Nowadays, many people pay attention to protein in their diet, how to distinguish the protein in food

Some plant-based foods are also rich in protein, such as rice, wheat and peas, which we often eat, but the protein in these plant-based foods will have a relatively low proportion of one or two amino acids. If you eat these foods alone, the efficiency of these amino acids to meet the needs of the human body will be relatively low, and they can be called "incomplete proteins". Among the common food proteins, collagen is called "inferior protein" because it "contains only 7 essential amino acids".

However, the proteins contained in different foods are combined, and the amino acids in them may complement each other, turning a low-quality protein into a high-quality protein.

When the pattern of protein amino acids contained in food is closer to the amino acid pattern of human protein, the easier it is for this protein to be absorbed and utilized by the body, and it is called high-quality protein. For example, proteins in eggs, milk, meat, fish. There are only 20 amino acids that make up natural proteins, and among these 20 amino acids, there are 8 amino acids that the body must obtain from food and cannot synthesize in the body, including isoleucine, leucine, tryptophan, threonine, phenylalanine, lysine, methionine (methionine), valine.

We call them essential amino acids. As long as these 8 essential amino acids are present, the body can make various other amino acids, which can sustain life and carry out growth and development. The number and type of essential amino acids contained in food protein has become the standard for measuring the quality of protein, and the more types and quantities of essential amino acids contained in food protein, the higher the nutritional value of food, and this protein is called high-quality protein.

Meat protein is the best protein in food, because meat protein is easier for the human body to digest and replenish nutrients than vegetable protein.

Compared with staple protein, (+ is a high-quality protein that is more beneficial to the human body.

Hello pro, high-quality protein is often found in foods that are not covered by the shed. 1.Lean meat, whether it is red meat such as pigs, cattle and sheep, or poultry meat such as chickens and ducks, lean meat is an important high-quality protein**.

2.Hands-on offal and animal offal are also rich in high-quality protein. 3.

Aquatic products, such as fish, shrimp, shellfish and crabs, are all high-quality protein foods. 4.Milk and milk bicha products.

5.Eggs and their products. 6.

Beans and their products, such as soybeans, black beans, peas and broad beans and other legumes, as well as soy milk, tofu and other related products.

We need to know that the basic unit of protein is amino acids, and there are more than 20 kinds of amino acids that make up proteins in living organisms, of which 8 kinds of amino acids cannot be synthesized by the human body and must be effectively supplied by food, which is called essential amino acids. Most foods contain 8 essential amino acids, but the nutritional value of protein varies depending on the proportion of amino acids in the food. Just like the eggs, milk, and soybeans that we often eat, these foods are rich in protein, and the ratio of amino acids is perfect for human needs.

In addition, the more amino acids in a protein that can be used by the body, the more it can meet the needs of the body. Only when the proportion of amino acids in protein meets the needs of the human body can it be fully utilized, and amino acids will not be wasted too much.

If the composition of the complex amino acids of the protein is close to the requirements of the human body, and the absorption and utilization efficiency of the human body is high, we can call this protein "high-quality protein" or "complete protein". Some vegetable foods are also rich in protein, like rice, wheat, and peas that we often eat, but the proportion of one or two amino acids in these vegetable foods is relatively low. If you eat these foods alone, these amino acids will be relatively inefficient in meeting human needs, which can be called "incomplete proteins".

Among the common food proteins, collagen is known as the "inferior protein" because it contains only 7 essential amino acids. Proteins are made up of amino acids. Some amino acids can be synthesized by the body, while others cannot.

There are eight essential amino acids that need to be obtained from food, so it's best to eat plenty of protein-containing foods.

Eggs are known to contain protein, milk contains protein, meat contains protein, and some vegetables and fruits also contain protein. These proteins are different in nature. Proteins contained in eggs, milk, meat, etc.

Collectively known as animal protein, while the protein in vegetables and fruits belongs to plant proteins. Do you know the difference between protein in various foods? How to properly supplement protein?

In fact, the biggest difference between the two is the composition of amino acids. Animal protein is higher in amino acids, higher quality, and easier to absorb. Does that mean animal protein is better than plant protein?

No. In plant protein, there is also a high-quality protein, called soy protein, ** in beans, its amino acid content and absorption rate are relatively high, close to plant protein.

When we choose foods to supplement protein in our daily lives, we must remember that we should not get them from just a certain food. Meat also has fat in addition to protein, and vegetable protein** is extensive but relatively simple. In general, eating only meat for protein may lead to obesity, eating too much cholesterol in eggs can lead to high cholesterol, and eating only a vegetarian diet can lead to immunoglobulin or other protein deficiencies, so do you know how to choose healthy foods?

Salmon from Hokkaido, cod and crab from Alaska, Australian lobster, white shellfish from New Zealand, and deep-sea fish are sold so high**, not only because of the shipping cost, but more importantly, they contain different nutrients, and there are no general foods, or the content is relatively low, so don't think that rich people just eat for the sake of eating.

The protein in food is divided into high-quality protein, and the protein that is easily absorbed by the human body is collectively called high-quality protein, such as eggs and milk, which have high protein content and are easily absorbed.

For example, eggs, milk and meat are called animal proteins, while the proteins of vegetables and fruits are called plant proteins.

Nowadays, many diets pay great attention to the quality of protein, if the quality of protein is not good, it will hurt our human body for a long time, we are rich in protein in eggs, especially native eggs.

There are many foods that contain protein. There are usually vegetable proteins and animal proteins. Foods high in plant protein are mainly soybeans and soy products. For example, foods such as tofu and soy milk are higher in plant protein, and walnuts and peanuts are also higher in plant protein.

<> foods with high animal protein content usually include animal meat, such as pork, beef, chicken, mutton, fish, shrimp, etc., which are high in animal protein. Chicken breast is high in protein and is easily absorbed and utilized by the body. It contains phospholipids, which play an important role in the growth and development of the human body.

Poultry meat, such as chickens, ducks, geese, quails, ostriches, etc. Eggs such as eggs, duck eggs, quail eggs and fish, shrimp, crab, etc. There are also soybeans, including soybeans, mung beans and black beans, among which the nutritional value of soybeans is other high-protein foods in addition to egg whites.

Friends can choose according to their preferences. Through the study of the knowledge in the article, we know that high-protein foods are not particularly nutritious, and only high-quality protein is the nutrition that our body needs. Because high-quality protein has a particularly complete range of essential amino acids, the absorption rate of the human body is very high.

The highest, it is the highest-quality protein in infant food**; Nuts and seeds are the essence of plants, generally rich in nutrients, high in protein, oil, minerals, and vitamins, and have a good effect on human growth and development, enhance physical fitness, and prevent diseases.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if there are any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, the like is the biggest help to me, thank you.

For example, eggs, milk, pork, chicken, mutton, beef, fish, shrimp, melon seeds, sesame seeds, walnuts, soybeans, mung beans, etc., these are high-quality proteins and do not grow fat.

There are many of them, such as our common tofu, but also chicken, mutton, fish and shrimp, eggs, milk and so on.

Eggs are a food with high quality protein and a very high content, as well as a very good energy addition.

It is tofu, and the tofu itself is made from soybeans, and the protein in it is very rich and the content is very high.
