Protein is the main component of human muscles, skin, internal organs, hair, nails and blood; it is the basic material that constitutes body cells and is used for body growth and development, aging tissue renewal, damaged tissue repair, and various physiological functions. The birth, existence and death of life are all related to proteins. Therefore, protein is a living substance.

Examples of foods rich in protein: lean meat, milk, eggs, fish, soy products, nuts...

Water is also the main component of the human body.

There is water in human blood and muscles, accounting for 60%-70% of body weight. Water is an indispensable and important substance for the human body and the main component of cells. Various physiological activities of the human body cannot be separated from water. For example: various substances that nutrients are decomposed into after digestion need to be dissolved in water before they can be absorbed; most waste must be dissolved in water before they can be excreted from the body. On the one hand, water constantly enters the human body with food and drinks, and on the other hand, it continues to be excreted with waste. The water in the body always needs to maintain a certain balance. If the balance is lost, various physiological activities will be hindered, and even life threatening.
