摘要:The authors investigated the calorie and protein intake over one year with pupils in dormitories in senior high school (29 males; 17 females, aged from 15 to 18 years) in association with observations of their physical fitness and structure. 1) The calorie intake was 2, 670 Cal.(males) and 2, 280 Cal.(females) per day on average. The calorie consumption per day calculatedfrom the investigation by the time-study method was 2, 390 Cal.(males) and 2, 040 Cal (females) on average. The differences between these two categories were about 10% of the calorie intake which may correspond to calorie consumption due to S.D.A. and the growth. 2) The protein intake was 90g/day (1.6g/kg) with male and 72g/day (1.4g/kg) with female and the protein score was 72 to 75, the limiting amino acid being tryptophan. 3) The rate of growth of height, body weight and physical strength of these pupils in a year was about the same or a little higher as compared with the standard rate of Japanese young people of the same age. 4) The calorie and the protein intakes of these pupils are a little lower than the levels of the recommended allowance of the Japanese revised at 1957. Therefore, it is concluded that the revised recommended daily dietary allowance can fulfil the physiological requirements of calorie and protein which enable the present standard rate of Japanese high teen agers.
