you absolutely can be allergic to iodine! true that most people who are allergic to seafood are allergic to the proteins within but some people as myself have a true reaction to high levels of iodine and it can buildup to a reaction by consuming iodine-rich foods consecutively. yes we need a small amt of iodine for our thyroid to work but people with a true allergy to iodine have to take in the bare minimum and live with daily itching.
no allergy to shellfish. ct scan w/contrast-mild reaction of hives. would there be allergic reaction to shell fish now?
