Initial State of Gap: There has been little effort to relate nutritional status with behavior and performance.  The scientific literature is replete with evidence of the interrelated nature of nutrition, behavior and performance.  Furthermore, historical records document the importance of food and nutrition on exploration missions.  

Interim steps: 

      1. Identify measures of behavioral health and performance, cognition, or biomarkers that can be related to dietary intake and nutrition (with BHP).
      2. Track detailed dietary intake and nutritional status assessment data and relate to behavioral health and performance. 
      3. Identify any significant elements of diet or nutritional status, above and beyond macro and micronutrient requirements from N3.1 and 3.2, that impact behavioral health and performance. 
      4. Steps  1-4 will be repeated yearly.  This gap will progress to completion at the end of ISS. [100% completion at end of ISS].

Approach: Review literature to identify relationships between nutrition and behavior.  In addition, the approach will involve analysis of retrospective and current nutrition and BHP biomarker and Immune data from flight experiments.  The approach will also include identification of nutritional biomarkers related to BHP for analysis in future flight studies.

Target for Closure
Determine which aspects of dietary intake, if any, relate to behavior and performance during long-duration space flight. 
Risk Risk of Performance Decrement and Crew Illness Due to Inadequate Food and Nutrition
You are here! Gap N7.4: We need to identify the most important nutritional factors for behavior and performance.
