The short-term low-iodine diet is another part of preparing to receive radioactive iodine for papillary or follicular thyroid cancer or one of their variants. The diet, recommended by ThyCa Medical Advisors, other thyroid cancer experts, and the American Thyroid Association, increases the effectiveness of the radioactive iodine treatment. Note that sodium is not an issue. What is to be avoided is the added iodine found in iodized salt, which is widely used, especially in processed foods. This does not apply to foods that naturally contain sodium without salt as an ingredient. There are many foods you can eat while on the low-iodine diet. It is a good idea to cook meals yourself, using fresh ingredients, including fruits, vegetables, and unprocessed meats. Many thyroid cancer patients with papillary or follicular thyroid cancer receive a dose of radioactive iodine RAI about two months after their surgery in an attempt to destroy ablate any remaining thyroid cells in their bodies. The diet is to prepare for the RAI.
The thyroid gland is made up of a special type of cell that absorbs the iodine circulating in the body and uses it to produce thyroid hormones. Radioactive iodine uptake scans take advantage of this quality of thyroid cells and use a type of labeled iodine to pinpoint any remaining thyroid tissue in the body. These scans can be used to identify residual thyroid tissue after surgical removal of the thyroid, or cancerous tissue that has metastasized, or spread, to other organs. Radioactive iodine can also be used in larger doses as a treatment, as the radiation will ablate, or destroy, any remaining thyroid tissue RAI treatment. Before a patient undergoes either a radioactive iodine uptake scan or a radioactive iodine treatment, they will be put on a low iodine diet. This page will explain why the diet is important, how it works, and how best to adhere to the diet. Iodine is found in the soil and in almost everything we eat, especially dairy products and seafood. Iodine can also come from chicken and cattle that have been fed with iron-supplemented feed. Prior to any form of radioactive iodine scan or treatment, patients should be placed on a low iodine diet. This diet deprives the body of iodine, and makes radio-iodine uptake more effective. When the body senses low iodine levels, the pituitary gland in the brain releases TSH thyroid stimulating hormone, which stimulates the thyroid cells to absorb more iodine. This diet helps to ensure that the thyroid cells will uptake the radioactive iodine that is administered for the scan or treatment, rather than any normal iodine that may be circulating in the body.
Looking for Low Iodine Recipes? Salad dressings provided they contain only allowed ingredients. What could we have explained better? The following foods and ingredients are fine to eat. The reason why people should be careful with celery is because large amounts of celery can interfere with iodine uptake and can result in a goiter enlarged thyroid. It is not a substitute for professional advice or help and should not be relied on to make decisions of any kind. Clinicians also often recommend that the low iodine diet be continued for days after radioactive iodine therapy. Use the cookbook’s lists and tips.
