An experiment to evaluate the effectiveness of the taste aversion conditioning paradigm in the generalization of aversion with palatable foods was performed. Ten experimentally naive females Wistar rats and three types of foods were used: a) standard purina rodent chow, b) vanilla flavor cookies and c) chocolate-flavored cookies. Subjects were divided into two groups, five subjects per group. Using the taste aversion conditioning paradigm protocol, subjects were exposed to the types of food keeping an intake record. The experiment demonstrated that rats can acquire an aversion to palatable foods accompanied by a tendency to generalize, when using elements that share characteristics such as nutritional content and texture. In addition, the intake of a food that does not share the characteristics of texture, taste, smell and energy content with the one used for conditioning was not been affected. These findings indicate that the aversion generalization seems to depend on the properties of the food used.

Palabras llave : feeding behavior; food aversion learning; palatable foods.
