[Adequacy of the protein component of the rations for the crew of orbital station "Sal'iut-6" with respect to bodily requirements].

Nitrogen metabolism in 16 test subjects and 8 cosmonauts kept on a diet containing dehydrated products and foodstuffs preserved by other methods (15% and 85%, respectively) was studied. The health state and excretion of end-products of nitrogen metabolism in those people gave evidence that the dietary protein met well bodily requirements under normal conditions, in simulated flight, and in real flight aboard Salyut-6.
