hi, I go in for RAI tomorrow. Were you told that you will definitely have to follow a low iodine diet? I was only told not to eat kelp by the radiologist and my endo said no added salt but no restrictions beyond that.
My Dr. also said that the low iodine diet wasn't necessary, but I did it anyway. The idea of this diet is to deplete any remaining thyroid tissue of iodine so that when you have RAI, the remaining cells will "suck it up". There is a lot of info about the diet and a LID cookbook on the Thyca web site. I found a few recipe's that I really liked. There was one called "wacky cake" that even my kids liked.
They recommend you follow it for 2 weeks before your treatment. I ended up having my treatment earlier than I expected, so I was only on it for 10 days. It was hard to stick to, but I made it.
Before undergoing radioactive scanning, your doctor may ask that you follow a low-iodine diet a week or two in advance. Your doctor may have a specific diet or timeline for you to follow. If not, these tips may help you stay on the right track. Of course, as with other aspects of your therapy, it's important to talk with your doctor about diet changes and other test preparation.
Some foods that contain iodine that you'll probably want to avoid are listed below:
Iodized salt, sea salt, and salty foods. Because it's hard to know which restaurants use iodized salt, you might want to avoid eating out during this time
All dairy products (milk, sour cream, cheese, cream, yogurt, butter, ice cream)
Seafood (fish, shellfish, seaweed, kelp)
Foods that contain carrageen, agar-agar, algin, or alginate - all of these are made from seaweed
Many prepared and/or cured meats (ham, bacon, sausage, corned beef, etc)
Fresh chicken or turkey with broth or additives injected
Commercial bakery products
Soy products (soy sauce, soy milk, tofu)
Any vitamins or supplements that contain iodine
FD&C red dye #3 - this appears in many foods or pills that are red or brown, including colas
