The thyroid gland is dependent on dietary iodine for the production of thyroid hormones, normal iodine requirement being about 150-200μg/day. Long-term deficiency in iodine intake is associated with the development of goiter. When the prevalence of goiter in a population rises above 5-10%, the problem is considered endemic …
