THE EFFECT OF A LIQUID FOOD DIET ON HUMAN SUBJECTS IN A LIFE SUPPORT SYSTEMS EVALUATOR

A 6-week study with four college students as volunteer subjects was conducted for the purpose of evaluating the water, caloric and protein requirements of individuals undergoing simulated stresses of aerospace conditions. During this time the subjects spent 28 days in the Life Support Systems Evalua...

description A 6-week study with four college students as volunteer subjects was conducted for the purpose of evaluating the water, caloric and protein requirements of individuals undergoing simulated stresses of aerospace conditions. During this time the subjects spent 28 days in the Life Support Systems Evaluator. Two subjects wore the MA-10 space suit, unpressurized for 24 hours a day. The subjects ate a 1-cycle, 4 meals per day fresh food diet and a 3-cycle, 4 meals per day liquid food diet. The only variety in the fresh food diet was the meat and fruit served at each meal. This diet was acceptable and did not show monotony even after 21 days. The fresh food diet was comprised of 63 g protein, 150 g fat, 204 g carbohydrate and 2372 kcal energy. The liquid food diet was composed of 70 g protein, 167 g fat, 246 kcal energy. The daily requirement of water was about 2700 ml for both diets. (Author)
