title: Influence of experience on response to bitter taste.
abstract: Sucrose octaacetate, which tastes bitter to humans, can reduce the energy intake of rats when added to their diet. The reduction in energy intake is transient, lasting no more than 5 weeks. Rats that no longer reduce intake in response to sucrose octaacetate still avoid food containing it in choice tests, although to a lesser degree than rats having no previous experience with sucrose octaacetate. The ability of sucrose octaacetate to reduce preference without reducing long-term intake accounts for the previous finding that a wet diet containing sucrose octaacetate can stimulate hyperphagia yet be less preferred than the control diet. Sucrose octaacetate was more effective in reducing intake of a wet than of a dry diet. This last observation indicates that adding water to a food makes it easier for an animal to taste its food.
