When Na-replete rats were given a choice between water and isotonic saline, they consumed more of the isotonic saline. Their ingestive responses to a choice between salted and unsalted food, however, were not studied in the same detail. Because humans consume salt in or on food rather than in pure water, this lack of information called into question the use of the rat as the animal model for human excess salt consumption. In experiment 1, 16 Sprague-Dawley rats were given 1-h access to salted and unsalted foods (potato chips, peanuts, soup) commonly consumed by humans in the salted form. In each choice situation, rats consumed more of the unsalted variety of solid food. In experiment 2, the concentration of salt in a wider variety of foods was varied. Rats (15) were allowed a choice of a given salt concentration or the unsalted food. In no case was the salted solid food eaten in excess of the unsalted solid food and, in general, more of the unsalted solid food was eaten. In a 3rd experiment, 2 groups of 8 rats were given exposure from weaning to either salted or unsalted potato chips. Three-mo. of exposure to salted chips or unsalted chips did not alter the rats'' relative intake of salted chips. When given a choice, more unsalted chips were consumed by both groups. Na-replete Sprague-Dawley rats generally prefer unsalted solid foods to salted ones.
