TI  - Influence of a carbohydrate drink on nutritional status, body composition and 
      mood during desert training.
PG  - 37-44
AB  - BACKGROUND: Nutritional intake by military personnel is typically inadequate 
      during field exercises, potentially compromising health and performance. 
      HYPOTHESIS: Drinking a supplemental carbohydrate (CHO) beverage will increase 
      total caloric intake and maintain nutritional status during military training in 
      the desert. METHODS: A total of 63 volunteers were randomly assigned to one of 
      two groups to receive either a CHO or placebo beverage with military rations 
      during an 11-d desert field exercise. Fluid intake was ad libitum and adequate 
      rations were provided. Blood samples were collected twice to assess nutritional 
      status, and nutrient intake was determined with consumption data. Mood state was 
      examined by questionnaire. RESULTS: Energy intake was significantly higher in the 
      CHO group (3050 kcal x d(-1) vs. 2631 kcal x d(-1)), with additional CHO from the 
      beverage providing energy with some compensation by reduced fat and protein 
      intake. Intakes of energy, folacin, calcium, magnesium, iron, and zinc in both 
      groups were inadequate, with intakes significantly lower (p<0.05) for calcium, 
      magnesium, and zinc in the CHO beverage group. Blood parameters of nutritional 
      status remained within normal ranges with no differences between groups, but 
      significant decreases were seen in pre-albumin. No changes in mood were seen 
      during the training, nor after exposure to desert conditions. CONCLUSIONS: The 
      operational ration supplemented with a CHO beverage significantly increases CHO 
      and energy intakes compared with standard rations and maintains nutritional 
      status for short exercises. Fortification with micronutrients most at risk for 
      deficient intake from foods may be needed for longer deployments.
