Best foods for thyroid health

Best foods for thyroid health

It's estimated one in twenty people suffer from a thyroid condition, but the actual figure is believed to be much higher as many people are unaware they have a thyroid condition.  Women are much more likely to suffer than men, with as many as one in eight for women developing a thyroid condition in their lifetime. Here we explain thyroid conditions, who is at risk of thyroid problems and the best foods for thyroid health.

What are thyroid conditions?

The thyroid is the gland in the front of your neck that moves when you swallow. The thyroid is responsible for releasing thyroid hormones which control your metabolism, and it is your metabolism that determines how much energy you have and how you store fat, so the thyroid plays a big role in our health. It is also involved in cognitive function, cell growth and healing.

There are a few health conditions that can affect the thyroid. The main condition to affect it is autoimmunity to the thyroid gland, called 'Hashimoto’s disease', where the immune system attacks and damages the thyroid gland and in most cases causes an underactive thyroid. There is another type of autoimmune disease against the thyroid, called 'Graves disease' which causes the thyroid to become overactive.

Always consult with your Doctor before taking supplements if you have an existing thyroid condition or you're taking prescribed medication.  

The thyroid may also become underactive due to a lack of Iodine in your diet. Thyroid hormones are created from Iodine, so a lack of it causes the thyroid to slow down.

Iodine deficiency can also cause the thyroid gland to enlarge and develop into a goitre. Thankfully this is quite rare now, however it does still occur in some developing countries and some studies show Iodine deficiency is more common among those on a vegan diet.  An increasing number of plant-based milk alternatives are now fortified with Iodine so it's useful to opt for these. 

Other types of thyroid diseases include thyroid-nodular disease, where nodules grow on the thyroid, and thyroid cancer which is fortunately quite rare.   

Underactive vs Overactive Thyroid

The thyroid can be underactive or overactive for a few reasons.

Underactive thyroid

An underactive thyroid is known as hypothyroidism and is the most common thyroid issue. 

Hypothyroidism comes with a range of symptoms, including tiredness, sensitivity to the cold, weight gain, constipation, depression, slow movements and thoughts, muscle weakness and cramps, dry and itchy skin, weak nails, loss of libido, pain and numbness in the hands and fingers, and irregular and heavy periods

Overactive thyroid

If the thyroid is overactive (also known as hpyerthyroidism) then you can experience a range of symptoms including weight loss, nervousness, anxiety, irritability, mood swings, difficulty sleeping, sensitivity to heat, swelling of the thyroid gland, twitching and trembling.

Who is at risk of suffering from thyroid conditions?

Anyone can suffer from thyroid conditions, however they affect women more than men. There is also a strong genetic link with thyroid conditions, so if you have a close family member who has a thyroid disease, you are more likely to have experience thyroid issues.

One of the biggest causes of thyroid conditions in Third World countries is the lack on nutrients in diets, especially Iodine.

Best foods for thyroid conditions

Here we explain the best nutrients and foods for an underactive thyroid and supporting healthy thyroid issues. 

Iodine

Iodine is an essential nutrient as it is used directly for the production of thyroid hormones. The thyroid makes the hormone T4. T4 then travels to the liver and some of the T4 is converted into T3, another type of hormone. T3 is more potent than T4. For this conversion to happen, the liver requires other nutrients we list below.  Severe iodine deficiency can cause hypothyroidism.  

Good foods for Iodine: The best sources are seaweed, eggs, fish and seafood, dairy products. Plant sources include kale, courgettes, beans and watercress, although in much lower amounts.

Always consult with your Doctor before taking supplements if you have an existing thyroid condition or your taking prescribed medication. 

Selenium

Selenium is needed for the enzyme that converts T4 into T3 in the liver. European soils do not contain much Selenium, so sub-optimal levels in the diet are fairly common.  

Good sources of Selenium: Brazil nuts, beans, broccoli, spinach, potatoes, white meat, fish, shellfish and eggs.

Try our Creamy Spinach Soup recipe.

Zinc & Copper

Zinc and Copper work together in balance in the body and are needed for the conversion of T4 into T3. In deficiency states of Zinc and Copper, the conversion becomes less effective.

Good foods for Zinc: oysters contain more Zinc per serving than any other food, and red meat and poultry are other good sources.  Lentils, beans and chickpeas, nuts, seeds and oats are all high in Zinc.

Good foods for Copper: wholegrain foods such as wholewheat spaghetti, quinoa and brown basmati rice, nuts such as peanuts, cashews and walnuts, sees including sesame and sunflower seeds, and pulses.

Magnesium

Magnesium is a mineral superhero, involved in over 300 processes in your body, and one of these is helping enzymes in the body that convert T4 into T3.

Great foods for Magnesium: kale, spinach, dry beans, whole grains, nuts and seeds, black-eyed peas, tempeh, beans and tofu.

B Vitamins

B Vitamins are essential in the production of all thyroid hormones.

Good foods for B Vitamins: Wholegrains, bread, fortified cereals, soya beans, nuts, pork, chicken, turkey, lamb and beed. 

Vitamin D3

Vitamin D is essential for a normal immune response. In the majority of thyroid conditions, the thyroid glad does not produce enough T4 as it has been damaged by the body’s immune system, so maintaining your immune health supports your thyroid health. 

Good foods for Vitamin D3: The best source of Vitamin D is sunlight and unfortunately Vitamin D is only found in a small number of foods, mainly of animal origin, such as oily fish, meat and egg yolks.  Breakfast cereals and plant-based milk alternatives are often fortified with Vitamin D.  The most effective source of Vitamin D is Vitamin D3 from vegan-friendly plant sources such as lichen.

Probiotics

Around 20% of the conversion of T4 to T3 occurs in the gut, and probiotics are directly involved in this conversion.

Probiotics are healthy bacteria and good sources include: yoghurts, sauerkraut, tempeh, kombucha, and fruits including bananas and grapefruits.

Remember, if you have an existing health or thyroid condition, or you're taking prescribed medication for a thyroid condition, always consult with your Doctor before taking supplements.
