What is Iodized Salt?
Iodized salt is a type of salt obtained by adding a certain amount of iodine to table salt. Iodine is a mineral with important functions in the body and is necessary for the production of thyroid hormones. To prevent iodine deficiency, iodine is commonly added to table salt in many countries.
The Role of Iodine in the Body
Iodine is vital for the proper functioning of the thyroid gland. The thyroid gland produces hormones called thyroxine (T4) and triiodothyronine (T3), which regulate metabolism. These hormones play essential roles in energy production, regulating body temperature, and overall growth and development. Iodine deficiency can negatively affect the production of these hormones, leading to various health problems.
Benefits of Iodized Salt
- Supports Thyroid Function: Iodine is necessary for the production of thyroid hormones. Sufficient iodine intake ensures the normal functioning of the thyroid gland and maintains hormone balance, helping regulate body metabolism.
- Supports Mental Development: Adequate iodine intake is crucial for mental development, especially in children. Iodine deficiency can lead to serious problems such as mental retardation and learning disabilities in children. Adequate iodine intake during pregnancy is also essential for the baby's brain development.
- Reduces Goiter Risk: Iodine deficiency can cause the thyroid gland to enlarge, leading to a condition called goiter. Consuming iodized salt helps prevent such thyroid gland enlargements.
- Supports Overall Health: Iodized salt supports immune system functions, increases energy levels, and improves overall health. Iodine also plays an important role in maintaining skin health.

Iodine Deficiency and Health Issues
Iodine deficiency is a widespread nutritional problem worldwide. People living in areas with low iodine content in drinking water and soil are at risk of iodine deficiency. Health problems that iodine deficiency can cause include:
- Goiter: Enlargement of the thyroid gland.
- Hypothyroidism: Low thyroid hormone levels, resulting in symptoms such as fatigue, weight gain, and cold intolerance.
- Mental Retardation: Mental and physical development retardation in children.
- Pregnancy Complications: Increased risk of miscarriage, stillbirth, and birth defects.

Usage of Iodized Salt
Iodized salt can be used as table salt in daily meals. However, proper storage is essential for iodized salt to maintain its effectiveness. Iodine can degrade over time due to light and moisture, so it is necessary to store iodized salt in a cool, dry, and dark place.
Iodized Salt and Global Health
Many countries promote the use of iodized salt to prevent iodine deficiency. International organizations such as the World Health Organization (WHO) and UNICEF support the use of iodized salt to reduce iodine deficiency globally. The widespread use of iodized salt has contributed significantly to reducing health problems related to iodine deficiency worldwide.
