    Malnutrition is the condition that develops when the body is deprived of vitamins, minerals, and other nutrients it needs to maintain healthy tissues and organ function.

    Malnutrition occurs in people who are either undernourished or overnourished. Today, in the U.S., more children suffer from malnutrition due to dietary imbalances rather than nutritional deficiencies.

    Undernutrition occurs when not enough essential nutrients are consumed or when they are excreted more rapidly than they can be replaced. Overnutrition occurs in people who eat too much, eat the wrong things, don't exercise enough, or take too many vitamins or other dietary replacements. Risk of overnutrition is increased by being more than 20 percent overweight or consuming a diet high in fat and salt.

    About 1% of children in the United States suffer from chronic malnutrition.

    Malnutrition is when your body is not getting the calories, fats, vitamins and minerals that it needs to operate on a daily basis. Your body is like a car engine, and when it's running low on gas or on the "reserve tank" (aka using your fat and muscle stores), it won't run the way it's supposed to.
