Nutrition and Metabolism in Spaceflight1

Philip L. Altman and John M. Talbot

Life Sciences Research Office, Federation of American Societies for Experimental Biology, Bethesda, MD 20814

The United States Space Station being planned for the 1990s will accommodate six or more crew members on 90-d flights in low earth orbit. Adequate nutrition will be essential for maintaining crew health, effectiveness and morale. Although much is known from prior space experience about in-flight metabolism, nutrition and associated food technology, important gaps in knowledge exist that need additional research, development and analysis to meet Space Station requirements. This paper is a synopsis of a report prepared by the Life Sciences Research Office (LSRO), FASEB, from a study of the nutritional and metabolic aspects of spaceflight. It reviews available data on the metabolic responses to spaceflight including extravehicular activity, physiological responses to microgravity that influence metabolism and energy needs, in-flight nutritional experience, space menus, food packaging, in-flight food service methodology, water supply and disposal of food wastes. The LSRO ad hoc Working Group identified critical gaps in knowledge and suggested corresponding research approaches for acquiring essential new data. The 38 research suggestions detailed in the report address in-flight metabolic needs, nutrient requirements, food systems and nutritional countermeasures.

KEY WORDS: • nutrition • metabolism • spaceflight

1 Synopsis of a report from the Life Sciences Research Office, approved by the LSRO Advisory Committee of the Federation of American Societies for Experimental Biology.
