The chicken egg is one of the most affordable, tasty and nutritious food products known to man since time immemorial. Inside the dense shell there is a transparent, multi-layered protein mass, which has different densities to be held in the center of the core -. Protein is an almost colorless viscous liquid, odorless, has a gluing property, and forms a dense foam when whipped.

Egg white calories

The calorie content of egg white is 44 kcal per 100 grams of product.

90% of egg white is water, the rest is proteins of various types, such as ovoalbumin, ovomucin, lysozyme, etc. Egg white also contains: , vitamins, essential minerals: , (calorizator). Protein does not contain fat or cholesterol, so it is an ideal food for those recovering from viral, colds and other diseases. The protein of fresh chicken eggs has bactericidal properties, is necessary for hematopoietic processes, improves the functioning of brain cells, and is a preventative against the formation of cataracts. Egg white is a powerful immunostimulant and has the ability to neutralize the negative influence of the external environment.

In terms of nutritional value, an egg can replace 200 grams and 50 grams of meat. Chicken eggs have the highest digestibility among products of animal origin, which is 97-98%, that is, the egg is almost completely absorbed by the body

Egg white harm

Excessive consumption of eggs provokes an increase in the level of “bad” cholesterol, which is fraught with the risk of cardiovascular diseases. And protein can cause allergic reactions if you are individually intolerant to the product.

Egg whites for weight loss

To effectively “dry” the body (reduce body fat with minimal loss of muscle tissue), bodybuilders often use an omelet made from egg whites alone. Various diets include both whole eggs and separate whites. Examples include , .

Egg white in cooking

The most common dish made from egg whites is the airy meringue dessert (or meringue, it’s more common). Meringue is prepared as a separate delicacy, or coated with protein mixture on pies and cakes, then baked to a delicious crust. Protein cream - the name speaks for itself; it is used to fill tubes, eclairs and baskets, and is used as a layer for sponge cakes. Almost no dough can do without egg whites, be it bread, pastries, pancakes or dumplings with dumplings. Fresh egg whites are added to minced meat for cutlets or rolls to prevent the finished products from falling apart. Boiled egg whites (either as part of a whole egg or on their own) are ingredients in many appetizers, salads and soups.

Other uses of egg white

Chicken egg white is successfully used for medical purposes - with its help you can significantly relieve pain from burns and stop severe nosebleeds. Taking fresh egg whites internally will relieve pain and sore throat, restore a lost voice and is indicated for poisoning, especially with mercury vapor.

In cosmetology, egg white is used to prepare masks to improve the condition of hair; it is included in many products that smooth out wrinkles and maintain skin tone. An excellent mask for oily skin - and egg white, the mask removes oily shine and gives the skin a matte finish.

The egg is considered a unique and original food product. It is very valuable in its composition and effect on the human body. It is used not only as a food product, but also in medicine, cosmetology and other areas. If you look at the inside of the egg, it consists of two elements:

  • Protein;
  • Yolk.

How many calories are in the boiled egg white of one egg without yolk, how many calories are in the egg white

Most of the protein is ordinary water, and only the natural protein itself is allocated only 20% of its total mass. One cannot help but be interested in the question of how many calories are in egg whites, if they are so valuable and healthy. Protein itself is a low-calorie food product and is mainly albumin. Protein contains many useful ingredients and substances that have a positive effect on the human body. Consists of:

  • Vitamins K and group B;
  • Neocin;
  • Choline;
  • Protein;
  • Amino acids;
  • Minerals.

Each of these components has an auxiliary function for the body, because it helps various metabolic processes occur faster, promotes the appearance of cells and hormones, and also has tonic and antitoxic effects. So, how many calories are in an egg white without the yolk? The average caloric content of 100 grams of protein is 44.4 calories. This is very little, so even people on a diet can safely eat this product and not count calories.

Considering that the size of the eggs is ambiguous, and the weight as well, it is impossible to talk about the exact number of calories in the egg white of one egg. There are small, medium and large eggs. Their calorie content will vary from 70 to 80 or more calories. 1 white of one egg contains no more than 20 units. It is recommended to eat the egg boiled or fried, that is, after undergoing heat treatment. Such an egg is absorbed by the body much faster and more voluminously than the raw product.

Does the caloric content of cooked protein change?

Usually, when preparing a product, its calorie content changes significantly. When boiled, egg white retains its calorie content at its original level, so the question of how many calories are in boiled egg white disappears by itself. Both raw and cooked, the nutritional value per 100 grams of protein averages 44 kcal. When frying, the protein's calorie content will be higher due to the use of fat or vegetable oil. If you fry a whole egg, its calorie content will be on average about 360 units per 100 grams.

The yolk is another component of any egg. The composition of this component is also very rich in various beneficial substances and minerals. For example, the yolk contains huge portions:

  • Vitamins A, D, E;
  • Biotin;
  • folic acid;
  • microelements.

The calorie content of the yolk is about 60 calories per 100 grams of product. With this in mind, it is quite possible to even go on a diet that includes eating eggs. Their caloric content is minimal, but the benefits are simply colossal. Due to the valuable composition of this product, you can saturate your body with useful substances and minerals.

You don't have to eat just eggs. It is great for various dishes and used in cooking. In this case, they add taste and a touch of piquancy to the finished dish. With them, even a sandwich will be tastier and more satisfying, and, in fact, healthier. Moreover, they will not add significant calorie content to the sandwich. Absolutely anyone can profit from an egg. This is one of the quick options for a snack and food in general. In addition, it is very tasty and will allow you to immediately satisfy your hunger.

The human body needs a certain amount of nutrients necessary to convert matter into thermal energy. Therefore, a person’s daily diet should include proteins, carbohydrates, mineral salts, and vitamins.
Calorie content is the amount of heat energy released by a person as a result of the absorption of a particular product. A person should consume 2500-5000 kilocalories daily. But the less energy your body has to expend to digest food, the better. It will then spend its reserves on cell renewal, and therefore you will not age too quickly. Scientists say that 1500 calories per day with normal physical activity is optimal for a balanced diet.
Caloric content of food is the energy value of food products, expressed in calories (cal) or kilocalories (kcal). The calorie content of food is determined by the presence of unoxidized carbon and hydrogen atoms. A fat molecule contains more unoxidized carbon and hydrogen atoms than carbohydrates and proteins:
1 g of fat produces 9.3 kcal, 1 g of carbohydrates - 4.1 kcal, 1 g of protein - 4.1 kcal.
The number of calories depends on the work performed, physical activity, gender, age, cold or hot climate.
If you consume more calories than your body needs, the balance is disrupted. As a result, a fat layer is deposited. If you want to lose some weight, you can cut back on your calories. But you need to remember that the lower limit is 1200 kilocalories. A reduced diet can be used for no more than 2 weeks. Then try to maintain your weight at a normal level.
Each of us should receive as much energy as we expend during the day, i.e. Energy balance must be maintained in the body. If a person does not receive calories compared to energy expenditure, he loses weight. In cases where the energy influx from food exceeds the body's energy expenditure, fat deposition is inevitable. Excess weight is harmful, it sharply reduces mobility, reduces performance, worsens well-being, spoils the figure and, undoubtedly, reduces life expectancy. Excess weight leads to obesity, and then to obesity.

It seems there are only cerebral palsy in the comments...
Either it’s the fat that’s hitting the head, or, on the contrary, weakness of mental work, as a side factor of the chosen diets. But I started yelling from the comments.

Alexei

Or so 1g of carbohydrates is 4.1 kcal, that is, if you eat 100g of carbohydrates, you need to burn 410kcal. For example, a banana weighing 100 grams contains 23 grams of coal. Here is the formula 23 multiplied by 4.1 exactly 943 kcal you should burn by eating a 100 gram banana, this despite the fact that you are on a low-carb diet

Damn, how stupid you all are here..... I can’t imagine...... by the time I finished reading the great thoughts of great people, I almost lost weight from laughing. .. in short, short and clear!!! if you ate 1 bun weighing 100g, these 100g buns contain, for example, 52 carbohydrates, which means to burn this bun you need to burn 520 calories. Everything else is considered the same...

God you are stupid 9kcal-1 gram of fat

Dima

Have you all gone crazy here? to burn 100 grams of fat you need to burn 900 cells. I've been doing this for years

There is no fat in the white of a chicken egg, it consists of 90% water, and proteins make up only 10%. The special value is that there is no cholesterol at all.

One hundred grams of protein contains 44 kcal, and the white of one egg contains 18 kcal.

It also contains useful enzymes, glucose, vitamins, especially group B. Protein is source of niacin, which nourishes the brain. It also contains memory-improving choline. It also removes dangerous poisons from the liver.

One of the most common food allergies in young children is caused by eggs. Typically, this allergy "grows out" during childhood if excessive consumption of the allergen is avoided. Pediatricians recommend that children eat only egg yolk due to the development of an allergic reaction to the protein. In developed countries, products containing eggs, egg products, or which have come into contact with equipment processed with eggs are displayed in a separate section in supermarkets and are labeled accordingly.

For many years, in addition to increasing the popularity of eggs, bad qualities have been attributed to them. They are not classified as "functional" foods mainly because of their purported effects on cholesterol levels in the body. Research has shown that, despite decades of debate about the human body's protein needs, physically active people have increased their daily protein requirements. is that people with high physical activity sometimes achieve 100% increased protein requirements compared to people with a sedentary lifestyle.

Thanks to protein, the body receives amino acids that it does not synthesize, as well as carbohydrates, protein, etc. This product is the standard of nutritional value due to complete absorption.

Egg white used very widely:

  • as an ingredient in the recipe for some soups and many salads;
  • in cooking - for making creams and dough;
  • consumed raw or after various heat treatments;
  • used for the manufacture of cosmetics for hair and body care.

Is it healthy to eat eggs without yolk?

Nutritionists recommend eating only whites in eggs, and neglect yolks because the latter contains up to five grams of fat. Of course, if you eat an omelet made from two eggs in a day, then there is nothing wrong with that. It’s another matter if 10 pieces are “swept away” in the diet per day - in this case, the body receives as much as 100 grams of unwanted fat.

These daily needs are all around. The analysis shows that there is an increased need for proteins. Diets vegetarians with adult atrophic muscles. . It is a fact that they accumulate in the ocular lens and macular area of ​​the eye, where they have the highest concentrations. Some studies suggest that carotenoids may protect the eyes from damage from ultraviolet light by "detoxifying" oxygen-reactive bacteria, and increased intake of lutein and zeaxanthin has been shown to significantly reduce the risk of cataracts and age-related macular degeneration.

The yolk contains almost 0.2 grams of cholesterol.

This substance is necessary for the human body, but it synthesizes it itself and additional “help” from the outside is not required.

More recently, bodybuilders who consumed a lot of eggs to build muscle mass threw away the yolk, eating only whites.

But, as scientists have proven, they you need just enough cholesterol to repair muscle cells. They conducted experiments that showed that eggs should be eaten whole, since it is in this case that muscle growth is stimulated and strength increases.

Choline is an important component of the normal functioning of all cells. Here are the most important of its beneficial effects. Maintains the structural integrity and function of the signaling cell membrane, a major source of methyl groups directly influences nerve signaling, cell signaling and lipid metabolism. Additionally, choline deficiencies occur during pregnancy and breastfeeding and should be supplemented with additional intake. This is a critical point because the presence of choline is very important for normal brain function.

The harm of cholesterol, according to experts, is greatly exaggerated, since cholesterol plaques are deposited on the walls of blood vessels from the overproduction of this substance by the liver from the intake of large amounts of fat.

Eggs are a fairly common product in our refrigerator. It is easy to prepare and quite nutritious, and also easily accessible. We can call it an indispensable product in our diet, because almost no baked goods can do without it. We use them in different forms: raw, boiled, fried.

The Cholesterol and Egg Misconception

Does consuming eggs increase cholesterol levels in the human body? Most people will answer yes without even thinking about it, and this seems to be one of the biggest misconceptions in the world. Its consumption of cholesterol does not increase cholesterol levels in the body. The reason is that it produces more than 95% of the cholesterol in the blood. When we consume grains, sugar, soda or juices, they quickly turn into sugars. An increase in cholesterol is almost always associated with excessive consumption of grains and sugar and not so much the consumption of eggs or fats.

And you and I, girls, should know how much and what we use. Therefore, it is important to know the calorie content of even this product if we are watching our diet.

I read that eggs are an incompatible product with a diet, because they contain a sufficient amount of fat, but did you know that one egg contains only 50 kcal!

So, today we will talk about them in more detail, what benefits they bring and what harm they bring.

We hope that this article will help in identifying the valuable properties of eggs and revealing the myth of their demonic charisma. The article uses sources. 100% useful content and tips. 0% spam. Eggs are often blamed for causing high cholesterol. Find out here how many calories are in eggs, their nutritional value and eggs.

Eggs are mainly a source of complete proteins that are easily digested by the body. It is also low calorie. With more protein and a more easily digestible yolk. Nutritional value is found in eggs. They have a positive fat composition. In the 5 g of fat contained in one egg, only 0.1 g is "bad" saturated fatty acids, but many of these require unsaturated fatty acids for the body. Quail eggs are three times smaller than chicken eggs. They have a beige, dark-spotted shell.

How many calories?

First of all, the calorie content of this product depends on its size.

One hundred grams of chicken egg contains approximately 160 kcal. One piece usually weighs from forty to seventy grams. From here it is easy to calculate the calorie content of chicken eggs. However, the calorie content is also affected by the way it is prepared.

The Effect of Eating Eggs on a Healthy Diet

Cooked ones are used to prepare starters. They contain proportionally the same amount of calories, protein and cholesterol as a chicken egg and more fat. Eggs contain many unsaturated fatty acids, which improve memory and prevent diseases of the nervous system. Unfortunately, the yolk is a real cholesterol bomb. But on the other hand, it provides lecithin, which prevents its accumulation on the walls of blood vessels. You should not eat more than five eggs a week, including eggs.

Cooked calories

It is most beneficial to eat eggs raw, but there is no guarantee that they are free from salmonellosis. Therefore, it is better to cook this product.

Everyone knows that an egg consists of white and yolk. The caloric content of each part is different. The largest amount of calories is contained in the yolk, and the white contains three times less. Surprisingly, a boiled egg has the same amount of calories as a raw one.

Some nutritionists allow children, adolescents, pregnant women, nursing mothers and heavy physical workers up to seven. Egg consumption should definitely be limited to the elderly and liver patients. People with high blood cholesterol levels should not consume more than two units per week. Can be taken at a higher dose.

Eggs and Cholesterol When deciding whether to include eggs in your diet, you may want to consider the recommended daily dietary cholesterol limit. If you are healthy, you should limit your cholesterol levels to 300 milligrams per day. If you have heart disease, diabetes or bad blood cholesterol, you should limit your cholesterol levels to less than 200 mg per day. One large egg contains about 186 mg of cholesterol, all in the yolk. So if you eat an egg on a particular day, it's important to limit other sources of cholesterol for the rest of the day.

That is, it will contain 70 kcal.

This is an excellent option for breakfast, and besides, scientists have proven that the cholesterol they contain is harmless.

What is the calorie content of protein?

The white of a boiled chicken egg has little calorie content and is only 17 kcal, which is equal to about a quarter of the total calorie content.

Consider replacing meat with vegetables or avoiding high-fat dairy products on this day. Eggs can be safely stored in the refrigerator for about 1 month, preferably on a special shelf near the refrigerator door. Eggs are a very common product in home cooking. They are also very popular among athletes and people who have a healthy diet. The reason is that the small shell contains many beneficial nutrients.

Food composition from 100 g of raw chicken egg

To prepare a healthy, tasty and quick meal, there is no better product than eggs. They can be eaten even while dieting due to their high protein and low carbohydrate content. Many people on a diet prefer to use only the whites, because this is where the bulk of the protein is found, while the fat, as well as vitamins, are mainly found in the yolk. Once again, the yolk contains the very important substance choline - 1 g of egg. It is very important for proper brain development and is well tolerated by pregnant or breastfeeding women.

It is also important that the protein contains virtually no fat and contains all the amino acids necessary for the human body, as well as B vitamins.

What is the calorie content of the yolk?

The calorie content of the yolk is about 50 - 55 Kcal. It contains fats, proteins, carbohydrates, vitamins A, E, group B and microelements: manganese, iron, calcium, zinc and others.

Types of eggs and their characteristics

As we said above, different eggs and their types determine the nutritional content.

Calorie content after cooking

Fried - 196 calories, 14 g protein, 15 g fat and 0.80 g carbohydrates; Cooked - 155 calories, 13 g protein, 10.6 g fat and 1 g carbohydrates; Scrapper - 155 calories, 11 g protein, 12 g fat and 0.6 g carbohydrates; Eyes - 140 calories, 12.5 g protein, 9.50 g fat and 0.7 g carbohydrates; Dried - 600 calories, 50 g protein, 44 g fat and 1.5 g carbohydrates. Besides the undoubtedly remarkable nutritional composition, eggs are the subject of serious debate regarding their usefulness.

It also contains cholesterol, which is balanced by lecithin, making it safe. It is not recommended to consume the yolk simultaneously with other animal fats.

What are the calories in a hard-boiled egg?

Many are sure that the calorie content of 1 boiled egg, as well as a raw one, is 70 kcal, but this is not so. A hard-boiled egg has the least amount of calories, it contains only 50 kcal. This product can be stored for quite a long time, up to ten days.

Eggs are good for those who want to eat healthy

They are intended as a food that increases blood cholesterol levels, is a salmonella transporter and an allergen. They are easily absorbed by the body and are very necessary for the construction and repair of its cells. Protein contains essential amino acids that are in optimal balance. Due to its high biological value, egg white is recognized as a reference and compares proteins of other origins.

The fats contained in protein are mostly polyunsaturated and therefore harmless. This slows down the aging process, leading to changes in taste, liquefaction of protein, the appearance of indigestible sulfur and other compounds that irritate the stomach and liver. Before eating, eggs should be washed with warm water and boiled for at least 10 minutes. Cooking should not last long because the protein becomes difficult to digest. Fried eggs are difficult to digest due to the fat they fry, and they are not dietary. Eggs contain the most complete protein ingredients of any food.

  • It is advisable to consume eggs before the fifth day after laying.
  • Be sure to store in the refrigerator.
  • This also reduces the risk of possible microbial development in the egg.
What are proteins?

A boiled egg is an excellent option for those who are struggling with extra pounds.

Calorie content of soft-boiled eggs

Soft-boiled eggs do not lose their usefulness. They contain 70 kcal. This product is completely digested after a couple of hours.

The longer it cooks, the less digestible it will be. And in order to get soft-boiled eggs, they need to be boiled for only 3 to 5 minutes. A properly cooked product has a semi-liquid yolk and should only be served hot.

Proteins are the main component of all cells and tissues of the body. You know, tissues form organs, and they, in turn, form systems. Therefore, we can confidently conclude that proteins are the basic structural unit. Our muscle tissue and blood are structures that consist of more than 97% proteins. Proteins are made up of amino acids. Depending on how many amino acids are contained in one protein structure, proteins are simple or complex. From a dietary point of view, proteins are divided into fast and slow.

Unlike carbohydrates, proteins are digested in the stomach and intestines under the action of digestion. There they are broken down into amino acids. From the stomach and intestines, these amino acids reach the cells in which protein molecules are recreated, but this time to meet the body's needs. The better and balanced we eat, the frequency and choice of food, the better our protein intake.

What if you fry it?

For many people, their usual breakfast in the morning is scrambled eggs, so the issue of calorie content is very relevant. The calorie content of one fried egg, prepared chemically without oil, is approximately 110 calories. But many people fry them in oil, which contains fat, which increases their calorie content.

For example, chicken proteins are much more digestible than proteins from fatty, fatty red meats. What are the functions of proteins? The most important function we need to get enough protein every day is to increase its role in the body. They can also be used as a source of energy when there is a shortage of carbohydrates, but this is a compensatory mechanism to create balance, rather than imbalance, in the absence of one of the three.

Among all types of protein sources in nature, there are some differences in their biological value. This means that in order to be healthy and 100% unguarded in the right direction, we need to emphasize a specific set of protein sources among several main types.

Fry in oil

The number of calories in such a product can exceed 170 kcal, which is 2 to 3 times more calories than a boiled egg. Because of such a high calorie content, they are, as a rule, not included in therapeutic nutrition systems and diets for weight loss. If you do not want to give up the high-calorie scrambled eggs of 2 eggs, then you can try to reduce the nutritional value of this dish.

Biological value of proteins. As you can see, animal protein is more valuable. This is because they contain more essential amino acids. Plant foods contain more essential amino acids. Both types, however, are important for our nutrition. The ratio of essential to essential amino acids should be 1: To get this balance, it is best to consume 50% plant and 50% animal protein every day. For example, if you are eating on a health diet and need about 100 grams of protein, get 50 grams of animal protein and 50 grams of plant protein.

To do this, it is necessary to fry only the proteins, since the amount of carbohydrates in them is negligible and there is no fat at all.

What is the calorie content of an omelet made from 2 eggs?

One of the most common breakfast dishes is an omelet.

It is very easy to prepare.

You need to beat the eggs with milk, and pour the resulting mass into a frying pan, into which you first pour a little sunflower oil.

The calorie content of an omelet made from 2 eggs will be 118 Kcal, and if it is prepared from proteins alone, the calorie content will drop to 85 Kcal.

Tomatoes, cheese and other products are often added to an omelette, which increases its calorie content. For example, 100 g of an omelette with tomatoes and cheese can reach 342 Kcal. Breakfast in the form of an omelette is very healthy. It has optimal energy value, a boost of tone for the whole morning.

Beneficial features

  • The substances contained in the egg protect the optic nerve, preventing the formation of cataracts.
  • They also contain substances useful for hematopoiesis.
  • Lecithin contained in the yolk helps strengthen memory and improves mental performance.
  • Stimulate the immune system and promote weight loss.
  • Helps maintain healthy teeth and bones.
  • They contain the vitamin of beauty and youth – vitamin E.

Chicken eggs are very healthy, and it is better to eat them boiled, because with this processing they contain the least amount of calories and are better absorbed.

But, of course, there are quite a large number of products that have lower calorie content than a boiled egg.

However, before carefully counting calories, you need to remember its valuable and beneficial properties. Even more vitamins are contained in quail eggs, the calorie content of which, however, is significantly higher than that of chicken eggs (approximately 150 Kcal).

Egg categories are defined as follows

  • Highest category (B) - 75 g or more,
  • Selected egg (O) - from 65 to 74.9 g,
  • First category (1) - from 55 to 64.9 g,
  • Second category (2) - from 45 to 54.9 g,
  • Third category (3) - from 35 to 44.9 g.

The highest category is quite rare on sale, the third is even rarer. All other names of eggs: rejuvenating, rustic, this is nothing - a marketing ploy, supposedly they contain more selenium and other useful elements. But no one has yet conducted clinical trials on the effect of such eggs on human rejuvenation or health. And it is important for us to know only the composition of BZHU (proteins, fats and carbohydrates) and calorie content.


I buy a package, examine it, the composition of the product per 100 g of weight is written on the package. On the package of eggs the composition is written: protein 12.7 g, fat 11.5 g, carbohydrates 0.7 g, calorie content 157 kcal. Poultry factories analyze their products, and I hope that this data can be trusted.

All eggs appear to be the same size, but this is only at first glance.

I weigh it, the smallest egg weighs 66 g, the largest 72 g - and if you look closely, you can see that it is larger. I will select these two eggs from the entire package and will calculate the average values ​​from them.

Carefully break and separate the yolks from the whites. I weigh it on an electronic scale (error +- 1 g).

The shell weighs 8 g for an egg, which is 72 g; for the remaining eggs, which are 66-68 g, the shell weighs 7-8 g. The yolks weigh 18-20 g. The whites average 42-43 g.

Now let's turn to the nutritional value of chicken eggs. There is conflicting information on different websites and nutrition calculators. I’m trying to find something that sheds light on this confusion and compare it with institute textbooks, for example, on the merchandising of food products (Kazantseva N.S.). So, according to theory, the white of a chicken egg contains on average: water 80-85%, proteins 12-13%, carbohydrates about 0.7%, minerals 0.6%, fat 0.3%.

I remember what was written on the packaging of my eggs specifically.

100 g of the edible part of the egg contains 12.7 g of protein, then

64g eggs without shell (72g-8g) – 8.13g protein,

59g eggs without shell (66g-7g) – 7.5g protein. The average amount of protein is 7.8 g per egg.

Let's check the theory: Egg whites consist of approximately 13% protein, which means that 43 g of my egg white contains approximately 5.6 g of protein. In a smaller egg, 42g of protein contains approximately 5.4g of protein. The average is 5.5 g of protein. This is the number I will write down in my nutrition calculator. By the way, 0.7% of protein carbohydrates are 0.3 g, the amount of fat in protein is 0.13 g, and the calorie content is 25 kcal.

We can boil or fry this egg, and in any form it will contain the same 5.5 g of protein and 0.3 carbohydrates. But if we fry it in oil, the BJU changes.

Now the yolks. The chemical composition of the yolk is more vague: according to some data, the yolk contains about 31.8% fat, 16% protein, 0.2% carbohydrates, 1.1% minerals, and 50% water.

According to others - up to 33% fat, if you refer to Wikipedia, which refers to data from the USDA National Nutrient Database, chicken yolks weighing 17 g contain 4.51 g of fat - this is 26.5% - very little, some are wrong chickens in America, not like ours!

In general, I again go by the nutritional information on the packaging of the eggs I bought. It says 11.5 g per 100 g of egg weight. If you remember, fats are contained not only in the yolk, but in the yolk and the white; there is nothing in the shell except calcium salts.

  • There are 11.5 g of fat per 100 g of the edible part of the egg, then
  • 64 g of shelled eggs contain 7.36 g of fat.
  • For 59 g eggs without shell there are 6.7 g fat. The average is 7g fat per egg.

How to distribute all this between the white and yolk? It’s simple here: all data on the amount of fat in egg whites, according to different sources, are approximately the same - 0.3% fat. I have already calculated that this amounts to 0.13 g of fat. Then the yolk accounts for an average of 7-0.13 = 6.87 g of fat.

16% of the protein from the total mass of the yolk is on average 3g (I convert between eggs weighing 72 and 66g). And 0.2% carbohydrates 0.038 g. Average calorie content 74.3 kcal.

By the way, regarding the calorie content, they write everywhere that the yolk has three times higher than the white. Let's compare 25 kcal and 74.3 kcal - the difference is 2.9 times, so everything is correct!

To summarize, according to my calculations, the nutritional value of table eggs of the selected category.

Weight, g Proteins, g Fats, g Carbohydrates, g kcal
Nutritional value of the product 100 12,7 11,5 0,7 157
Whole egg C0 59-62 7,8 7 0,34 99
1 egg white C0 42-43 5,5 0,13 0,3 25
Yolk 1 egg C0 18-20 3 6,87 0,038 74,3

What would you like to say in the end? Of course, the difference in the chemical composition of chicken eggs is sometimes different. To calculate your diet, you can take any one - averaged from various nutrition calculator sites, or from a package of purchased eggs. In fact, you should rather believe the information that is written on the packaging of eggs. The fact is that the chemical composition of eggs depends on the breed of chickens, their age, and other factors that are individual at each poultry farm.
