What functions does protein have on the human body?

In order for the body to work properly, people need to consume some protein every day. Many people know that protein has many benefits to the body, and protein exists in many foods, such as eggs, lean meat, milk, etc. There are even some people who always one-sidedly believe that the more protein you eat, the better it is for the body. Let me give you a detailed introduction to the effects of protein on the human body!

Protein is composed of amino acids and is another important energy source, providing 4 calories per gram. But the more important role of protein is growth and metabolism. Excessive protein intake will increase the burden on the kidneys. Therefore, protein intake should achieve a balance between supply and demand based on nutritional status and growth and development requirements.

Generally, the calories generated by protein intake should account for about 20% of total calories.

Physiological effects of protein: Ø Growth and development, metabolism are the main effects. It also provides calories, 4 kilocalories per gram, and increases the burden on the kidneys.

Protein is the material basis of all life, not only because protein is the basic component of the body's tissues and organs, but more importantly, protein itself is constantly synthesized and decomposed. This contradictory and unified process of synthesis and decomposition promotes life activities, regulates the body's normal physiological functions, ensures the body's growth, development, reproduction, heredity, and repairs damaged tissues. According to modern biological views, proteins and nucleic acids are the main material basis of life.

Protein Types:

Animal protein: It is the main source of protein, such as meat and eggs. While these foods provide protein, they also make us consume saturated fat, cholesterol and other ingredients that are harmful to the body. Therefore, it is best to choose lean meat, fish, skinless chicken and egg white, which are called "high-quality proteins".

Plant protein: It is another source of protein, mainly found in bean foods. Plant protein is low in saturated fat and cholesterol, and contains a large amount of dietary fiber. It is inexpensive and suitable for diabetic patients.

As can be seen from the above, protein plays a major role in the growth, development and metabolism of the human body and is the material basis of life. However, if too much protein is consumed every day, it will increase the burden on the kidneys. Therefore, it is best to control the protein intake appropriately according to personal nutritional needs. It is not the case that the more you eat, the better.
