Define protein requirements of Preschoolers?

For Preschoolers the protein requirements of children of various age groups are computed by the factorial method as employed by FAO/WHO/UNU Expert Consultation (19.85). The factorial value is increased by 50% to obtain the physiological  requirements for growth and further 25% (mean + 2 SD) has been added to give the  safe levels of intake. The RDA of protein additionally considers a NPU value of 65 for dietary proteins. Body weights of well-to-do Indian children have been used for computing their protein intakes. Long-term nitrogen balance studies have supported the values obtained by this factorial method. The RDA for proteins, along with other nutrients is given in Table.
