INVESTIGATIONS ON MINIMUM ALBUMIN CONSUMPTION IN MAN UNDER HEALTHY AND PATHOLOGICAL CONDITIONS,

In determining the minimum albumin consumption, the food N must never exceed the minimum N to be expected. In the adult, the nitrogen minimum is twice as high as the minimum albumin consumption. This increase is mainly found in the urea. In the growing human being, the minimum albumin consumption and the nitrogen minimum coincide. The synthetic capabilities of the youthful organism are far superior to those of the adult organism. The biological value of milk is therefore much greater in the growing individual than in the fully grown individual. The lowest minimum N is often reached only at the beginning of the 2nd week of N-free diet. It is not absolutely constant but varies with the calorie intake. The energy requirements during bed rest are calculated at about 150 of the basal metabolism. To a calorie supply calculated in this manner there corresponds a minimum N of about 1.2 - 1.3 g N per sq m and per day. If we supply 300 calories of the basal metabolism, the minimum N drops to about 0.9 g N per sq m and per day. Comparisons of the minimum albumin consumption in various individuals are possible only if the calorie intake is the same, related to the pertinent basal metabolism and assuming that the experiments last an equal amount of time. The relationship between the minimum albumin consumption and the body surface reveals a much greater constancy in the various age brackets than the relationship to the body weight and to the albumin amount of the organism.
