What is the best diet for hypothyroidism?

I get a lot of queries about the best diet for hypothyroidism because it’s such a common medical diagnosis these days. So let’s talk! This awesome article will cover important nutrients to consider along with the thoughts on the best foods for hypothyroidism and foods to avoid (including the study on gluten and soy). There is certainly SO much misinformation out there so it is time to set the record straight.

What is hypothyroidism?

Do you have hypothyroidism? If you do, you are not alone: subclinical hypothyroidism is approximated to occur in between 3-15% of the population and is more common in ladies, those who are older or those with lower iodine status. A major cause of hypothyroidism is Hashimoto’s, or autoimmune, hypothyroidism.

Hypothyroidism occurs whenever your thyroid gland doesn’t produce sufficient thyroid hormone. It can be overt, exactly where T4 hormone is low, or even what is called ‘subclinical’ meaning that T4 is within the normal range but thyrotropin, or TSH, is low. If you need to learn more about hypothyroidism, it is a great overview .

Signs of hypothyroidism

It is important to be mindful of hypothyroidism sensation and pay attention to what your body will be telling you. If you are experiencing any of these persistent signs + symptoms of hypothyroidism, you need to talk to your doctor:

  • Cold intolerance
  • Exhaustion
  • Cognitive + feeling changes (forgetfulness, depression and irritability)
  • Hair loss
  • Low libido
  • Unusual weight gain
  • Constipation

Best diet regarding hypothyroidism

Despite what the actual internet will tell you, there is zero technological literature studying any one dietary design for hypothyroidism. Yep, that’s correct, ZERO. Meaning everything you’re reading about going keto, or even vegan, or gluten free is usually just someone’s opinion.

Of course , just because the evidence hasn’t given us the ‘perfect’ diet plan for hypothyroidism that doesn’t mean that a person shouldn’t try to nourish themselves. We all have a bit of insight into specific nutrition and foods that might be an issue intended for someone with low thyroid functionality.

What’s more, hypothyroidism can increase your risk of heart problems and may increase constipation so we certainly want to address this with the meal choices we make. My tips? Eat a lot more plants, of course! A potent diet is a nutrient-dense healthy dietary pattern filled with entire plant foods and based on among the best-researched dietary designs in existence: the Mediterranean diet.

Eating more high dietary fibre plant foods such as whole grains, fresh fruits, vegetables will support healthy motion of the gut, helping you to minimize constipation. The plantS flood your body with nutritional vitamins, minerals and anti-inflammatory phytochemicals to assist support of overall health and healing. Consuming more plants will also help reduce your intake of saturated fats that can raise cholesterol levels while providing heart-healthy monounsaturated fats from avocados, additional virgin olive oil and nuts plus seeds.

Now that the particular boring (yet EFFECTIVE), you should be healthy! ’ advice is out of the way, let’s look at what the research has to say on specific nutrients.

Let’s just say that in case you are on a vegan or plant-based diet plan, it’s time to take note: 

Specific nutrition to watch when you have hypothyroidism


Iodine is crucial for the production of thyroid body hormone. Iodine is typically found in seafood, ocean vegetables as well as dairy. Iodine particles of plant foods is usually low to nonexistent and at the particular mercy of soil iodine ranges which of course will diminish once the soil is further from the ocean. Iodine deficiency is a leading reason for thyroid issues which is why in 1949 Canada created a public wellness mandate to iodize salt. Let’s say that again: far from being a health hazard like the wellness conspiracy theory crowd tries to sell you, iodized salt was created as a food-first technique to protect our thyroid.

We need 150mcg of iodine per day and if you have anything going on with your thyroid, it is NOT recommended that you have a supplement because excess iodine is definitely harmful too. The iodine particles of seaweed can vary widely (from low to extremely high! ) so is also not considered a suitable choice. Instead, eat fewer hyper-processed meals, which tend to be filled with too much sodium, and then enjoy healthy homecooked foods seasoned with iodized salt to obtain what you need. If you prefer sea sodium, you can actually get iodized versions associated with sea salt too – that is what I recommend.


Selenium is an important trace mineral that helps to fight oxidative damage in the body as part of the antioxidant chemical superoxide dismutase (SOD). For this reason, it really is thought that selenium may help protect a thyroid problem from further autoimmune damage but clinical trials have had varied results. For this reason – and the proven fact that excess selenium is dangerous – supplementation isn’t recommended. But obtaining enough selenium from food is certainly beneficial! For those of us on a plant-based diet plan, I’ll keep it simple: eat a Brazilian nut a day. Really, that’s all you have to! There aren’t a lot of plant meals rich in selenium so lucky for all of us, Brazil nuts have a ton.

Vitamin D

Whilst we typically think of it as a bone-health vitamin, vitamin D has both potent and immune-modulating functions. Lower degrees of vitamin D are commonly associated with autoimmunity, yet evidence has been less clear within hypothyroidism . In one community-based trial, achieving sufficient calciferol status was associated with a 30% reduced risk of hypothyroid. And in an additional 2015 meta-analysis, those with autoimmune hypothyroid had lower vitamin D standing than those without. Because of the importance of calciferol to overall health, and how common deficiency is, I highly recommend getting your calciferol levels tested if you are able so that your doctor can recommend the right dose to create your correct levels. If not, I suggest 1000IU of vitamin D3 within the brightest 6 months of the year plus 2000IU of vitamin D3 like a safe and conservative dose in the future.

Vitamin B12

Decreased B12 status has been connected with increased hypothyroid illness in clinical trials. Those people on a plant-based or vegan diet, as well as those over the age of fifty, need to know that a daily B12 dietary supplement is critical for maintaining stores of the nutrient vital for metabolism. This might also be important if you have celiac condition or inflamed bowel disease, which may hinder your absorption of the nutrient. We want 2.4mcg a day but most products offer more than that. If you can look for a 50mcg or 500mcg supplement, fantastic – but most common is 1000mcg and it isn’t harmful.

Foods for hypothyroidism

Hemp Hearts

Hemp contains omega 3 fatty acids to assist and fight inflammation as well as ample amounts associated with zinc, which is important not only for thyroid metabolism but also minimizing irritation and supporting appropriate immune reaction.

Brazil Nuts

1-2 Brazil nuts per day will give you all the selenium you need. Simply no supplement necessary! It’s worth observing that Brazil nuts are so full of selenium that you don’t want to overdo it. Stick to your 1-2 serving.


Fruits are incredibly nutrient-dense, in particular dietary fibre to support healthy digestion as well as potent phytochemicals that help squelch oxidative damage. Oxidative stress is considered to increase inflammation that makes cellular harm in the thyroid worse . A single older study suggests that hypothyroidism might be associated with higher levels of oxidative tension .

Steel reduce or thick old-fashioned oats

Oats contain soluble fiber that help to bind cholesterol plus remove it from the body, helping to decrease blood cholesterol levels. A glass of cooked oats has approx 5 grams of total dietary fibre, as well as 1.5-ish milligrams associated with zinc for the immune system. Metabolism and digestive function can slow the hypothyroid, producing slow-burn. Also high fibre carbs are extremely important to keep your blood sugar from rising plus energy levels stable.


Lentils contain significant amounts of protein, fibre and iron – which is crucial for the production of thyroid hormones . Hashimoto’s and anemia are common co-occurrences and it’s important to ensure appropriate iron status.


Yes, all veggies (more on that in the ‘avoid’ section). To take care of your heart, your own gut and fight inflammation, you desire all the nutrient density you can get. Consider making half your plate veggies at almost every meal.

Foods to avoid for hypothyroidism

Honestly, most of this particular avoid section is mythbusting plus medication management. So let’s jump into the myths here.

Should you avoid gluten?

As a blanket recommendation, this is 99.9% without evidence. It comes from the fact that as an auto-immune condition, Hashimoto’s can overlap with celiac condition and the potential for immune cross-reactivity in between gluten and thyroid tissues . If you think that gluten is making things worse (think: gut problems, joint pain, hard to manage thyroid levels) ask your dr to test you for celiac disease. The evidence simply doesn’t warrant ditching gluten for your thyroid. I really could only find 1 pilot trial of 34 women that indicates some benefit. I will certainly challenge the notion that gluten is usually bad for the thyroid, but also acknowledge it is different. If for you personally, not eating gluten makes you feel good, that’s fine so long as you have support to ensure you’re obtaining the fibre and minerals you desperately need which can be lower whenever your gluten free.

In the event you avoid soy?

This has a bit more theoretical science at the rear of it…but yes, you can still take pleasure in soy foods like soy whole milk, tempeh and tofu if you have reduced thyroid. Soy contains phytochemical substances that can interfere with the uptake associated with iodine by the thyroid when consumed in large amounts – yet this is mostly an issue if you are Lower in iodine. See how vegans need to pay interest here? If you don’t use iodized sodium and eat 3 servings associated with soy a day, it might shift elements! But the main issue is that they can interfere with how thyroid medications work. So take your meds, plus wait AT LEAST 2 hours before taking soy. Also, soy will NOT cause hypothyroidism unless you are usually iodine deficient.

In the event you avoid cruciferous vegetables like kale?

Oh heck simply no! Like soy, the story here is associated with dose and…you guessed it…how’s your own iodine intake? Thiocyanates in cruciferous veggies like bok choy, kale and Brussels sprouts can interfere with thyroid hormone manufacturing if consumed in large amounts (one case study found an elder destroyed her thyroid by eating 2-3 lbs of bok choy A DAY) or if you’re iodine is lower. So I probably wouldn’t juice very much kale everyday on top of eating  Brussels sprouts. But I might absolutely advocate for eating an ordinary size serving of crucifers mainly because those thiocyanates are also healthy for you and an important part of a healthy plant diet. Also, cooking may help reduce the impact of these compounds in your thyroid.


It appears that occasional moderate consuming does not harm the thyroid but presently there isn’t a large degree of study examining this relationship. In one particular 2013 review , it was recommended that alcohol is directly damaging to thyroid cells as well as the regulation associated with thyroid function yet also provided a small protective effect against autoimmune thyroid disease as well as thyroid cancer with moderate drinking. There is certainly more data on how chronic heavy drinking negatively affects the thyroid gland as well as reduces thyroid hormone levels.  If you don’t drink, don’t start…but try to keep it to 1-2 drinks in a sitting and no more than 1-3 times a week.

Other things that will mess with your thyroid meds

Avoid taking iron, supplements with your meds. And save your espresso and tea for later too. In addition, biotin can interfere with the thyroid hormone so prevent supplements for a week before having your labs done.

The results on diet and hypothyroidism

There are a LOT of opinions on the internet – including from health professionals – in regards to the best diet for hypothyroidism. Several of it has little or no basis within actual scientific evidence. This article is really long and we didn’t even obtain a chance to talk much about supplements or the rising role of the microbiome in thyroid disease! So be wary of the ‘strong and wrong’ approach plus instead listen to your body. What meals help you feel your best? Not sure? Begin by experimenting with the (transformative) basics:

  • eat as many entire plant foods as possible
  • drink lots of water
  • get enough rest
  • move the body daily, if even for a quarter-hour
  • Oh, and make use of iodized salt!
