Humans consume food to obtain energy. After consuming food, they digest it. Following digestion, absorption takes place. Then assimilation occurs, and finally, excretion happens. Through this process, the body receives essential nutrients, which support human growth and development and provide energy for daily needs.

Our health depends on certain essential elements, which enable energy production, cell formation, and the functioning of various biological processes. These essential elements are as follows:
- Carbohydrates
- Fats
- Amino Acids
- Proteins
- Vitamins
- Mineral Salts
- Water
Carbohydrates and Fats – In the human nutrition process, carbohydrates and fats provide energy. This energy helps in carrying out daily tasks and other necessary functions.
Amino Acids and Proteins – These are essential for building and repairing body cells in the process of human nutrition.
Vitamins and Minerals – These play a vital role in carrying out metabolic processes in the nutrition cycle.
Water – Water is an element that is essential for all bodily functions. Without water, the process of nutrition or life itself cannot be sustained. In other words, water is life.
