Hunger and Learning Study in Preschoolers

This prospective random controlled cross-over intervention studies is designed to ascertain if children feel different levels of hunger and fullness before and after eating test meals consisting of high-satiety vs. usual foods and if the child's perceived hunger/fullness is related to their salivary ghrelin levels and a variety of learning outcomes. Data are collected at the Diet and Nutrition (DAN) laboratory on repeated study days (8am - 4 pm).
