  • The composition of diet should be as follows:
  1. Protein intake of 0.8 g/kg for sedentary individuals; 1.2 to 1.5 g/kg for those performing strenuous endurance activities (Meredith et al., 1989) (result is about 12 to 15 percent of total energy intake).
  2. Carbohydrate intake should supply around 60 percent of total energy intake to cover increased need for carbohydrate in the adequately fed individual. This carbohydrate should be consumed as complex forms to minimize gastrointestinal distress.
  3. Fat intake could be as low as 25 to 28 percent, and such levels of intake may decrease some of the intestinal distress that may accompany large intakes of simple carbohydrate (Worme et al., 1991).
  • Develop a drinkable, high-carbohydrate, moderate protein and fat supplement containing about 500 kcal; inclusion of such a product in the rations of sojourners at altitude will help to remedy the consequences of increased need and decreased appetite.
  • Determine amount of diuresis that is necessary for optimal adaptation to altitude. Provide fluid sufficient to cover high insensible losses and diuresis (4 liter/d).
  • Determine the possible positive effects of feeding on the development of symptoms of acute mountain sickness. Evaluate the effect of meal composition on these symptoms.
