Natural Food Sources of Iodine

Iodine is an essential trace element naturally found in the body. Iodine is vital for the proper functioning of the thyroid gland and its production of the hormone thyroxin. Thyroxin is crucial for the physiological functions of metabolism, reproduction and growth and development. Characteristic signs of iodine deficiency include low energy level, weight gain and goiter (an enlarged thyroid gland). Iodine is normally obtained from foods.

Iodized Salt

Most of the iodine consumed in a daily diet is obtained from iodized salt–a rich inexpensive source of iodine. According to the United Nations University, salt is iodized by adding fixed amounts of potassium iodide or iodate in a dry solid or aqueous solution. Salt functions as an excellent medium for iodine and a cost-effective way to add iodine to the daily diet. One teaspoon of iodized salt provides 400mcgs of iodine, according to Northwestern University. The recommended dietary allowance (RDA) of iodine for people age 14 years and older is 150mcg daily. Seventy to eighty percent of the body’s iodine is stored in the thyroid gland, and portions are released as needed.
