Abstract
Protein score (FAO score, FAO 1955) was compared with chemical score (egg score and human milk score, FAO/WHO 1963) and E/T ratio in hospital diet for children.
1) Diet protein value judged from “common sence” was better correlated with FAO score than egg score or human milk score.
2) It is not so easy to evaluate protein using chemical score and E/T ratio as mono-dimentional value. As a simple method for protein evaluation, it may be convenient to use mono-dimentional scoring system.
3) To evaluate diet for infants and young children which contain milk and its products, use of the human milk score may be more suitable than the egg score.
4) The limiting amino acid of the egg score is tryptophan and that of the human milk score is usually S-containing amino acid. It may be more rational to use an intermediate pattern as a reference protein.
