What is the range of protein needs per kilogram per day for children aged 2-13 years?

For children aged 2-13 years, the range of protein needs is approximately 1.5-2 grams per kilogram of body weight per day. This requirement reflects the increased protein needs during periods of rapid growth and development. During these years, children's bodies are not only growing taller and heavier, but they are also developing muscle, organ systems, and neural tissues, all of which necessitate adequate protein intake.

Protein plays a crucial role in numerous physiological functions, including the building and repair of tissues, synthesis of enzymes and hormones, and supporting immune function. The recommended dietary allowances (RDAs) for protein are established to ensure that children receive enough essential amino acids for optimal growth and development.

In this age group, dietary sources of protein should ideally include a variety of foods such as meat, fish, poultry, eggs, dairy products, legumes, nuts, and seeds to cover both protein needs and other nutritional requirements. This balanced intake helps promote not just sufficient protein levels, but overall health and development.
