Abstract

This study assessed the influence of introducing a new food after repeated presentations of one food on food consumption, hedonics, and salivation. Male subjects were provided repeated 150-calorie courses of pizza or cheeseburger until satiety. Hedonics and salivation were measured before each course. Subject were then provided an additional 450 calorie course of the same or the new food. During the development of satiety, subjects showed reliable increases in fullness and decreases in hunger and hedonics. Salivation briefly increased to maximal salivation, followed by reliable decreases. No differences in pattern of change for fullness, hunger, hedonics or salivation were noted across foods. Presentation of the new food resulted in significantly greater caloric consumption than another serving of the same food (130 vs. 44.5 kcal), an increase in hedonics and salivation relative to presentation of the same food, with no influence on hunger or fullness. These results suggest that after satiety develops, response recovery for subjective, physiological, and behavioral components of eating can be observed when new, palatable foods are presented.
