                                According to the American Thyroid Association, a low-iodine diet, often referred to as a RAI complexity diet, is a temporary, short-term dietary restriction followed by patients undergoing radioactive iodine (RAI) therapy for thyroid cancer.  This diet is crucial for preparing the body for treatment by depleting iodine stores, which makes thyroid cells more receptive to the radioactive iodine.
