Choosing plants to be grown in a Controlled Environment Life Support System (CELSS) based upon attractive vegetarian diets.
Space explorers on the Moon, Mars, or even in a space craft might grow plants in a CELSS to remove CO2 and provide O2 and food.  Selection of crops to be studied has been rather arbitrary but should be based on plants that can provide a balanced and attractive, mostly vegetarian diet.  Additional selection criteria include ease of growth in artificial environments and sufficient variety provided over long intervals.  This article is based on a workshop convened to study vegetarian diets for use in a CELSS.  Participants included nutritional scientists, practicing vegetarians, and interested employees of the Johnson Space Center.  It was concluded that diets meeting the criteria could be formulated, and a list of suitable crops was compiled.
