Vitamin B6 - instructions for use. Why does the body need vitamin B6 and what foods contain it. Why vitamin B6 (pyridoxine) is useful, as well as what sources are richest in it

Content:

Why do you need this vitamin what functions it performs. Where is it contained. Daily dosage. The danger of deficiency.

Vitamin B6 is pyridoxine hydrochloride, a key element of the diet and the basis healthy body. The substance was discovered by accident, at the beginning of the last century, but since that moment, scientists have not ceased to be surprised by its positive qualities.

Main characteristics:

easy solubility in water;
transparency;
inability to accumulate in the body;
participation in chemical processes;
complete withdrawal after 6-8 hours.

Scientists classify pyridoxine as a biologically active coenzyme. The substance is useful for the body and has a number of functions for its organs. It is present in nature in the form of colorless crystals that dissolve in water, and the resulting composition is not able to mix with essential oils and fats. Under the action of light, the element decomposes. It is able to withstand heat, but in the process of cooking (frying, boiling) it most of is still lost.

What is vitamin B6 for? What sources does it contain? What is its deficiency for a person?

Functions

Pyridoxine is a vitamin that is distinguished by chemical activity and is involved in many body processes. Its main activities include:

Stimulation and acceleration of metabolic processes. The "lion's" share of B6 is used to start and accelerate metabolism different type substances - antibodies, enzymes, protective cells and mechanical components involved in the construction of skin, muscles and bone tissues. Scientists have also proven that pyridoxine improves the process of assimilation of proteins from food, normalizes the processing of amino acids. For this reason, it is considered important vitamin for bodybuilders and children who have weight gain and height muscle mass is a common task.
Aid in the synthesis of neurotransmitters. Responsibility for the work of the central nervous system (transmission nerve impulses, organization of thought processes) are carried by neurotransmitters. In case of their deficiency, the risk of diseases and problems with the nervous system increases. Vitamin B6 normalizes the production of these vital elements. In addition, he is involved in a number of other processes that occur in the human central nervous system. It has been proven that regular intake of products with this vitamin guarantees improved memory, increased efficiency, improved coordination and concentration.
Providing cells with glucose. Pyridoxine activates the production of elements in the body that ensure the rapid transfer of glucose to cells. This means that the energy level depends on the sufficiency of B6 in the diet.
Acceleration of hemoglobin production. The vitamin is responsible for the production of red blood cells. But here his participation is indirect. It acts as a catalyst (accelerator) for ongoing reactions with proteins and is involved in the production of hemoglobin.
Normalization of amino acid metabolism. Considering why vitamin B6 is needed, it is worth noting its participation in the breakdown and production of a number of elements, including histamine, glutamine, prostaglandins and others. Each of them is important for the body.
Help with splitting fatty acids (unsaturated). The mentioned process is doubly useful - the body is provided with an additional supply of energy due to the breakdown of fats, and the risks of accumulating excess weight are reduced.
Maintaining muscle tone. It has been proven that pyridoxine optimizes the delivery of glucose to cells, which activates metabolic processes. In addition, a sufficient level of B6 is a guarantee of heart health and stable functioning of internal organs.
Normalization of lipid metabolism. It is known that pyridoxine is an element involved in optimizing cholesterol levels and supporting blood vessels in proper condition. Thanks to this action, it is possible to avoid problems with the heart and blood vessels.
Improving liver function. The action of the element has a positive effect on the functioning of the liver. A stable intake of the vitamin guarantees tissue regeneration and the utilization of harmful substances.

daily requirement

When planning your diet, keep in mind next norm pyridoxine:

An adult who has good health, needs at 2-2.5 mg B6 per day. On average, this is equivalent to eating 0.6 kg of bananas or 0.3 kg of fish.
Babies right after birth and up to six months of age need 0.2-0.3 mg.
With age, the need for the element increases. So, from the age of six months, the body needs 0.5 mg, and by the age of 8-10 already in 1.5 mg per day.
The body of women during lactation and pregnancy requires 2.5-3.0 mg vitamin per day.

The need for pyridoxine increases in the following cases:

During the reception birth control pills or medicines containing estrogen.
During pregnancy, when the body synthesizes increased amounts of estrogen.
During the diet. Often an inability to shed excess weight caused by the lack of useful element.
During the period of taking steroids (including cortisone).
14 days before the start of the menstrual cycle.
AT adolescence when the fat glands are in the active stage of work.
When playing sports or hard physical labor and so on.

Why is a deficit dangerous?

Vitamin B6 deficiency develops when there is a violation metabolic processes and wrong diet. The first manifestations of deficiency:

Deterioration appearance skin - cheilosis, seborrhea or dermatitis appears. Areas around the nose and eyes are considered the most susceptible.
Deficiency is manifested by itching of the head and increased dandruff.
Cracks in the corners of the mouth, seizures.
Stomatitis and more.

If you ignore the first problems, then the deficit leads to more serious consequences:

Conjunctivitis and vision problems. main reason- violation normal operation CNS.
Problems with the nervous system - the appearance of irritability, deterioration in performance, feeling constant anxiety and loss of sleep.
Malfunctions in the digestive tract. The main symptoms are vomiting, loss of appetite, nausea and others. Such symptoms in 90% of cases appear during pregnancy.
Deterioration of the brain. It has already been noticed that a lack of a vitamin leads to a decrease in mental endurance, a decrease in the flexibility of the mind.
malfunctions circulatory systems s, which is due low level production of plasma enzymes. The problem makes itself felt by pressure surges, the appearance of anemia, vascular disease, and so on.
Reduced immunity and excessive pain. The main reason is a decrease in the production of T-lymphocytes. The danger is that the symptom in question appears late, when the mild stages of deficiency are a thing of the past.
Joint damage, arthritis. In this case, arthritis develops with a regular shortage of the element (within 2-3 years).

Sources

To eliminate the problems discussed above, it is worth knowing the sources of pyridoxine and trying to saturate the diet with them. In nature, the vitamin is produced by almost all plants and even some microorganisms. Also, animals that take plant foods are able to accumulate it in the body. For this reason, meat products must be present in the human diet.

So, to the most useful products worth considering:

Legumes. The main sources of pyridoxine here are beans, peas and beans, which contain an average of 0.9-1.0 mg of vitamin per 100 g.
Sea fish(herring, mackerel). Here the content of B6 reaches the level of 0.8-0.9 mg.
Liver and kidneys- 0.6-0.7 mg.
tomato paste- 0.6-0.65 mg.
bell pepper(red) - 0.4-0.5 mg.

Also, in a small amount, pyridoxine is present in the following products:

chicken eggs - 0.35-0.4 mg;
potatoes, parsley and leek - 0.3 mg;
berries, vegetables and fruits - up to 0.3 mg.

When planning a diet, it is worth remembering the properties of the vitamin. As mentioned at the beginning of the article, the element disintegrates under the influence of elevated temperatures. It is also unstable in acidic and alkaline environments. For this reason, there is less pyridoxine in ready-made meat dishes than in the same bananas. To avoid deficiency, the diet should include greens, salads, fresh vegetables and fruits.

A small amount of the element is synthesized in the intestines, but this is not enough to meet the needs of the body.

Indications for use

Pyridoxine is prescribed for its deficiency (chronic or temporary). But there are other situations when an additional course is required. When should you take vitamin B6? What can it be useful for? The indications are as follows:

alcoholism;
CNS disorders, expressed by various neuritis, chorea minor, paranoia, depression;
toxicosis during pregnancy;
leukopenia;
hepatitis different stages and types;
atherosclerosis, pressure surges;
AIDS;
dermatitis;
seasickness;
shingles and others.

In all cases described, it is recommended to take pyridoxine in increased dosage(by doctor's prescription). Often B6 is included in the complex medicines in the treatment of enuresis, epilepsy and childhood autism. In addition, it is prescribed to smokers due to its ability to regulate lung function.

Interaction with other drugs

Pyridoxine actively interacts with B1 and B12. When mixing vitamins in one vessel (syringe), their neutralization is possible, that is, each of the elements is useless for the body. Also, the level of B6 is affected by the use of estrogens, which suppress its activity, which often leads to deficiency. In addition, alcohol abuse, irregular intake of corticosteroids, and penicillamine leads to a shortage.

Considering what vitamin B6 provides, and including it in the diet, it is worth considering Negative influence on the body in Parkinson's disease. Here the effect is twofold:

work is normalizing nervous system, which gives a positive effect;
suppressed action medicinal products which hinders recovery.

Drugs against seizures and tuberculosis are considered powerful antagonists. Their intake leads to a decrease in pyridoxine in the blood. Increasing the intake of B6 also acts suppressively on the mentioned funds.

Despite the availability of the vitamin in pharmacies, you should not self-medicate. Determine the need for pyridoxine and correct dosage only a doctor can. This is the only way to achieve positive results and avoid problems with overdose or deficiency.

Vitamin B6 or pyridoxine belongs to water-soluble vitamins, therefore it is unable to accumulate in the body (it is excreted within eight hours) and its supply must be constantly replenished. Its history began with its discovery as by-product in 1926.

By chemical composition is a group of derivatives - pyroxidine, pyroxidal and pyroxamine. Their effect on the body is equivalent.

The physical properties of pyroxidine are characteristic of all water-soluble vitamins. It is highly soluble in water and alcohols, but insoluble in ethers and fatty solvents. Decomposes under the influence of light, but is heat-resistant and does not undergo oxidation. When cooking, about 40% of the vitamin is lost.

The action of vitamin B6 (pyridoxine)

The action of the vitamin is seen in many chemical reactions of the body, it plays a key role in the metabolism of proteins and fats, without its assistance, oxalic acid forms compounds with calcium, which settle in the form of stones and sand in the kidneys. Acts as a natural diuretic.

Pyroxidine is called the most important female vitamin due to its influence on hormonal background women: it facilitates the course of PMS, it is essential during pregnancy, it alleviates the consequences of taking contraceptives. Taking vitamin B6 serves as a preventive measure against certain oncological diseases. hinders natural process aging and renders positive action on hair, skin and the entire external and healthy look generally. B6 has a positive effect both internally and externally, it is frequent and important component masks for hair and skin.

Another positive property pyroxidine is involved in the synthesis of serotonin, an antidepressant hormone.

In addition, he is an important player in the synthesis of hemoglobin and amino acids, which allow you to normalize the functioning of the nervous system, blood cells, muscle tissue development, control the level of potassium and sodium. Stabilizes the processing of cholesterol, preventing it from clogging inner walls artery, causing complex disease- atherosclerosis. In addition, vitamin B6 contributes normal functioning liver function and the uptake of glucose by nerve cells.

According to statistics, every sixth person in the world feels unwell precisely because of vitamin B6 deficiency.

Application for weight loss

About thirty years ago, a popular diet appeared in the United States based on the intake of foods that cause fat burning. Its main components are vitamin B6, apple cider vinegar, flax seeds, soybean oil. The main component of this diet is pyroxidine in amounts exceeding the daily dosage. The intake of these substances has an effect, subject to a change in nutrition to " the right products". The whole secret is that the effect of this diet is limited by the period of taking these products. BUT correct image life, nutrition and moderate loads, in principle, can give the same effect. However, pyroxidine has proven to be effective in the fight against obesity as an adjuvant.

Why do pregnant women need vitamin B6?

Pyroxidine is very important element in the formation of erythrocytes (blood cells), antibodies and components that transmit impulses of neurotransmitters, which is vital in the process of formation and development of the fetal brain and its nervous system.

In addition, for future mother there are a lot of benefits from it. Firstly, B6 facilitates the period of toxicosis, relieving the symptoms of nausea and vomiting. And secondly, it helps to relieve the tone of the uterus, especially the vitamin B6 complex with magnesium contributes to this.

Daily rate

The daily intake of vitamin B6 depends on age and gender, it is proportional to protein intake. So adults are recommended to take about 2.5 mg per day, children, depending on age - from 0.3 to 1.6 mg. For pregnant women, the need increases many times and is 4-6 mg.

Pyroxidine is able to be synthesized by the intestinal microflora, but there is little hope for this, because. few can boast healthy microflora in the conditions of a modern city and "artificial" nutrition.

Vitamin B6 has more effective action in the presence of vitamins B2 and B5, it is important to use it in combination with potassium and magnesium. They greatly contribute to the proper absorption of pyroxidine and the production of hydrochloric acid.

Interaction with other vitamins and drugs

Taking antidepressants and oral contraceptives, drinking alcohol and smoking reduce the absorption or neutralize the effect of the vitamin. Treatment with drugs such as penicillamine, cuprimin, as well as anti-tuberculosis therapy causes a lack of vitamin B6. When injecting B6, you should not combine it with vitamins B1 and B12, because. they cancel each other out.

Pyroxidine, in turn, has a depressing effect on drugs for Parkinson's disease.

Vitamin B6 (pyridoxine) deficiency

Vitamin B6 deficiency causes symptoms such as seizures and convulsions, insomnia, anxiety state, irritability and depression, loss of appetite, toxicosis in pregnant women, conjunctivitis and stomatitis, anemia.

Pyroxidine contributes to the treatment of diabetes in combination with magnesium, its lack can adversely affect the course of treatment. It is also noticed that problems with the pancreas are caused by vitamin deficiency.

Deficiency can lead to nervous breakdowns, irritability or apathy, it also manifests itself in hair loss and various skin diseases. Don't forget about additional reception while maintaining a protein diet, with hypertension and myocardial infarction.

An unpleasant consequence of the lack of this useful element can be a decrease in immunity and the body's instability to various infectious respiratory diseases.

Acute shortage - enough a rare event, there is usually a slight deficit.

Overdose of vitamin B6 (pyridoxine)

Hypovitaminosis is quite difficult to achieve, side effects are observed only with personal intolerance to the additive. And studies of taking vitamin B6 in 50-fold doses for several years did not cause complications.

According to experiments conducted by American researchers, it was possible to derive the maximum allowable daily allowance- 100 mg.

An interesting fact: an overdose of the vitamin can cause too vivid dream memories. This effect is observed when taking more than 500 mg per day.

Sources of pyridoxine

Sources of vitamin B6 are divided into products of plant and animal origin. Its largest amount is found in yeast and liver.

Vegetable sources - unrefined grains of all types of cereals and cereals, potatoes, legumes, bananas, nuts, cabbage of all kinds, soy.

Animal sources include liver, meat, dairy, kidney, eggs (especially in raw yolks), and fish.

It is very important not only to find a rich source beneficial substance but also to keep it as much as possible. Indeed, in the process of processing, enough is lost a large number of vitamin A. Here are some facts:

vegetables and fruits, when frozen, retain about 60% of pyroxidine, and bread baked from white flour contains only a fifth of the amount found in unpeeled grains;
when cooking rice or potatoes, 90% of the vitamin leaks out with drained water;
the conservation process retains about a third of B6.

Therefore, it is only necessary to slightly change the recipes in your kitchen and the reserves of pyroxidine in the body will quickly replenish. For example, it is enough to wrap potatoes in foil when baking, and when baking pies, add a little bran.

In addition, you can add to the diet the same walnut pies or hazelnuts, peanut.

Indications for appointment

Indications for the appointment of a vitamin are very extensive, which is due to its multifunctionality:

Taking pyroxidine has its own characteristics, and it should be prescribed with great care, especially for people suffering from stomach ulcers (may cause hyperacidity), and patients with ischemic disease.

Vitamin can be taken by oral route, injections ( subcutaneous injections, intravenously and intramuscularly). It is possible to administer it with droppers in case of problems with absorption in the intestines or with vomiting, when it is not possible to take it orally.

Vitamin B6 is a substance used to treat and prevent a wide range of diseases, including vitamin deficiencies in the body. In pharmacies, the drug can most often be found under the following names: Pyridoxine, Pyridoxin, Pyridoxine Hydrochloride, Vitamin B6, Pyridoxine Bufus.

The drug for injection is sold in the form of 1 ml ampoules containing a 1% or 5% solution. The ampoule is a glass flask packed in cardboard box. One box contains from 2 to 10 ampoules.

You can store the drug in its original packaging for up to 3 years in a place protected from light. The solution must not be frozen or heated.

The average price in Russian pharmacies is 50 rubles.

1 ml of the drug contains 50 mg of pyridoxine hydrochloride and 1 ml of water.

Pharmacology

Vitamin B6 is a cure a wide range actions that eliminate many disorders in the body. He participates in metabolic processes, in the regulation of metabolism of the nervous system. The drug is also used as a substance that promotes quick recovery patient after surgery.

Solution for injection contributes to:

Restoration of damaged tissues: bruises, hematomas, postoperative sutures.
Prevention of cardiovascular diseases.
CNS stabilization.
Bringing the metabolism back to normal.
Maintenance immune system and hematopoiesis.
Normalization of sugar content in diabetes.
Pyridoxine plays an important role in lipid metabolism, where it accelerates the absorption of saturated fatty acids and magnesium by the body.
positive effect on women's health hormonal disorders, is responsible for the production of the hormone serotonin, uplifting mood.

Indications

B6 is an important element necessary for the stable functioning of cells, metabolic processes, nervous and circulatory systems. The vitamin is delivered to human body with the food in which it is contained, and its deficiency can be observed when malnutrition, increased physical, mental load, during pregnancy or frequent stressful situations.

Injections with this drug are prescribed in the following cases:

Skin diseases: dermatitis, diathesis, cracked lips, psoriasis.
Disorder of the nervous system: neuritis, neuralgia, irritability, insomnia, depression, Little's disease, convulsions.

parkinsonism
Childhood autism
Diabetes
In some cases, pyridoxine can be used for alcoholism, as well as seasickness and even epilepsy.

Pharmakinetics

The drug is absorbed into small intestine, and then accumulates and is distributed in the liver, central nervous system and some muscles. The solution penetrates well into all tissues of the body. It is excreted mainly in the urine.

Contraindications

B6 is a gentle remedy for the body, but still has a number of contraindications. The drug is not used for acute liver damage, hypersensitivity to the components and coronary disease hearts.

With caution, injections are prescribed for peptic ulcers and problems since 12 duodenal ulcer. This is due possible increase acidity in the stomachs.

During pregnancy

With caution and only as directed by a doctor, the solution can be injected during pregnancy and lactation, but only in the most serious cases when the health benefits to the mother outweigh the risks to the fetus. Such cases include, for example, severe toxicosis.

Application

Pyridoxine is introduced into the body by several methods:

intramuscularly
intravenously
subcutaneously

Thus, the solution begins to act most rapidly when intravenous administration. This method is used for acute cases diseases. At chronic ailments and prevention, injections are given intramuscularly, and if the drug is used independently at home, injections are allowed subcutaneously.

Vitamin B6 is introduced into the human body through an injection, which can deliver both medical worker and non-professional. To do this, you must follow some rules:

Intramuscular injection should be given in side surface hips.
Pyridoxine is injected subcutaneously into the forearm.
Intravenous medicine can only be administered by a specialist.

Dosage

The daily dose of injection for administration differs depending on the disease of the patient. The most common pyridoxine liquid form are written thus:

From nervous disorders: 200 mg per day.
For parkinsonism: 100 mg per day.
Against convulsive syndrome - up to 600 mg per day.
From hypovitaminosis - 10-20 mg per day.

Therapeutic therapy traditionally lasts for a month for adults and 14 days for children.

In the case of other diseases, the amount of the drug required for use per day is prescribed individually by the attending physician, depending on the severity of the disease and other factors.

The drug has special indications in the treatment of anemia. Even with acute syndrome disease, it is worth injecting 100 mg of the solution no more than twice every 7 days.
For the prevention of hypovitaminosis in adults, the drug is prescribed at 4-5 mg per day, and for children, 2 mg per day is prescribed. Well preventive treatment usually does not exceed 2 months.

special instructions

Vitamin B6, like many other vitamins, is found in moderation in certain plants and animals. For example, in cereals, some vegetable crops, meat products, fish and its liver, cow's milk, chicken eggs. A person receives a substance from these foodstuffs and has no problems in deficiency, provided that daily dose vitamin A. It is:

For adults - more than 2 mg
For children under 1 year - 0.5 mg
For junior schoolchildren- 1.7 mg
For teenagers - 2 mg

Interaction

Vitamin B6 is incompatible with drugs such as thiamine and cyanocobalamin (vitamins B 1 and 12), ascorbic and nicotinic acid available in powder form.

Vitamin B6 (pyridoxine) is very important for the body, as it improves the absorption of unsaturated fatty acids. Together with calcium, it contributes to the normal functioning of muscles and the heart and their effective relaxation. It has been established that with a lack of vitamin B6, inflammation of the middle ear can occur.

Vitamins are usually assigned special medicinal properties. For example, vitamin A from " night blindness”, Vitamin C - “for colds”, B1 - “from nerves”, B2 - skin (“for beauty”), B3 - “for the brain”, B5 - “to continue life”, D - “replaces the sun”. But vitamin B6 has not yet been assigned an appropriate role.

Why does the body need vitamin B6?

What is vitamin B6 for? Pyridoxine is involved in many chemical reactions flowing in the body. Vitamin B6 can be considered a pantry of enzymes. In other words, without it, the origin and preservation of Life is impossible. He plays important role in the metabolism of fats and proteins. The more a person consumes them, the more vitamin B (as well as vitamin C) is required. Moreover, the end product of digestion is oxalic acid. But if there is not enough vitamin B6 in the body, one of the enzymes (transaminase) is blocked, and without it, oxalic acid cannot be converted into soluble compounds. And then oxalic acid combines with calcium and forms oxalates, which are deposited in the form of sand and kidney stones.

An interesting method of treating patients urolithiasis described doctors from Harvard ("Journal of Urology", 1974, October): within 5 years, 79% of patients were completely cured. They were prescribed 300 mg of magnesium and 10 mg of pyridoxine (that is, vitamin B6). Both of these drugs delayed the formation of oxalic acid, and already it was not in the urine. Such treatment, according to Harvard doctors, is “convenient, cheap and completely safe,” in addition, vitamin B6 can be considered an excellent natural diuretic.

Who needs

The American professor of Hungarian origin Albert Szent-Gyeri is credited with the discovery of several vitamins at once: ascorbic acid, thiamine, riboflavin, biotin and pyridoxine (in 1934). For more than 20 years he studied vitamin B6 and came to the conclusion that its intake should be increased from 2 mg for nursing mothers and 2.5 mg for pregnant women to 20-25 mg (almost 10 times).

An additional "powerful" portion of vitamin B6 is necessary for the following categories of people:

women who take contraceptives or pills and any medicines containing estrogen;
pregnant women in whose body is formed great amount estrogen, by the end of pregnancy, vitamin B6 is sometimes required a thousand times more than normal;
in the last two weeks of the premenstrual cycle, when the body produces largest number estrogen;
a large amount of vitamin B6 is needed by everyone who takes medications with steroids, such as cortisone;
those who, despite all efforts, cannot lose weight (the reason may be a lack of vitamin B6);
adolescents with acne increased activity fatty glands and difficult to treat. The rash can disappear within 5 to 21 days when using an ointment that contains 10 or even 50 mg of vitamin B6 per 1 g of cream (fat). First, itching stops, then peeling occurs, and finally, redness of the skin disappears.

How to determine the lack of pyridoxine

The lack of vitamin B6 in the body is difficult to determine. For example, if you suddenly experience “hellish pain” in the back of your ankle at night, so severe that you jump out of bed, you can assume that you are not getting enough vitamin B6 (but this can also be a sign of a lack of vitamin E or magnesium.

If there is a slight trembling in the hands, twitching of the eyelids, you are not sleeping well, you bad memory- these are not signs of old age at all, but only symptoms of a lack of vitamin B6 and magnesium!

The famous American nutritionist A. Davis writes in the book "Be Healthy" that vitamin B6 provides invaluable services in the treatment of diabetes. But the dose must be determined by the doctor. A. Davis believes that you can take vitamin B6 from 10 to 50 mg per day, adding 500 mg of magnesium to this.

Most diseases associated with the pancreas almost always require additional vitamin B6, and often vitamin E. According to A. Davis, symptoms such as nausea and vomiting in patients after surgery can be caused by a lack of vitamin B6 and quickly disappear with taking 10 mg or more of this vitamin.

Remember the words of Linus Pauling: “Physicians ignore the fact that molecular structure each of us is different, and apply general schemes in treatment that do not take into account this difference. But, despite the fact that the norm of vitamin B6 is usually 2 mg per day, many of us need 20 mg or even more.

Vitamin B6 to help lose weight

Obesity is a disease of civilization. People are susceptible to this disease because they move too little, do not work physically - machines do it for them; in addition, often the amount of food received exceeds the needs of the body, excess "fuel" is deposited in the form of excess fat. Get rid of excess fat possible in two ways. The first is to receive energy in the form of food in exactly the amount that the body needs, that is, not to eat more than the body can absorb. The second way is to increase physical activity. This path is for health special meaning: It prevents the conversion of excess nutrition into fat.

The heart that pumps blood to all organs, tissues and cells human body, vessels through which blood flows, capillaries - our small hearts, liver, lungs, kidneys, skin wear out prematurely and weaken if you have to serve the excess adipose tissue or non-working muscles and poorly functioning organs. Therefore reasonable physical work needed at any age. You have to force yourself to do physical work to save the body from obesity. A diet for weight loss can only help with this.

Diet for those who want to lose weight. In 1977, America was in vogue for the "wonderful, scientifically engineered" weight loss diet. Under normal rational nutrition, rich in fruits, fruits and vegetables, requires 50 mg of vitamin B6 daily, 1 teaspoon apple cider vinegar, 1/2 cup boiled flaxseed (it contains up to 90% lecithin), 1 - 2 tablets of multivitamins with macro- and microelements, 2 - 3 teaspoons of soybean oil on an empty stomach (or you can with salad vegetables).

It is better to add salt to dishes with crystalline salt rich in trace elements and only if there is no tendency to edema; in the presence of edema, it is better to use "Sanosol" instead of salt, which does not contain sodium.

All these products cause the burning of unnecessary fat in the body, as well as fats, often found in excess in food. Such a diet "guarantees" a slim figure.

What is the secret of such a diet? The main ingredient in this diet is a large amount of vitamin B6 (pyridoxine) - well above the recommended 2 mg. True, if we really ate rationally and moved a lot, exercised physical work, then we would, firstly, not gain weight, and secondly, we would have enough vitamin B6 in our diet.

What foods contain vitamin B6?

We talked about the importance of vitamin B6 for our health, now let's talk about where pyridoxine is found, what foods contain vitamin B6 in the most large quantities. So.

Most vitamin B6, as well as other B vitamins, is found in yeast, liver, sprouted wheat, bran and unrefined grains. There is a lot of vitamin B6 in foods such as potatoes (220 - 230 mcg / 100 g), molasses, bananas, pork. Vitamin B6 is also found in raw egg yolk, cabbage, carrots and dry beans (550mcg/100g).

But it is important not only to know and find a rich source of vitamin B6, but also to save it.

Frozen vegetables, as well as frozen or canned fruit juices and processed meats, lose a lot of pyridoxine. White flour and bread baked from it contain only 20% of the amount that is present in the unrefined grain of wheat. Together with the water in which the rice was cooked, we drain about 93% of the vitamin B6 contained in it; the same applies to the liquid obtained by boiling potatoes. During canning, 57 to 77% of this important vitamin is lost.

From vegetables and fruits the best source pyridoxine (vitamin B6) can be considered bananas, but this matters for the population of those regions where they grow all year round. In our country, potatoes rich in this vitamin could serve as such a source, if they were cooked skillfully, that is, they did not drain the water after cooking or baked in the oven, wrapped in foil. In addition, vitamin B6 is found in foods such as walnuts and hazelnuts, peanuts and sunflower seeds. Rich sources of vitamin B6 are: chicken meat, fish; from cereals - buckwheat grain, bran and flour from unrefined grains. When you bake pies, you should replace at least 10% of the flour with bran!

Vitamin B6 (pyridoxine) – water soluble vitamin group B, poorly soluble in fats. Relatively stable at high temperature, decomposes under the influence of light and oxygen. It is not synthesized in the body, sources of intake are food and pharmacological preparations.
