Nutrition



                                                   Nutrition
      Every individual needs nutrients in order to remain healthy. Nutrients supply the necessary needs of the body for proper functioning and normal growth and development. We get these nutrients from food. so, the diet of an individual has to be balanced in order to get all the nutrients required by the body. Proper nutrition saves us from physical and mental deformities. If the body lacks any of the food constituents, such as proteins, carbohydrates vitamins, fats and minerals it causes malnutrition. If the proportion of the constituents of food is disturbed and the diet fails to meet the needs of the body, then the condition is known as malnutrition.

Causes of malnutrition                                     
Under- nourishment and malnutrition may be used by the following factors:
-          the food constituents are not present in required proportion as to meet the needs of the body.
-          Children are not fed properly and timely.
-          Lack of balanced diet during pregnancy.
-          Prevalence of parasitic and infectious diseases like worm, diarrhoea, dysentery.
-          Physical and environmental factors, such as lack of sunshine, fresh air, sound sleep, proper exercise, may lead to malnutrition.
-          Food habits, customs, beliefs, tradition, and attitudes play an important role in causing malnutrition.
-          General illiteracy and ignorance regarding the ways and means of food preservation, use and management.
-          Chronic alcoholism.
-          Poverty.
-          Lack of personal hygiene and care.
          Malnutrition is a human-made disease, which begins quite commonly in the womb and ends in the grave.

Effects of malnutrition
Each food constituent has its own function and role. Similarly, the deficiency of each food element has its own effects. Generally, malnutrition may have the following major effects on a person’s health:
a)       Physical effect: one of major functions of food is to help in the proper growth and development of the body. It influences physical fitness and organic development. As for example, lack of calcium leads to rickets which is characterised by stunted growth of bone, calcification of bone, whereas lack of  protein leads to Kwashiorkor and marasmus which is characterised by loss of weight, retardation of motor development, retardation of growth. Similarly, malnutrition in early stage of life may lead to various physical effects such as deformation of bones, ill-formed teeth, anaemia, blindness and goitre.
     b)      Mental effects: malnutrition also effects the mental development of a child. The mind                 
becomes slow and doll. It leads to loss of memory, irritation and uncontrolled emotion.
     c)      Social effects:  malnutrition leads to physical and mental deficiency, which ultimately
leads to mal-adjustment of social life. Individuals who are not physically fit, organically
sound and mentally balanced can never fulfil their daily needs resulting in frustration, tension
and other social disturbances. These people cannot maintain their family life, and cannot
participate in social activities. Thus, malnutrition is a social disease which affects directly on the progress and achievement of a citizen and the nation.

Malnutrition diseases

                Marasmus: a nutritional disorder due to the deficiency of protein and calories is known as     
‘Marasmus’. It is seen most commonly in weaned infants and children below faive years.
A child with this disease is characterised by emaciated look, irritation, loss of appetite, dehydration, incessant diarrhoea, etc. the limbs are thin but the stomach is swollen and the
body looks shrunken.
