Interesting about proteins. Protein Facts: Interesting and Informative

Due to his appearance, habits and dizzying speed, squirrels have always been of interest to people. Among themselves, these rodents differ in coat color, some habits and what they eat. Their abilities are no secret to anyone, but scientists still continue to collect curious facts about proteins and share them with the rest. Below is a list of the most interesting of them.

In order for a squirrel to overwinter normally, it needs more than 3,000 nuts!


Under no circumstances should you feed peanuts to squirrels. These nuts are hard to digest.


Squirrels live alone, but in winter they gather in small groups of 3 to 6 individuals and hide in hollows.


It is strange that in the wild, squirrels only sometimes live up to 4 years, while in the house, on average, 10-12 live.


Squirrels can safely jump from a height of 30 meters. Helps them in this miracle tail. In squirrels, it serves as a parachute.


AT Ancient Greece people believed that squirrels needed a tail for a reason, but to hide in hot weather from the sun.


During mating, the male himself chooses his female. Most often, his choice depends on the splendor of the tail of the female.


Squirrels have a very short memory. While collecting nuts, they often forget in which hollow they hid their supplies.


In Croatia, for some time it was forbidden to eat squirrel meat during pregnancy, because it was believed that a child from this could be born with black skin.


Squirrels are born completely naked and blind, but already from birth they have long sharpened claws.

) told how an excess of protein in the diet affects the functioning of the kidneys, why dairy products affect sleep, and is it true that after a workout you definitely need protein.

Fact #1: The body needs both animal and plant protein.

Proteins are of animal and vegetable origin. Animals are considered more complete - they contain 8 essential amino acids that the body needs for normal functioning, B vitamins (their lack in the diet is the cause of stress, decreased physical activity, lethargy), iron necessary to maintain the immune system, thyroid gland, Omega -3 in the form of alpha-linoleic acid (required for the synthesis of other essential fatty acids).

Plant-based proteins should not be underestimated either - they are a good source of fiber that contributes to normal functioning. gastrointestinal tract. They are often called inferior - they do not contain all the essential amino acids (lysine, methionine, tryptophan, leucine, isoleucine, threonine, histidine). But they are also required in the diet. Approximate ratio of vegetable and animal protein: 45% to 55%.

Fact #2: Everyone's daily protein intake is different.

The amount of protein per day is individual for each person. Depends on physiological data and sports loads. On average, the norm for healthy person varies from 1-1.5 g per kg of weight, for pregnant and lactating women - up to 2 g per kg of weight.

Fact number 3: when losing weight, the protein rate is calculated individually

During the period of weight loss, it is important to correctly calculate the protein rate. During weight loss, you do not need to sharply increase its amount - it is not safe for health. If, for example, during the period of weight maintenance your norm is 115 g, when losing weight it increases to 140. The calorie deficit should not exceed 15%. BJU standard for weight loss: proteins - 15-35%, fats - 20-35%, carbohydrates - 40-65%.

Fact #4: Lack of protein in the diet has a negative impact on health

Proteins perform many different functions: protective (necessary for the normal functioning of the immune system), transport (carry oxygen and nutrients), regulatory, energy. They are also involved in the transfer of genetic information. But first of all, this is the main construction material"for the body (epithelium, for example, is updated every 3-4 days).

The lack of protein is detrimental - all metabolic processes worsen, the work of systems and organs is disrupted. First of all, the liver, muscles and hormonal levels suffer. Athletes lose muscle mass, there are problems with the respiratory and cardiovascular systems.

Fact #5: Weakness and headaches can indicate a lack of protein

General weakness is one of the signs of a lack of protein in the diet. It may be accompanied by muscle spasms, tremors in the limbs, and impaired coordination of movement. Due to protein deficiency, the synthesis of serotonin and other hormones is reduced - a person may experience sleep problems and headaches. Paleness, skin rashes, a tendency to puffiness, slow healing of wounds, hair loss, delamination of the nail plate - all this is a sign that you need to reconsider your diet and take tests.

Fact number 6: get better from protein


Get better not from proteins, fats or carbohydrates, but from a calorie surplus. And it doesn’t matter how you got them: a chocolate bar or two kilograms of fish. Another thing is that protein foods are less caloric. For example: the calorie content of pink salmon is 147 kcal per 100 g, Snickers is 488 kcal. Protein is an essential macronutrient in the diet. But any excess of calories is transformed into subcutaneous fatty tissue.

Fact number 7: 4 kcal is released when 1 g of protein is oxidized

Under the influence of pepsin, the protein breaks down into polypeptides and amino acids. From the latter, the body synthesizes new ones that it needs for normal operation, or converts them into energy. When 1 g of protein is oxidized, 4 kcal is released.

Fact #8: Excess protein in the diet puts more stress on the kidneys

From an excess of protein, in the first place, the kidneys suffer - the level of urea and uric acid in the blood increases. Failure to comply with KBZhU can also cause structural damage to the liver.

An excess of protein is one of the causes of osteoporosis. The body can only use a certain amount of protein. He recycles the rest. For this, the body needs additional calcium, which is taken from the bones. Keep a balance to keep healthy.

Fact #9: Protein can cause allergies

Protein intolerance - rare view food allergies. It most often occurs in the early childhood(fifty%). The reason is disturbances in the functioning of the immune system. The body mistakenly perceives a foreign protein as harmful chemical compound and starts attacking him. Histamine is released in the blood, causing an allergic reaction. Unfortunately, there is no medical treatment for this condition. You can get rid of allergies only by eliminating products containing the allergen.

Fact # 10: Protein diets give a temporary effect

Any diet gives a temporary effect. A lasting result can be achieved only by completely switching to proper nutrition. The most popular protein diet is Dukan (for which he was excluded from the medical register of France and International Association nutritionists). It implies a complete rejection of carbohydrates and unlimited consumption of animal protein.

Carbohydrates are the main source of energy. With a shortage, the body begins to destroy fat cells, and in parallel with them, muscles and glycogen stores.

As soon as you return carbohydrates to the diet, the body will begin to store them at a frantic speed - the kilograms will quickly return and they will bring “friends”.

Fact number 11: proteins, fats, carbohydrates are normally combined with each other

There are no products consisting of proteins alone - at least, carbohydrates are definitely present in them. And our body normally assimilates them together. The myth that proteins, fats and carbohydrates do not combine is fueled by supporters of separate nutrition, to which nutritionists also have many questions. The body needs all macronutrients - this is an indisputable fact.

Fact #12: Protein for sports nutrition comes from whey

Protein for athletes is obtained from whey (whey protein) or from cottage cheese (casein protein). For people who are not involved in sports, there is no point in additional protein intake - protein shakes are useless.

Fact #13: Protein powder is not "chemistry"

Protein powder is not chemistry if it is made from natural raw materials (milk). They are essential for quick muscle recovery after an intense workout.

Fact #14: A post-workout protein snack is just for building muscle mass.

Nutrition after a workout depends on what goals you are pursuing. If you are interested in extensions muscle mass, you need to use the "metabolic" window and eat something protein 20-30 minutes after physical activity (this is a source of amino acids necessary for recovery). Ideally, carbohydrates are also needed - they help replenish glycogen stores.

Fact #15: You need to get protein from different foods

To provide the body with all the necessary amino acids, you need to get them from different foods. Cottage cheese, for example, contains 14% protein with a complete amino acid composition. Vegetables and greens contain from one to two amino acids. And the more varied the table, the more likely it is that they will enter the body.

Fact #16: Protein intake should be even throughout the day

Protein in the diet should prevail in the evening - by the end of the day we do not need as much energy as at the beginning. Ideally, when the protein product is in every meal. Distribute your protein intake correctly. For breakfast, give preference to cheese, eggs, cottage cheese. For lunch - meat dishes, legumes, for dinner - fish and vegetables.

Fact #17: Lack of animal protein in the diet has an impact on the body

Whether positive or negative is the subject of fierce debate. Adepts of vegan diets say: without animal protein, it is quite possible to exist. I have a different opinion on this matter. The protein that enters the body with food is useless in itself. It requires only one thing - amino acids. From them, another protein is synthesized, "friendly" to our body. Non-essential amino acids can be synthesized. Indispensable - no. They only come with food. Methionine, for example, is an essential amino acid found in sufficient amounts in red meat. It is impossible to get it in the right amount from other sources.

Fact # 18: The main source of vegetable protein is legumes

Foods high in vegetable protein: beans, lentils, chickpeas, seeds, nuts, sesame. In sufficient quantities, it is found in buckwheat, wheat and cereals based on it: bulgur, spelled.

Fact #19: Protein is involved in brain stimulation

Protein is an important macronutrient for brain function. Amino acids secrete neurotransmitters - substances involved in the transmission of nerve impulses.

Protein deficiency leads to serious consequences. Fatigue and fatigue are just the tip of the iceberg.

The vegetable protein contained in nuts stimulates brain activity well - include them in your daily diet.

Fact #20: Proteins Differ in Digestibility

Proteins differ in the degree of digestibility. Slow ones are broken down by the body for a long time, dulling hunger. Fast foods are better absorbed and fill you with energy faster. The source of slow proteins is cottage cheese, cheese. Fast - meat, eggs, fish.

Fact #21: Milk protein is better digested after enzymatic fermentation

Milk is 90% water. The remaining 10% goes to casein and whey proteins - globulin and albumin. The first is characterized by difficult digestibility and poor digestibility (the main reason is insolubility in water). This is a minus in the nutrition of an adult and a plus in the nutrition of children. Low speed the breakdown of milk protein contributes to a dosed and uniform saturation of the baby's blood with amino acids - their level is stable for up to six hours.

The body of an adult better absorbs calcium caseinate - a protein obtained as a result of enzymatic fermentation of milk. Many nutritionists recommend giving up milk in pure form preferring lactic acid products.

Whey proteins have a balanced amino acid composition. By structure, they are as close as possible to the proteins of muscle tissue. They are often used to make protein powder.

Fact #22: Dairy products can cause heaviness

After dairy products, discomfort can occur if you have bowel problems. Almost a third of the population has lactose intolerance - " milk sugar". This condition is associated with a deficiency of the lactase enzyme, which is involved in its breakdown. If 30 minutes after a glass of milk you regularly experience bloating, this is a reason to think and see a doctor.

Fact number 23: a group of enzymes that break down protein - proteinases

These are enzymes of the hydrolase group that cleave peptide bonds. They are divided into six classes: serine, threonine, cysteine, aspartate, metalloproteinases, glutamine. The lack of enzymes is the cause of problems with the gastrointestinal tract, liver, gallbladder, pancreas.

Fact #24: The daily amount of protein in children's food is different from that of an adult

Daily protein intake baby food- from 2.2 to 3 g per 1 kg of weight (up to a year), from 36 to 87 g after a year. For the normal growth and development of the baby, it is important to follow these figures.

Fact #25: Chicken protein is a great source of protein

Chicken protein is a very good source of protein. It contains all the important amino acids and is low in calories. But be careful - chicken protein can cause allergies. This phenomenon occurs quite often. Chicken eggs rich in vitamins, iron, folic acid and other substances. The body can react to any of them! The most common cause is a reaction to albumin. Symptoms appear immediately: skin rash, itching, problems with the gastrointestinal tract and breathing. The norm of eggs per day is no more than three.

Fact #26: Protein foods affect mood and sleep

Proteins contain tryptophan, an amino acid responsible for good mood and normal sleep.

The lack of protein in the diet greatly affects the sleep-wake cycle in children. Due to the lack of protein, their synthesis of serotonin decreases - the baby does not fall asleep well.

You can solve the problem by increasing the intake of tryptophan: it is present in most plant proteins.

Fact #27: We have different protein digestion rates

We are all different, and the needs of the body too. Someone starts the day with a protein tomorrow and feels great, someone needs carbohydrates to start the body. Learn to listen to yourself. We have different speed digestion of proteins. One organism needs an hour for this, another three. This fact must be taken into account when preparing a diet.

Squirrels are small intelligent rodents. They are thrifty, agile and curious, known to both adults and children. Here are some Interesting Facts about them:

1. Squirrels are easily tamed and get used to humans. Despite this, they breed in captivity with difficulty. In the wild, the female brings 3-10 baby squirrels twice a year.

2. As you know, squirrels make reserves for the winter. But they don't eat everything. A good half of all these stocks remain untouched due to the "forgetfulness" of the squirrels, who cannot remember where they hid their stocks. In the end, these supplies become the prey of other birds and rodents, or simply disappear. Many of them sprout and turn into trees. It turns out that squirrels not only "feed" other animals, but also "plant" new trees.

3. Contrary to the popular belief that squirrels eat only nuts, these animals can also be predators. In fact, they are omnivores. Squirrels can attack small birds and rodents, as well as steal eggs from nests.

4. These animals owe their name to a peculiar monetary unit, which was squirrel skins. This monetary unit was called "bela".

5. Squirrels swim well. However, while swimming the main task squirrels - do not wet the tail. The fact is that if the tail gets wet, it will immediately pull the squirrel to the bottom. So, in swimming, the squirrel needs to be extremely careful and keep the tail high above the water.

6. In female squirrels, the tail is the main attribute of beauty. A beautiful fluffy tail is as valuable as long and Thick hair in a woman in the human world. Male squirrels pay more attention to females with bushy tails.

7. Even if the squirrel falls from the height of a multi-storey building, it will remain safe and sound, thanks to its tail. The tail serves as a parachute and rudder for the squirrel. With the help of its tail, the squirrel can make huge jumps from tree to tree without any danger.

8. A female squirrel can "adopt" a squirrel if he is left without parents. However, there are several subtleties here: almost always, a foster squirrel is, to one degree or another, a relative of a squirrel. In addition, the squirrel clearly calculates its capabilities so that the adopted baby is not at the expense of its own squirrels. Most often, she takes only one cub.

9. Shedding in an ordinary squirrel occurs twice a year, but the hair on the tail changes only once a year. In summer, the squirrel's fur is red, in winter it changes to gray, and tassels appear on the ears.

There are several types of animals that are well known to most citizens and residents. countryside. These include a cute long-tailed animal - a squirrel.

It can be found in addition to the forest and in the city park, and even in the yard of any private sector.

Squirrel: description, habits

A surprisingly cute animal, very curious in its habits, is a squirrel. Interesting facts characteristic of this animal are associated with various moments of its life.

They are smart, agile and fast. They communicate with each other, as studies have shown, with the help of a squeak and certain movements of the tail. The hair on the tail can reach a length of up to 3 cm, which makes it appear fluffy.

The head of the squirrel is rounded, with black round eyes. Long ears with tassels on top. The hind legs are slightly longer than the front. The fingers have sharp claws.

AT summer period time, brownish and reddish colors predominate in the color of the animal, in winter - gray and black, with slight brownish tints.

The body length of the squirrel is from 12.5 to 28 centimeters, the tail is from 19 to 30 centimeters. common squirrel weighs approximately 300 grams.

It is for its appearance and mischievous habits that the squirrel is one of the favorite animals of people.

Due to the fact that the front 4 teeth are constantly growing in squirrels, they must gnaw something all the time. In this way, they “grind down” overgrown teeth. If they grow too strong, the squirrels will not be able to eat properly, since the teeth will not be able to prick. The fate of such proteins ends with their death from starvation.

The most interesting facts about proteins are considered below.

types of squirrels

In total, about 200 live around the world. They live on all continents except Australia and Antarctica.

These species fall into three main groups:

  • tree squirrels building nests on trees;
  • earthen, nesting under stones in holes;
  • flying, one might say, living like birds high in the trees.

Birth of cubs, food

A female squirrel has from 2 to 8 cubs. Baby squirrels are born blind, naked and deaf. After two weeks, the coat grows, and after another one, the eyes open. The babies are under the care of the mother for about 10-12 weeks, during which the babies learn the rules of behavior.

Squirrels have a basic diet. These are nuts, seeds, berries, roots, bark, leaves, caterpillars, flowers, corn, and so on. Among all these types of food, the seeds of coniferous plants predominate: pine, fir, cedar and larch.

Interesting facts about squirrels can be seen by watching them in a city park or in a personal plot.

Squirrels can also eat "animal" food, such as bird eggs, small rodents and lizards.

On the winter period From time to time, squirrels arrange food supplies for themselves and their offspring, but it often happens that they forget the location of many "warehouses". But stocks feed many animals and birds.

Squirrel life environment, housing

The common squirrel is a forest dweller. Due to the fact that this animal usually feeds on tree seeds, it lives mainly in mixed coniferous and wide deciduous forests. They can also live in spruce forests, cedar forests, less often in deciduous forests and mixed pine forests.

Everywhere he finds a way out of the position of the protein. Interesting facts about these animals can be supplemented by the fact that in the regions of the Caucasus and Crimea they even mastered vineyards and orchards.

The animal is very lively and mobile, able to deftly jump from tree to tree with the help of a tail that serves as a rudder.

AT winter time an ordinary squirrel tries to move only along the tops of trees, where it hides in case of danger.

The territorial instinct in squirrels is rather weakly expressed, that is, there is no division of the territory into sections.

Shelters are built only on trees. In deciduous forests, the squirrel lives in a hollow, laying a soft bedding of leaves, grass and lichens. The nest is usually between five and thirty centimeters in diameter. common squirrel can take a standard birdhouse.

The most curious facts about proteins

Interesting facts about proteins have already been mentioned in the article, but the following information is more curious and fascinating.

  1. The name of the animal comes from the name of the coin "bela" in the form of animal skins. This one was introduced many centuries ago.
  2. An ordinary squirrel in one day can clean up to fifteen or more than a hundred pine trees. The weight of seeds extracted from one cone reaches only two tenths of a gram. In one day, a squirrel needs to eat more than a hundred cones.
  3. It is curious that, before hiding the mushrooms in the hollow, the animal first dries them on the branches.
  4. The squirrel sheds twice a year, except for the tail. On it, the coat is changed only once a year.

All the interesting facts about squirrels described above speak of the originality of this cute little animal. Consider another amazing view.

Flying squirrel: interesting facts

The flying squirrel differs from the well-known squirrel in the color of its coat. It has a beautiful silvery gray color. A long, very fluffy tail (about 14 cm) is the most important adaptation. She has no tufts in her ears. Huge eyes are black.

The body of the flying squirrel is flat, and there is a skin fold between the hind and front legs. It is a flying membrane that allows the flying squirrel to easily move between trees.

The squirrel's tail serves as a device that directs its movement. Accelerating well, she overcomes a distance of up to 100 meters in just one jump. That's where its name came from.

The flying squirrel is usually active at night and spends most of its life in trees. These unusual animals live in northern and middle lane Russia. Outside the country, they are found in Northern Scandinavia, Mongolia, Finland, China and Korea.

Endless interesting facts about proteins. It is curious that in Eastern Siberia campaigns of considerable groups of these animals were observed in search of food in the forests. Sometimes these masses of squirrels stretch for many kilometers. At the same time, even rivers do not stop them on the way, which they easily cross, funny with their lovely fluffy tails up.

The squirrel is a small and very intelligent animal that is known for its thriftiness, but here are some facts that we are sure you did not even suspect ...

Fact one: Croatian women are forbidden to eat squirrel meat during pregnancy, as local beliefs say that from this a child can be born black.

Fact two: Despite the fact that squirrels are easily tamed, they cannot breed in captivity. For this reason, there are still no reliable statistics on the number of annual mating periods, nor about the number of litters.

Fact three: Squirrels can be predatory. Despite the fact that in the minds of the inhabitants, the squirrel is just a textbook rodent that has a passion exclusively for nuts and seeds, in fact they are omnivores. They attack small rodents (including rabbits), birds and steal eggs from nests.

Fact four: As you know, squirrels make reserves for the winter. However, they eat, at most, a fourth of them. The reason for this is not that there are too many of them: it's just that the squirrel forgets where she hid them. Approximately two-thirds of the food forgotten by the squirrel eventually becomes the prey of birds and other rodents, and the last quarter simply sprouts.


Fifth fact: These animals owe their name to a peculiar monetary unit, which was squirrel skins and which (unit) was called "bela". And since squirrel fur has been valued since ancient times and has always been in demand, it can be argued that the money issue has been a “selfish matter” for more than a thousand years.

Fact Six: Squirrels are excellent swimmers. At the same time, their main task is to ensure that the tail does not get wet. This is explained by the fact that if the fluffy squirrel's tail gets wet, then it immediately begins to pull the squirrel to the bottom and it invariably drowns. Therefore, while swimming, squirrels hold their tail high above the water.

Fact Seven: For female squirrels, the tail is something like beautiful long hair in women. In any case, male squirrels show more interest in females with a magnificent tail than in owners of tails that are thinner.


Squirrels are very intelligent animals, in some countries they are considered pests.

Eighth fact: The name of the squirrels in ancient Greece was "skiurida". This name comes from the merger of two words: "skia" - a shadow and "aura", which means "tail".
