[Nutrition of crews of long-term missions on the International Space Station].

: The integrated Russian-US rations consumed by seven crews of the ISS long-term missions were subjected to hygienic and sufficiency evaluation. The rations were found to contain the necessary quantities of all nutrients. As concluded from the analysis of anthropometrical, physiological and biochemical investigations performed in flight, they supported crew energy and plasticity needs and were a contributing factor in the high level of performance.
