INTRODUCTION:

“Nutrition is the process of taking food and converting it into energy and other important nutrients necessary for life.”

Even though our external body seems to be working till bedtime, the internal components inside the body continue to work for 24 hours. A lot of energy is required to work 24 hours. All the energy we get from the food that we consume. Food is important for physical processes, physical development, and physical repair and other life processes because it provides the energy needed for development, repair, and other life processes.

Details 

Nutrients are the substances that provide the energy and biomolecules needed to perform various functions of the body. All living organisms require nutrients for proper functioning and development.

Why is nutrition necessary for a living organism?

 A balanced diet reduces the risk of diseases and improves the overall health of an organism. It provides energy to cells to perform cellular activities.

Animal nutrition

Simple observation suggests that the animal kingdom is dependent on plants for food. Even meat-eaters, or carnivores, eat animals such as lions, and grazing animals and thus indirectly depend on the plant kingdom for their survival.

Human Nutrition

It is concerned with the provision of essential nutrients in food that are necessary to support human life and good health. Weak nutrition is a chronic problem often associated with poverty, food security or poor understanding of nutritional needs. Malnutrition and its consequences are major contributors to worldwide deaths, physical deformities and disabilities. Good nutrition is necessary for children physically and mentally and for normal human biological development.
