Low Iodine Diet FAQs

Iodine in Food?

Iodine is found in food.  In some foods, it is naturally there from the soil,  including plant based foods as well as animal foods (meat) since that animal ate the plants. Iodine can also be added to food as a supplement or via residues from disinfectants on equipment. (1)

How Does My Body Use Iodine?

Iodine is used by the thyroid gland for making thyroid hormones.  Thyroid hormones have MANY functions in your body and can influence every cell in your body.  These include:

  • Effects your metabolism, including how your body burns calories – this affects your weight as well as your energy levels
  • Regulating your heartbeat
  • Regulating body temperature
  • Can affect digestion speed – meaning too much can cause diarrhea, too little constipation

Why do I Need a Low Iodine Diet?

A low iodine diet (LID) is used before radioactive iodine treatment to make the body “iodine hungry”. (1) The basic idea is if you deprive your body of iodine, any remaining thyroid cells (specifically thyroid cancer cells) will be very hungry and aggressively take up the radioactive iodine when you receive treatment.  This should make the treatment more effective.

How do I know if Iodine is in a Food?

There is not really a great way to know the iodine content of food.  Iodine is not required on nutrition labels and is not regularly measured in whole foods.

Most processed foods in the United States do NOT contain iodized salt.  However, manufacturers are NOT required to state on the label if they use iodized salt or not.  LIDLife has extensive lists of manufacturers they have contacted about what salt they use.

I have contacted some manufacturers, including for any items on this list.  However, please note that a manufacturer stating they use non iodized salt DOES NOT mean all of their products are safe.  They may contain other ingredients.

For example, Sara Lee Breads use non iodized salt.  But, many of their products use iodate based dough conditioner, so you still cannot have many of their products. 

Any other foods I should avoid? 

While you need to avoid foods high in iodine, you also need to avoid foods that could interfere with your body’s ability to take up the radioactive iodine. Soy products and cruciferous vegetables (spinach, broccoli) may decrease your body’s ability to absorb iodine. (2) (1) So avoid soy bean products (soy oil and lecithin are ok), and try to not over do the spinach and broccoli.
