Define protein requirements of children up to age of 2 years?

Infants and children up to age of 2 years should consume about 40% energy from fat (i.e. 40 en%). Fat is an important part of the infant's diet because of its energy density and has a vital role in the: development of the nervous system. Fat resolves a potential problem of infant's high energy needs and small gastric capacity. The linoleic acid requirement of preschoolers is 3 en%, which can be satisfied by a minimal intake of 10 g/d of visible fat. However, more fat is needed to decrease the bulky cereal-based diets; hence upto 25 g/d of visible fat can be given. Total fat Content of the diet increases due to the invisible fat present in milk, nuts, cereals  and pulses.
