Hypothyroidism Can Be Caused by a Dietary Deficiency in ____

Question

Hypothyroidism can be caused by a dietary deficiency in ____.  
A) vitamin D
B) multivitamins
C) Penicillin
D) thyroxin
E) iodine

Accepted Answer

Hypothyroidism can be caused by a deficiency in iodine, which is an essential nutrient for the production of thyroid hormones. Without sufficient iodine, the thyroid gland cannot produce enough hormones to regulate metabolism, leading to the symptoms of hypothyroidism. Vitamin D, multivitamins, and penicillin do not play a direct role in thyroid function, while thyroxin is a medication used to treat hypothyroidism but is not a dietary nutrient.
