School children will have a good appetite but their food should be selected nutritiously. During 6 to 12 years the rate of growth in children slows down and body changes occur gradually. This period of life in general is known as the latent period of growth. This is applicable mainly for boys. In girls prepubertal acceleration of growth take place during later half of this period. During this stage girls usually outgrow boys. The body requirements of calories and protein are increased steadily. Requirements of the nutrients of children are increased from 7 - 12 years, as there is gradual increase in need because reserves are being laid down for the demands of the approaching adolescent period. The increased requirements of protein would meet demands of the growth. Girls require more protein between 10 - 12 than boys do, since they are approaching menarche early. During 10 - 12 years, children do require more calcium than adults to meet demand for skeletal growth. Since blood volume is increased iron requirements are also increased.
