Deficiency Diseases

Diseases that occur due to lack of nutrients over a long period are called deficiency diseases or nutritional disease. Deficiency of one or more nutrients can cause diseases or disorders in our body. For example, wheat is rich in carbohydrates, but poor in nutrients like proteins and fats. Too much intake of wheat products results in a deficiency of proteins and fats, which reduces growth. Lack of proteins also results in stunted growth, skin diseases, swelling of the face and discolouration of the hair, and even causes diarrhoea. 

Deficiency of different vitamins and minerals may also result in certain diseases or disorders. So a balanced diet is required to avoid deficiency diseases. Some diseases/disorders caused by deficiency of vitamins and minerals.
