In order to study food habits in a controlled isolation environment the food choice and consumption behavior of the crew of a simulated, isolated- duty station were measured in a nine-day experiment. All crewmembers completed food preference survey forms and kept daily food consumption diaries. Food selection and consumption in grams were measured for each crewmember. Crewmembers displayed a fairly common pattern of intake during a day with approximately 19 of their calories obtained from breakfast, 30 from lunch, 35 from dinner, and 16 from snacks. There appeared to be no systematic shifts in probability of selection for either food classes or individual items as a function of the duration of the experiment. The best general predictor of food item choice was the preferred frequency rating from a survey completed during habitation. In comparing actual and recorded food items were more often due to failure to record items in the diary. Errors in estimating the amount consumed tended to be over-estimations if the food item was a solid and under-estimations if the item was a liquid.
