Traveling to high altitudes over 2500 m for several days can alter nutrient needs. This review examines evidence for increased requirements and suggests appropriate nutritional strategies for high-altitude environments.

Area of Science:

  • Environmental Physiology
  • Human Nutrition
  • Altitude Medicine

Background:

  • Exposure to terrestrial altitudes above 2500 m triggers physiological adaptations.
  • These adaptations can significantly impact nutrient requirements, both acutely and long-term.

Purpose of the Study:

  • To review the evidence for altered nutrient requirements at high altitude.
  • To provide recommendations for appropriate nutrient intake in high-altitude settings.

Main Methods:

  • Literature review of studies on high-altitude physiology and nutrition.
  • Analysis of nutrient requirements including energy, macronutrients, water, vitamins, and minerals.

Main Results:

  • High altitude exposure increases requirements for certain nutrients.

  • Anorexia at high altitude can impede adequate nutrient intake.
  • A specific food and water regimen ('doctrine') is proposed to address these challenges.

    • Conclusions:

    • Nutritional strategies must be adapted for individuals traveling to high altitudes.
    • Understanding and managing nutrient intake is crucial for health and performance at altitude.
