Description
OBJECTIVES:
The three inter-related foci in this proposal explore factors that contribute to the long-term acceptability of a diet, in terms of satisfaction with and sufficient consumption of the foods, as well as associated moods and stress levels. The objective of the first focus is to examine behaviors related to preparing and consuming meals. Understanding the relation between preparation effort and the acceptability and consumption of the prepared food, as well as effects on moods and stress, will inform decisions on the amount of time and types of activities crewmembers should allot to meal preparation. Understanding the relations between communal dining and special occasion meals and moods and stress will allow recommendations for dining behaviors that maximize positive moods and minimize stress.

To do this investigators will separately manipulate food preparation effort, food preparation creativity, and the number of people eating together. They will measure the fluctuation in participants' moods and stress levels using questionnaires and physiological measurements. Meal and food acceptability will be measured using a variety of subjective rating scales.

The objective of their second focus is to assess whether comfort foods repair individuals’ moods, and if so, whether comfort foods are more effective than control foods at repairing moods. Understanding the effects of specific foods on crewmembers’ food consumption, stress, and moods will inform decisions on the quantities of such mood-improving foods that should be made available on long 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.

The Human Research Roadmap is located at: https://humanresearchroadmap.nasa.gov/
