What does malnutrition mean? Explain its causes and write the name of two diseases caused by them?Answer
Malnutrition can be defined as a physical condition of a person in which he suffers from a disease, due to lack of nutrients, such as carbohydrates, proteins, fats, minerals and vitamins. In short, the condition arising out of improper nutrition and unbalanced diet is called malnutrition. The main cause of improper nutrition and unbalanced diet is poverty. Malnutrition retards the physical and mental development of children. Some deficiency diseases can also be called as nutritional diseases.
Deficiency disease can be classified into the following categories:
- Protein Energy Malnutrition (PEM)
- Vitamin deficiency diseases.
- Protein Energy Malnutrition: Growing children need more protein. The children between the age group, 1-5 years are affected by protein malnutrition. Protein malnutrition leads to two types of diseases, namely Kwashiorkor and Marasmus. Kwashiorkar is caused due to deficiency of protein, which develops when mothers stop feeding the babies with their protein-rich breast milk.
What is a Balanced diet? What is the role of minerals in balanced food? Explain the disease caused by the deficiency of minerals?
A balanced diet is one, which contains a variety of food in such quantities and proportions so that the need for energy, amino acids, vitamins, minerals, water and roughage is adequately met for maintaining health, vitality and general well-being. Thus, human diet includes carbohydrates, fats and proteins in the ratio of 4:1:1, vitamins, minerals, water and roughage in adequate amounts for maintaining good health.
Role of Minerals: Minerals are the elements which are required in our body in small amounts, with food. These regulate various metabolic activities in our body. Deficiency of a particular mineral causes specific diseases such as anaemia, goitre, rickets, etc.
The main minerals are calcium, phosphorus, sodium, potassium and magnesium. Trace elements which are required in few mg amounts per day are iron, iodine, fluorine, zinc, copper, cobalt, chromium and manganese prominent minerals. Mineral deficiency disease: Anaemia is caused due to the deficiency of iron in the food. Deficiency of iodine causes goitre. Deficiency of calcium creates weakness in bones.

Why is AIDS considered to be a ‘syndrome’ and not a disease?
Full form of AIDS is Acquired Immunity Deficiency Syndrome. Acquired means you have got infected with it. Immune Deficiency means a weakness in the body’s system, that fight diseases. Syndrome means a group of health problems that make up a disease. People suffering from AIDS have an increased risk of cancer. Moreover, they also show symptoms like fever, swollen glands, chills, weakness and weight loss. Thus, the HIV virus progressively reduces the effectiveness of the immune system and leaves a person susceptible to many infections and turners. Hence, AIDS is better considered as a syndrome rather than a disease.
Explain give reasons:
(a) A balanced diet is necessary for maintaining a healthy body.
(b) The health of an organism depends upon the surrounding environmental conditions.
(a) A balanced diet is necessary for the growth and development of the body. A balanced diet provides raw materials and energy, in an appropriate amount, needed for the proper growth and functioning of the healthy body. It improves our immunity also. Lack of food in the form of a balanced diet makes us susceptible to diseases.
(b) Health is a state of being well enough to function well physically, mentally and socially. These conditions depend upon the surrounding environmental conditions, e.g. if there are un-hygienic conditions in the surrounding area, it is likely we might get infected or diseased. Similarly, a good social environment is needed for mental and social health.
