This study will characterize key effects of the current space flight diet compared to an enhanced space flight diet on immune function, the gut microbiome, and nutritional status indicators to begin comprehensively documenting the effect of dietary improvements on human physiology and their ability to enhance human adaptation to space flight. Blood, urine, saliva, and fecal samples will be collected at multiple time points pre-, in-, and post-flight along with body mass/height, exercise, and medication data. A consultation will occur with each crewmember prior to launch to discuss an enhanced diet equal to 25% of his or her total food inflight. The enhanced diet will contain an increased selection of fruits, vegetables, omega-3 fatty acids, lycopene and flavonoid rich foods. Food intake will be tracked each day during the duration of a crewmember’s inflight mission, and will be collected over five days via a weighed diet record during each baseline data collection session. The investigators will have a weekly inflight conference with the crewmember to discuss his or her diet throughout the mission, as well as a post-flight nutritional data discussion.
This experiment is in progress. Results will be available at a later date.
