Protein is the main material that makes up the human body. Without protein, there would be no human life, just like there would be no houses without bricks, cement, and sand.

Inorganic salts: refers to nutrients such as calcium, iron, zinc, phosphorus, and sodium. They are also important materials that constitute human tissues. For example, calcium and phosphorus are important parts of bones and teeth; without zinc, you cannot grow taller.

Water is also the main substance that makes up the human body. There is a lot of water in human blood and muscles.

Carbohydrates and fats are energy materials for the human body

All human activities, such as running, walking, writing, thinking about problems, etc., consume energy. This energy mainly comes from sugar; fat is stored in the body as a backup energy substance. Therefore, if a person lacks sugar and fat, it is like a car that cannot run without gasoline.

Vitamins are also indispensable nutrients for maintaining human life activities. The lack of vitamins will affect the normal growth and development of the human body, and severe deficiencies can also cause diseases. For example: lack of vitamin C can cause bleeding gums, lack of vitamin D, and poor bone development.
