An evaluation of the essential amino acid intake was conducted on the data of the Nutrition Survey carried out in the Japanese fishing village, 1959, and the results obtained were summarized as follows:
1) An average daily intake of protein was 89.1g (man value), about 10% higher than the standard value, and any of the essential amino acid intake was greater, as compared with the value calculated from the Standard Food Construction of Japanese people. As for Lysine and Methionine, more than 50% of each of them was supplied with animal foods (Fish and Fishshell), and so their intake showed an upward tendency with the increase of animal protein coefficiency.
2) In comparing the intake of the essential amino acid with the Provisional Protein Pattern (FAO), the intake of, Methionine, Sulfurcontaining amino acid, and Tryptophan was always low, their mean percentage being, 85, 78, and 70 respectively.
Especially the intake of Tryptophan was lowest, the first limiting amino acid; this may be attributed to the fact that animal protein was supplied most with fish and fishshell, and least with eggs and meats.
