You need good nutrition right now. Eat a well-balanced diet. And, personally, I think it helps in the long run to avoid “empty” calories: any food that does not provide nutrition, or much nutrition, but has a high calorie load. There will be some sites online that will tell you to avoid certain veggies that contain a chemical thought to cause goiter (enlarged thyroids). But it is physically impossible for a human being to eat enough of these foods to make any difference whatsoever. And these foods have good nutrition in them, so avoiding them isn’t wise.
Do NOT take kelp supplements: the iodine content in these supplements is extremely high, and it can throw your thyroid cell function off in unpredictable ways. As a result of this recommendation by my endo, I also avoided sushi that was wrapped in seaweed (kelp), but I don’t know if that was necessary or not.
Prior to RAI, or an uptake and scan test, you will be told by your doctors to avoid seafood/shellfish of certain types for a period of time. Seafood typically contains more iodine than other foods, and for the purpose of the test, or treatment form of RAI, you want your thyroid cells to have room to take in the required medication. This restriction is only a temporary measure. You need some iodine in your diet for a healthy body (unless you completely remove every bit of your thyroid), and you cannot control your graves by trying to eliminate iodine.
