1. The seven nitrogen balance studies currently available included a total of 104 men and women; all but 14 of these were healthy, well nourished US subjects. The interpretations are mixed, and some but not all of the reports suggest that the 0.8 g of protein per kg per day may not be sufficient for the maintenance of nitrogen balance. Since the deficits are not large and are not consistent, recommendations must be deferred.

2. The meta-analysis of all available nitrogen balance data on adults to be carried out by Young and Scrimshaw should include data on the elderly and a comparison of these data with those of younger subjects. Specific recommendations for the elderly should await the outcome of this review.
