Hashimoto’s and Goitrogens: Exploring the Link

In the video “Hashimoto’s and Goitrogens: Exploring the Link” by Martin Rutherford, he delves into the common misconception surrounding the relationship between Hashimoto’s Thyroiditis and goitrogens. He explains that goitrogens, which are found in various vegetables such as kohlrabi, spinach, and broccoli, were initially believed to block iodine from entering the thyroid and inhibit the production of thyroid hormone. However, Rutherford suggests that this belief has changed with new developments in understanding Hashimoto’s, stating that goitrogens can actually be beneficial for individuals with this condition. He challenges the notion that iodine is good for hypothyroidism and emphasizes the importance of distinguishing between hypothyroidism and Hashimoto’s. Ultimately, Rutherford aims to provide valuable information and debunk common misconceptions surrounding the topic of Hashimoto’s and goitrogens.

Common Misconceptions about Hashimoto’s and Goitrogens

There are many misconceptions about Hashimoto’s thyroiditis and its relationship with goitrogens. Goitrogens are substances that can hinder the absorption of iodine by the thyroid gland, which plays a crucial role in the production of thyroid hormones. However, it is important to understand that not all individuals with Hashimoto’s thyroiditis will be affected by goitrogens in the same way. In fact, the role of goitrogens in the development and management of Hashimoto’s thyroiditis is often misunderstood. In this article, we will delve deeper into the history of goitrogens, their connection to Hashimoto’s thyroiditis, and clarify some of the misconceptions surrounding this topic.

The History of Goitrogens and their Connection to Hashimoto’s

The link between goitrogens and the thyroid has been recognized for many years. In 1928, researchers discovered that certain vegetables, known as goitrogens, have the ability to inhibit the absorption of iodine by the thyroid gland. This discovery was significant because iodine is essential for the production of thyroid hormones. Without sufficient iodine, the thyroid gland cannot produce enough hormones, which can lead to hypothyroidism.

It was initially believed that goitrogens were harmful to individuals with hypothyroidism, including those with Hashimoto’s thyroiditis. However, recent research has shown that the relationship between goitrogens and Hashimoto’s thyroiditis is more complex than previously thought. In fact, goitrogens may not necessarily be detrimental to individuals with Hashimoto’s thyroiditis, and their role in the development and progression of the condition is still not fully understood.

Understanding the Thyroid Hormone Production Process

To understand the role of goitrogens in Hashimoto’s thyroiditis, it is important to have a basic understanding of the thyroid hormone production process. The thyroid gland, located in the neck, produces two main hormones: thyroxine (T4) and triiodothyronine (T3).

The production of thyroid hormones begins in the hypothalamus, a small region in the brain. The hypothalamus releases thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to release thyroid-stimulating hormone (TSH). TSH then signals the thyroid gland to produce and release T4 and T3.

The thyroid gland uses iodine, obtained from the diet, to produce T4 and T3. The process involves an enzyme called thyroid peroxidase (TPO), which helps the thyroid gland incorporate iodine into the structure of T4 and T3.

The Role of Goitrogens in Inhibiting Iodine Absorption

Goitrogens are substances found in certain vegetables, such as broccoli, cabbage, and spinach, that can interfere with the absorption of iodine by the thyroid gland. These substances can inhibit the function of the TPO enzyme, preventing iodine from being incorporated into the structure of T4 and T3.

In individuals with sufficient iodine levels, the inhibitory effect of goitrogens may have minimal impact on thyroid hormone production. However, in individuals with low iodine levels, the inhibitory effect of goitrogens can further decrease the production of thyroid hormones, potentially leading to hypothyroidism.

It is worth noting that cooking or processing goitrogenic vegetables can reduce their goitrogenic effect. So, simply avoiding these vegetables may not always be necessary for individuals with Hashimoto’s thyroiditis.

The Link between Goitrogens and Thyroid Stimulating Hormone (TSH)

High levels of TSH in the blood indicate that the thyroid gland is not producing enough thyroid hormones. Traditionally, elevated TSH levels were associated with hypothyroidism, including Hashimoto’s thyroiditis. It was believed that goitrogens could increase TSH levels by inhibiting the production of thyroid hormones, leading to an underactive thyroid.

However, recent research suggests that the relationship between goitrogens and TSH levels is more nuanced. In some individuals with Hashimoto’s thyroiditis, goitrogens may have little to no effect on TSH levels. Other factors, such as the presence of thyroid antibodies, may play a more significant role in TSH elevation in these individuals.

The Role of Thyroid Peroxidase Enzyme in Hashimoto’s

Thyroid peroxidase (TPO) is the enzyme responsible for incorporating iodine into the structure of thyroid hormones. In individuals with Hashimoto’s thyroiditis, the immune system mistakenly produces antibodies that target and attack the TPO enzyme. This immune response can lead to inflammation and destruction of thyroid tissue, eventually causing hypothyroidism.

The presence of TPO antibodies in the blood is a key marker for the diagnosis of Hashimoto’s thyroiditis. It indicates that the immune system is actively targeting the TPO enzyme. Testing for TPO antibodies is essential for individuals suspected of having Hashimoto’s thyroiditis, as it helps confirm the diagnosis and guide treatment decisions.

The Importance of Testing for TPO Antibodies

If you suspect that you may have Hashimoto’s thyroiditis, it is crucial to be tested for TPO antibodies. This test can be performed by a healthcare provider and involves a simple blood draw. Detection of TPO antibodies confirms the presence of autoimmune thyroid disease and helps distinguish Hashimoto’s thyroiditis from other forms of hypothyroidism.

Knowing whether you have Hashimoto’s thyroiditis can guide your treatment plan. It can help your healthcare provider determine the appropriate medication dosage, monitor disease progression, and identify potential complications associated with the condition.

Lifestyle Changes and Autoimmunity in Hashimoto’s

Hashimoto’s thyroiditis is an autoimmune condition, which means that the immune system mistakenly attacks healthy thyroid tissue. While the exact cause of autoimmune diseases is still unclear, various factors, including genetic predisposition and environmental triggers, are thought to contribute to their development.

Certain lifestyle changes may help manage the symptoms and slow the progression of Hashimoto’s thyroiditis. These changes may include adopting a nutrient-rich diet, reducing stress levels, getting regular exercise, and ensuring adequate sleep. Additionally, some individuals may benefit from avoiding specific food triggers, such as gluten or dairy, although the evidence supporting these dietary modifications is limited.

However, it is essential to note that lifestyle changes alone may not be sufficient to manage Hashimoto’s thyroiditis. It is important to work closely with a healthcare provider who specializes in thyroid disorders to develop a comprehensive treatment plan that addresses individual needs.

The Shift in Understanding Hashimoto’s and Autoimmune Conditions

The understanding of Hashimoto’s thyroiditis and autoimmune conditions, in general, has evolved significantly over the years. Previously, goitrogens were considered harmful to individuals with hypothyroidism, including those with Hashimoto’s thyroiditis. However, with the advancement of research, it is now known that goitrogens may not necessarily be detrimental to individuals with Hashimoto’s thyroiditis and may even have some benefits.

Furthermore, it has become clear that Hashimoto’s thyroiditis is more prevalent than previously believed, with estimates suggesting that a significant portion of the population may have the condition or silent Hashimoto’s without exhibiting noticeable symptoms. This shift in understanding has highlighted the need for improved diagnostics and treatment approaches for Hashimoto’s thyroiditis.


Hashimoto’s thyroiditis is a complex condition that requires careful management and individualized treatment. While goitrogens were once considered harmful to individuals with Hashimoto’s thyroiditis, recent research suggests that their impact may be more nuanced. It is important to seek guidance from a healthcare provider who specializes in thyroid disorders to understand the specific dietary and lifestyle changes that may benefit you based on your unique situation. Remember, always consult with a healthcare professional for personalized advice and guidance regarding your health.
