One of the most important micronutrients in the human body is iodine. The body contains about 25 mg of this trace element, 15 mg of which in the thyroid gland, with the remainder in the kidney, liver, prostate, ovaries, skin, nails and hair.

The daily requirement of iodine is equal to 50-200 mcg. He is involved in the formation of thyroid hormones, which are responsible for the development and growth of the organism, the efficiency of metabolic processes, generating heat. Athletes valued for the iodine that supports the function of the thyroid gland that contains hormones such as thyroxine and triiodothyronine – they are responsible for the increase in workout intensity, metabolism, and lower the percentage of fat in the body.


The lack of iodine in the body and its causes


Iodine deficiency is marked, almost two billion inhabitants of our planet. The deficit occurs when consumption of a micronutrient smaller on the daily rate, i.e. less than 0.05 mg.


According to research, during exercise the requirement of iodine increases.

The human body is unable to produce iodine, so the balance is always in need of replenishment with the help of external sources. They can be not only food, but the atmosphere, air and water.


For example, people who live far from the sea, the level of trace element in blood is lower than those who daily inhales saturated with iodine sea air.


Signs of iodine deficiency


Even the slightest lack of iodine in the body can provoke headaches, chronic fatigue, irritability, problems with memory and concentration.


To determine the body’s need for iodine, you need to perform simple manipulations:

  • A 5% solution of iodine onto the skin, apply a mesh of thin lines about 1cm frequency. In that case, if for 6-8 hours lines disappear – the body needs iodine.


What leads to the lack of iodine


  • Scientists have found that the amount of iodine is directly linked to the index IQ – so, deficiency of this mineral decreases IQ by 10-15 points.
  • Deficiency may lead to slowing of metabolism and as a consequence the acceleration of the weight gain.
  • For pregnant women, iodine deficiency is fraught with anomalies in the development of the fetus and miscarriage.
  • Children suffering from iodine deficiency, are lagging behind in mental and physical development, and their nervous system is poorly developed.


Iodine deficiency and obesity


When iodine deficiency the body begins to experience difficulties with the use of glucose as energy in order to avoid such difficulties, he is forced to increase the percentage of its processing fat.


Low levels of T3 and T4 hormones affects reactions of the human body, making it sluggish, which contributes to obesity.


The lack of iodine in the body is directly associated with HGH levels. Low growth hormone not only allows you to gain muscle mass, but also strongly inhibits the process of burning fat.


Excess iodine in the body


An overabundance of trace element occurs exclusively in cases of abuse of iodine, which is the uncontrolled methods of iodine-containing vitamins and food supplements, or the work associated with its production.


The high content of iodine in the body is able to suppress the production of thyroxine. Synthesis of iodine compounds in the thyroid gland is weakened due to excess iodine, and as a consequence leads to hypothyroidism.


Replenish iodine in the body should not get involved. For example, a single dose of iodine equal to 3 g can result in death.


Panic attacks and paranoia due to excess iodine


The thyroid gland is a shield, not only on the physiological level, but also helps to combat stressful situations. For its proper functioning is necessary to maintain the recommended balance of iodine.


In cases of non-compliance balance, the thyroid gland begins to falter in the work, leading to the development of such mental symptoms, such as paranoia or panic attacks.


The delicate balance of the human systems that ensure its resistance to stressful situations, depends, among other things, the amount of iodine in the body.

After consultation with a doctor, ultrasound and mandatory tests for blood, a deficiency of iodine in the body can be filled by appointment by a consultant endocrinologist preparations containing salts of iodine, for example, “Iodide”, “codomain”, “Godin”, “Yod-asset”. The course may last from several months to 2 years.

Prepare your diet to present products that contains daily rate of iodine, specifically 150-200mkg. That is, saturate the diet of marine fish species, seafood, dairy products, eggs, cereals such as buckwheat and millet, seaweed, iodized salt.

Consultation with a doctor who is able to diagnose the excess of iodine, based on medical history, clinical picture, to determine the level of iodine in blood and urine. Then, following prescribed treatment, eliminated the mechanisms of iodine in the body alongside with treatment therapy is aimed at correction of the thyroid gland

The diet is based on eating foods with a complete lack of iodine or with its minimal content


Foods containing iodine:

In products, is more typical modern diet, such as cereals, milk, eggs, oil level iodine content is extremely low. Most of us live in the atmosphere is not rich in iodine. It is therefore important to care for and maintain the balance of iodine in the body.published econet.ru.
