Under normal conditions, we all lose some body water every day in our sweat, tears, urine, and stool. Water also evaporates from skin and leaves the body as vapor when we breathe. We usually replace this body fluid and the salts it contains with the water and salts in our regular diet.
Sometimes, however, kids lose large amounts of water and salts through fever (more water evaporates from the body when body temperature is increased), diarrhea, vomiting, or long periods of exercise with excessive sweating. Some illnesses might also prevent them from taking fluids by mouth. If they're unable to adequately replace the fluid that's been lost, kids can become dehydrated.
Bringing sniffles and sneezes and perhaps a sore throat and annoying cough, the common cold catches all of us from time to time.
With kids getting as many as eight colds per year or more, this contagious viral infection of the upper respiratory tract is the most common infectious disease.
Few kids would say they crave a good fiber-rich meal. Although the thought of fiber might bring gags and groans from kids, many appetizing foods are actually great sources of fiber — from fruits to whole-grain cereals. And kids are probably eating them without even knowing it.
