Selection of nutritive and nonnutritive solutions under different conditions of need.

Abstract

CONSUMPTION OF NUTRITIVE (3%, 6.5%, OR 10% GLUCOSE) AND NONNUTRITIVE (.25% SACCHARIN) SOLUTIONS BY RATS WAS MEASURED DAILY DURING PROLONGED FOOD-SATIATED AND FOOD-DEPRIVED CONDITIONS. ANIMALS PREFERRED 6.5% AND 10% GLUCOSE SOLUTIONS TO SACCHARIN WHEN SATIATED AND WHEN HUNGRY; SS WHICH PREFERRED 3% GLUCOSE SOLUTION TO SACCHARIN WHEN SATIATED PREFERRED SACCHARIN WHEN HUNGRY. TASTE PREFERENCE MAY CHANGE DURING FOOD DEPRIVATION, BUT CHANGE IS NOT DEPENDENT UPON NUTRITIONAL VALUE. EVEN UNDER SATIATED CONDITIONS, SS MAY SHIFT THEIR PREFERENCE OVER TIME. FURTHERMORE, FOLLOWING A CHANGE IN PREFERENCE DURING FOOD DEPRIVATION, SS MAY NOT REVERT TO THEIR INITIAL PREFERENCES WHEN SATIATED. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
