简要总结
This study investigates the effect of varying both energy density and portion size of all foods at lunch on preschool children's intake. The foods used in this study are commercially-available, commonly-consumed foods with typical variations in energy density. The primary aim of the study is to investigate the independent and combined effects of energy density and portion size on preschool children's intake at a meal composed of foods typically served to this population.
