Introducing Iodine

Iodine, essential mineral, nourish notesThe body does not make iodine, so it is an essential part of your diet. In addition, this mineral  is needed for the production of thyroid hormones. As an integral part of thyroid hormones it regulates body temperature, metabolic rate, reproduction, growth, blood cell production, nerve and muscle function and more. By controlling the rate at which the cells use oxygen, these hormones influence the amount of energy released when the body is at total rest. Approximately 70 to 80% of the body’s iodine is found in the thyroid.

The Primary Sources of Iodine

Most foods have low iodine content however, iodized salt, seafood, plants grown in iodine-rich soil and animals fed those plants or feed containing iodine are good sources. Additional foods may be sources of iodine if iodized salt is used in their preparation (e.g. bread).

Bioavailability of Iodine

Normally, the absorption of iodine from foods is very high (>90%). Some foods (e.g., cassava, millet, lima beans, cabbage) contain substances called goitrogens. These substances inhibit the transfer of iodine to the thyroid gland and disrupt the production of thyroid hormones. If foods containing goitrogens are consumed in large quantities, they may limit the absorption and use of iodine by the body. In general, most people can tolerate higher intakes of iodine from food and supplements.


Risks Related to Inadequate Intake of Iodine

Iodine deficiency has adverse effects at all stages of development but is most damaging to the developing brain. In addition to regulating many aspects of growth and development, thyroid hormone is important for myelination of the nerves, which is most active before and shortly after birth. Thus during pregnancy, diets deficient in iodine may result in higher risk for mental retardation. Thyroid enlargement, or goiter, is one of the most visible signs of iodine deficiency.
