What is idinoized salt?

Iodized salt is table salt that has been fortified with iodine, an essential nutrient that helps prevent iodine deficiency and related health issues, such as goiter and thyroid problems. Iodine is crucial for the production of thyroid hormones, which regulate metabolism and growth. The addition of iodine to salt was introduced in the 1920s to combat widespread iodine deficiency in various populations. It is commonly used in cooking and food preparation to ensure adequate iodine intake.
