What does iodinated mean?
“Iodinated” means containing iodine or having been treated with iodine. The word is especially familiar from “iodinated salt,” which has iodine added so that it can help prevent dietary iodine deficiency, a condition associated with thyroid problems. In medicine, an iodinated substance may contain iodine in a form used for imaging, such as an iodinated contrast agent. The term is also used more broadly for substances to which iodine has been added. “Iodinated” is precise and common in technical and nutritional contexts, while “iodized” is often the more natural everyday term in American food labeling. The word’s importance is practical as well as linguistic: iodine is an essential trace element, but its intake depends partly on diet and public-health measures.
