Effect of Varying Proportions of Low and High Energy Dense Foods Over 5 Days in Preschool Children

2017-08-08 14:23:21 | BioPortfolio


In this study, the investigators will vary the proportions of high- and low-energy-dense foods served to preschool children at all meals and snacks during three 5-day periods. In the three experimental conditions, the same foods will be served; only the amounts and proportions of foods will be varied. In the Baseline condition, typical proportions of age-appropriate foods will be served. In the Addition condition, the portion sizes of low-energy-dense foods will be increased, and in the Substitution condition, the portions of low-energy-dense foods will be increased by replacing an equivalent amount of foods higher in energy density. The primary aim is to determine the effect on children's energy intake of varying the proportion of low- and high-energy-dense foods served, either by addition or substitution, over 5 days. It is hypothesized that children will consume less energy when they are served meals in which low-energy-dense foods are substituted for foods higher in energy density over 5 days and that children will consume more energy when served meals to which low-energy-dense foods are added. Additionally, we will test the hypothesis that daily energy intake in the three conditions will begin to converge across the 5-day period.

Medical and Biotech [MESH] Definitions

Behavioral responses or sequences associated with eating including modes of feeding, rhythmic patterns of eating, and time intervals.

Animal searching behavior. The variable introductory phase of an instinctive behavior pattern or sequence, e.g., looking for food, or sequential courtship patterns prior to mating.

Instinctual behavior pattern in which food is obtained by killing and consuming other species.

Nutritional support given via the alimentary canal or any route connected to the gastrointestinal system (i.e., the enteral route). This includes oral feeding, sip feeding, and tube feeding using nasogastric, gastrostomy, and jejunostomy tubes.
