There wasn't that much Iodine in food, even then, and certainly not enough to interfere with any tests using radio-iodine. Even if there were, it wouldn't justify removing it from the food supply just for those very very few individuals who might need a radio-iodine contrast. But removing it, and replacing it with bromide, and flourides... well, we're witnessing the train wreck from that shitt, a plot to create a national health care problem, and then voila, the solution !! bwahahaha!!
