Since how many years it is possible to drink a protein?"

The fashion for protein additives among athletes and the growing thin women concerned also the ordinary teenagers wishing to be distinguished from peers and to adjust actively formed body for a long time. However not all focus attention on what advantage or harm are born by the use of additional proteinaceous products to the growing organism and whether there are certain norms on which it is possible to calculate a necessary dosage of a protein on age. Let's understand the matter in more detail.

What is a protein

The protein is the popular nutritional supplement consisting of the useful amino acids connected in a chain by means of which it is possible to fill quickly in an organism proteinaceous balance and to grow up attractive muscle bulk.

The main functions of a protein in an organism:

• maintains hormonal balance. Is responsible for synthesis of insulin, hormone of growth and an insulinopodobny factor of growth. At men owing to frequent consumption of protein cocktails testosterone level increases;
• participates in transportation of vital nutrients: hormones, vitamins, lipids, carbohydrates, etc.;
• fills a power stock (provides normal physical activity);
• builds up cages, muscles and sheaves;
• accelerates course of different chemical reactions;
• prevents penetration into an organism of alien toxic substances.

Whether you know? Organic proteins in our body, as a part of two dozen amino acids, scientists counted about hundred thousand. It should not surprise if to remember that protein makes up to 1/5 all mass of the person.

Types of a protein:

1. Is the most popular among supporters of sport. For production quality whey from which fats and other nonprotein elements are filtered is selected. Consists of several proteinaceous fractions: large — beta lactoglobulin, VSAA amino acids, more small — immunoglobulins and peptides of albumine (glutathione). Positive sides: it is quickly acquired, has high biological value, "works" in muscle tissues within 2–3 hours, it is well dissolved and has pleasant taste.
2. Casein ("slow" protein). It is long acquired by an organism therefore it is not used to or after sports loadings. Casein pluses: provides continuous inflow of amino acids to muscle tissues, it is enriched with calcium, from 5 to 10 hours "work". Minuses: it is badly dissolved, disputable to taste.
3. Consists for 20% of serumal protein, for 80% of casein. Treats to the "slow" proteins suitable for the use for the night. Pluses: 3–4 hours, rather inexpensive "work". Minuses: contains lactose (does not suit people with intolerance), it is undesirable to accept to or after physical activities.
4. Soy (vegetable proteins). Contains defective amount of amino acids. Is not suitable for a set of muscle bulk at men, however the squirrel at people about lactoheat intolerance and vegetarians successfully compensates for the deficiency. Pluses: takes part in estrogenic development (women's hormones), lowers production of testosterone, reduces the level of harmful cholesterol, 3–5 hours "work" and are ideal for reception to or after the facilitated trainings. Minuses: it is badly dissolved, has unpleasant taste, differs from other types in the lowest biological value and amino-acid structure.
5. At the expense of the high biological value and degree of comprehensibility, is popular among all sports groups (the bodybuilders easy and weight-lifters, etc.). The main structure — quality egg whites. Positive sides: is ideal for reception of a sutr, to or after physical activities, contains a full-fledged set of amino acids, possesses the longest period of assimilation (till 7 o'clock). Minuses: high cost.
6. Multicomponent (complex). Is mix from other protein versions. As comprehensibility and to the content of amino acids it is considered universal. Pluses: contains additional amino-acid group (VSAA, a glutamine, creatine), it suits to the use to or after physical activities and also between meals, 3–6 hours, inexpensive and available "work". It is especially recommended to teenagers with "ectomorphic" type of a constitution for the use for the night.

Important! Protein powder is a "empty" product, vitamins and minerals are not its part. Besides, in pure form it has no pleasant tastes therefore the consumer should treat more attentively the structure specified on packing and to consider all artificial dyes and sweeteners added by the producer.

Use of a protein by children

Most of children receive a lot of protein with usual food if their diet is rather balanced. Therefore inclusion of protein additive or other additional sources in the kids menu always has to be followed by approval of the pediatrician considering physical, intellectual and emotional activity of the certain child. Independently to find out whether it is necessary to buy certain products from a protein and in what case children can include them in a diet, it is necessary to understand what their advantage and whether there are contraindications to the use.

It will be for certain interesting to you to learn, than protein cocktails are useful and dangerous.

Advantage

Salutary influence consists in the following:

• forms at the child of tissue of skin, healthy hair bulbs and nail plates;
• normalizes insulin level;
• adds endurance and energy;
• increases mental activity;
• normalizes hemoglobin level, positively affects composition of blood;
• participates in delivery of oxygen to bodies and fabrics;
• counteracts viruses and bacterial infections.

Important! The normal recurrence of the periods of a children's dream and wakefulness significantly depends on protein insufficiency in food. The sleep, in particular, is interrupted when the child lacks protein, decrease in serotoninovy synthesis is a consequence of what.

Harm and contraindications

At some pathologies the protein products can make serious negative impact on the young, actively growing organism. Additives are contraindicated at:

• individual intolerance;
• tendencies to frequent allergic manifestations of heavy degree (Quincke's edema, urticaria);
• any diseases of kidneys and liver;
• pathologies of a cardiovascular system;
• the lowered secretion of gastric juice.

Harm of a protein at uncontrollable application:

• failure in work of digestive system and intestines (nausea, swelling, diarrhea);
• renal failure;
• emergence of fat deposits;
• severe intoxication of an organism.

Since how many years it is possible to drink

There are no tight restrictions about from what age protein additives are necessary or necessary for children. The diet should be supplemented with proteinaceous and powder weight not only in 14–16 years as it is written in some trainer's recommendations. However anyway it is necessary:

• not to exceed the recommended dosage;
• not to begin the use without the permission of the pediatrician;
• not to mix proteins with other types of sports food.

Get acquainted in more detail with types of proteins in sports food.

The first and main that parents have to make, having consulted to the doctor — to define a lack of protein of the child's diet, and at his existence to calculate the correct dosage of additive.

Necessary amount of protein in day, proceeding from age and the child's weight:

As it is correct to use a protein

As a rule, the special measured glass, with a capacity of 30 g is applied to purchased packing of a protein. Such quantity should be parted in 200–250 ml of purified water or other drink to taste. For the best assimilation, it is desirable to divide the day dose established by the doctor into 2 receptions. For example, to use the first part of additive in a zavtrako-lunch interval, and the second — after the active games or special trainings. For additional vitamin and mineral feed, after protein additive the teenager can eat cutting from fruit or berries.

Whether you know? In the world there is a huge number of insects, using who, the person can enrich an organism with proteins, without needing additional sources. Such exotic food is sold mainly in Asia. Grasshoppers dishes, larvae of a silkworm and pavlinoglazok, a palm weevil, ants, flour hearts and even wood shchitnik (bugs skunks) are the most popular.

In general, to a healthy organism of the child on condition that it well eats, regularly breathes fresh air, drinks a lot of liquid and participates in active games, additional sources of protein are not necessary. However useful additives will be very opportunely to the beginning young athletes — the main thing that they were qualitative and were used strictly in a certain dose.
