Which mineral is sourced from seafood and iodized salt?

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

Answer: (D)

Iodine is essential for the production of thyroid hormones, which regulate metabolism, growth, and development. It is predominantly found in seafood and iodized salt, as these sources have been specifically fortified or naturally contain iodine. The inclusion of iodine in table salt was introduced to prevent disorders caused by iodine deficiency, such as goiter and other thyroid-related problems. This practice has significantly improved public health and maintained adequate iodine levels in populations where dietary sources may be lacking. In contrast, iron is primarily found in meats, beans, and some leafy greens; zinc is sourced from animal products, nuts, and seeds; while fluoride is commonly added to dental products and found in certain water supplies, but not sourced from seafood or iodized salt, which differentiates iodine as the correct mineral in this context.
