Note: LxC is the likelihood and consequence rating. This risk is mapped to the official (consolidated) HSRB risk "Risk of Performance Decrement and Crew Illness Due to Inadequate Food and Nutrition". At this time, only Planetary risk ratings colors are being assessed for this risk within HRP for PRR purposes. All Risk Dispositions are assigned by the HSRB for the consolidated risk.
Risk Statement
Given that adequate nutrition is a key factor in all physiological functions, that space flight has been shown to alter many physiological functions in humans, and that countermeasures for individual systems may alter nutritional status, there is a possibility that inadequate nutrition will compromise crew health, including endurance, muscle mass and strength, immune function, bone mass and strength, cardiovascular performance, gastrointestinal function, endocrine function, and ocular, psychological and physical health, and ability to mitigate oxidative damage.
