Can Diet Improve Thyroid Function? Evidence & Advice

The thyroid is a small gland in your neck, but it plays a huge role in keeping your body running smoothly. It produces hormones that control energy, metabolism, and even mood. When the thyroid does not work properly, it can cause symptoms such as tiredness, weight changes, or feeling unusually cold or hot. In the UK, around one in 20 people have some kind of thyroid disorder, highlighting how common these issues really are.

Many people wonder whether what they eat can make a difference. The short answer is yes, diet does play a role in thyroid health, although it is only one part of the bigger picture.

Understanding Thyroid Function and Diet

Thyroid function depends on a number of nutrients that your body needs to produce and regulate hormones. This is where food choices matter. For those who want to follow a thyroid diet in the UK, it is important to understand which nutrients are most valuable and where you can get them from everyday meals.

Foods to Support Thyroid Function

Some foods provide essential nutrients that support healthy thyroid activity. These include:

  • Seafood and seaweed: Rich in iodine, which is vital for thyroid hormone production.
  • Brazil nuts and sunflower seeds: Excellent sources of selenium for thyroid support.
  • Eggs and dairy products: Provide a mix of iodine, protein, and vitamins.
  • Whole grains, beans, and lentils:Offer fibre and support overall metabolism.
  • Lean meats and fish: Supply protein and zinc, which also help hormone balance.

By including these foods to support thyroid function in your daily meals, you may give your thyroid the nutrients it needs to work more efficiently. 

The Connection Between Iodine and Thyroid Health

Iodine is one of the most important minerals for thyroid health. Without enough iodine, your thyroid cannot produce the hormones your body requires. While most people in the UK get enough iodine through dairy products, seafood, and eggs, some individuals may still have lower levels. Seaweed can be an excellent source but should be consumed in moderation, as very high iodine intake can also be harmful.

Selenium for Thyroid Support

Another mineral that plays a key role is selenium. This nutrient helps convert thyroid hormones into their active form. A lack of selenium can make it harder for your body to regulate hormone activity. Foods like Brazil nuts, tuna, and mushrooms are good sources of selenium for thyroid health. Just a few Brazil nuts a week can often provide the amount you need.

Creating a Balanced Hypothyroidism Diet Plan

People with an underactive thyroid, also called hypothyroidism, often struggle with slow metabolism, fatigue, and weight gain. While diet cannot replace medicines prescribed for thyroid conditions, a basic hypothyroidism diet plan can still help improve well-being.

This type of plan usually focuses on:

  • Eating balanced meals with lean protein, whole grains, and vegetables.
  • Avoiding too many processed foods and refined sugars, which can worsen weight and energy problems.
  • Including iodine-rich and selenium-rich foods to support hormone production.
  • Limiting excessive amounts of soy and very high-fibre meals that may interfere with hormone absorption.

Practical Tips for a TSH Level Improvement Diet

Thyroid-stimulating hormone (TSH) is measured in blood tests to check how well the thyroid is working. If your TSH levels are high, it may suggest that your thyroid is underactive. A TSH-level-improvement diet may help by providing the right balance of nutrients, supporting overall thyroid health, and reducing strain on the gland. While diet alone may not bring your levels completely back to normal, it can make a positive difference alongside other treatments.

In addition to diet, lifestyle habits can also influence thyroid health. Regular exercise helps improve energy and metabolism. Managing stress through relaxation, yoga, or meditation may reduce the negative impact on hormones. Getting enough sleep is also vital for balancing the body’s systems, including the thyroid.
