After fine classification, The seven major nutrients can be summarized:

(1) Protein

Protein is the basis of all life. It is continuously synthesized and decomposed in the body and is important for the formation, renewal and repair of tissues and cells.

Meat, eggs, milk, fish, and beans are the main nutrients that provide protein.

(2) Fat

The amount required may vary, but because the body cannot synthesize it or the amount of synthesis is insufficient, it must be taken from food. There are two types of vitamins: water-soluble (vitamins B, vitamin C) and fat-soluble (vitamins A, D, E, K, etc.). They are essential for the normal growth and development of the human body and the regulation of physiological functions. Vegetables and fruits are the main nutrients that provide vitamins.
