Iodides are chemical compounds that contain iodine, a vital element for human health. They typically form when iodine combines with another element, such as sodium or potassium. Iodides are important in various applications, including medicine, where they are used in antiseptics and imaging procedures. In nature, iodides can be found in certain foods, particularly in seafood and dairy products. The body needs iodine to produce thyroid hormones, which regulate metabolism. A deficiency in iodine can lead to health issues, such as goiter or thyroid problems, making iodides essential for maintaining overall well-being.
