Which statement best describes why iodized salt is recommended for thyroid health?

• A. Can prevent the development of goiter in adults and cretinism in infants.
• B. Can help prevent hypothyroidism.
• C. Is instrumental in preventing tumors of the parathyroid gland.
• D. Works as an important component of thyroid replacement therapy.

Answer: (A)

Iodine is essential for making thyroid hormones T3 and T4. When iodine is insufficient, the thyroid can’t produce enough hormones, so the pituitary releases more TSH to stimulate the gland, leading to goiter in adults. In pregnancy and infancy, iodine deficiency can cause cretinism, a preventable form of severe neurodevelopmental impairment. Providing iodine through iodized salt helps ensure adequate intake, reducing the risk of both goiter and cretinism. It’s not a replacement therapy for thyroid disease, and it doesn’t address conditions like parathyroid tumors.
