Foods That Are Good For Your Thyroid Function

Boost Your Immune Response With Fruits And Vegetables

Best Foods for a Healthy Thyroid | Dr. Neal Barnard on The Exam Room LIVE

That means timing may be the most important element of eating when you have hypothyroidism. But dont discount the ripple effect that healthy foods can provide, adds Dr. Kim.

Even if fruits, vegetables, low-fat dairy, lean protein, and whole grains dont directly impact your thyroid, they can certainly be part of a stronger immune response, she says. That can be a booster not only for your thyroid, but every other system, too.

The advice I give to patients with hypothyroidism is the same that I give to family and friends, she says. Eat a healthy, well-balanced diet low in sugar and highly processed foods. Have vegetables, drink plenty of water, and if you feel like you lack certain vitamins and want supplementation, discuss it with your doctor.

Thyroid Medication And Your Food

The foods you eat can affect your thyroid medicine. They can slow down how your body absorbs medicine. It can also affect how well it does it.

  • Take medicine on an empty stomach, preferably in the morning.
  • Iron and calcium can interact with your thyroid medicine and keep it from working.
  • Ask your doctor or pharmacist for more information about timing your food and other meds around your thyroid treatment.

Eating An Elimination Diet With Hypothyroidism

Dietary triggers can increase distress in the gastrointestinal tract, chronic inflammation, and possibly elevated thyroid antibodies. Eating reactive foods can cause digestive symptoms like diarrhea, bloating, acid reflux, gas, or cramping. Other symptoms may be respiratory, muscular, or related to the skin.

An elimination-style diet can help identify your specific dietary triggers and reduce uncomfortable symptoms.

It can be challenging to connect specific foods to specific symptoms when eating the same way all the time. Still, the more you unknowingly eat problematic foods, the body’s ability to protect itself weakens, and the reactions become less specific and more chronic.

An elimination diet helps identify foods your body doesn’t tolerate well to remove them from your diet. An elimination diet typically involves two stages: removing potential food triggers and then intentionally reintroducing them into your diet to determine whether or not you tolerate them.

There are many different types of elimination diets, including:

  • Autoimmune protocol diet
  • Rare foods elimination diet
  • Fasting elimination diet

Other elimination diets include lactose-free, sugar-free, gluten-free, and wheat-free diets. Learn more in the articles below about specifically implementing an elimination diet with hypothyroidism or Hashimoto’s.

Coffee: Time Your First Cup Carefully In The Morning

Per a study in the journalThyroid, caffeine has been found to block absorption of thyroid hormone replacement. “People who were taking their thyroid medication with their morning coffee had uncontrollable thyroid levels, and we couldn’t figure it out,” says Dr. Lee. “I now have to be very careful to tell people, ‘Only take your medication with water.'” You should wait at least 30 minutes after taking your medication before having a cup of joe.

Foods With Soy Including Edamame Tofu And Miso

Theres long been concern over the potential negative effects that certain compounds in soy called isoflavones may have on the thyroid. Some researchers believe that too much soy may increase a person’s risk for hypothyroidism. A study published in March 2019 in Scientific Reports, however, found that soy has no effect on thyroid hormones and very modestly raises thyroid stimulating hormone levels.

So there are no specific dietary guidelines, but some research does suggest that consumption of soy may interfere with your ability to absorb thyroid medication. For that reason, you may want to wait four hours after eating soy-based foods before taking your regular dose. Check with your doctor to see whats best for you.

Foods That Support Thyroid Health

Your diet has an enormous effect on your thyroid health and function. There are some foods that support thyroid health, while other foods may actually diminish thyroid function. Certainly, its best to consume enough of the foods that support thyroid health. Just as you shouldnt ignore the effect your diet has on your overall health, you shouldnt ignore how nutrition can help, or harm, your thyroid. If youre unsure of the condition of your thyroid, a knowledgeable healthcare practitioner can request blood tests to determine if your thyroid is healthy. Its a good idea for those who have known thyroid issues to get tested every five years, beginning at age thirty-five.

Healthy thyroid function production happens when your thyroid is provided healthy nutrition. Iodine, iron, selenium, and zinc are all extremely important for thyroid health. Iodine deficiency is a frequent, contributing factor for hypothyroidism, and, as a world-wide concern, affects as many as two billion people. Iodine is a necessary component for thyroid hormone synthesis and becomes a part of the thyroid hormone itself. In fact, its impossible for the thyroid to produce hormones without sufficient iodine. A very healthy diet, especially one that includes foods that are a good source of iodine, should provide the minimum amount of iodine your body needs, which is 150 micrograms daily. If your diet doesnt provide the amount of iodine your body needs, an iodine supplement can help your requirements.

Hypothyroidism can cause the body’s metabolism to slow down, Frechman says. That means it’s easy to put on pounds if you aren’t careful. “You want to avoid foods with excess amounts of sugar because it’s a lot of calories with no nutrients,” she says. It’s best to reduce the amount of sugar you eat or try to eliminate it completely from your diet.

Cruciferous And Leafy Green Vegetables

Yes, you should eat your fresh veggies if you have hypothyroidism! But try to avoid chowing down excessively on cabbage, broccoli, kale, Brussels sprouts, cauliflower, and spinach, per Morey. These veggies tend to be higher in goitrogens than their veggie counterparts.

Dont cut them out completely, though: Northwestern Medicine says its a myth that people with hypothyroidism should avoid cruciferous vegetables, spinach, and kale, since you would have to eat unusually high amounts of these foods to have any negative side effects on your thyroid.

Morey says the good news is that high amounts of goitrogens only seem to be an issue for people who have an iodine deficiency . She adds that their effect on thyroid function can typically be further reduced by cooking these foods thoroughly before eating them, as opposed to eating them raw or undercooked.

How Does Diet Affect Your Thyroid

Speed Up Metabolism with Foods That Boost Thyroid Function | Hypothyroidism

Diet plays a significant role in overall health whether you have a thyroid condition or not. Research is ongoing to understand the exact impact of food and nutrients on thyroid health, but there is some evidence for how specific nutrients affect thyroid function.

For most people with a thyroid condition, medications like levothyroxine are essential. Nevertheless, an appropriate dietary regimen can complement treatment and favour remission by improving thyroid function, as well as regulating levels of T3, T4, and thyroid antibodies. So, lets look at the science.

Cruciferous Vegetables Like Broccoli And Cauliflower

Cruciferous vegetables, such as broccoli and cabbage, are full of fiber and other nutrients, but they may interfere with the production of thyroid hormone if you have an iodine deficiency. So if you do, its a good idea to limit your intake of Brussels sprouts, cabbage, cauliflower, kale, turnips, and bok choy, because research suggests digesting these vegetables may block the thyroid’s ability to utilize iodine, which is essential for normal thyroid function. However, according to the Mayo Clinic, you would need to consume a significant amount of cruciferous vegetables for it to truly impact iodine uptake.

If you have been diagnosed with both hypothyroidism and iodine deficiency, there are some things you can do to make these vegetables less harmful. Cooking them can reduce the effect that cruciferous vegetables have on the thyroid gland, and limiting your intake of these vegetables to 5 ounces a day may help as well, since that amount appears to have no adverse effect on thyroid function.

Processed Foods In Packages And The Frozen Aisle

“Processed foods tend to have a lot of sodium, and people with hypothyroidism should avoid sodium,” Frechman says. Having an underactive thyroid increases a person’s risk for high blood pressure, and too much sodium further increases this risk.

Read the “Nutrition Facts” label on the packaging of processed foods to find options lowest in sodium. People with an increased risk for high blood pressure should restrict their sodium intake to 1,500 milligrams a day, according to the American Heart Association.

Whole Grains Help Ease Constipation A Symptom Of Hypothyroidism

7 Foods That Can Affect Your Thyroid Function

Constipation is a common symptom of hypothyroidism. Whole-grain foods such as cereal, bread, pasta, and rice are high in nutrients in addition to fiber, which can help with bowel regularity. However, fiber can interfere with synthetic thyroid hormones, cautions Turner. Some people with hypothyroidism choose to avoid whole-grains altogether, but if you do choose to eat them, “the recommendation is to take your thyroid medication several hours before or after eating foods rich in dietary fiber,” she says.

Thyroid Hormone And Brain Development

Thyroid hormone is important for different body functions however, it has a crucial role in the development of foetal brain . The process of foetal hormonal maturation is controlled by the thyroid receptors. Those receptors, including TR and TR subtypes, are expressed on cell nucleus and regulate production of thyroid hormones through gene expression. The foetus depends upon maternal thyroid hormone up until 12 weeks of gestation, when the thyroid receptors start to appear in the cerebral cortex and the cerebellum. By then, the foetal thyroid is able to concentrate iodine in order to synthesise thyroxine .

Not So Good: Fast Food

Similar to processed foods, fast food chains also aren’t required to use iodized salt in their foods.

According to the American Thyroid Association , you should avoid restaurant foods since there is no reasonable way to determine which restaurants use iodized salt.

Analysis of the iodine content of commons foods by the United States Department of Agriculture found that one fast food hamburger patty contained 3.3 mcg of iodine per 100 g whereas a non fast-food ground beef patty contained 8 mcg of iodine per 100 g.

Is Juicing Good For Hypothyroidism

Juicing extracts the juice from fresh fruits or vegetables, containing most of the vitamins, minerals, and phytonutrients found in the fruit. However, when you juice fruits and vegetables, you leave behind the pulp and miss out on whole fruits and vegetables fiber.

Dietary fiber is important because it helps stabilize blood sugar, maintain regular bowel movements, and support a healthy gut microbiome. A healthy gut microbiome is particularly important for autoimmune conditions like Hashimoto’s thyroiditis.

Some argue that juicing gives your digestive system a rest from digesting the fiber, and your body can absorb the nutrients better. There are also claims that juicing can reduce cancer risk, boost immunity, remove toxins, aid digestion, and support weight loss. However, there is limited scientific research to back this up.

If you don’t enjoy eating fruits and vegetables or don’t currently get enough of them in your diet, juicing may be a way to get in more servings. You can use the leftover pulp in cooking or baking. Still, we recommend blending instead of juicing to make a drink that contains all the healthy phytonutrients and fiber, which will help you feel more satiated.

Dietary Effect On Thyroid Dysfunction And Suggested Pathogenesis

The Best Foods For Thyroid Health


Iodised salt, seafood , and some grains and breads are common dietary sources of iodine . In routine clinical practice, patients will often inquire about dietary changes they can make to treat or reverse their thyroid dysfunction. In general, there is reasonable evidence that adequate but not excessive iodine intake is beneficial for thyroid health as well as selenium supplementation for patients with Graves disease . Aside from these, the scientific data showing that dietary changes can significantly benefit hypo- or hyperthyroidism is sparse .

Cruciferous vegetables

Cruciferous vegetables are vegetables of Brassicaceae family, including kale, turnips, cauliflower and others, which are rich in indole glucosinolate. In animal studies, this compound was found to degrade into a goitrin metabolite called thiocyanate that inhibits iodine uptake by the thyroid cell. It works by competitive inhibition of the sodium/iodide symporter, and hence inhibiting the synthesis of thyroid hormones . However, data are lacking in examining the serum concentrations of goitrin following the ingestion of cruciferous vegetables.

Can Nutrition Actually Help Boost Our Thyroid Health

Foods alone can’t cure thyroid issues, says Julie Harris RDN, LDN and CPT. However, a combination of nutrients and medications can help restore thyroid function and reduce symptoms.

For one, may have some impact on thyroid health. According to Lisa Richards, nutritionist, and author of The Candida Diet, eating foods that mitigate inflammation can help people with autoimmune diseases such as Graves’ or feel better. Anti-inflammatory foods include things like:

An unhealthy or imbalanced gut leads to many negative health outcomes, including poor immune function. Disorders of the immune system autoimmune diseases are primarily inflammatory in nature, Richards says.

Richards continues, The gut plays a role in supporting a healthy thyroid and controlling inflammation. Consuming superfoods rich in gut health-promoting nutrients like antioxidants and fiber can help to mitigate thyroid conditions and symptoms.

In short, if you have autoimmune thyroid issues, you can ease some of the inflammatory damage your body is experiencing by eating superfoods and anti-inflammatory foods but its always best to work with your healthcare practitioner and a nutritionist to understand which foods are best for you, and how they play into your disease management routine.

Diet And Thyroid Medication

Youll want to make sure youre taking your thyroid medication on an empty stomach to promote optimal absorption. Experts suggest taking thyroid medications like levothyroxine at least 30 to 60 minutes before breakfast or at least 3 to 4 hours after dinner .

Keep in mind that this includes avoiding beverages, foods, and supplements that could interfere with medication absorption.

Certain supplements and even coffee can significantly impact thyroid medication absorption, so its important to always take your medication on an empty stomach and wait at least 30 minutes before consuming foods or beverages besides water. You should also avoiding taking thyroid medication within 4 hours of taking iron or calcium supplements (

If you have hypothyroidism, try incorporating the following nutritious foods into your diet:

Keep in mind that some people with hypothyroidism may benefit from avoiding gluten and other ingredients like dairy, but others may not have to cut these foods from their diet and may be able to consume gluten and dairy without issue.

This is why its important to develop an eating plan that works for you and your specific health needs.

If you can, work with a registered dietitian who can help identify which foods may need to be eliminated and help develop a balanced eating plan that does not unnecessarily cut out nutrient-rich ingredients.

Ask Your Provider About Supplements

For the most part, both Wattenbarger and Morey say that an extensive list of supplements just isnt necessary for treating hypothyroidism. I generally recommend avoiding supplementation in specific nutrients like iodine, zinc, and selenium unless directed by a healthcare professional, says Morey. Supplements contain large amounts of these minerals, and consuming too much of them can lead to gastrointestinal problems in mild cases and more serious problems, such as deficiency in other nutrients and heart and kidney failure, in extreme cases.

But you might want to consider asking your doctor about a multivitamin, says Wattenbarger, especially if you know you dont have the best diet or if youre on a vegan diet that is likely to be coming up short on key nutrients. Remember, you should wait at least four hours between taking your thyroid hormone replacement medication and a multivitamin or any supplements that contain iron, aluminum, and calcium.
