食物的选择和摄取受到感官和代谢过程的指导。味觉和嗅觉在选择和摄取的感官效应中起着关键作用。本文从食欲、选择、摄取和饱足感四个方面对嗅觉和味觉在进食行为中的不同作用进行了全面的综述和论证。嗅觉在进食行为中主要起着启动作用。已经证明，暴露在(鼻腔)气味中会引起食欲，特别是对被暗示的食物。然而，气味对食物选择和摄取的影响还不太清楚，还可能取决于参与者对气味的意识或强度，或个性特征。另一方面，在消费过程中，味觉具有明显的(宏观)营养感知系统的作用。味道和质地一起决定进食率，从而决定食物在口腔中的口腔暴露时间，从而导致饱腹感。这些实验研究的结果应该考虑到现实生活中的情况，以评估对能量摄入量的长期影响。有了这些知识，就有可能引导人们的饮食行为以及食品产品的开发，走向一个肥胖程度较低的社会。
Food choice and food intake are guided by both sensory and metabolic processes. The senses of taste and smell play a key role in the sensory effects on choice and intake. This article provides a comprehensive overview of, and will argue for, the differential role of smell and taste for eating behavior by focusing on appetite, choice, intake, and satiation.The sense of smell mainly plays a priming role in eating behavior. It has been demonstrated that (orthonasal) odor exposure induces appetite specifically for the cued food. However, the influence of odors on food choice and intake is less clear, and may also depend on awareness or intensity of the odors, or personality traits of the participants. Taste on the other hand, has a clear role as a (macro) nutrient sensing system, during consumption. Together with texture, taste is responsible for eating rate, and thus in determining the oral exposure duration of food in the mouth, thereby contributing to satiation.Results from these experimental studies should be taken to real-life situations, to assess longer-term effects on energy intake. With this knowledge, it will be possible to steer people's eating behavior, as well as food product development, toward a less obesogenic society.
