Clinical syndromes due to altitude can manifest in susceptible individuals with elevations as low as 1500 meters (5000 feet) above sea level. For otherwise healthy adults, altitudes of 2350 meters (8000 feet) are considered the arbitrary cutoff for placing one at risk for more serious syndromes, such as acute mountain sickness (AMS). While decreased ambient oxygen pressure is the most evident change at high altitude and presumably is responsible for most of the pathophysiologic derangements, other factors may have medical implications as well, such as decreased ambient temperature, increased exposure to ultraviolet radiation, and lower humidity.

At first glance, it might seem obvious that people in the United States need MVIs. Since the 1970s, there has been a steady decline in intake of fruits and vegetables, followed closely by an increase in intake of nutrient-poor, high carbohydrate foods.7 In 2005, the CDC estimated that only 32.6% of adults consumed fruit two or more times per day and only 27.2% ate vegetables three or more times per day.8 A low fruit and vegetable intake becomes increasingly more likely in the elderly due to poor appetite, eating disability, and underlying pathology.9 Even with an adequate intake of fruits and vegetables, it may be difficult to meet daily recommended intakes (DRI)due to changes in nutrient content of foods, which can depend on the food’s origin and subsequent processing. For example, some frozen vegetables may lose up to 95% of their folate content after being frozen for only 3 months.10 Another analysis found that the content of nutrients in dehydrated fruits and vegetables drastically decreased after a shelf life of 3 months.11
