Aims:
1. Complete a systematic review of the literature to describe the interrelationship of nutrition (and specific nutrients) with CBS systems and risks. Identify potential nutritional countermeasures of relevance to the CBS systems and risks, focusing on how these countermeasures may influence performance outcomes.
a. Development of a comprehensive database of relevant research that allows for an assessment of the methodological quality of included studies.
b. Summarize the extent, range, and nature of nutritional countermeasures that potentially mitigate the individual and synergistic impacts of the three CBS risks.
2. Summarize relevant research findings in order to provide a scientifically plausible rationale for an integrated risk mitigation approach using nutritional countermeasures while addressing the implications for these countermeasures in the context of missionrelated factors (e.g., immune system alterations, food systems) related to crew health and operational performance.
a. Identify research conducted with animals to identify plausible approaches for use of animal models in the identification and validation of nutritional countermeasures for use in the CBS Integrated Research Plan.
3. Identify biomarkers associated with nutrition and nutritional countermeasures and their relevance to a) structural and functional changes to brain, b) associated dose-response
effects related to physiological changes, and/or c) real-time performance outcomes.
4. Use results of this literature-based research to identify gaps in knowledge related to a) potential synergistic effects of deep space travel (e.g., impacts of isolation and confinement and altered gravity, and radiation effects), b) potential use of CMs to prevent or intervene, and c) potential biomarkers for both human spaceflight and translational models. In particular, identify research gaps in the existing literature related to nutritional CMs as they relate to:
- Mechanisms
- Pathways
- Order effects validation
- Biomarkers
- Potential interactions with other countermeasures
- development/refinement of standards

RiskRisk of Acute (In-flight) and Late Central Nervous System Effects from Radiation Exposure
GapCBS-CNS - 1: Are there significant adverse changes in CNS performance in the context and time scale of spaceflight operations? If so, how is significance defined, and which neuropsychological domains are affected? Is there a significant probability that space radiation exposure would result in adverse changes? What are the pathways and mechanisms of change?
GapCBS-CNS - 2: Does space radiation exposure elicit key events in adverse outcome pathways associated with neurological diseases? What are the key events or hallmarks, their time sequence and their associated biomarkers (in-flight or post-flight)?
GapCBS-CNS - 4: What are the most effective medical or dietary countermeasures to mitigate CNS risks? By what mechanisms are the countermeasures likely to work?
GapCBS-CNS - 8: Are there significant CNS risks from combined space radiation and other physiological or space flight factors, e.g., psychological (isolation and confinement), altered gravity (micro-gravity), stress, sleep deficiency, altered circadian rhythms, hypercapnea, altered immune, endocrine and metabolic function, or other?
