Protein is not a supplement, but three essential nutrients, protein, sugar and fat. Protein is the most important. It not only provides us with the ability, but more importantly, all our organs and tissues need to be synthesized by protein. If protein is absent from the diet, the synthesis of the body will be affected, leading to malnutrition. But many foods contain protein. Although some foods can't directly provide protein, such as grains, they can provide amino acids, or starch, which can be broken down into amino acids. And then synthesize protein.

Complement the benefits of protein: 1. It can increase the content of lean tissue, especially muscle tissue, which will have obvious benefits for improving physical fitness.

2. It can promote the normal function of physiological metabolism in vivo, because protein is an important part of enzymes and coenzymes in vivo. When protein is supplemented, the function of the enzyme will be smoother.

3, can improve the body's immunity, because many antibodies in the body need protein as raw material, when protein is fully supplemented, the ability to resist diseases will be relatively strong, so supplementing protein can improve the body's immunity.

In order to maintain the most basic physiological functions. The human body needs to ingest a lot of things, and protein is a very important part of it. Foods containing more protein mainly include:

1, dairy products. Protein contained in various dairy products of domestic animals belongs to animal protein. Animal protein is more nutritious than plant protein, because they contain different kinds and proportions of amino acids. Generally speaking, it is also more suitable for human needs.

2. Livestock meat. Such as cattle, sheep, pork and so on.

3. eggs. Such as eggs, duck eggs and quail eggs.

4. seafood Such as sea cucumber, fish, shrimp and crab.

5. Soybeans. Including soybeans, green beans and black beans, of which soybeans have the highest nutritional value.
