Describe deficiency disorders which cause malnutrition.
Answers
Malnutrition may be the result of several conditions. First, sufficient and proper food may not be available, because of inadequate agricultural processes, imperfect distribution of food, or certain social problems such as poverty or alcoholism. In these instances, the cause of malnutrition is most often found to be a diet quantitatively inadequate in calories or protein.
Malnutrition may also result when certain foods containing one or more of the essential vitamins or minerals are not included in the diet. This commonly leads to specific nutritional deficiency diseases. Aging, sickness, and other factors that contribute to poor appetite can result in inadequate food consumption. Likewise, 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.

A nutritional deficiency occurs when the body doesn't absorb or get from food the necessary amount of a nutrient. Deficiencies can lead to a variety of health problems. These can include digestion problems, skin disorders, stunted or defective bone growth, and even dementia.
