Abstract : 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 protein/carbohydrate/fat 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 protein/carbohydrate/fat ratios resulted in measurable clinical or functional deterioration.
