Clinically, there is no such thing as “the side effect of eating rape while taking iodine 131”, and rape can be eaten during iodine 131 treatment. Serving iodine 131 is generally in the period of iodine 131 treatment, and at this time the patient’s diet should generally avoid eating iodine-rich foods, such as kelp, seaweed, a variety of seafood, etc., and rape does not belong to the iodine-rich foods, so it is possible to eat rape. Moreover, patients who need iodine 131 treatment are usually patients with hyperthyroidism or thyroid cancer. Hyperthyroidism will cause high metabolic state, while thyroid cancer will cause increased body consumption, both of which may be malnourished, but instead, they should increase the intake of food rich in vitamins such as oilseed rape, and they can also eat milk, eggs and other high-protein foods. Patients who need iodine 131 treatment should actively cooperate with their doctors.
