Why is it added to salt and is it necessary to draw an iodine grid?

Iodine deficiency can be compensated for by diet

Mild iodine deficiency is common in Russia, which is caused by a lack of this microelement in food, especially in regions where seafood is unavailable. The main source of iodine is seafood, such as fish, seaweed and shellfish. However, due to limited access to fresh seafood, especially in remote or rural areas, it can be difficult to fully cover iodine needs through diet. Therefore, adding iodine to everyday food, for example, to salt, becomes an important step in preventing iodine deficiency at the level of the entire population.

Is there an allergy to iodine?

Iodine, as an element, has a very low molecular weight, and allergic reactions to it in the traditional sense are extremely rare. The main problems associated with iodine usually concern overdose. Under normal conditions and when used correctly, the risk of iodine overdose is low. Iodine is vital for the normal functioning of the thyroid gland, metabolism, and other important physiological processes. Therefore, the problem is not in allergies, but in a possible overdose or dosage violation.

Iodine grid helps to resolve swelling and bumps from injections

Iodine grid, as a method, has no official medical recommendations and proven effectiveness. Although you can often find recommendations to draw an iodine grid to relieve symptoms such as swelling or bumps, scientific research does not confirm its healing properties. Iodine grid may not have a significant therapeutic effect and is not a substitute for medical treatment. It does not cause harm, but does not have a serious effect on reducing swelling or bumps.

If iodine is rapidly absorbed through the skin, then there is iodine deficiency

Assessment of iodine levels in the body to diagnose deficiency is usually done by urine testing at the population level rather than in an individual. Determining iodine levels by measuring iodine absorption through the skin is not a reliable method for diagnosing deficiency. Urinary iodine concentrations provide a more accurate indication of iodine levels in the body and are used to determine deficiency at the population level.
