Eggs; tuna canned in oil and drained; cream-style corn; prunes; and cheddar cheese are also high in iodine, states the Office of Dietary Supplements. The amount of iodine found in fruits and vegetables depends largely on the iodine-richness of the soil where they were grown. Meat products contain iodine because iodine is added to animal feed, and iodophor is used as a sanitizer on dairy farms.

Iodine is necessary to make thyroid hormones, especially thyroxine and triiodothyronine, explains the Office of Dietary Supplements. These hormones regulate the production of proteins and the activity of enzymes. They also support the growth of the skeleton and central nervous system in fetuses and babies. Iodine might also support the immune system and guard against disorders such as fibrocystic breast disease.

Iodine is also found in multivitamins as sodium iodide and potassium iodide, notes the Office of Dietary Supplements. Potassium iodide and cuprous iodide have been added to salt in the United States since the 1920s. The Food and Nutrition Board recommend adults 19 years or older receive 150 micrograms of iodine every day. The recommended daily allowance is higher for women who are pregnant or nursing.
