Quizplus · Accepted Answer

Goiter is most often associated with a deficiency of iodine, which is an essential mineral needed for the production of thyroid hormones. Without enough iodine, the thyroid gland enlarges in an attempt to produce more hormones, resulting in a goiter. Iron deficiency may cause anemia, protein deficiency may lead to malnutrition, and vitamin A deficiency may cause vision problems or other health issues, but none of these are directly linked to goiter.
