Might not be enough with the invasion of bromide, floride and chloride.
All will cancel out/compete with iodine...

the problem is more serious than just food can fix. the problem is the decades of poisoning with the other halides while Iodine in the diet was non-existent. it is called halide imbalance syndrome, and it should be supplemented away, then one can avoid the other halides best they can and get the Iodine in food. if you just go with food, it will take a lifetime to reverse, if ever. especially if you dont know to avoid the other halides.
