Nutritional Biochemistry of SpaceflightAdequate nutrition is critical for crew health and safety during spaceflight. To ensure adequate nutrition, the nutrient requirements need to be both accurate and available from the spaceflight food system. The existing nutritional requirements for extended-duration spaceflight have been defined largely by extrapolation from ground-based research. However, nutritional requirements are influenced by most of the physiological consequences of spaceflight, including loss of lean, adipose, and bone tissue; changes in blood composition; and increased risk of renal stone formation. This review focuses on key areas where information has been gained in recent years: dietary intake and energy metabolism, bone health, fluid and electrolyte homeostasis, and hematological changes. Areas in which specific nutrients have the potential to serve as countermeasures to the negative effects of spaceflight are also reviewed. Dietary Intake
