Additional Study Information: Our mission is to learn about nutrition and the developing adolescent brain. All our research also includes healthy teenagers. This study is looking for healthy teenagers between the ages of 14 and 18 years to participate in a study about food. As a participant in our study, your child would: (a) complete a series of questionnaires and interviews, (b) complete an MRI (no radiation), and (c) several research assessments of food intake. These procedures would be repeated 1 year later, and she can earn up to $225 each time. To be eligible for this study, adolescents must be 14-18 years old, female, and no history of a diagnosis of an eating disorder.
