Iodine in the human body: action, sources of iodine, symptoms of iodine deficiency


Iodine is an indispensable trace element in the human body, the synthesis of which is absent.It is iodine "responsible" for the normal functioning of the thyroid gland and the production of hormones.Iodine enters the body from the outside - with food and liquids, with some medicines.

Contents: How iodine is digested by the body How iodine deficiency in the body is manifested

According to statistics, the intake of iodine into the human body is as follows:

  • 60% - products of animal origin;
  • 3-5% - water;
  • 30% - products of plant origin;3-5% air.
  • .

The body of a healthy person has an amazing ability to keep a constant concentration of iodine in the blood.Iodine deficiency is detected quite often - about one in four of the examined patient. What you need to know about the optimal amount of iodine in the body:

  • for adults, the daily requirement for the microelement in question is 150-300 μg;
  • in childhood, the daily norm is 400 μg;
  • for pregnant and lactating women - 400 mcg;
  • with a pronounced lack of iodine in the body should come at least 400 micrograms of microelement per day.

How iodine is metabolized by the body

Jod Iodine is a trace element that belongs to the group of chemical compounds "halogens".The same group includes chlorine, bromine and fluorine, so the consumption of chlorinated water( it is just fed from the water system), treatment with drugs containing bromine and the intake of fluoride substances in the body reduces the amount of iodine.

Some products contain special substances that can block the reaction of iodine metabolism - they should not be combined with iodine-containing products.Such "problem" foods include rutabaga, cauliflower, radish, red cabbage, mustard, turnip.

Much better is the absorption of iodine, if simultaneously with it the body receives manganese, cobalt, copper, selenium.Doctors recommend eating foods that contain these trace elements, in combination with iodine-containing products.For example, will be an excellent solution to prepare a salad of sea kale and chicken eggs with selenium - the micronutrient in question will enter the body in the proper volume and be fully digested.

Often, with the appointment of a therapeutic treatment, doctors send a patient to a special examination that will show the level of iodine in the body.This is due to the fact that some drugs block the absorption of iodine - for example, Streptomycin, Erythromycin, Penicillin, Cordarone, Aspirin, some hormones, sulfanilamide group, Levomycetin.

Please note: if thermally treated products at high temperature, then 50% of iodine will be destroyed.Doctors recommend iodine-containing foods not to fry, but to boil or stew. Salt, enriched with iodine, should be added to the already prepared dish, then it will make sense.

shows a lack of iodine. Half of all iodine that has entered the body is absorbed by the thyroid gland, as this microelement is involved in the process of producing two hormones: thyroxine and triiodothyronine. These hormones ensure the normal functioning of the heart, organs of the gastrointestinal tract, brain, skin.Therefore, the lack of iodine in the body manifests itself almost immediately.

  • malaise and general weakness;
  • depressed mood;
  • frequent colds.

During this period, iodine deficiency is not yet at a dangerous level, because the body "scoops" this trace element from the thyroid gland.

  2. Obesity.Excess body weight appears due to a decrease in the rate of metabolic processes and a person gaining pounds of weight even when dieting.
  3. Mental disorders.With a lack of iodine, a person's memory worsens, concentration of attention decreases, problems with orientation in space can arise.Apathy and drowsiness.Such symptoms are clearly visible to others, they are often perceived as depression or banal fatigue.Meanwhile, drowsiness and apathy literally force a person to change their way of life.
