From June 22, l955, through July 27, l955, 100 volunteer airmen served as subjects in a study of survival rations in moist heat at Camp Atterbury, Indiana. To establish physiological, biochemical, initritional, and clinical jndgnLents on the relative effects of work, water, calories, and proteincarbohydratefat ratio in all-purpose survival rations, numerous observations were made in two-week periods of adequate, restricted, and recovery diets, with luxus amounts of vitamins at all times. Twenty-one nutrient combinations could be rank-ordered, by 27 different tests, with respect to effects on organ function and body efficiency. Clinical findings could also be rated. By far the best regimen was that represented by the ideal control--Field Ration A. Of the experimental regimens, the worst was starvation the best was a 3000 Calorie adequate ration. Below the 3000-Calorie ration, the highest score was attained both in hard work and in light work by a combination supplying unlimited water, 2000 Calories per day, and a distribution of calories of 15 protein, 52 carbohydrate, and 33 fat. Limitation of water, decrease of calories, or marked deviations in proteincarbohydratefat ratios resulted in measurable clinical or functional deterioration.
