What is the protein need for children aged 3-15 years according to ASPEN recommendations?

The recommendation of 1.5 g/kg for protein intake in children aged 3-15 years is grounded in the increased nutritional requirements during this critical growth period. Children in this age range experience rapid growth, increased muscle mass, and the transition of various physiological systems, all of which necessitate a higher intake of protein.

Protein is essential for growth, development, maintenance of body tissues, and the synthesis of hormones and enzymes. The 1.5 g/kg recommendation reflects the need to support both lean tissue growth and overall metabolic functions effectively. Adequate protein intake also plays a vital role in immune function and overall health, which is particularly important as children become more active and engage in physical learning environments.

This recommendation can help guide dietary planning to ensure that children receive sufficient protein from a variety of sources, including animal and plant-based foods, thus supporting their health and developmental needs. In contrast, lower protein recommendations would not meet the demands of children in this growth phase, potentially leading to deficiencies that can adversely affect their growth and health outcomes.
