An egg is cracked onto a heated pan and kept in tact: The yolk and the whites are not meant to meddle. The egg is fried on one side until the whites form a solid (signaling that they're fully cooked) and the edges of the whites begin to crisp. The egg is then removed from the pan and served.
Zinc deficiency is characterized by growth retardation, loss of appetite, and impaired immune function. In more severe cases, zinc deficiency causes hair loss, diarrhea, delayed sexual maturation, impotence, hypogonadism in males, and eye and skin lesions [2,8,24,25]. Weight loss, delayed healing of wounds, taste abnormalities, and mental lethargy can also occur [5,8,26-30].
Passing loose, watery stools several times a day is called diarrhea. When a person has diarrhea, he loses fluids and nutrients very quickly. A healthy adult may have diarrhea for a day or two, and will quickly recover. But losing so much fluid and nutrition is dangerous for children, old people, and people already weak from malnutrition or another sickness. Care for children with diarrhea is explained in Chapter 28: Caring for Children.
