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.

Minerals refer to nutrients such as iron, calcium, zinc, potassium, and sodium that are also indispensable components of the human body. For example: Calcium is the main component of bones (minerals also have the function of regulating human body activities. If you are deficient in zinc, you will not be able to grow taller.)

Water is also the main component of the human body. There is water in human blood and muscles.

Starch and fat are energy materials for the human body. All human activities, such as running, walking, writing, thinking about problems, etc., consume energy, and all of this energy comes from fat and starch. Therefore, if a person lacks fat and starch, it is like a car that cannot run without gasoline.
