About action of a protein on a human body there is a set of the facts and myths.
We tried to understand them within this article.
What is a protein
The protein is a plain protein which consists of the amino-acid remains. It is to the main components of cages of animals, plants and microorganisms. Represents a component of muscle tissue and is a key dietary component.
Protein also call the type of sports food consisting of the concentrated protein.
Whether you know? For the first time protein was received from wheat flour by the scientist from Italy Iacopo Bartolomeo Beccari in 1728. And the composition of protein began to be studied with the beginning of the 19th century. It was so found out that it consists of synthesis of 22 amino acids.
Protein role in an organism
Protein in a human body performs several functions:
- structural — participates in creation of cages, fabrics, bodies;
- transport — is transported by oxygen from lungs to cages and also substances by birth;
- regulatory — carries out regulation of processes in cages and an organism;
- receptor — connects hormones and biologically active agents;
- protective — participates in process of blood clotting, regulation of acid-base balance, mechanical protection of mucous membranes, prevents infectious processes, neutralizes bacteria, viruses;
- catalytic — is carried out by a catalysis of various chemical reactions;
- alarm — transmits signals between cages, fabrics, bodies;
- motor — provides physical activity of an organism, including reduction of muscles.
What do a protein for sports food of
The ordinary person in the course of daily activity spends during a day of about 2 thousand kcal. In order that to fill them, 1.3-1.5 g of protein on 1 kg of body weight are necessary. While the athlete or the person who is actively engaged in physical activity can spend during a day from 8 to 9 thousand kcal that cannot be filled by means of only usual food. For this reason to such people recommend to resort to the use of the special sports food saturated with proteins — to a protein.
Proteins are the main construction material in an organism. Sources of protein can be animals (meat, fish, milk (cow, goat), eggs (chicken, quail) and vegetable (soy, lentil, oats, rice, peas, barley, nuts, sunflower seeds, cabbage, carrots, eggplants, greens, tofu).
To understand advantage and harm of a protein for an organism, it is necessary to know from what it is made. Surely regular customers of gyms ask this question, wishing to learn, protein sports food is a nutritional supplement or chemistry.
The protein can be a miscellaneous by origin, to structure, a receiving source. It includes several components, of which proteins of various origin are main. They are received by an extract from different products. So, the protein can include dairy, serumal, egg, soy, fish, meat, pea, vegetable proteins, casein.
Raw materials pass several extents of cleaning as a result of which powder which is presented in shops of sports food turns out. As additional ingredients add carbohydrates, fats, a vitamin and mineral complex, fat-burning components and other substances to protein cocktail.
Important! Buying protein cocktail, surely study its structure as it can include substances on which you have an allergy or individual intolerance. Consult with a protein occasion coach if you have difficulties with its choice.
Myths or reality
After we learned what represents a protein and what it is made of, we suggest to deal with the main myths which are handed down between visitors of gyms.
Proteins are chemistry (steroids)
That the protein is chemistry there is a resistant stereotype at people who did not understand heart of the matter. But, as we could see with you above, this sports food is made of natural products, mostly of milk (for 90%).
Protein bars are developed especially for weight loss or strict maintenance of muscle bulk.
For example, process of production of a serumal protein looks as follows: milk stvorazhivatsya, serum is filtered, from it fats and carbohydrates are removed. At the exit proteinaceous mix turns out. Then it is dried up to a condition of powder. Thus, at one fabrication stage of a serumal protein chemicals — only natural processes are not applied. To adduce even more telling argument on confirmation of a thesis that the protein is not chemistry, we want to note that artificial production of protein is quite expensive process. To extract protein from milk or other natural product costs much cheaper.
Chemistry can get to protein cocktail only in case it is made from the low-quality product containing chemicals. So, for example, if milk of a cow contains antibiotics, then, naturally, they will be also in serum from which the protein will be made.
Important! Upon purchase of sports food it is necessary to choose products only from the checked eminent producers to avoid the use of a low-quality product and lack of desirable result. It is possible to examine numerous laboratory testings of sports food and lists of the most quality and counterfeited products on the Internet.
Affects potency
Of course, each man is very much concerned by this question especially as answers to it are quite contradictory.
Let's begin with the fact that in this subject there is a substitution of concepts. Researches which were conducted concerning influence of a protein on potency showed that there is no communication between the use of proteins and male power. However as there is a widespread myth that the protein is steroids, and negative influence of steroids on a male reproductive system is proved, respectively, and protein food is considered harmful. Actually, it can bear harm to men if it is only made of low-quality raw materials. So, for example, the soy protein which costs little suspiciously contains women's hormones, and, of course, at its strengthened use the influence on potency will be noticeable.
If to speak about serious training by sport or body building, then male power can decrease because of excessive physical activities and insufficient completion of energy by means of food. To a tired and emaciated organism, naturally, will have no time for sexual inclination.
Causes failure in work of a GIT
Sometimes those who begin to accept a protein address with complaints to disorders of a digestive tract: locks, problems with appetite, meteorizm, diarrhea, belly-aches. The increased amount of protein causes increased load on a liver and development of putrefactive processes in intestines.
To eliminate or prevent failures in work of a GIT, it is necessary to take in addition the enzymatic drugs and to eat properly, depending on the arisen problem to adjust dietary food. Correction of a dosage of a protein helps to get rid of this problem also.
Councils for beginners: as it is correct to drink a protein; to begin to be engaged to the beginner in gym.
Causes allergic reaction
The protein in itself cannot cause allergic reaction. It is possible only in case at the person the intolerance of proteins or any components as a part of powder is observed.
Causes a renal failure
Influence of a protein on kidneys, including on development of an urolithic disease and renal failure, also became a subject of researches of scientists. However during them dependence it was revealed. Negative consequences arise only at people at whom the renal failure prior to reception of sports food was observed. Therefore the protein is contraindicated to such people.
Whether you know? For the first time dietary supplements began to release in 1934. Then Karl Reynborg after the conducted interrelation researches between quality of food and human health founded the first company on production of NUTRILITE vitamin supplements.
Injures a liver
There is an opinion that the use of sports food in the form of protein cocktails harmful influences work of a liver as loads it with an additional image, proteins exactly here are split. The strengthened food, really, renders big load of a liver, however, as doctors speak, it is absolutely incommensurable, for example, to the loading rendered by drugs, fast food or alcohol.
Nearly each person borrowing with sport available has today unique adaptation facilitating physical exercises and food — a sports shaker.
Promotes cardiovascular diseases
How the protein influences work of a cardiovascular system, several serious researches were conducted. Those from them in which it is told about influence of high-protein food on the frequency of mortality from cardiovascular diseases are considered as unconvincing. Though some of them found interrelation between such food and risk of development of coronary heart disease. Probably and its influence on appearance of hypertensia.
Influences development of osteoporosis
Information on influence of a protein on skeletal system is contradictory. It is proved that the use of this sports food promotes calcium removal. However it is possible only at its excessive reception. At the same time proteins promote production of calcium and its best assimilation.
All conducted researches in the field of influence of a high-protein diet on development of osteoporosis are considered as unconvincing for today. Most of them claim that there is no harm for health, and the advantage is proved insufficiently. The significant influence of a proteinaceous diet on calcium content in an organism is not revealed. Let's note also that the European agency on safety of food (EFSA) does not carry this product to harmful and such which have negative effect on skeletal system of the person.

Side effects of the excess use
So, for the ordinary person standard daily rate of consumption of proteins in day — 1.3-1.4 g on 1 kg of weight. For the person who is actively engaged in physical activities, limit standard daily rate — 2-2.2 g on 1 kg of weight. Usually advise to use 30-35 g of proteins at one time as additive to the main food. Everything that over this norm, it will be not good to go, and to the detriment. So, the excessive use of a protein can lead to deficiency of calcium, so, provoke problems with bones and frequent injuries.

The main danger of intake of the increased volume of proteins is that problems arise not at once, and after a while, in process of their accumulation in an organism. Therefore the person who is fond of protein cocktails without measure can learn only later a certain period about the arisen problems with health.
Unfortunately, often such consequences it is necessary to treat long and diligently. The special diet including more than sugar, food fibers, intake of the anti-inflammatory medicines and means improving a metabolism will be required. Treatment and restoration after uncontrolled reception of a protein will demand many forces, time and money.
Important! The expert has to paint a dosage of sports food and also time of its reception. In Network there is also a calculator of calculation of need for a protein for individual calculation depending on the sports purpose, a sex, age, weight and level of loading. It is uncontrolledly forbidden to use it as it leads to negative consequences for health, and sometimes — to irreversible changes in an organism or to it which will be very difficult to be restored.
It is also necessary to know that reception of a protein is limited for the people having obesity, violation of proteinaceous exchange, diseases of kidneys, heart and laktazny failure. The ban of the use of proteins extends to people at whom their intolerance is observed.
Video: advantage and harm of a protein
Use and advantage of a protein: responses
Generally, I drink a protein not so long, only several months, but I know a lot of the people which drink it many years and are alive-are healthy so far. To live in general it is harmful, companions athletes =) Occupations strength sports in the future too can be reflected - for example, in joints. Greasy food too harmful why you eat it? Also do not forget, a good training - a stress for an organism. And it means that it needs a lot of protein and energy. Helps an organism during a stress sports food. And like a kardiomegaliya the protein will cause nothing serious.

only thing: the perezhor of protein overloads a liver (the first sign - bitterness in a mouth). It is personally very difficult to me to eat on 2.5 g of protein on 1 kg of weight... But without protein additives that from usual food to receive 250 g of protein a day - it is necessary to have a paunch not small and plus should be considered that for successful digestion of this protein is recommended carbohydrates as much! And on some kachkovsky website read that garnish must be twice more than meat! Here are also forced to eat a protein. additives.

The protein is usual pure protein, without fat. And all. That falls from steroids, and not always. So you confuse warm with soft. Protein - the main construction material of muscles. After the training, within 30-40 minutes, the so-called protein window, i.e. the protein which came to this moment opens, it is acquired by an organism effektiny only. Thus having drunk cocktail from a protein you just will give more protein to muscles, and they will be able to construct them more. Analogy to bricks on building, 1000 people came for 30 minutes if did not manage to bring bricks, then 1000 people will leave and will construct nothing, and were in time - will build the floor.

Much on this subject I talked to the trainer. I do bodybuilding already over a year and frankly speaking never accepted a subject (proteins) in the form of any mixes. I consider that they can be replaced with the balanced so to speak special food or ingredients (Fish, meat, egg, kefir, buckwheat, etc.).

We hope that after reading of our article you will be able to make more conscious choice of a protein. It is especially necessary for you if you seek for accumulation of muscle bulk and decrease in volume of fat in an organism. And as for rumors about its harm for an organism, most of doctors at the use in a strict dosage harmful do not consider this product. Harm it is not confirmed also by numerous laboratory researches. Before the use it is necessary to check whether you enter the list of persons to whom this product is contraindicated.
