PROBLEMS IN NUTRITION :


Problems related to nutrition are grouped as malnutrition. It often refers to under-nutrition resulting from inadequate consumption, poor absorption, or excessive loss of nutrients. Malnutrition also includes over-nutrition, resulting from overeating or excessive intake of specific nutrients.
Sometime, malnourished people either do not have enough calories in their food, or eat a diet that lacks protein, vitamins, or trace minerals. Malnutrition weakens the immune system, impairs physical and mental health, slows thinking, stunts growth and affects fetal development. Common Forms of malnutrition include protein-energy malnutrition, mineral deficiency disease, and over-intake of nutrients.
A-Protein Energy Nutrition:
 Protein- energy malnutrition means inadequate availability or absorption of energy and protein in body. It is the leading cause of death in children in developing countries. It may lead to diseases such as Kwashiorkor and Marasmus.

 FAMINE-THE MAJOR CAUSE OF MALNUTRITION:

                                                 Famine means lack of enough food to feed all people living in area. The most terrible famines of the twentieth century are Ethiopian famine and North Korean famine. The major causes of famine are unequal distribution of food, drought flooding or increasing population. Some people life happy life with good health and wealth but some of people are in very bad condition they have no health and wealth this is because of un equality in peoples. Some of us not want other live happy and healthy life because of this we not progress and we go down and cause some several disease.
1.       Unequal distribution of food:
The achievements in science have enable human beings to produce better food in terms of quality and quality. Today the agricultural practices produce more than enough food that can be supplied to everyone on the earth. But due to political and administrative problems food is not equally distributed to different regions of world. The result is that there is always surplus food in countries like America , Uk, and Canada etc and at same time people have nothing to eat in different countries like Ethiopia , Somalia etc .
2.       Drought :
               A drought is a period of time when there is not enough water to support agricultural and human needs. Drought is usually due to a long period of below-normal rainfall. Droughts decrease or even stop the crop yields and it results in famine.
3.       Flooding :
              Its occurs due to more than normal rainfall or due to weak water distribution system. Rivers and canals overflow their banks and destroy the soil quality of agricultural lands. It becomes impossible to grow crops immediately after flooding. In this way, flooding may be a reason for short-term famine.
4.       Increasing population:

                          In spite of global increase in food production, millions of human beings are undernourished. In the over-populated regions of world, large populations overuse natural resources to grow maximum food in order to meet the problems of food shortage.  It leads to dry and infertile lands and depletion of resources. In such situations crops can no longer be grown and famines result.
