The Integrated Impact of Diet on Human Immune Response, the Gut Microbiota, and Nutritional Status during Adaptation to Spaceflight (Food_Physiology)
Principal Investigator
Research Area:
Gastrointestinal physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Given the associations between diet, the gut microbiota, and immune response investigators will be assessing multiple nutritional biomarkers and metabolites, immunological biomarkers, and the gut microbiota in relation to diet and are expecting to associate multiple benefits between nutrient intake and nutritional biomarkers and metabolites in relation to immune and microbiome health. It is expected that by determining shifts in nutritional and immunological biomarkers and the taxonomic and metatranscriptomic profiles of the gut microbiota associated with two different space flight diet regimes investigators may be able to understand how diet impacts human adaptation to space flight, begin to characterize a healthy status in relation to diet, and indicate where alterations in diet may best improve physiological status. This work is significant as the first step towards determining the associated effect of increasing the consumption of specific bioactive compounds, fruits, and vegetables, on human health and adaptation to space flight, specifically related to the immune system and gut microbiota, which will guide future food system development efforts towards efficient dietary interventions and improved overall health, and ultimately the success of long duration human exploration missions.

Human Research Program (HRP) Human Research Roadmap (HRR) Information
Crew health and performance is critical to successful human exploration beyond low Earth orbit. The Human Research Program (HRP) investigates and mitigates the highest risks to human health and performance, providing essential countermeasures and technologies for human space exploration. Risks include physiological and performance effects from hazards such as radiation, altered gravity, and hostile environments, as well as unique challenges in medical support, human factors, and behavioral health support. The HRP utilizes an Integrated Research Plan (IRP) to identify the approach and research activities planned to address these risks, which are assigned to specific Elements within the program. The Human Research Roadmap is the web-based tool for communicating the IRP content.
