The thyroid gland.

Explanation:

The thyroid gland requires iodine to function properly. In the United States iodized salt is used to ensure people intake adequate amounts of iodine in their diet.

When the thyroid gland has insufficient amounts of iodine the gland enlarges and forms a goiter.

Iodized salt was introduced in 1924 to reduce the goiter rate in the United States. Subsequent studies have also shown an increase in the IQ of people from areas of the world using iodized salt.
