The World Iodine Deficiency Day is celebrated annually on October 21. This day is dedicated to raising awareness about the problem of iodine deficiency — one of the most important trace elements necessary for the normal functioning of the body.

History of the holiday
The holiday was established by the World Health Organization (WHO), the United Nations Children’s Fund (UNICEF), and the International Council for the Control of Iodine Deficiency Disorders (ICCIDD). The goal was to draw public and governmental attention in various countries to the consequences of iodine deficiency in nutrition and the need for preventive measures.

For a long time, iodine deficiency was one of the most common causes of mental and physical developmental disorders in children around the world. Thanks to salt iodization programs, the situation has improved significantly, but the problem remains relevant in many regions.

Causes and consequences of iodine deficiency
A lack of iodine in the body can cause serious health problems:

* enlargement of the thyroid gland (goiter);
* mental retardation and developmental delay in children;
* decreased performance and metabolic disorders in adults;
* complications during pregnancy and childbirth.

Iodine is essential for the production of thyroid hormones, which regulate metabolism and the development of the nervous system.

Traditions and events
In different countries, events aimed at preventing iodine deficiency are held on October 21:

* public awareness campaigns on the importance of consuming iodized salt;
* lectures, seminars, and educational programs in schools and medical institutions;
* free thyroid screenings and endocrinologist consultations;
* publication of scientific data and reports on the iodine status of populations.

Significance of the holiday
The World Iodine Deficiency Day reminds us that even simple measures, such as adding iodine to salt or eating seafood, can prevent serious diseases and improve the quality of life for millions of people.

Interesting facts

* According to WHO, thanks to salt iodization programs, more than 70% of the world’s population is now protected from iodine deficiency.
* Natural sources of iodine include sea fish, seaweed, shrimp, eggs, and dairy products.
* Iodine deficiency is more common in mountainous areas and regions far from the sea.
