- A low-iodine diet depletes the body's storage of iodine. The purpose of this process is to boost the effectiveness of radioactive treatments to fight thyroid cancer. During the treatment, the body will absorb iodine better because the body has been so depleted of iodine.
While using the low-iodine diet, consume no more then 50 micrograms of iodine per day, according to the American Thyroid Association. A single teaspoon of iodized salt contains 400 micrograms of iodine, so watch iodized salt consumption closely. - Foods to avoid that are high in iodine include fish, dairy products, egg yolks, store-bought bakery products, and chocolate. Also, avoid soybeans, kidney beans and potato skins. Vitamin supplements that contain iodine should also be avoided. Before going on a low-iodine diet, always talk with your doctor.
- Even if you are not getting radiation, some diet changes can help your recovery efforts. Cruciferous vegetables are full of carotenoids, fiber and folate, which may be anti-cancer properties, according to the Mayo Clinic. When eating these vegetables, make sure not to overcook, which destroys the anti-cancer properties.
Also, stock up on grapes, which are rich in proanthocyanidins and resveratrol. These nutrients can block free radicals, which damage healthy cells. Studies in animals have also shown that omega-3 fatty acids may inhibit tumor growth.
