What foods are animal proteins? What are the foods that are high in animal protein

Animal proteins include meat, eggs, and milk from poultry, livestock, fish, and insects.

Animal protein is relatively consistent with the nutritional structure of human beings, and the type and structure of its protein are closer to the protein structure and quantity of the human body, and generally contain 8 kinds of amino acids necessary for the human body (especially egg products and dairy products), so the nutritional value of animal protein is higher than that of plant protein.

Animal protein**

The proteins of pork, beef, mutton, poultry, fish, etc., are close to the content of various amino acids required by the human body. Shellfish protein is also comparable to meat, poultry, and fish. They are both good dietary proteins**, with a protein content of 10-20%.

Milk and eggs have a lower protein content, the former being 11-14% and the latter being 11-14%.

However, they are highly nutritious, and their essential amino acid content is similar to the pattern of essential amino acid requirements. Certain meat, dairy and egg products such as pork floss, milk powder and cheese, as well as egg powder and protein tablets have high protein content. Breast-milk formula is further formulated according to the composition of breast milk to meet the needs of infants and young children, and has higher nutritional value.

Foods containing animal protein mainly include animal meat, fish and shrimp, eggs and milk.

1.Animal meat: Of all known animal meats, such as:

Pork, mutton, chicken, rabbit and goose meat, etc., contain very rich protein, and are very conducive to the digestion and absorption of the human body, which contains a complete range of amino acids, which is very suitable for people with protein deficiency.

2.Fish and shrimp: Fish and shrimp meat is generally composed of chemical components such as water, protein, fat, carbohydrates and minerals.

The muscle fibers are thin and short, the tissues are soft and delicate, easy to be digested and absorbed by the human body, and the protein value is second only to eggs, especially suitable for children and the elderly. For example, grass carp, sea bass, eel, river shrimp, sea shrimp, etc.

3.Eggs: Various egg foods in life are often called high-protein foods, such as eggs, duck eggs, goose eggs, etc., so you can eat more eggs if you urgently need to supplement protein.

The role of animal protein

1. It constitutes an important material basis for the body and life.

Proteins have catalytic action (enzymes), scaffold action (collagen), immune action (immunoglobulin); Involved in the regulation of physiological functions (hormones), the transport of oxygen (hemoglobin), muscle contraction (actomyosin), the production of genetic material (nucleoproteins), the maintenance of osmotic pressure of blood vessels in the body (plasma proteins).

2. Construct and repair the renewal organization.

Protein is always in a dynamic equilibrium of continuous decomposition and synthesis, and the normal human body contains about 16% 19% protein, and about 3% of the body's protein is renewed every day.

3. Provide energy.

Each gram of protein is oxidized in the body for energy, and about 10% of the energy required by the human body every day comes from protein.

4. Supplement nutrition.

Egg whites are rich in protein, vitamin A, vitamin B, calcium, phosphorus, iron, and other nutrients needed to maintain normal metabolism and prevent malnutrition and other symptoms.

Acorn protein foods include meat, eggs, and milk. Animal proteins are mainly used in fish, shrimp, poultry, meat, eggs and milk. Generally speaking, most animal proteins are high-quality proteins, because animal proteins contain a large amount of amino acids necessary for the human body, and have a high absorption rate in the human body and have high nutritional value.

Features:Animal protein refers to poultry and poultry food, which is one of the important foods for human beings because of its rich nutrition, delicious taste and wide consumption. Studies have proved that in people who eat cereals, there is a tendency to not easily absorb animal protein, such as eggs, nearly half of the protein can not be absorbed and utilized by the human body. Animal protein contains a lot of fat, which is easy to cause obesity and increase the source of disease to people.

Animal experiments have shown that animals that eat animal protein develop and grow quickly, but have a short lifespan. Whereas, animals that eat plant protein have slow development but have a long lifespan and good endurance. If an appropriate proportion of soybean selenoprotein is added to the milk next to the chopping filial piety, the complementary role of protein can be fully exerted, so that the human body can obtain a balanced and appropriate amount of amino acids, and greatly improve the nutritional and physiological value of milk.

Animal protein foods.

Poultry eggs, eggs, duck eggs.

Meat, pork, beef, lamb.

Aquatic products, fish, shrimp, crab, dairy, milk, goat's milk.

It's the protein of animals.

1.Dairy foods and dairy products.

Milk such as cow's milk, goat's milk, mare's milk, etc., all belong to the milk of livestock, which contains a lot of protein, among which cow's milk contains the most abundant protein content. Milk can not only help us replenish sufficient protein, but also rich in calcium, and regular consumption can help us effectively prevent calcium deficiency.

It can be said that the calcium content of skimmed milk powder is the highest, and the oil content is almost none, so the milk made of skimmed milk powder is the best protein and calcium for adults to maintain a slim figure.

2.Meat food.

There is a wide range of livestock meat, such as cattle, sheep, pigs, dogs, chickens, ducks, geese, quails, ostriches, etc., and these meat foods belong to livestock meat. This kind of meat contains amino acids needed by the human body, and the types of amino acids are most consistent with the amino acids in animal protein, so the nutritional value of animal protein is higher than that of plant protein.

Moreover, among all animal proteins, because the protein of milk and eggs is easy to digest, has a complete range of amino acids, and is not easy to cause gout attacks, it can be said that its nutritional value is the best among all protein foods.

3.Eggs.

When it comes to foods with high protein content, eggs are the best among them, whether they are eggs, duck eggs or quail eggs, where the yolk contains slightly more protein than the egg white. Although egg yolks are very high in protein, one egg yolk can contain up to 300 mg of cholesterol, so even people without heart disease should not eat egg yolks. The cholesterol content of the egg white is 0, the egg yolk contains a lot of oil, and we can't see the fat in the egg yolk, but if you bake the egg yolk in the microwave, you will find that a lot of oil can flow out, and the oil of the egg yolk can also be seen in the yolk of the salted egg.

Studies have found that egg yolks contain 6 times more calories than egg whites, so egg yolks are also considered high-calorie foods. Therefore, many people take eggs as the best choice, which can not only provide nutrition, but also help us achieve the best effect.

4.Soybeans and soy products.

Plant-based proteins are also foods with high protein content, such as soybeans, large green beans and black beans, but soybeans have the highest nutritional value. The best of the plant-based proteins is soy protein, and it is also very easy for the body to digest and absorb, so soy protein has always been the main protein for vegetarians**.

1. High-protein foods, one is milk, meat, poultry, eggs, fish, shrimp and other animal proteins; The other category is soybean soybeans, large green beans and black beans and other legumes, sesame seeds, melon seeds, walnuts, almonds, pine nuts and other dried fruits of vegetable protein. Because the types and proportions of amino acids contained in animal protein are more in line with human needs, animal protein has higher nutritional value than plant protein.

2. Beans, peanuts, meat, milk, eggs, fish and shrimp are higher in food, while cereals are less and less in vegetables and fruits. The body's need for protein depends not only on the amount of protein, but also on the type and proportion of essential amino acids contained in the protein. Because the types and proportions of amino acids contained in animal protein are more in line with human needs, animal protein has higher nutritional value than plant protein.

3. In plant foods, the protein contained in rice and flour lacks lysine, and the legume protein lacks methionine and cystine, so eating mixed foods has complementary functions and improves the utilization rate of mixed proteins. Although the protein content in human milk, cow's milk, and eggs is low, the amount of essential amino acids they contain is basically consistent with that of the human body, so the nutritional value is higher.
