The eating experience will increase in importance on longer missions as pathways are sought to ensure adequate nutritional intake and minimal stress.  AFT, in coordination with the Behavior Health and Performance (BHP) team, is pursuing methods to enhance the eating experience on orbit.  The proposed work will investigate impacts of aspects of food on mood, and the variety of foods normally consumed over time across free-living individuals.

The suggested aims of this evaluation are: 

  1. To identify “trigger” foods and occasions to define when mood evaluations will be taken.
  2. To determine the relative impact on mood when trigger foods are provided in varying initial mood states.
  3. To determine the effect of communal dining as compared to solo dining on mood state.
  4. To determine the role of food preparation on mood and stress.
  5. To recommend  dining behaviors and practices that positively affect the mood, stress, and behavior of crew on extended missions.
  6. To determine whether the amount of food variety consumed differs by eating occasion or by day and which foods are eaten with relatively higher frequency both within individuals and across individuals, and how this compares to current spaceflight food variety.

The project will partially fill the gap of an acceptable food system in that it can provide guidelines on the relationship of food to mood, and on food variety that would be expected and normally consumed.
