摘要: This paper provides a historical summary of military nutrition research into the role diet for sustaining soldier physical performance. Studies underfeeding document that performance is preserved during several days provided sufficient carbohydrate and minerals are consumed to minimize diuresis associated with semi-starvation diets serial intake available support metabolism prolonged work. The Military Recommended Dietary Allowances, AR 40-25, currently recommends when restricted rations required, ration contain at least 1,100-1,500 kcal, 50-70 g protein, minimum 100 on daily basis. low energy diet, however, not recommended subsistence longer than 10 consecutive days. intakes approximately 300-400 will more closely match quantity oxidized meet requirements field operations. Research potential advantages dietary supplements has generally proved advantageous compared eating well balanced diet. Future investigations health should be directed toward better understanding influence macro-nutrient composition preserving lean body mass, reducing susceptibility illness injury enhancing recovery after sustained
