Serving bowl selection biases the amount of food served

Abstract

Objective: To determine how common serving bowls containing food for multiple persons influence serving behavior and consumption and whether they do so independently of satiation and food evaluation. Methods: In this between-subjects experiment, 68 participants were randomly assigned to either a group serving pasta from a large-sized bowl (6.9-L capacity) or a medium-sized bowl (3.8-L capacity). Results: Analysis of covariance showed that when given a large-sized bowl, diners served 77% more pasta (364.0 vs 205.5 g; P.32). Conclusions and Implications: In contrast to those in studies involving larger-sized plates and spoons, people serving from larger bowls felt more satiated. These findings again highlight the role that external cues play in food consumption and show the importance of considering serving bowl size in nutrition education. © 2012 Society for Nutrition Education and Behavior.
