Ready to Use Therapeutic Food (RUTF) to Promote Growth in Cystic Fibrosis

Study Overview
=================
Brief Summary
-----------------
Children with cystic fibrosis require increased caloric intake to maintain appropriate growth, an important determinant of long-term outcomes. This study seeks to determine the feasibility of using a novel therapeutic food to promote weight gain and growth in children with cystic fibrosis.
