Nutrition and Hydration Status of Soldiers Consuming the 18-Man Arctic Tray Pack Ration Module with Either the Meal, Ready-to-Eat or the Long Life Ration Packet during a Cold Weather Field Training Exercise
This lO-day test evaluated two Army Field Feeding System feeding modalities (T/MRE/T and T/LLRP/T) with 96 male soldiers participating in a cold weather field training exercise. Nutrition/hydration status was assessed from food/fluid intake, body weight and percent fat changes, and urine specific gr...
