Avoid These Foods and Additives
Avoid the following foods, starting when instructed before your radioactive iodine test or treatment, and continue as instructed until after your radioactive iodine treatment is completed. These foods and ingredients are high in iodine (over 20 mcg per serving, according to researchers' presentations at our conferences).

•   Iodized salt and sea salt and any foods containing iodized salt or sea salt. Non-iodized salt (such as Kosher salt unless the label says that it is iodized or sea salt) may be used. The reason to avoid sea salt is that all products from the ocean tend to be high in iodine.You can usually find plain, non-iodized salt next to the iodized salt at your grocer.

•   Seafood and sea products (fish, shellfish, seaweed, seaweed tablets, kelp). These are all very high in iodine and should be avoided.

•   Dairy products (milk, cheese, cream, yogurt, butter, ice cream, powdered dairy creamers, other dairy products). Although the source of the iodine is not known, tests of all types of dairy products have generally shown the presence of iodine, sometimes in very large quantities. Animals secrete dietary iodine into their milk, animal feeds often contain iodine, and products containing iodine may be used to clean udders. Also, methods for processing dairy products can change over time and from one company to another. Note: Nondairy creamers often have iodine-containing ingredients, too.

•   Egg yolks or whole eggs or foods containing whole eggs. (Egg whites are acceptable, because they do not contain iodine).

•   Foods or products that contain these additives: carrageen, agar-agar, algin, alginate, nori (these are food additives that are seaweed by-products).

•   Commercial bakery products. Avoid bread products that contain iodine/iodate dough conditioners (usually small bakery breads are safe; it’s best to bake it yourself or substitute with Matzos). If you read labels closely, you may also be able to find crackers made only with flour and water. While a few commercial bakery products have tested low in iodine, manufacturing processes can change over time.

•   Red Dye #3. However, Red Dye #40 is OK. We suggest that you avoid red, orange, or brown processed food, pills, and capsules. Many red, red-orange, and brown food dyes contain iodine and should be avoided. The problem with food colors is specific to Red Dye FD&C #3 (erythrosine) ONLY. However, the problem is that some food labels do not specify which red dyes are used. Better safe than sorry. For medications, the best source is the Physician’s Desk Reference (PDR), which clearly states the ingredients. For example, Rocaltrol in the 0.5 mcg size is NOT good for the diet because it contains FD&C Red Dye # 3. However, Rocaltrol 0.25 mcg does not and is safe for the diet (you can take two of them to get to the 0.5 mcg dose). Please always check with your physician.

Avoid These Foods and Additives—continued from the previous page.

•   Chocolate (for its milk content). Cocoa powder and some dark chocolates are permitted. Check the label for other ingredients not allowed on the low-iodine diet.

•   Molasses (sulfured, such as blackstrap molasses, which has a slightly bitter taste. It's okay to use the milder, fairly sweet unsulfured molasses usually used in cooking.)

•   Soy products (soy sauce, soy milk, tofu). These vary in iodine content. Some are moderate in iodine. (Some diets say that vegetable oil with soy is okay.)

•   Some beans – The National Institutes of Health diet says to avoid these beans:

red kidney beans, lima beans, navy beans, pinto beans, and cowpeas.

•   Potato skins. These have iodine. The inside of the potato is fine.

•   Rhubarb.

•   Iodine-Containing Vitamins, and Food Supplements. Also products containing iodate or iodide. Check the label and ingredients and discontinue completely if iodine is included. Most vitamins with minerals contain iodine. Vicon Forte, a multivitamin, is fine for the diet.

•   If you are taking a Medication that contains iodine, check with your physician.
