Iodine is a mineral found in your body that aids with thyroid function and hormone production. It is also used to help convert food into energy. If you are on a low iodine diet, your doctor is likely trying to determine how much iodine your body is using. In most cases, this diet occurs prior to a test called a radioactive immunoassay. To obtain accurate test results, it is necessary to restrict your iodine intake prior to testing. The length of this diet, as well as dietary recommendations, may vary according to the prescribing physician.
Meats
It is permissible to eat small amounts of meat on a low iodine diet. Examples of allowable meats include beef, pork, turkey, lamb and chicken in amounts of about 5 oz. per day. Meats should be fresh and without injected broth. The meats you generally need to avoid are cured meats such as bacon, ham, sausage and hot dogs.
Starches
When it comes to bread, opt for homemade without salt. Avoid products that contain iodate conditioners, which are often present in commercially baked products such as breads, muffins and crackers. You may eat shredded wheat and oatmeal, but avoid instant hot cereals. In addition, you may have fresh peeled potatoes, homemade rice, and pasta made without salt and eggs.
Fruits and Vegetables
All fresh fruits and vegetables are acceptable on a low iodine diet. If you enjoy canned fruit, beware of varieties that contain red food dye, such as fruit cocktail. Vegetables that are canned or frozen are acceptable as long as they do not contain salt.
Beverages
Drinking coffee and tea is fine, but if you use cream, choose a non-dairy creamer. Carbonated beverages are also fine but once again, beware of red food dye. Beverages of which you should be particularly suspicious include red fruit drinks or punch. If you drink alcohol, your doctor will likely allow alcohol use in limited amounts.
Dietary Restrictions
The elimination of all seafood and dairy products is part of a low iodine diet, so avoid these foods completely. When it comes to salt, avoid iodized salt, sea salt, seasoned salt and salt substitute, but you may have non-iodized salt. Also, discuss medications you are taking with your doctor as some of these may contain iodine. Avoid additives, such as red food coloring, carrageen, agar-agar, algin and alginate, and do not eat out while on a low iodine diet. When preparing meals at home, use fresh foods and avoid packaged meals.
