The Elements: Iodine

Iodine is a chemical element that appears to glitter and emits a purple color when heated. It is widely used in medicine for sterilization, treating radiation sickness, and as a contrast agent in imaging. Iodine is crucial in our diet, particularly found in dairy and seafood, and is essential for thyroid hormone production. Iodine deficiency affects billions globally, leading to health issues, and is often supplemented in table salt. A balanced diet typically provides sufficient iodine.
