Elderly
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.
