Quizplus · Accepted Answer

Goiter is most often associated with a deficiency of iodine, which is necessary for the production of thyroid hormones. Without enough iodine, the thyroid gland enlarges as it tries to produce more hormones, leading to a goiter. Iron deficiency can lead to anemia, protein deficiency can lead to muscle wasting, and vitamin A deficiency can lead to night blindness and other vision problems, but they are not directly associated with goiter.
