Additives in table salt

Most table salt sold for consumption contain 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 and iodide. Iodine is important to prevent the insufficient production of thyroid hormones (hypothyroidism), which can cause goiter, cretinism in children, and myxedema in adults. Iodine-containing compounds are added to table salt. Iodized salt is thus table salt mixed with a minute amount of potassium iodide, sodium iodide, or sodium iodate.

• Fluoride

• Anti-caking agents

• Iron
