When energy intake falls below needs, a variety of problems arise-physical and mental activity declines; growth slows or ceases altogether; muscle and fat wasting occurs; the immune system weakens, increasing susceptibility to disease; and death rates rise (Fig. 3-1). The consequences of micronutrient deficiencies can be equally devastating. For example, vitamin A deficiency, found in approximately 30% of children under age 5 in developing countries, damages the eyes and sometimes causes blindness. Vitamin A deficiency also increases vulnerability to common diseases, such as measles, diarrhea, and respiratory infections. Iodine deficiency is the world's leading cause of preventable mental retardation and brain damage. Vitamin A, iodine, iron, zinc, and folate are the micronutrients most likely to be in short supply in developing countries.
