Malnutrition

Malnutrition Malnutrition is an unhealthy physical condition resulting either from a faulty or inadequate diet (i.e. a diet that does not supply normal quantities of all nutrients) or by the body’s inability to absorb or metabolize nutrients. Primary malnutrition results when the body gets too much food, not enough food, or the wrong kinds of food. When certain foods containing one or more of the essential vitamins or minerals are not included in the diet, it commonly leads to micronutrient-deficiency diseases. Poor eating habits and food preferences may lead to malnutrition through the habitual consumption of certain foods to the exclusion of others or of large quantities of non-nutritious foods. Secondary malnutrition occurs when, because of acquired or inherited metabolic defects, notably those involving the digestive tract, liver, kidney, and red blood cells. These defects cause malnutrition by preventing the proper digestion, absorption, and metabolism of foodstuffs by organs and tissues, the body is then unable to use nutrients even though they are present in the food. Obesity and starvation are extreme forms of malnutrition. Obesity occurs when people eat much more food than they need.
