In children aged 0-2 years, what is the expected protein need per kilogram per day?

For children aged 0-2 years, the expected protein need is approximately 2-3 grams per kilogram per day. This requirement is supported by the physiological demands of rapid growth and development occurring during this critical period. Infants and toddlers are in a stage of life where their bodies are rapidly developing tissues, including muscles and organs, which necessitates higher protein intake compared to older children and adults.

This increased protein requirement also takes into account the fact that infants have a higher turnover of body proteins, meaning that they need a consistent supply of dietary proteins to maintain their growth and health. Additionally, during this age, the diet may consist of breast milk or infant formula, which is designed to meet these nutritional needs effectively.

In contrast, other choices reflect protein needs that do not align with the established nutrition parameters for this age group. While the choices under 2 grams per kilogram per day would be insufficient for their growth demands, the higher range might suggest excessive protein intake, which is not typical for this age group. Thus, the proper protein intake of 2-3 grams per kilogram per day is key to supporting healthy development in early childhood.
