What food contains proteins. Interaction with essential elements. All these rules are valid under certain conditions.

What foods contain protein is an urgent issue when getting rid of extra pounds and when gaining muscle mass. The use of the right protein foods will help give the figure the necessary harmony, and the body with a sporty relief.

The human body all the time needs to restore the tissues of muscles and internal organs, the cells of which are aging, injured by foreign microorganisms or as a result of physical exertion, shock, falls, and therefore need to be replaced.

An important role in this is played by proteins and the amino acids they contain: cystine, cysteine ​​and methionine, which are involved in the synthesis of collagen, a trace element that maintains healthy skin, nails and hair.

Protein also has an effect on the hormonal background, normalizing insulin levels and preventing metabolic disorders, excess weight, diabetes and early aging.

Note! Protein is quite often confused with protein, considering them synonyms; but in fact this is not entirely true: its meaning implies one of the types of protein, and not the protein itself.

In general, there are two types of protein: simple and complex. Complex proteins form the following solid structures in epithelial (outer), bone and connective tissues, ensuring their density, elasticity and low damage:

• collagen- protein of the skin, bones, cartilage, joints (food products with it: turkey, beef, gelatin; salmon, chum salmon, pink salmon, fish oil, salmon; seafood: kelp and other algae);
• keratin- makes up the horny covering - nails, hair (formed by combining lean meat with sour fruits (for example, lemon); found in milk, fish);
• elastin- provides elasticity of the walls of blood vessels, tendons (unlike collagen, it is present mainly in dairy and marine products, in plant foods: buckwheat, oatmeal and millet porridge, apricots, carrots, pumpkin, avocados, cabbage, sea buckthorn, gooseberries, currants, walnuts and almonds, grape seeds).

A simple plant protein is gluten. They are rich in wheat products, gluten is the basis of their gluten. This protein is characterized not only by a positive effect on the body, quite often it causes allergies in adults and children.

What foods contain protein

In a balanced diet, it is necessary to obtain proteins from all types of foods rich in them with a high percentage of digestibility, namely:

• meat: all dietary meats (90%), eggs (97 - 100%);
• fish (90%);
• dairy (95 - 100%);
• vegetable: legumes and cereals (70 - 80%).

It's important to know! In a separate diet, foods that contain large amounts of protein should be consumed separately from each other, since different types of protein require the simultaneous production of various enzymes by the digestive glands.

Not all proteins are digested at the same rate, and some can linger in the digestive system, causing fermentation and indigestion.

Animal products as the main source of protein

According to the results of studies conducted by nutritionists, a person needs to eat from 100 to 200 g of meat per day, 100-400 g of cottage cheese and 2-3 eggs per day to cover the daily protein requirement. Also, according to WHO recommendations, you need to eat at least 200-300 g of freshly cooked fish per week - then the body will not feel a lack of amino acids that cannot be synthesized by it.

What animal products contain protein (from 15 to 30 or more g of protein per 100 g):

• Soy meat (35 g).
• Hard cheeses (24–30 g).
• Tuna (20 - 25 g).
• Rabbit meat (21 g).
• Beef (20 g).
• Low-fat cottage cheese (15–18 g).

9 to 15 g of protein per 100 g:

• Fatty cottage cheese (14 g).
• Eggs (12.7 g).

Nuts and seeds containing protein

Nuts and seeds include a complex of useful substances: potassium iodide, magnesium, zinc, copper, iron, potassium, essential poly- and monounsaturated fats, as well as omega fats, which are necessary to strengthen the immune system, metabolism, good memory and improve mental abilities.

Interesting fact! The properties of walnut fruits were noticed by the ancient Assyrians: they were forbidden to be given as food to slaves so that they would not develop extraordinary mental abilities.

Nuts and seeds are no less valuable in the diet of vegetarians, some types of nuts contain 2 times more proteins than in meat:

Top 10 Highest Protein Foods

It is always important for athletes and those who are on a protein diet for weight loss to know which foods contain the required amount of the substance in question for a daily diet. Below is a table listing the top leaders.

It's important to know! An excess of protein can lead to diseases of the kidneys, liver, joint pain, gastrointestinal disorders, such as flatulence, constipation, microflora disturbance due to fermentation in the intestines caused by residual proteins not digested by the body.

The lack of proteins can provoke muscle atrophy, premature skin aging, rashes, swelling, reduced resistance to infections, osteochondrosis, rickets, dystrophy.

Protein is a useful element for the body, in order to avoid a deficiency of this component, it is necessary to eat foods rich in it. However, you should not get carried away only with protein products, since their overabundance leads to negative consequences for the body.

Watch an interesting and useful video about which foods contain protein:

Here are our top 5 high protein foods:

Each product contains three important components. These are proteins, fats and carbohydrates. A person who thinks about his health should allocate a special place in his diet for the most useful of them - proteins. By eating foods with the highest protein content, you can improve your health, make your appearance more attractive, and even lose weight. This nutrient is the basis of life and the building material of the body.

Why is it important to eat high protein foods?

Enriching your diet with protein-rich foods is important for a number of reasons. One of them is the fact that protein (or protein, as it is also called) is involved in the structure of muscle tissue. It is for this reason that high-protein nutrition is recommended for professional athletes, fitness enthusiasts, and children.

Supporters of a healthy lifestyle and quality nutrition should be aware that their daily protein requirement is calculated based on weight. For every kilogram of human weight per day, there should be 2 grams of protein. That is, if a person weighs 70 kilograms, then a day he should include about 140 grams of protein in his food. Studying the list of foods that contain a lot of proteins, you can see that some of them are quite high in calories, while others, on the contrary, provide very little energy. This fact should also be taken into account when choosing the right diet.

On the other hand, according to experts, the daily requirement for proteins should generally be 40% of the total food intake. This is one of the keys to good nutrition.

Protein is very important to eat for physically active people, because it is able to restore the expended energy of a person. When an excess of protein occurs in the body, it does not turn into fat and does not lead to the appearance of extra pounds, unlike carbohydrate foods.

Before the main table of proteins in foods is described, it is worth paying attention to the negative qualities of protein foods.

Harm from protein foods

As you know, fats, carbohydrates, and proteins can harm the human body if consumed in excess. Therefore, harm to the body is possible only in the case of the formation of excess protein in the body. This is due to the fact that only the necessary need for proteins is easily absorbed by the body. The rest needs to be recycled. This process requires the participation of calcium. If it is not enough in the body, it will be drawn from the bones. Constantly exceeding the norm of protein can lead to a number of unpleasant diseases. For example, osteoporosis.

It is very important to study the composition of proteins in foods for another reason. Their excess leads to unnecessary stress on the kidneys. When eating food with a high content of animal protein, it is worth remembering that cholesterol enters the body along with it, which adversely affects the human body.

In order to avoid all of the above side effects, you need to add proteins to the diet, depending on the needs of your body. It is worth paying attention to the total calorie content of a product containing a lot of protein. It is found in large quantities in meat products, eggs, cheese and cottage cheese, cereals and some other products.

Both animal and vegetable protein are very important for the body. The list of products containing it should start from the first. Animal protein is also called a complete protein. This is due to the content of a complete amino acid complex in it.

Products containing protein in large quantities of animal origin are meat products. Their list starts with chicken and turkey. Every 100 grams of chicken or turkey meat contains about 20 grams of protein. From these products, it is easily digestible. In addition, these two types of meat are considered dietary due to their low calorie content. They must be added to a balanced diet.

Products with the highest protein content can also include another type of meat - beef. There are about 25 grams of protein per 100 grams of beef meat. But it is much more difficult for the body to digest. That is why it is better to eat it boiled.

A large amount of protein is found in beef, pork or lamb liver. About 18 grams per 100 grams of product. It is recommended to use it in a stew.

There are other foods that contain large amounts of animal proteins. It's fish and seafood. It is a storehouse of protein and other useful trace elements. Any fish is easily digested by the body, which absorbs all the nutrients. Supporters of a healthy diet should definitely include this type of protein-containing food in their diet.

Protein in cereals

Protein is found in a number of cereals. In addition, each of them is useful for the good functioning of the digestive system. Protein in foods, that is, in cereals in this case, is contained in different quantities. But it is absorbed equally well.

Buckwheat groats contain 12% vegetable proteins. It is very beneficial for the body. Oatmeal is no less useful and comes second on the list in terms of protein content. It has 11 grams of protein per 100 grams of cereal. Wheat groats are on the same position as oatmeal. It also contains 11 grams of protein.

Completing the list of cereals rich in protein is rice and corn. They have 7-8% protein content.

Porridges are very useful for the human body, but when adding them to the diet, it is worth remembering that carbohydrates are the main part of them.

Protein in eggs

When it comes to protein-containing products, the question of how much protein is in one egg is considered natural.

Chicken eggs come in a variety of sizes and weights, but on average two eggs make up 100 grams of total weight. Accordingly, one egg can contain about 50 grams of mass. 100 grams of such a product accounts for 17% of proteins. This means that one egg contains about 8.5 grams of protein.

It is from this product that protein is absorbed best. Its calorie content is quite low. Chicken eggs also contain many useful acids that are involved in important metabolic processes in the human body.

Protein in cheese, cottage cheese and milk

Foods with the highest protein content are also cheese and cottage cheese. Each of them is worth considering separately.

Cottage cheese contains about 14% protein. It is very beneficial for the body. It is high in calcium, which in some cases may be required for protein processing. Depending on the fat content of the cottage cheese and the protein content in it may vary slightly. It is recommended to add fat-free cottage cheese to the diet.

Hard cheese is made from cottage cheese. But the protein content in it is twice as much. So, on average, 100 grams of cheese contains about 30 grams of protein. It is worth noting that hard cheese is very high in calories, and you need to add it to the diet in small quantities.

The table of proteins in products contains information that milk consists of only 5% of them, despite the fact that cottage cheese and cheese are its derivatives.

Other High Protein Foods

There are other favorites in terms of protein content. What foods are high in protein? First of all, it is soy, lentils and Brussels sprouts.

Knowing how much protein is in one egg, 100 grams of meat, cottage cheese, cheese, various cereals, you can easily create a balanced diet that will help the body effectively build muscle tissue, lose extra pounds and restore energy after exercise.

Proteins are chemical compounds, without which human life is impossible, since they produce energy, actively participate in transport, metabolism and many important processes that occur in the human body. What foods have a lot of protein, how much a person needs and why, we will analyze in detail in this article.

Basic functions of proteins

• plastic, supplies the body with plastic material, therefore all cells, organic tissues, enzymes and many hormones are characterized by the composition of the protein;
• hormonal function regulates the system of biochemical reactions of the human body;
• the catalytic function delivers energy to cells, since the enzymes consisting of this substance are involved in the breakdown of food into simple components;
• the transport function is responsible for transporting oxygen from the lungs to the organs and tissues of the body;
• the protective function consists in the work of proteins of the immune system, which are called antibodies and guard the health of the body, giving it the strength to fight bacteria, viruses and other harmful substances;
• the contractile function is in the presence of special proteins myosin and actin, which provide complex work and coordinated muscle contraction;
• the regulatory function strengthens the nerves and speeds up the production of conditioned reflexes.

The lack of this substance in food can provoke a number of pathological changes, such as growth and development retardation, a decrease in the body's defenses, and a deficiency of digestive enzymes. That is why a person should eat foods containing proteins.

In turn, healthy food can improve health, make the appearance attractive and even help in losing weight. Protein in the nutrition program is relevant for people who lead a physically active lifestyle, as it quickly replenishes the expended energy of a person.

What foods are high in protein: tables and description

Protein is found in products of plant and animal origin, and naturally, the second group is the leader in its content.

Animal Products

Meat

Meat is well absorbed by the body because it contains protein and a full range of amino acids. A huge advantage over other products is a large selection of cooking methods and ease of use in large volumes. This is important if you need to quickly replenish the protein resources in the body.

poultry meat contains protein, which has reduced caloric values ​​and is easily digested compared to other types of meat.

Beef characterized by the most complete proteins, since the meat is rich in amino acids, vitamins, iron. For greater usefulness of the product, it is advised to stew or boil the product.

in pork contains a large amount of proteins. The dry weight of lean pork contains the nutrient, which is why it is considered one of the main dietary sources of protein.

Table of meat products that are high in protein

List of protein products from fish and seafood

Fish recipes are presented with dietary, healthy and delicious dishes. By the presence of proteins, fish is similar to meat. Its largest amount is in lobster, mullet, anchovies, tuna, salmon. Also in the fish there are many different amino acids and minerals such as: iodine, potassium, phosphorus, vitamins A, B, E, D.

Its main advantage is the minimum composition of structural fibers, represented by collagen. The meat of boiled fish is tender and soft, and the protein is perfectly absorbed by the body. Only you should refrain from eating smoked meats, both fish and meat.

Eggs

Bird eggs are dietary foods that are high in protein. The yolk contains a significant amount of proteins, fat-soluble vitamins, minerals, and, of course, pepsin. Egg protein contains substances necessary for building muscle, nervous and skeletal tissue.

Which dairy products contain the most protein

In the composition of dairy products, in addition to minerals, there is an easily digestible protein.

Casein

Cow's milk, kefir, cottage cheese - suppliers of protein such as casein. It evenly distributes amino acids in the blood, which is why the feeling of satiety persists for a long period of time. This group of products should be consumed by people who restrict themselves in nutrition for a long time in order to lose weight.

Albumin and globulin

Serum, especially its concentrate, is rich in such useful proteins as albumin and globulin. They will help lower blood cholesterol, increase the metabolic rate, which will contribute to the rapid breakdown of fats. They are extremely similar in composition of amino acids to the proteins of human muscle tissue. They are also considered sources of essential amino acids. Whey proteins also have a beneficial effect on the nervous system, as they reduce the rate of the stress hormone cortisol in the body.

Cheese- this is a protein-rich product, if only it is prepared from natural ingredients in accordance with all the rules (not a cheese product!). For weight loss, when choosing cheese, it is necessary to give preference to less high-calorie varieties, for example, cheese. If enhanced nutrition is required to gain body weight, then fatty high-calorie cheeses are introduced into the diet.

What dairy products have a lot of protein: table

Protein in plant foods

Vegetable protein helps to strengthen the immune system, prevent colds, saturate the body with fiber, restore natural microflora, improve metabolism, help normalize digestion, protect against obesity, energize, add strength and improve skin, hair and nails.

Plant protein is found in legumes, nuts, seeds, dried fruits, raw vegetables and fruits. What plant foods have a lot of protein - in detail.

Protein in legumes

Modern trends towards wholesome food consumption consist of a huge group of leguminous plants. They are varied and include significant amounts of protein, plant fiber, B vitamins, and minerals.

Legumes are affordable and can be used to make a variety of delicious dishes, making them popular among vegetarians. Legumes are also useful for people during fasting or when following a plant-based diet to cleanse the body, as they can satisfy hunger and provide the body with protein needs.

Nuts are the real leaders among plant foods that contain a lot of protein.

Peanut relieve hunger for a long time. This nut is best excluded from the diet for people who have problems with the stomach and intestines, kidney disease, and are also prone to allergic reactions.

Cashew nuts, in addition to protein, it also contains a lot of carbohydrates, so you should not get carried away with it. Mostly consumed fried.

pistachios consist of fiber, antioxidants, which are the first helpers for the skin, slow down the aging process, thereby prolonging youth and setting the body for longevity. Pistachios are recommended for those who are exposed to significant physical exertion and people prone to thinness.

Almond contains a sufficient amount of protein, but has almost no carbohydrates, therefore it helps to remove “bad” cholesterol from the body, normalizes blood sugar levels. Significantly satisfy hunger due to high calorie content.

Advantage hazelnuts is a combination of protein and vitamin E, which has a positive effect on muscle tissue. When choosing hazelnuts, you should be aware that peeled nuts lose their valuable properties during storage, so unpeeled fruits should be preferred.

walnut nuts are very popular and sought-after fruits. There are many different recipes using this nut. Lowers blood pressure, calms and promotes brain activity.

Fruits and vegetables

Fruits and vegetables contain a small amount of protein, so it is not advisable to consider them as a source of protein. Consist of fiber, vitamins and carbohydrates that the body needs for normal functioning.

Protein products for weight loss

When protein is consumed, the body is enriched with proteins and there is a shortage of such an energy source as carbohydrate. When losing weight, the body has to burn what is more available to it, namely reserves of fat. In this case, there is a change in metabolism. In addition, the protein that comes with food needs significant energy costs for splitting.

The list of products that are advisable to add to a weight loss nutrition program includes:

• milk
• low-fat cottage cheese
• soy cheese
• lean meat
• buckwheat
• beans and nuts.

Protein-rich foods are essential components of a healthy diet. When developing a menu, the presence of all food groups in which protein is located should be taken into account to ensure the supply of all types of amino acids. It is also necessary to control the protein content - its deficiency, as well as an excess, can provoke negative consequences for a person.

Proteins, along with fats and carbohydrates, form the basis of human nutrition. Everything that enters the body in the form of food has a specific function.

Protein-rich foods are very important for growth and strengthening, as they are the building material for tissues and cells. How to build your diet so that the body does not lack them? Which Consider in this article.

Importance

In Greek, the word "protein" sounds like "protein". If we consider the literal translation, it turns out that this word means "the one that comes first." At least on the basis of this, conclusions can be drawn.

The need of the human body for food, where there are a lot of proteins, is great. In products of this kind, the need is no less than in the air, and this is not an exaggeration.

So, the main ones in the human body:

• Active participation in the processes of regeneration. Protein provides the basis for normal cell division.
• Active participation in metabolism. As a result, there is a tremendous effect on the nervous system.

The consequences of a lack of protein

If in childhood and youth a person does not receive his required minimum of protein on an ongoing basis, then this leads to irreversible consequences, including:

• slow growth, in critical cases it is possible to completely stop it;
• hormonal imbalance;
• dystrophy;
• low level of immunity;
• problems with memory, the ability to perceive information;
• low level of performance.

According to this information, a person who ignores foods high in protein risks turning into a “vegetable” over time, depriving himself of the opportunity to lead a full life.

Protein composition

These substances of organic origin are composed of amino acids, which are divided into two categories:

• Interchangeable. There are significantly more of them - 80% of the total. This type of amino acid is produced by a healthy person's body on its own, without the involvement of "external" sources.
• Irreplaceable. More meager indicators - 20%. Here the body is powerless - it can get these amino acids only from food, where there is a lot of protein (table below).

Food

The most important in the formation of a complete human diet are proteins that are of animal origin. They contain a large number of amino acids that cannot be replaced. They are also most fully absorbed by the body.

In addition, you can find products of plant origin, where there are a lot of proteins.

More details in the tables below.

Foods rich in animal proteins:

Foods rich in plant proteins:

Thus, we have indicated the most popular foods with a lot of protein. The table, as you can see, even surpasses the "animal", but they are digested with less success.

Body needs

Each food product includes proteins, which differ in an individual set of amino acids. It is important to compose your menu so that everything you need comes in abundance. You also need to understand that the food on your table should include animal products, where there is more protein (beef, eggs, fish, and so on). "Meat" protein in the total ratio should be at least one third in relation to the "vegetable".

In this case, the needs of the body are calculated individually, based on such parameters as:

• growth;
• age;
• physical activity;
• mental activity.

There are many complex formulas on the network by which you can calculate the exact need for proteins. But if you take it in general, then the following dependence will do, on the basis of which you will already choose foods that contain more proteins, based on your needs:

• child under 1 year - 25 grams;
• from 1 year to 1.5 years - 47.8 grams;
• from 1.5 to 3 years - 53.1 grams;
• from 3 to 4 years - 62.9 grams;
• from 5 to 6 years - 72.1 grams;
• from 7 to 10 years - 79.8 grams;
• from 11 to 13 years old - 95.8 grams;
• teenager from 14 to 17 years old - 98 grams;
• women during the gestation period - 110 grams;
• women during lactation - 125 grams;
• sexually mature women - 97 grams;
• sexually mature men - 120 grams;
• sexually mature women engaged in heavy physical labor - 135 grams;
• sexually mature men engaged in heavy physical labor - 160 grams;
• men under 70 - 82 grams;
• women under 70 - 69 grams;
• men after 70 years - 76 grams;
• women after 70 years - 66 grams.

Protein for weight loss

Its role in dieting is difficult to overestimate, since:

At the same time, when compiling a daily menu, it is worth approaching wisely even those foods that are rich in protein. For example, the same egg. Where is the most protein in an egg? The answer is obvious. In this case, the yolk contains about 6 grams of fat. Therefore, even when preparing an omelet with vegetables for breakfast, "cut" it into 1 yolk and this will make the dish more dietary.

Light meals rich in protein

Of course, based on the tables above, it is easy to understand which foods are rich in protein. But how to combine them so that it is not only tasty, but also healthy? Let's give some recipes.

Spicy omelet in the oven with cottage cheese:

Beat spices, herbs and cottage cheese until smooth. At first, the cottage cheese will be cut off - keep stirring. Pour the mixture into a non-stick pan and bake for 20 minutes or until the center of the omelette stops shaking.

Thus, you got a dish where there are a lot of proteins - about 30 grams per serving, and at the same time a maximum of 170 calories.

Coconut cheesecakes:

• fat-free spreadable cottage cheese - 200 grams;
• chicken egg - 1 pc;
• rice flour - 30 grams;
• coconut flakes - 12 grams;
• sweetener to taste (you can stevia);
• baking powder - a pinch.

Preheat the oven to 180°C.

Mix until smooth half with the rest of the products (where there are a lot of proteins, as you can see). Put the mass in the form of flattened balls on a baking sheet covered with baking paper, sprinkle with the remaining chips and bake until tender (about a third of an hour). You can apply.

Too much is bad

Despite the fact that proteins are an indispensable element of human nutrition, their excess can significantly harm. This is manifested everywhere under the influence of those so popular today that cut down the amount of fats and carbohydrates in the food eaten. Of course, such nutrition systems have a lot of advantages in the eyes of followers - you can eat without counting calories, be always full and still lose weight. However, all this charm has a downside, whose name is ketosis. In other words, excessive zeal at the supermarket shelves in the process of choosing food, where there is a lot of protein, is destructive. In products of this kind there are enough preservatives and additives that provide the necessary taste, minimizing the intake of carbohydrates with fats. If this diet becomes a way of life, then the constant breakdown of fats will lead to the release of acetone, which will poison the entire body. In severe cases, even death is possible.

Protecting yourself from this is very simple - just stick to the basics of a healthy diet and balance.

You can often hear the phrase that protein is good for the body. But what are its useful features, few people say. In most cases, talk is about amino acids. At the same time, practically no one will say that in the process of assimilation of protein by the body, cells are saturated with amino acids. Thanks to this, cell regeneration is accelerated, and a healthy condition of hair, nails and skin is maintained.

The role of protein in body processes

The structure of a protein is made up of many compounds with other elements such as amino acids.

There are two types of amino acids in the human body. They are:

• Irreplaceable elements are formed in the process of vital activity of the body. It takes a lot of energy to create them. Their lack in the body can be expressed by a constant feeling of hunger. Therefore, intake through food is an important point in restoring the norm of amino acids.
• Replaceable items. They must be supplied in the right amount to maintain healthy processes. If you regularly eat food where there is little protein, but a lot of fats and carbohydrates, a metabolic disorder will occur. This will lead to serious health and weight problems.

Therefore, it is important to know which foods contain a considerable amount of protein and the rate of its use.

Main Functions

The number of protein functions in the human body is infinite. But the main ones are:

• construction role
• hormonal regulating
• saturates cells with other nutrients
• thickens blood at what performs a protective function
• stabilizes and maintains blood pressure at the proper level
• relaxes muscle tissue during prolonged tension
• contributes to the development of the fetus during pregnancy by saturating the elements necessary for growth

In nature, there are two ways of obtaining protein - through plant and meat foods. The protein element itself is not important for the body, but the product of the cleavage reaction itself in the form of twenty-two amino acids. It is believed that the saturation of the body with nine of them should occur in the process of eating food.

Regulation of the metabolic process with protein foods

Science has proven that high-calorie foods significantly speed up the metabolic process in the body. It affects the person. For example, during the period of weight loss, protein maintains vital organs in good shape, and also stimulates the immune system and the action of antioxidants. With the help of protein, the body receives all the elements necessary for vital functioning.

In addition to the above, food rich in protein of natural origin performs such an effect through the correct metabolism:

• reduces blood sugar, which significantly strengthens the cardiovascular system
• stimulates insulin to work properly to burn the accumulated glucose from the work of muscle tissues
• removes excess water from the cells of the tissues of the human body
• burns fat accumulation, which affects the normalization of human weight
• saturates cells with useful substances - this allows you to reduce appetite, since it is the brain that signals the degree of saturation of the body

All of these effects have long been confirmed by scientists. They found that in order to maintain health at the proper level, a person should consume 100 grams of protein per day, which is found in food of natural origin.

The history of the establishment of the daily allowance in the diet

When eating ingredients such as meat, cheese, milk or peas, the digestion process breaks down into food proteins and amino acids. Further, the resulting elements are in the blood and mixed with enzymes. This is how proteins are formed, which are necessary, for example, for the growth of muscle tissue.

Nutritionists believe that certain types of protein elements are not amenable to the cleavage process. This is due to the lack of the required enzymes. Therefore, different protein-rich ingredients have different degrees of absorption by the body. For example, eggs are digested by 95–100%, and pea porridge by 50–60%.

The paramount one who managed to make the calculation of the protein is Max Rubner. He substantiated two important processes - anabolism, when new elements are formed, and catabolism, when substances are broken down.

In the process of lengthy studies, this scientist found that the norm of protein per day is 0.3 g per 1 kg of adult body weight. In terms of diet, this equals 1 liter of milk.

Many modern scientists believe that this study was carried out a long time ago and has lost scientific justification.

New Standard Daily Protein Results

As already noted, today other approaches have been applied in calculating the protein ration for a person of different age categories. These rules look like this:

• for a middle-aged person, it is necessary to consume 1.5 grams of protein per day per 1 kg of body weight
• the infant period is required for enhanced development and growth of 2.2 grams of protein per day per 1 kg of body
• for children 7-10 years old, the daily intake of protein should not exceed 36 grams of the total amount per day
• expectant mothers during the period of bearing a child to the norm of an adult are supplemented with 30 grams of a solid number per day

All of these standards must be met under a number of circumstances. These include:

• parallel intake of other elements, such as carbohydrates and fats
• the degree of quality of the incoming protein should be significant with a complete amino acid set
• obligatory observance of the ratio between the amount of vegetable and animal protein - the first should be no more than 35%

From this it follows that under the conditions shown, the body of an adult weighing 65 kg is able to normally master 98 grams of protein. For people involved in sports, these standards are much higher and are calculated on an individual basis.

List of foods containing digestible protein

It has already been noted that not all proteins can be fully absorbed by the body. This is due to the presence in food products containing protein, other elements - fats and. Their large number inhibits the absorption of protein.

Studies show that foods containing only protein are food ingredients that are fully absorbed by the human body. This is due to the low dose of other elements in them. This is confirmed by the reason for the rapid assimilation. Only because of the high amount of cholesterol, nutritionists recommend eating no more than 1 - 2 eggs per day for an adult.

The second product in terms of protein absorption is steamed meat. The best here is lean beef and chicken. In 100 grams of the last product, 28 - 30 grams of protein.

Meat products containing the highest percentage of protein include:

• boiled veal meat - 100 grams of the product contains 30.7 grams of protein
• boiled chicken - 100 grams 25.2 grams of protein
• turkey meat boiled in water - 100 grams 25.3 grams of protein
• boiled rabbit meat - 100 grams contains 24.6 grams of protein

The fish products with the highest amount of protein include:

• boiled pink salmon meat - 100 grams contains 22.9 grams of protein
• flounder - 100 grams 18.3 grams of protein
• pollock in 100 grams contains 17.6 grams of protein
• pike perch in 100 grams has 21.3 grams of protein

The dairy products with the highest protein content are:

• milk - 100 grams contains 3 grams of protein
• kefir - 100 grams 4.3 grams of protein
• yogurt contains 5 grams of protein per 100 grams
• cottage cheese contains 18 grams of protein per 100 grams of product

Vegetable protein products are:

• boiled potatoes - per 100 grams 2.4 grams of protein
• rice boiled in water - 100 grams contains 2.4 grams of protein
• 100 grams of rye flour bread contains 6.5 grams of protein
• green peas have 5 grams of protein per 100 grams

Since childhood, every person has heard about the benefits of oatmeal porridge. It is believed that this product belongs to the category of "slow" proteins. It has little fat, but a lot of protein and carbohydrate elements.

Manifestations of insufficient amount of protein in the human body

To establish the fact of a lack of protein in the body, you do not need to have a conclusion from specialists. Just look at yourself in the mirror.

It can be confirmed by such factors:

• Flabby skin and sagging muscle tissue if a person is under thirty years old
• The skin of the face is covered with wrinkles and its irregular shape is observed
• Unhealthy and nails. Their structure consists entirely of protein and therefore the lack of this element immediately comes out.
• Weakening of muscle mass and formation of fatty deposits
• The presence of abnormalities in the digestive process in the form of constipation, flatulence and other symptoms
• Decreased resistance to stressful situations
• Rapid fatigue with light exertion

If more than half of these factors are present in the process of observing yourself, then you need to sound the alarm. First of all, you need to change your attitude to food.

It is important to remember that somatic diseases, such as the flu or a cold, can be the cause of protein deficiency. If present, the result of a blood test indicates a low level of hemoglobin and immunoglobulin.

The situation can be corrected, based on the use of foods containing a significant number of proteins. In addition, there should be food supplies with fat and carbohydrate elements.
