Final answer:
Inadequate iodine in the diet can lead to various disorders, including hypothyroidism, myxedema, high TSH levels, and cretinism. Iodine is crucial for the production of thyroid hormones, and its deficiency can result in impaired growth and development, as well as intellectual disabilities.
Step-by-step explanation:
Inadequate iodine in the diet may lead to hypothyroidism, myxedema, high blood levels of TSH, and cretinism. When there is a deficiency of iodine, the thyroid gland is unable to produce enough T3 and T4 hormones. This results in a variety of disorders, including goiter (enlarged thyroid gland) and impaired growth and development. Additionally, iodine deficiency is the primary cause of preventable intellectual disabilities worldwide.
