Six girls between 13 and 14 years of age lived on a controlled diet for 9 weeks. The first two weeks comprised a preliminary period. During the first experimental period of three weeks the mean daily intake of nitrogen was 12.20 gm, corresponding to 76.2 gm of protein. The mean daily amount of nitrogen retained from the diet by the 6 subjects was 1.42 gm, or 0.97 gm per m2, or 29.9 mg per kilogram. During the second experimental period of 4 weeks the mean daily intake was raised to 13.97 gm, corresponding to 87.3 gm of protein. On this diet the mean daily amount of nitrogen retained was 2.17 gm, or 1.45 gm per m2, or 43.7 mg per kilogram. |
