Brief Summary
The purpose of this study is to test the effects of large food portions on children's eating. Experiment 1 will test the effect of portion size on children's consumption of sweetened beverages; we hypothesize that serving large beverage portions will increase the amount of energy children consume from this food. Experiment 2 will test the effects of portion size on children's intake of fruits and vegetables (FV) affect intake whether such effects are moderated by children's FV preferences and; we hypothesize that serving large fruit and vegetable portions will produce increases in children's intake of these foods, particularly for children who like fruit and vegetables. Experiment 3 will evaluate how food energy density affects children's response to large portions; we hypothesize that large portions will have the greatest influence on children's energy consumption when foods are energy dense. Experiment 4 will begin to address perceptual mechanisms by which large portions affect children's eating.

Outcome Measures
Primary Outcomes (2)
Intake of portion manipulated foods
In each experimental condition; 4 times in each 2 x 2 factorial experiment
Total energy consumed
In each experimental condition; 4 times in each 2 x 2 factorial experiment
Study Arms (1)
Portion Size
EXPERIMENTALEach experiment manipulated food portion size of beverages, entrees, and side dishes
Interventions
Each of four experiments involves a 2 x 2 within-subjects factorial design, in which the first factor is the portion size of a food served to children: foods will be served in a reference amount (i.e. 250 g macaroni and cheese) or doubled in size(i.e. 500 g of macaroni and cheese). In the Experiment 1, the second factor of the 2 x 2 design is meal type: whether the food is consumed at a meal or a snack. In experiment #2, the second factor is food type: fruit vs. vegetable. In experiment #3, the second factor is entree energy density: a regular energy density or a 40% greater energy density. In experiment #4, the second factor is plate size: a 6 inch plate vs. a 10 inch plate.
