study was to examine how olfactory deficits alter eating behavior, which is a pillar of health and well-being.

Methods

Patients with quantitative smell impairment and control participants were asked to perform a series of chemosensory tasks: odor identification and ratings of odor intensity, pleasantness, familiarity, irritation, and edibility. They also filled out a detailed food questionnaire.

Results

Results showed significant decrease in olfactory function in smell-impaired patients. Although no significant consequences of dysosmia were found for most aspects of food preferences and culinary habits, the patients were less attracted than controls by novel foods and tended to experience less pleasure when eating. They also used significantly more condiments such as sugar, mayonnaise, or sour cream to make their dishes tasty.

Conclusions

Olfactory impairment has a clear effect on certain aspects of eating behavior.

Implications

These findings highlight the compensatory mechanisms that go along with dysosmia. This also reflects the patients’ attempts to restore part of the lost flavor and its hedonic component through non-olfactory cues.

睡眠障碍引起的与睡眠障碍有关的变化

介绍

嗅觉是一种充满情感的感觉，并有助于我们的生活质量，因此嗅觉障碍或功能障碍会严重影响我们的生活。本研究的目的是研究嗅觉缺陷如何改变饮食行为，这是健康和福祉的支柱。

方法

要求具有定量气味障碍的患者和对照组参与者执行一系列化学感应任务：气味识别以及气味强度，愉悦性，熟悉度，刺激性和可食性的等级。他们还填写了一份详细的食物问卷。

结果

结果表明，嗅觉受损患者的嗅觉功能显着下降。尽管在饮食偏爱和烹饪习惯的大多数方面都没有发现睡眠障碍的显着后果，但是与对照组相比，患者对新颖食物的吸引力更小，进食时的愉悦感也更少。他们还使用了更多的调味料，例如糖，蛋黄酱或酸奶油，使菜肴更美味。

结论

嗅觉障碍对饮食行为的某些方面具有明显的影响。

含义

这些发现强调了与记忆障碍有关的代偿机制。这也反映了患者试图通过非嗅觉提示来恢复失去的部分风味和享乐成分。
