Potatoes as a Strategy to Improve Diet Quality in Young Children

Обзор

The purpose of this study is to examine whether incorporating potatoes into meals-either paired with other vegetables or served as a first course-can improve preschoolers' vegetable intake, reduce excess energy intake, and improve overall diet quality. Findings will be used to inform whether potatoes, a well-liked and commonly consumed vegetable, could be leveraged in several ways to improve the overall diet quality of children.

Подробное описание

The overall object of this study is to test potato-based strategies to improve diet quality in preschool age children. The specific aims are:

Aim 1: Determine if pairing potatoes with other less-preferred vegetables increases liking and intake of the non-potato vegetables.

Aim 2: Determine if potato-based dishes can be used strategically to reduce intake of more energy-dense entrees.

The effect of potato-based dishes on vegetable intake and total energy intake will be tested across four lunch-time sessions in preschool classrooms. Each lunch session will be randomly assigned to one of the potato dish conditions.
