Why does the body need chromium and what foods contain a useful mineral. What foods contain the most chromium and what is it for Where is the most chromium

More than 30 different trace elements are contained in the human body, while each of them performs its specific function, the violation of which can adversely affect human health and development.

Well, let's talk about the most important trace elements, without which the optimal functioning of our body is impossible.

In this article, we will consider not only the benefits of certain microelements, but also food sources for obtaining them.

trace elements

Trace elements are substances that are extremely in large numbers are present in the body. Despite this, their role in the full functioning of human systems and organs cannot be overestimated, because they take an active part in all biochemical processes.

Conventionally, microelements are divided into essential (or vital) and conditionally essential (that is, those whose biological function known, but the phenomenon of their deficiency is not observed or is extremely rare).

Essentials include:

iron (or Fe, according to the periodic table);
copper (or Cu);
iodine (or I);
zinc (or Zn);
cobalt (or Co);
chromium (or Cr);
molybdenum (or Mo);
selenium (or Se);
manganese (or Mn).

Conditionally essential are:

boron (or B);
bromine (or Br);
fluorine (or F);
lithium (or Li);
nickel (or Ni);
silicon (or Si);
vanadium (or V).

The benefits of trace elements

Ensuring metabolism.
Synthesis of enzymes, vitamins and hormones.
Stabilization of cell membranes.
Strengthening immunity.
Participation in the processes of hematopoiesis and growth.
Work regulation reproductive system.
Ensuring tissue respiration.
Ensuring the constancy of osmotic pressure.
Regulation and restoration of acid-base balance.
Promoting bone formation.

Important! Any imbalance (both deficiency and excess) of trace elements in the body leads to the development of a number of diseases, syndromes or pathological conditions, which are united under the term "microelementoses". According to studies, approximately 80 percent of the population has a more or less pronounced micronutrient imbalance.

Manifestations of micronutrient imbalance:

weakening of the immune system, which is fraught with frequent colds;
disturbances in the work of the endocrine, cardiac and nervous systems;
development of neuropsychiatric disorders;
the formation of tumors;
acne;
the development of inflammation;
deterioration in the condition of nails and hair;
development of skin allergies.

Causes of micronutrient imbalance:

stress;
radiation;
unbalanced or monotonous diet;
polluted atmosphere;
poor quality drinking water;
acceptance of certain medicines, which lead to the binding or loss of trace elements.

Conclusion! To live happily ever after, you must:

more to be on fresh air (keyword- "fresh");
less nervous;
drink purified water;
eat right, including in the diet foods enriched with trace elements.

What foods contain micronutrients?

Most trace elements enter the human body with food. plant origin, while in dairy products and meat their content is not very high.

Interesting fact! AT cow's milk there are 22 trace elements, but their concentration is extremely low, so this product cannot fully compensate for the deficiency of trace elements.

In general, each trace element has its own sources of "replenishment", which we will discuss in more detail later.

Iron

Iron is an element without which the process of hematopoiesis is impossible, as well as the creation of hemoglobin, which provides oxygen to brain tissues, endocrine glands and the whole body.

The benefits of iron

Stimulation of the process of hematopoiesis.
Strengthening immunity.
Promoting the synthesis of hormones thyroid gland.
Protection against harmful bacteria.
Removal of toxins and heavy metals.

cucumbers;
dried fruits.

Important! Iron is better absorbed from foods when combined with fructose, lemon and ascorbic acids, found in large quantities in fruits, berries and juices. Grains and legumes, strong tea, as well as oxalic acid make it difficult to absorb iron.

Copper

Copper, like iron, plays essential role in maintaining the optimal composition of the blood, namely in the formation of hemoglobin. Moreover, the iron that accumulates in the liver will not be able to take part in the formation of hemoglobin without copper.

The benefits of copper

Stimulation of connective tissue synthesis.
Promoting bone formation and full psychomotor development.
Promoting increased insulin activity.
Binding and excretion of toxins.
Strengthening the action of antibiotics.
Tissue regeneration.

In excess, copper has an effect on the body toxic effect which is manifested by the development of renal failure and gastroenteritis. In addition, excessive copper content in the body can be manifested by fever, convulsions, and the so-called "pouring" sweat.

Important! With proper and varied nutrition, a normal concentration of copper in the body is ensured (an excess of this substance is most often found in people who abuse synthetic dietary supplements).

What foods contain copper?

The daily norm of copper for an adult is about 3 mg per day, while pregnant and lactating women are advised to increase this norm up to 4 - 5 mg. Children up to a year need copper in the amount of 1 mg per day; from a year to three, the dose increases to 1.5 mg, while from 7 to 12 years it is recommended to consume at least 2 mg of this trace element per day.

Food sources of copper:

nuts;

In general, copper is found in almost all iron-containing products.

Iodine

The main function of iodine is to ensure the synthesis of a thyroid hormone called thyroxine. In addition, iodine is actively involved in the creation of phagocytes, which are a kind of "patrol" cells that destroy garbage and all kinds of foreign bodies directly in the cells.

The benefits of iodine

Normalization of work endocrine system by regulating the functions of the thyroid gland, as well as the pituitary gland.
Ensuring metabolic processes.
Contribute to normal physical and mental development (especially in children).
Accumulation warning radioactive iodine, which provides reliable protection against radiation exposure.
Strengthening immunity.
Regulation of the cardiovascular, sexual, and musculoskeletal systems.
Stabilization of the hormonal background.

Important! Iodine in pure form, which enters the body, is almost not absorbed, while its significant doses can provoke severe poisoning: for example, lethal dose pure iodine for a person is about 3 g (it is impossible to get such a dose with food enriched with iodine).

Excess iodine is fraught with the following consequences:

the development of hyperthyroidism, one of the manifestations of which is Basedow's disease with goiter;
increased irritability;
tachycardia;
muscle weakness;
sweating;
sudden weight loss;
tendency to diarrhea.

Iodine deficiency leads to such disorders:

diseases of the nervous system;
growth retardation and development of dementia in children;
thyroid diseases;
increased risk of developing cancer;
increased cholesterol;
congenital defects development;
miscarriage in women and sterility in men;
decrease in heart rate.

Iodine enters the human body with food, water and air, so people who permanently live by the sea rarely experience iodine deficiency, especially if they include iodine-containing foods in their diet.

What foods contain iodine?

The daily norm of iodine is 2-4 mcg per kilogram of body weight.

Golden Rule! The less iodine present in environment, the more it is necessary to introduce foods rich in this trace element into the diet.

rapid fatigue;
deterioration in skin quality;
hair loss;
infertility;
premature birth;
underdevelopment of the genital organs;
deterioration of vision.

Important! One cause of zinc deficiency is overconsumption of grains fortified with phytic acid, which interferes with the absorption of this element in the intestines.

However, not only a deficiency is terrible, but an excess of zinc, which provokes growth retardation and impaired bone mineralization. But an excess of this trace element is a rare phenomenon, since zinc toxicity is observed at dosages exceeding 150 mg per day, while the daily requirement for zinc is only 10-25 mg.

What foods contain zinc?

Products containing zinc:

Strengthening immunity.
Improving the absorption of iron in the intestine.
Promoting the regeneration of cells and tissues after various serious illnesses.
Strengthening the synthesis of proteins, without which the normal functioning of the body is impossible.
Facilitate the formation of insulin.

The lack of cobalt in the body negatively affects the work of the nervous and circulatory systems. I must say that the deficiency of this element practically does not occur (the exception is vegetarians, whose diet does not include animal products rich in cobalt).

But you should not forget about an overdose of this substance, although it is possible only if the medication is taken incorrectly and vitamin complexes containing cobalt. With an overdose of cobalt, symptoms of toxic poisoning develop.

Normalization of the permeability of cell membranes.
Strengthening of bone tissue.
Removal of toxins and other harmful substances.
Keeping on normal level blood pressure.
Decrease in cholesterol concentration, which is prevention cardiovascular disease.
Prevention of cataract development, but subject to the combination of this microelement with zinc.

Chromium deficiency contributes to an increase in blood glucose, as well as an increase in cholesterol levels, which can lead to the development of atherosclerosis.

The lack of chromium is typical for people suffering from diabetes, obesity, atherosclerosis. In addition, stress, heavy loads and protein deficiency lead to a deficiency of this element.

Manifestations of chromium deficiency:

severe baldness;
sleep disturbance;
frequent headaches;
impaired coordination of movements;
limb numbness.

If we talk about an excess of chromium, then it occurs when the concentration of this element in the air is excessive (we are talking about areas and cities with industrial hazardous industries). An excess of chromium can lead to the development of lung cancer, dermatitis, bronchial asthma and eczema.

What foods contain chromium?

The daily intake of chromium is 100 - 200 mcg per day (depending on age). These doses increase in acute infections, during pregnancy and lactation.

Food sources of chromium:

Prevention of caries: for example, molybdenum contributes to the retention of fluorine in the body, which does not allow teeth to collapse.
Improving the composition of the blood.
Promoting the production of hemoglobin.
Excretion from the body uric acid which prevents the development of gout.
Acceleration of decomposition and removal of alcoholic toxins.

Important! Regular and balanced nutrition fully provides the body with molybdenum.

An overabundance of this trace element can lead to serious disturbances in the functioning of the body. An overdose of molybdenum is manifested by a sharp loss of body weight, swelling of the limbs, irritability and mental instability. The main reason for an overdose is non-compliance with the doses of taking vitamin preparations with molybdenum.

Normalization of the work of the nervous and endocrine systems.
Improving the condition of the skin, nails, hair.
Elimination of inflammatory processes.

Interesting fact! Previously, selenium was classified as a class of toxic substances, which, of course, has a rational grain. The point is that in large doses(about 5 mg) selenium really has a toxic effect on the body, while a deficiency of this element (less than 5 micrograms) leads to the development serious illnesses and premature old age.

It should be noted that selenium deficiency is extremely rare, manifested mainly by general weakness and muscle pain.

An excess of selenium is provoked by the intake of inorganic forms of this element, which are part of the preparations. Signs of excess selenium are:

peeling of the skin;
hair loss;
delamination of nails;
tooth decay;
development of nervous disorders.

An excess of this element also leads to serious disturbances in the work of the body, in which the following are observed:

loss of appetite;
manganese rickets;
hallucinations;
weakening of memory and thinking;
drowsiness;
urination disorder;
sleep disturbance;
sexual weakness.

The main reason for excess manganese is polluted air, which is the fault of industrial enterprises.

According to the results of the studies, the risk of developing a boron deficiency is practically zero, since about 1-3 mg of this element enters the body daily with food, water and air, which corresponds to the norm.

Important! Boron is a potent toxic substance, therefore, with its excess in the body, irreversible changes leading to diseases of the liver, nervous system and gastrointestinal tract. Most often, an excess of this element in the body is provoked by the improper use of vitamin complexes, in which boron is present in a poorly digestible form. For this reason, both doctors and nutritionists recommend getting this trace element from food.

What foods contain boron?

As mentioned above, the daily need for boron is 1-3 mg, while it is enough to receive 0.2 mg of this trace element per day to eliminate its deficiency.

fish;
beer;
red wine.

Bromine

About 200 mg of bromine is present in the human body, which is evenly distributed throughout the body (its organs and systems).

The benefits of bromine

Providing an inhibitory effect on the central nervous system. In general, the so-called bromides are able to restore the balance between the processes of excitation and inhibition, which is especially important with increased excitability. For this reason, bromides are used in the treatment of neurasthenia and excessive irritability.
Activation of sexual function.
An increase in the volume of ejaculate and the content of spermatozoa in it.

An excess of bromine in the body leads to inhibition of thyroid function and prevents the entry of iodine into it. The main reason for the excess of bromine is the prolonged use of bromine preparations.

It is important not to confuse "pharmacy bromine", which looks like aqueous solution and used for disorders of the nervous system, with elemental bromine, which is a highly toxic substance that cannot be taken orally.

What foods contain bromine?

The daily norm of bromine is 0.5 - 2 mg.

Food sources of bromine:

bread and offal;
dairy;
peanut;
almond;
hazelnut;

The benefits of fluoride

Prevention of caries and tartar development.
Strengthening immunity.
Acceleration of bone healing.
Improved absorption of iron.
Removal of salts of heavy metals, as well as radionuclides.
Stimulation of hematopoiesis.
Prevention of the development of senile osteoporosis.

It is important to keep the balance of fluorine content in the body, since the difference between the useful and, accordingly, its harmful dosage is minimal. Thus, fluorine deficiency provokes weakening of the bones, the development of caries and hair loss. In turn, an excess of this microelement leads to inhibition of fat and carbohydrate metabolism, tooth enamel fluorosis, growth retardation, as well as skeletal deformities, general weakness and vomiting. In addition, with an excess of fluoride, increased breathing, lowering blood pressure, seizures, and sometimes even kidney damage are possible.

strawberry;
pumpkin.

Interesting fact! The stronger the tea and longer time his insistence, the more this drink contains fluoride.

Lithium

Interesting fact! During observations and studies, it was found that in regions where lithium is present in drinking water, mental disorders occur much less frequently, and the people themselves behave more calmly and balanced. Since 1971, this element has been used as an effective psychotropic drug in the treatment of depression, hypochondria, aggressiveness, and drug addiction.

The benefits of lithium

Decreased nervous excitability.
Regulation of fat and carbohydrate metabolism.
Allergy prevention.
Maintaining the functioning of the immune system.
Neutralization of the effects of alcohol, salts of heavy metals, as well as radiation.

thirst;
increased urine output;
hand tremor;
weakness;
violation;
coordination of movements;
vomit;
diarrhea.

Severe cases of poisoning may be accompanied by convulsions, loss of memory and orientation.

Lithium deficiency is replenished by the introduction of mineral water into the diet, as well as products containing lithium.

With an excess of this element, symptomatic treatment(In fairness, we note that severe cases of lithium poisoning are extremely rare).

What foods contain lithium?

Important! About 100 mcg of lithium enters the body of an adult per day, while scientists have not yet come to a consensus on the optimal daily dose of this element. At the same time, the toxic dose of lithium was determined, which is 90–200 mg, and it is simply impossible to obtain such an amount of lithium from food or water.

Dietary sources of lithium:

The trace element Chromium (Cr) is necessary for a person for the normal development of the body and the effective functioning of all organs, as it is an integral part of their tissues. The main amount of this substance contains bone tissue, pituitary gland, hair and nails.

Unfortunately, as the body ages, its content in organs and tissues decreases. Therefore, it is so important to get this trace element from the outside, for example, with food or taking special chromium-containing vitamin complexes.

About what products contain chromium Cr, we will tell on our website www.site.

What is the role of the element Chromium in the human body?

Its most important function is to enhance the effect of insulin in the metabolic processes it regulates. With its help, glucose is oxidized in fatty tissues, the rate of its penetration into cells and tissues increases.

It speeds up carbohydrate metabolism, regulates sugar levels. Therefore, it prevents the occurrence diabetes, hypertension, atherosclerosis, promotes lipolysis, increases muscle mass.

This trace element reduces the intensity of fat synthesis, reduces appetite. He naturally affects the appetite control center in the brain, which reduces the feeling of hunger and promotes natural decline weight.

With its deficiency, serious failures and disturbances can occur, as a lot of glucose accumulates in them, as a result of which they stop working correctly.

Chromium deficiency occurs when eating a large amount of carbohydrates that contain confectionery, flour products. Also, the lack of an element appears when frequent pregnancy, diabetes, age-related changes.

Due to its lack, heart disease can develop, blood sugar rises, kidney failure develops, and vision problems appear. Feeling worse, may appear inner restlessness. Also, an insufficient content of this element can provoke neuralgic pains, difficulties with thinking, decreased immunity, decreased muscle strength and muscle mass.

With a large deficiency, confusion may appear, intense thirst disruption of the central nervous system. A condition resembling diabetes, atherosclerosis, hypertension may develop, and cholesterol levels in the blood may increase.

What foods contain chromium?

Experts recommend daily dose chromium intake - from 50 to 200 micrograms. With a normal diet, a person receives about 30 to 40 micrograms. If the diet consists of canned foods or frozen convenience foods, then the body receives even less of this valuable substance.

Therefore, it is very useful to compensate for this deficiency by using products containing chromium in their composition. This is especially true for people with diabetes.

Chromium is found in following products supply:

Its highest content per 100 g of the product is in Brazil nuts. There is also a lot of it in the hazelnut.

Dates are the second in the content of this microelement. The main thing is that they can be eaten raw. After all, the more the product is subjected to heat treatment, the less chromium it contains.

The role of chromium in the body

The key function of chromium is the activation of insulin in those metabolic processes for which this element is responsible. So, with the participation of chromium, glucose is oxidized in fatty tissues and its penetration into tissues and cells is accelerated.
