Sensory-specific satiety
1986
Rolls, B.J.
A literature review focuses on the way in which hedonic factors can influence food selection, stressing that no single factor may necessarily, by itself, affect such selection. Topics include: sensory changes ("alliesthesia"); the effect of physiological need on food selection; sensory-specific satiety and its mechanisms; nutrient-specific satiety; flavor variety and food intake; the effect of monotony in food selection on satiety; and interactions among food variety, food monotony, and body weight. It is concluded that the pleasantness of a food's taste, appearance, smell, and texture decreases during its consumption, while the perceived pleasantness of other foods not consumed remains essentially unchanged. When a variety of foods is available, there will be a tendency to switch from 1 food to another due to the hedonic sensory-specific satiety syndrome present in humans.(wz)
