Goiter is most commonly linked to an imbalance of which nutrient?

Goiter is most commonly linked to an imbalance of which nutrient?

• A. Vitamin C
• B. Iodine
• C. Iron
• D. Fluoride

Answer: (B)

Iodine is essential for making thyroid hormones. When iodine intake is low, the thyroid can’t produce enough T3 and T4, so the pituitary releases more TSH to stimulate the gland. That increased stimulation causes thyroid growth, leading to a goiter. This is particularly common in areas with iodine-deficient diets, and iodized salt has dramatically reduced goiter prevalence. The other nutrients listed aren’t directly involved in thyroid hormone production or gland enlargement, so they aren’t linked to goiter.
