Benefits Of A Low-Iodine Diet For Your Health

It’s a question that is essential to your health: are you getting too much or too little iodine?

We often refer to iodine as the “goldilocks” nutrient of your thyroid. Not too much, not too little, things need to be just right to secure your long-term health. Let’s dive into what that means, and how you can achieve it with easy, actionable changes…

The Basics on Iodine

Iodine is one of the nutrients that your thyroid needs to thrive (Read: 7 Rare nutrients your thyroid needs to survive).

Furthermore, healthy daily iodine intake is set at 150 micrograms per day¹. If you are on thyroid medication, you can even obtain your iodine through your thyroid medication.

The fact is that you do not need to bring large amounts into your diet. In fact, you would do well to limit extra iodine.

The Effects of Low-Iodine Diets

The low iodine diet is typically used when preparing for radioactive iodine testing or treatment (Read: 10 Super important questions to ask before starting a radioactive iodine regimen).

The idea behind this diet is to keep your iodine levels really low. Therefore, your thyroid gland will more readily take up the radioactive iodine once you receive it.

A review of current studies demonstrates that a strict or moderate low iodine diet results in higher ablation rates (higher success rates of treatment) than a normal diet³. That said, more studies are needed to determine the long-term effects of the low iodine diet.

The usefulness of a low-iodine diet is demonstrated in an interesting case study of a young woman with papillary thyroid cancer. After being diagnosed, she had a total thyroidectomy.

This was to be followed by an ablation. The pre-ablation scan did not show elevated thyroid activity. This did not make sense based on the results of previous imaging and biopsy.

This led the patient to admit she had not been compliant with the recommended low-iodine diet.

This is important because the pre-ablation scan is used to:

• Determine the treatment dose of radioactive iodine
• Check for malignancies
• Suggest prognosis

Overall, you most definitely want to avoid getting a false imaging result.

Can A Low-Iodine Diet Help with Hashimoto’s?

When a group of unmedicated patients with Hashimoto’s thyroiditis were placed on an iodine-restricted diet, they had a much higher recovery rate to a euthyroid state.

This is compared to a group of patients with Hashimoto’s thyroiditis who were not placed on an iodine-restricted diet⁴.

These results were seen after three months. The patients who had not reached a euthyroid state by three months of a low-iodine diet still saw improvements in their TSH levels⁴.

Similarly, a larger study of iodine restriction in patients diagnosed with subclinical hypothyroidism also found that a low-iodine diet for three to six months significantly reduced TSH levels⁵.

How To Enjoy A Low-Iodine Diet

Doing a low-iodine diet may seem daunting at first. But, if you stick to whole, unprocessed foods you’ll realize it’s quite simple.

On a low-iodine diet, you can eat a variety of fresh meats along with vegetables, fruits, grains, unsalted, unprocessed nuts and a variety of herbs and spices.

Foods To Include

• Fresh meat
• Vegetables
• Fruit
• Unsalted, unprocessed nuts
• Coconut
• Grains
• Egg whites
• Alternative milks (almond, hemp, rice, coconut)
• Non-iodized salt
• Fresh or dried herbs and spices
• Honey ^2,6

Foods To Avoid

• Processed foods
• Cured meats
• Dairy products
• Egg yolks (egg whites are okay)
• Fish and shellfish
• Seaweed and thickeners
• Soy products
• Chocolate
• Breads and baked goods containing calcium iodate or potassium iodate
• Red dye #3
• Blackstrap molasses
• Herbal supplements^2,6

Additional Considerations

You will need to check your supplements for iodine content and potentially eliminate calcium, multivitamin, selenium and fish oil supplements.

A few other places iodine can be hiding are lotions made with seaweed products, water purification tablets, and toothpaste (if containing alginates).

How Long?

Follow this diet for the two weeks preceding radioactive iodine testing or treatment.

This appears to be sufficient for creating an iodine-deficient state for treatment as long as you are careful to follow the diet guidelines³.

A Word Of Caution

Due to the changes, you will be making in order to follow a low iodine diet, you may run into a couple deficiencies.

The first is low EPA, an omega 3 fatty acid. EPA is in fish and fish products, which you would avoid during the low-iodine diet.

Another is sodium. Severe sodium deficiency has been reported a handful of times in the scientific literature^7-9. This is more of a concern in elderly patients or patients on certain diuretic drugs.

However, a recent study found that overall, low iodine diets are not a risk factor for sodium deficiency and that this is not a common outcome for people on a low iodine diet¹⁰.

Also, recall that you can have salt on the low-iodine diet as long as it is non-iodized salt.
