The Paleo Diet is a popular diet that can work well for many chronic diseases, especially autoimmune diseases like Hashimoto’s disease. However, the Paleo Diet can be somewhat restrictive which can result in deficiencies if the dieter doesn’t carefully review their food and micronutrient intake. Iodine is one important micronutrient that may become depleted on a Paleo Diet. The Autoimmune Paleo Diet is an even more restrictive diet so the same deficiency may happen.
The connection between iodine and Hashimoto’s disease has been one of the most requested topics that I cover, so I’d like to present the research on this topic, so we can set the record straight. Please be aware that none of this is my opinion but rather a detailed analysis of what the scientific literature currently presents.
Your body has about 15 to 20 mg of iodine and 70 to 80% of it resides in the thyroid gland. Iodine is transported into the thyroid gland through the sodium-iodine symporter or NIS. The thyroid peroxidase enzyme oxidizes iodine which is then integrated into thyroglobulin resulting in the production of thyroxine (T4) and triiodothyronine (T3). Thyroid stimulating hormone (TSH) regulates this process.
Your thyroid only needs 150 to 250 micrograms a day of iodine to function properly. Once iodine intake exceeds this range, hypothyroidism and autoimmune thyroid disease may occur in some individuals.
Your gut microbiota has an intimate connection with your thyroid including connections with hypothyroidism, Hashimoto’s disease and Graves’ disease. In this research review I’d like to cover a recent paper entitled, “Microbiota and Thyroid Interaction in Health and Disease” published in the journal Trends in Endocrinology and Metabolism by Eleonare Frohlich and Richard Wahl.
The authors begin by stating that the gut microbiota can act on thyroid function due to the region of where someones lives, their diet including iodine intake, obesity, age, sex hormones, and how autoimmunity can impact the microbiota. I was impressed to see them state that the gut microbiota is linked to autoimmune disease, estrogen, iodine, and obesity. Estrogen can be a key factor in Hashimoto’s disease and a healthy gut is required for optimal estrogen metabolism and excretion through the feces.
They also mention the connection between the gut and the liver in relation to thyroid hormone metabolism in both these organ systems. Your gut is key to properly absorbing and utilizing the thyroid medication that you’re taking and they mention this as well.
In this article I cover Hashimoto’s thyroiditis natural treatment including some basic supplements that can help heal Hashimoto’s disease and hypothyroidism as well as some dietary strategies.
The thyroid gland, like any gland in your body, requires a number of basic nutrients to function properly. Every day your thyroid gland produces a certain amount of thyroid hormone that requires specific building blocks. If any of those building blocks are missing, your thyroid may not make enough thyroid hormone and you may suffer from common symptoms of Hashimoto’s thyroiditis and hypothyroidism such as:
- Weight Gain
- Hair Loss
- Cold hands and feet
- Brain fog
- Dry brittle nails and hair
- Muscle pain
Let’s talk about each nutrient that your thyroid needs and how to find out if you are deficient. It may be that you would benefit from some simple supplements for Hashimoto’s thyroiditis and hypothyroidism.
Did you know that the thyroid gland has the highest concentration of selenium compared to any organ in your body? Selenium is a powerful and essential trace mineral actually first discovered by the Swedish chemist Berzelius in 1817. Selenium mainly acts as an antioxidant, anti-inflammatory, and it is involved in the production and activation of thyroid hormone.
Selenium protects the thyroid from oxidative damage but a deficiency can lead to an increase in the weight of your thyroid which can be compounded by an iodine deficiency. When you’re deficient in selenium, you actually lose iodine more quickly so these two substances must work in perfect balance.
