my husband has graves and his doctor has a list of things that are high in iodine to avoid. believe it or not…milk products. the industry standard is to clean the utters and machinery with iodine. also, no sea salt or seaweed. you can use kosher salt instead. there are a lot of vegetables that contain high amounts of iodine also such as aspargus, broccoli, white onion, corn, brussel sprouts. also, potato skin contains high amounts of this as well. be careful with seafood products, such as, squid, crab, sole. there are many others if you look on the cdc’s website for vegetable and fruit nutirition guidelines. i am not a doctor so the best thing would be to talk directly with yours to come up with a plan that works best for you. also, everything in moderation after your levels are in normal range is a good way to look at it. i hope i helped a bit.
