Low Iodine Diet
Low Iodine Diet Preparation for Radioactive Iodine
• This is a low-iodine diet, not a no-iodine diet or an iodine-free diet.
• Remain on this diet for two weeks (7-14 days) before you have a radioactive iodine scan or a radioactive iodine treatment.
• It is important to continue all of your current medications as directed by your doctor, even if the medication contains small amounts of iodine.
• You may eat foods that are low in iodine (up to 5 mcg per serving); limit your intake of foods that have a moderate level of iodine (5 to 20 mcg per serving); and avoid foods high in iodine (over 20 mcg per serving).
• Read the ingredients listed on packaged food labels. Consider using this low iodine cookbook.
Because some restaurants use iodized salt and there is no way to determine which do, avoid all restaurant food. You may eat foods that contain small amounts of milk or egg. You may use non-iodized salt. Consult your doctor before discontinuing any red-colored medication.
