Dietary Iodine

Dietary iodine is a mineral essential for the production of thyroid hormones, which regulate metabolism, growth, and development. Since the body cannot produce iodine on its own, it must be obtained through food and water. Common sources include seafood, dairy products, eggs, grains, and iodized salt. Adequate iodine intake is vital, especially during pregnancy and childhood, to support healthy brain development and prevent disorders like goiter (enlargement of the thyroid gland). Too little iodine can lead to hypothyroidism and developmental issues, while excessive intake may cause thyroid dysfunction. Maintaining balanced iodine consumption is important for overall health.
