Introduction
Nutrition is an important part of maintaining a healthy lifestyle. It is essential to understand the five stages of nutrition so that you can make decisions on how to best meet your nutritional needs. The five stages of nutrition include: ingestion, digestion, absorption, metabolism, and elimination.
Ingestion
Ingestion is the process of taking in food and drink. During this stage, the body breaks down the food and drink into smaller molecules that can be absorbed by the body. This process happens in the mouth, and it is the first step in the digestion process.
Digestion
Digestion is the breakdown of food and drink into smaller molecules that can be absorbed by the body. This process happens in the stomach and intestines. During digestion, enzymes in the stomach and intestines break down the food and drink into small particles, which are then absorbed into the bloodstream.
Absorption
Absorption is the process by which nutrients are taken from the digestive tract and transported to the cells of the body. During this process, the nutrients are converted into molecules that can be used by the body.
Metabolism
Metabolism is the process that converts the nutrients into energy that can be used by the cells of the body. During this process, the nutrients are converted into molecules that are used by the body to carry out its functions.
Elimination
Elimination is the process by which the body removes waste from the body. During this process, wastes are removed from the body through the excretory system. This process helps to maintain the body's balance and keep it functioning properly.
