Which age group has the highest demand for protein?

The age group that has the highest demand for protein is typically infants under 1 year. Infants require significant amounts of protein relative to their body weight to support rapid growth and development during this critical stage. Their protein needs are crucial for building tissues, supporting immune function, and overall metabolic processes.

While children aged 13 months to 12 years certainly have growing bodies and require protein for growth and development, their specific protein needs are generally lower per kilogram of body weight compared to those of infants. Additionally, protein requirements in adults aged 18-30 and senior citizens also reflect growth and maintenance needs but do not surpass the high demands placed on infants.

In summary, the intensity of growth and developmental changes occurring in infants leads to their need for a higher quantity of protein, making this age group the one with the highest overall demand for protein.
