Satiety can be relatively specific to particular foods, and this is an important factor in influencing human food selection and the amount of food eaten. As a food is eaten, its taste and appearance decrease in pleasantness, but the taste and appearance of other foods remain relatively unchanged. The changes in pleasantness are highly correlated with the amounts of foods that will be eaten subsequently in a meal. Therefore more is eaten during a meal consisting of a variety of foods than during a meal with just one of the foods, even if that food is the favorite. This enhancement depends at least in part on the sensory properties of foods in that change in just the flavor or shape of foods affect intake. Although changes in the color of foods do not affect intake, the taste of colors that have been eaten becomes less pleasant and this probably affects food selection. The more dissimilar foods are, the greater the enhancement of intake by variety in a meal will be. As well as affecting food intake, the change in the pleasantness of foods which occurs while eating is an important determinant of food selection in that it promotes consumption of a varied diet.
饱腹感可能相对特定于某些食物，这是影响人类食物选择和进食量的一个重要因素。当食用一种食物时，其味道和外观的愉悦感会降低，但其他食物的味道和外观相对保持不变。愉悦感的变化与随后一餐中会食用的食物量高度相关。因此，与只吃一种食物的一餐相比，吃由多种食物组成的一餐时会摄入更多食物，即使那种食物是最喜欢的。这种摄入量的增加至少部分取决于食物的感官特性，因为仅仅食物味道或形状的变化就会影响摄入量。虽然食物颜色的变化不会影响摄入量，但已食用颜色的味道会变得不那么愉悦，这可能会影响食物选择。食物之间差异越大，一餐中因种类多样而导致的摄入量增加就越大。除了影响食物摄入量外，进食时食物愉悦感的变化是食物选择的一个重要决定因素，因为它促进了多样化饮食的消费。
