Steps of Nutrition in Humans
Ingestion:
- Ingestion is the process of taking food into the body through the mouth.
- It involves the intake of food and liquids that provide essential nutrients for the body.
Digestion:
- Digestion is the process of breaking down food into smaller molecules that can be absorbed by the body.
- It occurs in the digestive system through the action of enzymes and stomach acids.
- The nutrients are then extracted from the food particles.
Absorption:
- Absorption is the process of taking the digested food molecules into the bloodstream.
- It occurs mainly in the small intestine, where nutrients like carbohydrates, proteins, and fats are absorbed.
- These nutrients are then transported to different parts of the body for energy and growth.
Assimilation:
- Assimilation is the process of using the absorbed nutrients to build new cells and tissues or to provide energy for various metabolic processes.
- The body utilizes the nutrients from food to maintain its functions and repair damaged tissues.
Egestion:
- Egestion is the process of eliminating undigested food and waste products from the body.
- It involves the removal of indigestible materials through the process of defecation.
By following these main steps of nutrition - ingestion, digestion, absorption, assimilation, and egestion, the human body is able to obtain the necessary nutrients for growth, energy, and overall health.

The correct sequence of the main steps of nutrition in humans is:
- Ingestion: Intake of food
- Digestion: Breakdown of food into smaller molecules
- Absorption: Passage of digested food molecules into the bloodstream
- Assimilation: Utilization of absorbed nutrients by cells
- Egestion: Elimination of undigested waste
This order ensures that nutrients are extracted from food, absorbed, utilized by the body, and waste is removed efficiently.
