According to the World Hunger Education Service, there are about 815 million hungry people in the world, or more than 10 percent of our population. Hunger isn?'t just a problem in far-away places that you see on TV. In fact, about one in six American kids don'?t know where their next meal will come from. A regular lack of food-or, sometimes, too much unhealthy food-can result in the condition called malnutrition.
