Why is chromium needed in the human body? Symptoms of chromium deficiency in the body and the role of the element for human health

It is known that for the normal functioning of the body, among other things, trace elements and minerals are necessary. Today we will talk about why chromium is needed for the human body, what beneficial properties it has for health, and what a deficiency or excess leads to. Chromium is one of the biogenic elements that is constantly included in the tissues of plants and animals. This is a microelement that is vitally necessary for every cell of every organ and tissue of our body. Most of it in the human body is found in the muscles, adrenal glands and brain.

The optimal daily requirement for a microelement for a person is 50 - 200 mcg. It enters the body with food, water or air. Most of all, it is consumed during stress, heavy physical activity, infections and injuries. Deficiency can occur if there is insufficient intake from food (less than 20 mcg per day). Although for many people, consuming 25-35 mcg of chromium is considered sufficient.

And even with sufficient consumption of foods rich in chromium, it may not be absorbed if there is a deficiency of iron or. Its absorption is also influenced by such physiological factors like pregnancy and aging.

Yes and food modern man promotes increased excretion of chromium, as people eat purified and refined foods: wheat bread, sweets, etc.

Biological action

The importance of chromium for the human body is great. It has a huge role in the functioning of many body systems. Most importantly, chromium activates the work of enzymes that are involved in the metabolism of carbohydrates, the synthesis of fatty acids, proteins and cholesterol.

Scientists have long proven that beneficial properties capable of prolonging life. How?

• Glucose is needed to produce energy and ensure a full life. Chromium increases the effectiveness of insulin, which promotes the penetration of glucose into the cell and, together with insulin, helps the body absorb glucose, helping in carbohydrate metabolism. Therefore, this element is extremely necessary for patients with. If you eat enough foods high in chromium, it is quite possible that such a disease will not develop.

Glucose promotes the bonding of essential molecules in the body. After this, the molecules lose their ability to perform their functions. This process is called glycosylation. In terms of its ability to destroy the body, experts place it in second place after the damaging effects of free radicals.

• Regulates metabolism and helps maintain a healthy weight, helps convert fat into muscle mass, which is not stored later in excess on the body, which is very important for weight loss, reduces cravings for sweets.
• Increases muscle tone, performance and physical endurance.
• Promotes normal functioning of the thyroid gland, it is able to replace iodine if for some reason it is not enough in the body.
• By participating in the regulation of lipid metabolism, chromium promotes the breakdown of “bad” cholesterol and promotes its elimination, prevents the deposition of cholesterol plaques on the walls of blood vessels and the development of atherosclerosis, normalizes, and prevents the development of hypertension.
• Strengthens bone tissue and prevents the development of osteoporosis.
• Helps remove salts from the body heavy metals, toxins and radionuclides.
• Helps to survive stressful situations, improve reproductive functions in men.

Despite the enormous benefits, this microelement can have negative influence both with a deficit and with its excess.

How does the deficiency manifest itself?

Most often, a deficiency of this element can be observed in people who eat foods high in simple carbohydrates. The decrease is facilitated by frequent consumption of sweets and finely ground wheat flour products. A decrease in the amount is observed during pregnancy and while breastfeeding, with sclerosis of the coronary vessels.

One of the reasons for the risk of developing diabetes mellitus and atherosclerosis is precisely the lack of chromium in the body, which can manifest itself as an increase in the level of glucose and cholesterol in the blood.

If you experience a feeling of fatigue, rapid fatigue, causeless anxiety, headaches, numbness in the limbs, problems with sleep, an aversion to alcohol - all this indicates a lack of a microelement. With a critical deficiency, there may be incoordination, tremors and decreased sensitivity in the limbs and neuralgia. Lack of chromium affects the fertilizing ability of sperm, growth retardation and reduced life expectancy.

Externally, a deficiency of chromium can be recognized by the hair: it becomes dull and lifeless.

How does excess manifest itself?

But excess is also not the best in the best possible way affects well-being.

Often, excess in the body occurs when inhaling air with microparticles of chromium, as well as from uncontrolled intake of dietary supplements with this element. Excess can manifest itself in various inflammatory and allergic diseases, nervous disorders, liver and kidney dysfunction, and can cause stomach ulcers.

With an excess, it is possible to develop no less dangerous diseases that affect the mucous membranes of the upper respiratory tract and skin. The negative effects of chromium occur in workers in the chemical and metallurgical industries. If safety measures are not followed, lung cancer and asthmatic bronchitis may develop - the lungs are especially vulnerable due to the large number of small capillaries.

The need for chromium is best met with foods that contain this element in sufficient quantities. What contains the most useful microelement?

Most chromium is found in brewer's yeast and beef liver. Brewer's yeast must be poured with boiling water and left for 10-15 minutes, only after which it can be consumed.

Natural sources of chromium are:

• wholemeal bread, grains and legumes, cereals (especially pearl barley), wheat bran and sprouted wheat grains);
• meat, fish (mostly in bonito and tuna), seafood, lactic acid products;
• greens, vegetables (boiled potatoes with skins, green onions, carrots, beets, cabbage), fruits (apples, bananas, oranges) and dried fruits;
• berries (blueberries, blueberries, rowan, sea buckthorn, cranberries);
• nuts and spices;
• medicinal plants (melissa, cudweed, milk thistle, fireweed, etc.).

When preparing meals, please note that chrome will remain intact if you cook in stainless steel cookware. Know that chromium in dietary supplements is absorbed much worse than in food.

If flour and confectionery products form the basis of your diet, then do not go to a fortune teller, you are lacking chromium: with its deficiency, a strong craving for sweets develops. It is not difficult to detect a lack of microelement in the vast majority of overweight people, as well as in those who suffer from atherosclerosis of the coronary vessels and diabetes. It is a rare pregnant and lactating woman who does not experience a deficiency of chromium, because almost its entire supply goes to the fetus or baby - along with milk. Athletes and people engaged in heavy physical labor are also at risk.

Chromium is part of all cells of our body without exception. Normally, its total amount in the body is 6-12 mg. Research shows that women on average consume less than 40% of their daily chromium intake per day, while men consume less than 60%.

Who needs it?

Chromium is necessary for everyone who wants to lose weight, because it not only reduces cravings for sweets, but also prevents excess weight gain, since it regulates carbohydrate and fat metabolism. As soon as chromium levels decrease, unspent glucose turns into fat. And with sufficient intake of chromium into the body, on the contrary, it helps convert fat into muscle tissue. But, of course, if you do sports and not lie on the couch.

People with diabetes mellitus, especially type 2, as well as those who are predisposed to this disease, need this mineral no less. After all, a lack of chromium is one of the reasons for the deterioration of glucose tolerance in those over forty. And if there is enough chromium in the body, diabetes most likely will not develop at all. Chromium is also used in the complex treatment of diabetes, since in its presence a person needs less insulin.

Protects chromium from the development of atherosclerosis and diseases of the heart and blood vessels - it normalizes blood pressure, and also breaks down and removes “bad” cholesterol from the body and, conversely, helps “good” cholesterol accumulate. In men, a lack of chromium can impair reproductive function, so potential fathers need to make sure they have enough of this mineral. And for the thyroid gland, the role of chromium cannot be overestimated - after all, it can replace iodine if it is lacking in the body. Chromium is also indispensable for the prevention of glaucoma, the risk of developing which increases after forty years. Finally, chromium strengthens bone tissue, preventing the development of another age-related disease - osteoporosis, and also removes toxins, radionuclides and heavy metal salts.

From food - better

The rate of chromium intake into the body is from 50 to 300 mcg per day. It is better absorbed from organic compounds. Therefore, it is preferable to obtain the mineral from food. The most chromium is found in liver, meat, brewer's yeast, pearl barley, nuts, and dates. It is also found in milk, eggs, legumes, whole grain bread, seafood, broccoli, and apples. There is a lot of chromium in black tea and natural cocoa. But heat treatment reduces chromium content, so it is better to eat vegetables and fruits raw.

You can also take chromium as a dietary supplement. But first you need to consult a doctor. Uncontrolled use is dangerous, because an excess of chromium is no better than a deficiency: allergies, eczema, dermatitis may occur, and the functioning of the liver and kidneys may be impaired.

Chromium is a metal that is one of the key biogenic elements that perform important functions in the human body.

With a lack of chromium in the body, the functioning of many organs and systems is disrupted, and serious pathologies such as diabetes mellitus, atherosclerosis, and cardiac ischemia develop.

If there is a lack of chromium in the body, symptoms may appear with varying degrees of severity. If the deficiency manifests itself moderately, one of its clearest signs is the occurrence of increased cravings for sweets.

Chrome performs the following functions:

• Maintains the integrity of DNA and RNA structures, which under its influence function fully and correctly transmit information to cellular systems, which reduces the likelihood of a cellular mutation in which cells begin to divide uncontrollably, forming malignant neoplasms.
• Normalizes cholesterol concentration. With sufficient cholesterol content, cholesterol is eliminated faster and is not deposited on the vascular walls, which reduces the likelihood of atherosclerosis and related disorders: a detached fat clot can clog blood vessels various organs and lead to the development of acute ischemia. Therefore, a normal chromium concentration indirectly reduces the risk of developing pulmonary embolism, stroke, and gangrene of the lower extremities.
• Affects the mechanisms of fat breakdown. Chromium accelerates the process of losing weight, maintains weight at a normal level and increases the effectiveness of any workout.
• Regulates sugar content. This element, together with insulin, accelerates its absorption and reduces the risk of various pathologies associated with excess glucose and disorders of carbohydrate metabolism, including non-insulin-dependent diabetes, prediabetic conditions, atherosclerosis, endocrine pathologies, pancreatitis. Its sufficient concentration allows diabetics to improve their sugar levels.
• Positively affects the muscular system. Increases muscle strength and is actively used in bodybuilding to accelerate muscle gain and increase endurance. Active physical activity reduces chromium concentrations, so athletes take it in the form of supplements to prevent deficiency.
• Accelerates the elimination of toxic substances. If this metal is contained in sufficient quantities, the effect of toxic substances (including mercury, lead, zinc, cadmium, arsenic, radioactive isotopes, organic poisons) on the body's structures is reduced. Those who work with toxic substances should maintain chromium levels at sufficient levels.
• Affects tissue regeneration processes: increases the speed of healing of scratches and wounds. This is due to its effect on the concentration of glucose in the blood: with excess sugar, wound healing slows down, and chromium normalizes its content.
• Strengthens bone structures. Chromium enhances the production of dehydroepiandrosterone, one of the androgenic hormones. With a deficiency of this hormone, bones become thinner and the risk of osteoporosis increases. Therefore, to prevent this disease, it is useful to increase the consumption of products with chromium.
• Normalizes blood pressure levels. This metal affects the production of insulin. If the insulin level rises sharply, blood pressure also rises, and chromium prevents the occurrence of these surges and reduces the risk of developing arterial hypertension.
• Improves mental well-being. In people prone to depression, a pronounced deficiency of chromium is often detected, and with sufficient concentration, thinking, memory, mood improves, and concentration is restored. Its use is indicated for people with atypical depressive conditions: in 65% of cases, a diet with a high chromium content reduces the severity of this type of depression.
• Reduces the likelihood of developing eye pathologies. In combination with ascorbic acid, this substance maintains normal eye pressure, which prevents the occurrence of glaucoma.
• In case of iodine deficiency, temporarily takes over the functions of iodine and supports the normal functioning of the thyroid gland, preventing the development of endocrine pathologies.
• Positively affects the functioning of the heart. This element strengthens the heart muscle and supports it normal work. And the utilization of sugar and cholesterol reduces the load on the heart.
• Improves sexual attraction , especially in males, as it increases the production of testosterone and other androgenic hormones, which increase libido and potency.

This microelement is found in large quantities in foods such as:

• beef liver;
• fish (bonito, salmon, tuna, herring, capelin);
• seafood;
• yeast;
• dates;
• tomatoes;
• broccoli;
• potato.

Chromium also reduces cravings for carbohydrate and sweet foods, which makes it possible to maintain weight within normal limits. But this microelement will not contribute to weight loss without additional efforts in the form of nutritional correction and increased physical activity.

Symptoms of chromium deficiency

Early manifestations of chromium deficiency are moderate and cannot always be noticed on time. The following changes are observed:

• Thinning hair on the head. Hair looks faded, thin and dull, and active hair loss may begin.
• Dry skin. Problems with skin, nails, and hair are always accompanied by a deficiency of various microelements, including chromium.
• Sleep disorders, which can manifest as increased daytime sleepiness, difficulty falling asleep, shallow sleep with frequent awakenings, which entails additional deterioration in well-being.
• Fatigue. Performance is impaired, and it becomes difficult to withstand physical and mental stress.
• Headache, heaviness.
• Memory impairment. You may also have difficulty concentrating.
• Mental disorders: irritability, excessive level of anxiety that occurs without visible reasons, depressive states, emotional lability (frequent mood swings), apathy.

As the need for chromium increases, new symptoms are added:

• Deterioration in coordination of movements. Difficulties appear in maintaining balance, movements become imprecise, and gait changes.
• Numbness in arms and legs. Skin sensitivity may also be impaired.
• Tremor. Hands begin to tremble, and eyelids may tremble.
• Atherosclerotic changes. The concentration of low-density lipoproteins in the blood increases: they lead to the formation of cholesterol deposits in the blood vessels.
• Excess or lack of glucose. These disorders are associated with disruptions in the process of sugar absorption due to microelement deficiency.
• Pathological changes in body weight. The breakdown of adipose tissue is disrupted, the rate of calorie burning decreases, which leads to weight gain up to obesity. Also, in some cases, the opposite situation is observed: weight is greatly reduced, and dystrophy may occur.
• Fertility in men is impaired. Sperm become less active and lose the ability to fertilize an egg.
• Atypical depression. In addition to the classic depressive symptoms (apathy, depression, increased fatigue, self-hatred, decreased performance), there is an excessive craving for sweets. Appetite increases, weight increases, and permanent drowsiness is also present.
• Neuralgia. They are characterized by intense pain in the area of ​​the affected nerve and may be accompanied by numbness and changes in sensitivity.
• Development of prediabetes associated with impaired sugar tolerance. Later, non-insulin-dependent diabetes develops. People with diagnosed diabetes and chromium deficiency are more likely to develop complications associated with hyperglycemia.
• Deterioration of vision. Already existing vision problems progress, and the likelihood of glaucoma increases.

If an acute chromium deficiency occurs in a child, his physical development slows down.

Frequent stressful situations, excessive physical activity, poor nutrition with excess sugar, and lack of rest affect the development of chromium deficiency. Pregnant women are also at risk: the growing fetus actively consumes beneficial elements.

Acromegaly and gigantism are what increases the level of growth hormone. How to return hormone levels to normal if

The human body is a complex mechanism in which everything is interconnected, interdependent and requires clear dosages. If there is a deficiency or excess of any component, this negatively affects the functioning of organs and systems. The same applies to chromium, which is necessary to ensure the normal functioning of the human body.

Let's take a closer look at why the body needs chromium and what essential functions it performs.

1. The microelement is necessary for the synthesis of carbohydrates - substances that enter the body exclusively with food. They split, thereby releasing energy, without which a full human life is unthinkable. Chrome plays the role of an assistant in the normal course of these processes. Chromium is of particular importance for weight loss: if carbohydrates are absorbed actively and correctly, then the metabolic process proceeds at a normal speed. This means that excess fat deposits will not accumulate.
2. Chromium affects blood pressure levels, controls them and normalizes them, which is extremely important for people who have high or low blood pressure.
3. The trace element helps the body absorb sugar, thereby maintaining normal glucose levels. This is relevant for people suffering from diabetes, because if the body has the required amount of chromium, the need for insulin is reduced.
4. Chromium also fights harmful substances that accumulate in the body and poison it. The trace element helps eliminate toxins, as well as radionuclides that appear in the body of cancer patients who have undergone radiation or chemotherapy.
5. Experts call chromium a “builder” of bone tissue, which prevents the development of diseases such as osteoporosis. If the microelement enters the body in the required quantity, then the bones remain strong even in old age.
6. If there is an iodine deficiency, then chromium can partially replace this microelement.
7. Chromium is also necessary for men, since its lack is one of the causes of male infertility and decreased sperm motility.
8. Increases physical endurance, performance and muscle tone.

The body's daily requirement for chromium

How much of this microelement is needed per day for the normal functioning of organs and systems? It all depends on the age of the person. Let's take a closer look:

• infants - there is no need for daily intake of chromium into the body, since the microelement accumulated during intrauterine development and can be spent up to 12 months;
• children from 1 year to 2 years - 11 mcg per day is needed;
• children 3 - 11 years old - 15 mcg/day;
• adolescents from 11 to 14 years old - 25 mcg per day;
• from 14 to 18 years - 35 mcg per day;
• adults who lead a sedentary lifestyle - the daily requirement is up to 50 mcg for women and up to 70 mcg for men;
• adults who have heavy physical activity or are undergoing treatment need 150 - 250 mcg of chromium per day;
• expectant mothers and nursing mothers - from 100 to 150 mcg.

Products - sources of chromium

The table provides a list of food products that contain large amounts of chromium.

In addition to this list, a large amount of chromium is found in apples, cherries, plums, grapes, cranberries, sea buckthorn, rowan, as well as in radishes, beets and tomatoes.

Features of chromium absorption by the body

A number of factors influence how our body absorbs the microelement chromium. Let's take a closer look at them.

1. Insufficient amount of protein, iron in the body, as well as high level Sugars impair the process of microelement absorption.
2. Carbonated drinks and fast carbohydrates negatively affect the amount of chromium in the body; they “wash it out”.
3. Since calcium weakens the effect of chromium, these microelements cannot be taken together.
4. Iron also does not interact well with chromium due to the fact that iron prevents chromium from being absorbed and absorbed quickly.
5. Combining chromium intake with inhibitors, antacids, ascorbic acid, corticosteroids, beta blockers, and insulin is highly undesirable.
6. The trace element chromium is absorbed and broken down correctly only in the presence of amino acids that help this process. That is why a balanced diet is needed, in which natural products predominate, which will help the body receive a sufficient amount of chromium.

Why is chromium deficiency dangerous?

Chromium deficiency develops for various reasons. Many experts claim that the amount of this microelement in food is very low. This is due to the fact that due to the use of certain types of fertilizers, the soils have become excessively alkaline. However, even if the required amount of chromium enters the body with food, the microelement may not be absorbed and quickly eliminated. One of the reasons for this failure is metabolic disorders.

Let's figure out why chromium deficiency is dangerous for humans and what are the consequences of a lack of this microelement in the body.

1. If the patient is diagnosed infectious diseases, atherosclerosis, obesity, lack of protein; if the patient is exposed to frequent stressful situations or heavy physical activity, then the amount of chromium decreases. This is reflected in the condition of the hair, which becomes brittle, dull and begins to fall out.
2. With a lack of chromium, rapid fatigue occurs, sleep is disturbed, causeless anxiety and headaches of varying intensity occur.
3. If chromium deficiency persists for a long time, the sensitivity of the limbs noticeably decreases, trembling appears, coordination is impaired, and diseases of the cardiovascular system develop.
4. Gradually, harmful cholesterol accumulates, begins to destroy and clog blood vessels, and there is a risk of atherosclerosis.
5. The body can no longer absorb glucose normally, so its amount in the blood is either less than normal or more. Hypoglycemia or hyperglycemia develops, which can provoke coronary disease, diabetes mellitus, and sharp fluctuations in weight (some patients lose excessive weight, while others develop varying degrees of obesity). Men experience various reproductive dysfunctions.

In such situations, treatment is required, which is prescribed exclusively by a specialist after an examination. First, you should review your diet, introduce seafood, fresh fruits and vegetables into it. Upon appointment medicines It is necessary to strictly adhere to the dosage, since an excess of chromium is dangerous to health.

Excess chromium

Everything, as we know, is good in moderation. An increased content of chromium in the body, significantly exceeding standard values, is no less dangerous for the body than a deficiency.

• the body's defenses decrease;
• there is a risk of poisoning;
• inflammatory processes of various localizations develop;
• the liver and lungs are affected;
• nervous disorders appear;
• the skin reacts with dermatitis, eczema, allergies;
• mucous membranes become ulcerated;
• bronchial asthma and bronchitis of an asthmatic nature occur;
• the development of malignant neoplasms (primarily lung cancer) is possible.

Let's consider when situations may arise that result in an excess of chromium in the body.

1. Uncontrolled use of dietary supplements or medications containing chromium.
2. The human body does not have enough iron and zinc, which provokes active absorption of chromium.
3. Work at enterprises containing chrome dust in the air. As well as living in industrial areas where there is air pollution with this microelement.

If symptoms of a deficiency or excess of chromium in the human body develop, it is necessary to seek medical help. Only a specialist can realistically assess the patient’s condition and prescribe appropriate treatment after conducting a preliminary examination. Self-medication is strictly not recommended.

Many elements involved in various processes in our body are practically irreplaceable. And their deficiency can affect not only health, but also lead to more serious and irreversible consequences. The chromium element is deservedly considered a fat-burning substance. However, there is an even more important property of this element. It is essential in the production of a substance that controls blood sugar levels, namely insulin. While insulin is produced by the action of the pancreas, Cr comes to the aid of the latter. Insulin protects human health from excess sugar in the blood and from glypoglycemia - insufficient amount of sugar in the blood.

Chromium tablets

The lack of a completely microscopic particle of this element can lead to the development of serious pathologies. And exactly, as mass preventive examinations show, the majority of those suffering in different forms diabetes mellitus and obesity are found to be deficient in Cr. And the reason for this is unhealthy food such as fast food, which in its composition is almost completely devoid of Cr. For people who want to send overweight, you can purchase special vitamins with chromium for weight loss. However, when using any preventive medications containing a beneficial element, we must not forget about the necessary daily norm, amounting to 150-200 mcg. Dosages with a smaller amount of the substance will not help compensate for the lack of the element.

Also, when choosing preparations with Cr, one cannot ignore the nuance that it works extremely effectively with certain substances of plant origin. They affect carbohydrate and fat metabolic processes in the body. In pharmacies you can find vitamins with chromium, for example. You should read the annotation carefully. It also makes sense to think about purchasing Cr in pills. In this case, it will be very easy to calculate the daily dose.

What foods contain chromium?

Most chromium is found in foods such as fish, meat and poultry.
For optimal Cr production, amino acids are needed, which are found in many vegetables. Therefore, it is recommended to definitely add vegetable salads and fresh vegetables to your diet, combining them with meat and fish dishes.

However, the element cannot retain its beneficial properties after food processing. After cooking many ingredients, no more than 10 percent Cr is retained.
The content of Cr in the human body is from 6 to 12 μg.
The daily requirement of Cr for an adult is from 50 to 200 mcg. For people involved in sports and heavy physical labor - 150 - 200 mcg. For representatives of the fair sex expecting a child - 150 - 200 mcg. For children - 11 - 15 mcg. Below is a table with a list of chromium-rich foods.

Why is chromium needed in the human body?

Cr is literally irreplaceable for humans. It has no equal in the metabolism of proteins, cholesterol, and carbohydrates. Moreover, chromium is just as necessary for a woman’s body as it is for a man’s body.
Glucose metabolism: Cr is needed for efficient blood glucose metabolism. Proper consumption of the element leads to a decrease in the amount of insulin required to maintain optimal blood sugar levels. The connection of the element with insulin activates protein synthesis.
Cardiovascular system: Cr is active in fat metabolism, responsible for the concentration of cholesterol in the blood. It reduces both the overall level of bad cholesterol and increases the good one. Cr great value It also helps maintain normal blood pressure.

Why else does the body need chromium? And also:

• Cr is involved in the control of cardiac muscle function.
• Reduces cholesterol readings.
• Synthesizes nucleic acids and regulates the activity of the thyroid gland.
• Responsible for the concentration of sugar in the blood and stabilizes blood pressure.
• It stimulates the removal of harmful substances from the body.
• Strengthens bone tissue, prevents the development of osteoporosis.

Symptoms of chromium deficiency

Cr deficiency is the basis of the diabetic process, atherosclerosis and excess weight.

Signs of Cr deficiency in the body:

• desire to eat sweets,
• stable feeling of hunger,
• heavy sweating
• feeling of lethargy after sleep,
• dizziness.

In general, factors indicating a deficiency of a useful element do not accumulate immediately, but gradually. Very often, a person suffering from a deficiency of Cr does not immediately understand from his state of health that something is wrong with him. At first he feels some weakness, often sweats, and it seems to him that he is not getting enough sleep.
