Leucine Requirements in School-Age Children

Leucine is an essential amino acid, which serves a special purpose of signaling cell growth in muscle in addition to making up protein. Essential amino acids like leucine need to be eaten every day from our foods like meat, dairy, eggs, beans, and nuts, as they cannot be made by our bodies. The current recommendation for leucine in the diet of school-age children are based upon adult needs. This study will measure the leucine requirement in children aged 6-10 years old using an non-invasive technique with special diets, safe stable isotopes, and simple breath collections. Creating guidelines based on measured requirements for leucine in this age group is essential for supporting optimal growth in healthy children.
