Iodine is a nutrient that is necessary for the metabolism in cells. According to MedlinePlus, most people obtain iodine in their diet from iodized salt or foods seasoned with iodized salt. Sometimes, people may need to avoid iodine because of a medical condition. Some foods are lower in iodine than others and are safe to eat on a low-iodine diet.
Proteins
Fresh, non-cured and preferably organic beef, pork or chicken are generally safe to eat on a low-iodine diet, according to the Thyroid Cancer Survivors' Association. However, check the ingredients in packaged meats carefully for additives, as some of them can contain iodine. Unsalted nuts and nut butters are also low in iodine, but check the ingredients list for any additives. Seafood, egg yolks and salted or cured meats contain high amounts of iodine and should be avoided.
Fruits and Vegetables
Most fresh fruits and vegetables are low in iodine, although spinach and broccoli should be eaten in moderation. Use caution with canned or frozen vegetables as they may have added salt or other additives that contain iodine. According to ThyroidCommunity, a website run by Genzyme, maraschino cherries and fruit salads containing maraschino cherries should be avoided because they contain E 127 Erythrosine, also known was Red No. 3, a dye that contains iodine.
Other Foods
Breads prepared at home with non-iodized salt and no dairy products are considered safe to eat on a low iodine diet, according to ThyroidCommunity. Coffee and tea made with distilled water are also safe for consumption, as are clear sodas. Colored sodas and other beverages should be avoided because they may contain Red No. 3.
Foods to Avoid
Soybeans and any products containing soy derivatives should be avoided because they contain iodine. This includes soy sauce, soy milk and tofu. Avoid dairy products such as milk, yogurt, cheese and butter and any foods containing dairy products. Check labels for any foods or dietary supplements and avoid any that contain Red No. 3.
