Why can thyroid cancer (total resection) eat normally?
Because iodine is the "raw material" for synthesizing thyroid hormone, thyroid is the "factory" for synthesizing thyroid hormone. The "factory" no longer exists, and no amount of "raw material" (iodine) can produce thyroid hormone. Therefore, after total thyroidectomy, there is almost no demand for iodine, and there is no need to deliberately ingest iodine-containing food.
However, there is no need to deliberately exclude foods containing iodine. After complete thyroidectomy, the iodine ingested by the human body is absorbed into the blood by the small intestine, which cannot be used and stored, and the excess iodine will be excreted by the kidney.
