F³ Study - Finding foods fearful: A study of children and adolescents with a fear of trying new foods

If you think your child has a fear of trying new foods and/or has such a limited food variety that it gets in the way, join our online registry of parents who have a child who struggles with food neophobia.  Your responses will help us to learn more about this behavioral pattern so we can develop new treatments, help parents feel less blamed, and learn more about the development of taste preferences in general.
