Nourishing your thyroid: foods that promote thyroid health

Your thyroid, a butterfly-shaped gland in your neck, plays a crucial role in regulating your metabolism, energy levels, and overall health.

Keeping your thyroid functioning optimally is essential for well-being. In this review, we’ll explore how dietary choices can support thyroid health and help you maintain your energy and vitality.

The thyroid gland produces hormones, primarily thyroxine (T4) and triiodothyronine (T3), which control your metabolism.

An underactive thyroid (hypothyroidism) or an overactive thyroid (hyperthyroidism) can lead to various health issues. Diet can influence thyroid health by providing essential nutrients that the gland needs to function correctly.

Research Evidence

  1. Iodine for Thyroid Function

Iodine is a crucial mineral for thyroid health because it’s a key component of thyroid hormones. Your body doesn’t make iodine, so you must get it from your diet. A deficiency in iodine can lead to thyroid problems.

Sources of iodine include:

  • Iodized salt
  • Seafood (e.g., fish and seaweed)
  • Dairy products (e.g., yogurt and milk)
  • Eggs

While iodine is essential, excessive intake can also disrupt thyroid function, so it’s important to strike a balance.

  1. Selenium for Thyroid Support

Selenium is a mineral that acts as an antioxidant in the body and plays a role in thyroid hormone metabolism.

Research has shown that selenium deficiency can lead to an increased risk of thyroid disease, including autoimmune thyroid conditions like Hashimoto’s thyroiditis.

Foods rich in selenium include:

  • Brazil nuts
  • Sunflower seeds
  • Turkey
  • Chicken
  • Whole grains (e.g., brown rice and whole wheat bread)
  1. Tyrosine: Building Block of Thyroid Hormones

Tyrosine is an amino acid found in protein-rich foods. It serves as the building block for thyroid hormones. A diet deficient in tyrosine can hinder the production of these hormones, potentially leading to thyroid dysfunction.

Sources of tyrosine include:

  • Lean meats (e.g., chicken and turkey)
  • Fish
  • Dairy products (e.g., cheese and yogurt)
  • Soy products
  • Nuts and seeds
  1. Cruciferous Vegetables and Goitrogens

Cruciferous vegetables like broccoli, cauliflower, cabbage, and Brussels sprouts contain compounds called goitrogens. These substances can interfere with thyroid function when consumed in large quantities.

However, cooking these vegetables can help deactivate goitrogens, making them safe to eat in moderation. It’s essential to emphasize that for most people, the potential thyroid disruption from these vegetables is minimal and outweighed by their many health benefits.


Supporting your thyroid through dietary choices is an excellent way to maintain overall health and vitality. Ensuring an adequate intake of iodine, selenium, and tyrosine is crucial for thyroid hormone production and function.

While some foods like cruciferous vegetables contain goitrogens, cooking them can neutralize these compounds, making them safe to enjoy in moderation.

Remember that individual thyroid health can vary, and any concerns about thyroid function should be discussed with a healthcare provider.

In many cases, a balanced diet that includes these essential nutrients, along with an overall healthy lifestyle, can help keep your thyroid functioning optimally.

Incorporating iodine-rich foods like seafood and dairy, selenium sources such as Brazil nuts and whole grains, and protein-rich options like lean meats and soy products into your diet can provide the necessary support for a healthy thyroid gland.

By making these dietary choices, you can help ensure that your thyroid continues to play its vital role in regulating your metabolism and overall well-being.
