What is nutrition?

Nutrition means the nourishment which our body requires for growth and development. It is basically a process of obtaining or providing food which is necessary for promoting health and growth. It is a combination of different processes which includes food consumption, producing energy out of it and using the energy for growth, development, health, metabolism, and repairing of the body. The nutrition has the following stages like ingestion, transport, digestion absorption, assimilation, and excretion.


Nutrition plays a critical part in one’s health and development. Better nutrition shows better health and is also helpful in keeping you away from diseases and lowers the risk of infectious or communicable diseases. People with adequate and better nutrition are more productive, active and energetic. While on the other hand, people who lack nutrition are more prone to cause diseases. They feel lethargic and less energetic in comparison to others which is why they are less productive majorly in all important domains of life.
