some table salt sold for consumption contains additives which address a variety of health concerns, especially in the developing world. the identities and amounts of additives vary widely from country to country. iodine is an important micronutrient for humans, and a deficiency of the element can cause lowered production of thyroxine (hypothyroidism) and enlargement of the thyroid gland (endemic goitre) in adults or cretinism in children. iodized salt has been used to correct these conditions since 1924 and consists of table salt mixed with a minute amount of potassium iodide, sodium iodide or sodium iodate. a small amount of dextrose may also be added to stabilize the iodine. iodine deficiency affects about two billion people around the world and is the leading preventable cause of mental retardation. iodized table salt has significantly reduced disorders of iodine deficiency in countries where it is used.
