                        Nutrition


 



Nutrition is a critical part of health and development. Better nutrition is related to improved infant, child and maternal health, stronger immune systems, safer pregnancy and childbirth, lower risk of non-communicable diseases (such as diabetes and cardiovascular disease), and longevity.




Healthy children learn better. People with adequate nutrition are more productive and can create opportunities to gradually break the cycles of poverty and hunger.




Malnutrition, in every form, presents significant threats to human health. Today the world faces a double burden of malnutrition that includes both undernutrition and overweight, especially in low- and middle-income countries.



Why is nutrition important? 

Nutrition is essential for growth and development, health and wellbeing. Eating a healthy diet contributes to preventing future illness and improving quality and length of life. Your nutritional status is the state of your health as determined by what you eat. 



Essential nutrient requirements 





There are seven major classes of nutrients: 

1. Carbohydrates

2. Fats 

3. Fiber 

4. Minerals 

5. Protein 

6. Vitamins and 

7. Water.


  • Carbohydrates - 
  • our main source of energy.






  • Fats - 
  • one source of energy and important in relation to fat soluble vitamins.





  • Fiber (Roughage) - the fibrous indigestible portion of our diet essential to health of the digestive system.





  • Minerals - 
  • Those inorganic elements occurring in the body and which are critical to its normal functions.






  • Proteins - 
  • Essential to growth and repair of muscle and other body tissues.






  • Vitamins - 
  • Water and fat soluble vitamins play important roles in many chemical processes in the body.







  • Water - 
  • Essential to normal body function - as a vehicle for carrying other nutrients and because 60% of the human body is water.



Water is not technically a nutrient, but it is essential for the utilisation of nutrients. Nutrients perform various functions in our bodies, including energy provision and maintaining vital processes such as digestion, breathing, growth and development.
