01/10/2021 · Radioactive iodine (often abbreviated RAI) is a therapy used to treat hyperthyroidism and thyroid cancer. In this procedure, you are intentionally given Iodide, I131, which emits radiation. Your body then takes up this radioactive iodine into your thyroid gland where the radiation proceeds to destroy thyroid gland tissue.
Objective: Consuming a lowiodine diet (LID) is a widely accepted practice before administering radioiodine (131I) to evaluate and to treat thyroid disease. Although this procedure is well established for the management of patients with differentiated thyroid cancer, its use in patients with benign disease is unclear.
Patients are placed on a lowiodine diet two weeks prior to receiving radioactive iodine. This makes them iodinedeficient and increases the chance that the thyroid cells will absorb the radioactive iodine dose. Increase the TSH level A high thyroidstimulating hormone (TSH) level increases the ability of thyroid cells to absorb iodine.
To provide a diet low in iodine (<50µg/day) to promote maximal uptake of radioiodine (131I) for diagnosis and/or treatment of thyroid cancer. Characteristics Severely reduces iodine derived from food, avoids soy foods (due to the potential for interaction with radioiodine uptake), and avoids the following additives:
01/10/2010 · The most commonly studied diets allowed ≤50 μg/day of iodine for 1–2 weeks. In one study, 6month successful remnant ablation rates were higher in patients following an LID than in controls. However, in another study, there was no significant benefit of an LID.
There is no discomfort. You can eat beginning about 1 to 2 hours after swallowing the radioactive iodine. You can go back to a normal diet after the test. Why the Test is Performed This test is done to check thyroid function. It is often done when blood tests of thyroid function show that you may have an overactive thyroid gland. Normal Results

A lowiodine diet was developed for used in decreasing iodine intake and excretion in patients undergoing evaluation with radioactive I131 for ablation of thyroid remnants as treatment for thyroid cancer. It has been demonstrated to effectively lower iodine excretion to .
Patients receiving radioactive iodine should avoid Close contact (< 3 feet) with young children, elderly, and pregnant women Sharing a toilet or bathroom. Flush with the lid down. Sharing food. Sharing a bed. Kissing and ual activity. All clothes, towels, and linens should be washed separately. Wash hands and the rest of the body often.
In order for the treatment to be successful, the thyroid tissue must absorb the radioactive iodine instead of normal iodine. The lowiodine diet reduces the amount of normal iodine in the body, thereby avoiding competition for absorption between the regular iodine from food and the administered radioactive iodine.
18/07/2020 · High iodine foods which should be avoided – Fish, seafood, seaweed, kelp, laverbread – Dairy produce such as milk, butter, margarine, cheese, yoghurt, icecream etc – Egg and foods that contain egg yolk – for example custard, mayonnaise – Fresh egg, egg fired rice – Milky coffee and tea, cappuccino, hot chocolate, malted milk drinks

· Toast with nondairy spread and marmalade, jam, honey, marmite · Porridge made with water or milk substitute, topped with fruit, honey or syrup · Fresh fruit or fruit salad or Grapefruit cocktail · Cooked breakfast (without eggs) such as bacon, sausages, tomatoes, mushrooms, hash browns, baked beans, toast Lunch
You may be placed on a lowiodine diet for 2 to 3 weeks before the procedure. You will need to avoid: Foods that contain iodized salt Dairy products, eggs Seafood and seaweed Soybeans or soycontaining products Foods colored with red dye You may receive injections of thyroidstimulating hormone to increase the uptake of iodine by thyroid cells.
Also rich in iodine and to be avoided are foods like sea salt, seaweeds and sea vegetables, seafood, red dye #3, packaged baked goods, egg yolks and whole eggs, chocolate, potato skins, beans, soybeans, and soy products, and all dairy products.
