Iodine is an essential nutrient required for the synthesis of thyroid hormones, and its deficiency can lead to thyroid disorders, such as goiter, hypothyroidism, and cretinism. Therefore, it is necessary to consume an adequate amount of iodine-rich foods or iodine supplements to maintain the proper functioning of the thyroid gland and prevent such disorders.
