How to Take Care of Your Thyroid on a Plant-Based Diet


Our thyroid is one of the most important parts of our endocrine system; this glands regulates everything from our mood, our weight, our body temperature, metabolism, and even digestion. The confusing part about understanding if you have a thyroid problem is also realizing that all of these health issues can be both a cause and effect on the thyroid. One of the most “testy” glands in the human body, it’s essential to our overall wellness and is constantly changing to adapt to our current state of health. It acts as a modulator but is also very susceptible to our actions and as a result, it can become out of balance quickly.

What Our Thyroids Do on a Day to Day Basis

Our thyroid is a butterfly-shaped glands that is found in the front of our throats right below our Adam’s apple (the larynx). It’s responsible for regulating our thyroid hormones on a day to day basis. But what do those hormones do? There are three thyroid hormones, two of which are commonly known as T3 and T4. The other is lesser known, yet still important and called calcitonin. These hormones control the body’s metabolic rate as well as contribute to heart function, digestive health, muscle control, bone maintenance, and even brain development and mood. The release of these hormones are completely controlled by the TSH (thyroid-stimulating hormone) that’s produced by the pituitary gland. They are utilized in the body to assist with energy and also affect how other hormones in the body work as well.

Possible Thyroid Problems

It’s estimated that 30 million people have a thyroid disorder of some kind. Many people suffer from underactive thyroid, known as hypothyroidism, while others suffer from overactive thyroid disorder, or hyperthyroidism. Both can be detrimental to one’s health and cause a host of other health issues to occur as a result. Hypoythyroidism is most common, especially in women. It can lead to weight gain, a slowed metabolism, low energy, depression, digestion upset, mood problems, joint pain, poor memory, muscle stiffness, headaches and more. It often leads to autoimmune disease disorders known as Hashimoto’s and Graves disease due to the way the thyroid affects all major parts of the body. Hypothyroidism can cause anxious-like energy, problem gaining weight, higher body temperatures, trouble sleeping, and overactive digestion.

The reasons for a thyroid disorder are hard to pinpoint since many things can cause an imbalance quickly. A poor diet, too much or too little exercise, consistent stress, trauma, a food allergy, lack of rest, metabolic disorders, other hormone disorders, medication and birth control pills, and so many other things can affect one’s thyroid. Many women in their early 20’s and 30’s begin to show thyroid problems, but it can occur at any age, even babies and young children.

Nutrients Needed for a Healthy Thyroid

One of the main nutrients needed for a well-functioning thyroid is iodine, yet too much can actually pose a problem and lead to hypothyroidism, therefore it’s crucial not to just assume that taking an iodine supplement will fix the issue. Other nutrients necessary for a healthy thyroid (and metabolism) are B vitamins, good clean sources of fat, substantial amino acids (protein), and a variety of fruits and vegetables that supply high-quality vitamins and minerals. Though many animal foods contain B vitamins and some even have good sources of fat, such as fish, eating these foods are not necessary to maintaining a healthy thyroid. In fact, though fish is a natural source of iodine, it’s also dangerously high in mercury, with more and more research being found everyday just how toxic fish is to our bodies. Mercury can cause not only problems to our thyroid, but also permanent neurological damange. And while foods like eggs and lean poultry supply B vitamins and are a better option than red meat, they are overall not the best source of nutrition for long-term health.

How to Take Care of Your Thyroid on a Plant-Based Diet

Eating a diet that supports your thyroid is completely possible to do without animal products. The key thing to remember is to stay away from processed foods as much as possible because remember: Whatever you put in your body is used as either fuel or has to be circulated through the organs to be detoxified because it’s a foreign agent to the body. This slows down all the body’s intended purposes, including producing thyroid hormones. Your body doesn’t recognize chemicals, additives, hormones, pesticides and excessive amounts of processed salts and sugars. It needs real food.

Here are some key nutrients to focus on and the best sources: 



One of the best sources of iodine in a plant-based diet are blue-green algaes and kelp, which is where fish obtain their omega’s and their iodine from. Spirulina is one type of blue green algae and supplies plentiful amount of iodine with 10 percent of your daily needs. In conjunction with a well-balanced diet, one would be able to get enough iodine without worrying about an overdose in this single nutrient. A teaspoon a day in a smoothie would be a perfect amount to add just enough. Plus, it’s also an incredible source of food-based iron which is needed for optimal metabolism. Raw, unrefined pink sea salt is another excellent source of natural iodine from the earth and also contains other alkaline minerals such as magnesium, potassium, and sodium your metabolism needs to function at its best. Too little quality sodium and too much refined sodium can lead to blood pressure problems, metabolic disorders, and also thyroid disorders. Skip iodized (highly refined) processed salts and use real salt from the earth instead. 

B Vitamins


B vitamins assist with metabolism, energy levels, digestion, mood health, and thyroid health. They are found abundantly in plant-based foods. Some of the best sources are: avocados, greens, sweet potatoes, broccoli, bananas, figs, nuts, seeds, spirulina, coconut, whole grains, sprouted grain (flourless) breads, beans, legumes, and nutritional yeast. Be sure to take a vitamin B12 supplement, preferably a sublingual or liquid form that is absorbed immediately in the bloodstream. Lack of vitamin B12 can also cause thyroid problems, but a supplement ensures everyone gets enough.

Vitamin D

Vitamin D acts as a hormone in the body; it plays a part in your mood, digestive, bone, blood, heart, and thyroid health. A shortage of vitamin D can lead to bone loss, digestion problems, depression or just general sadness, and fatigue. It’s also directly linked to Hashimoto’s disease, one of the autoimmune disorders tied to hypothyroidism, but is not yet known to be a direct cause or just a side effect. Either way, everyone should be obtaining optimal vitamin D levels as much as possible. Don’t rely on fortified foods (or even milk) as your go-to source; these foods contain the form of vitamin D known as vitamin D2, not vitamin D3, the optimal form. Vitamin D3 is the easiest for your body to absorb and use efficiently. It comes from the sun, therefore the best way to get enough is to get 15 minutes of sunlight daily. If you live in a cloudy location or can’t get outside daily, do look into a supplement. Be sure to purchase vitamin D3 (not vitamin D2) and double check that it’s plant-based so you’re not taking in lanolin (sheep’s skin) or fish oil found in most vitamin D3 supplements.



You may have heard of this mineral being good for your skin, hair, or being great for men’s health — and you’d be right! Selenium is great for your skin and hair, along with men’s prostate health, but it’s also crucial to a healthy metabolism and thyroid. It’s primarily found and stored in the thyroid gland where it’s used to assist with the enzymatic breakdown of the thyroid hormones so they can be used by their body. Because when you think about it, even if these hormones are being produced, if your body can’t use them efficiently they aren’t going to do you much good. Selenium also supports the immune system and with fertility in both men and women. The easiest way to get enough? Eat one Brazil nut a day; they have over 100 percent of your daily needs in just one nut. If you’re not a fan of the taste, just toss them in a smoothie; you’ll never taste them! Though seafood offers natural selenium too, no other food rivals that of Brazil nuts. As a bonus, it’s easy to digest and has 2 grams of fiber plus plenty of healthy fats your body also needs for a optimal thyroid function.

Good Fats


If you’re all about a fat-free diet for too long it could lead to thyroid problems. One reason being that healthy fats, specifically good saturated fats (found in coconut, cashews and cacao) are all necessary for a healthy thyroid. They help prevent high blood sugar levels that can lead to insulin swings which can alter metabolic health, increase stress hormones, and lead to hypothyroidism as a result. Try your best to avoid animal products with cholesterol since these have consistently been linked to other health issues like heart disease. You can get plenty of good saturated fats in your diet from raw coconut meat or raw coconut products (butter, shreds, flour), along with nuts like cashews that have a higher amount of saturated fats than some other nuts. Just a few tablespoons of these fats a day is all you need to support your body long-term. Other healthy sources of good fats to include in your diet include: almonds, avocados, dark chocolate (choose at least 85 percent cacao or higher or raw cacao), seeds, walnuts, and pecans. Avoid vegetable oils and try to only use coconut oil or olive oil if you choose to use oil at all.

What to Avoid to Take Care of Your Thyroid


Excess caffeine, processed food, added and refined sugar, alcohol, and unhealthy fats can all cause problems with the thyroid and prevent optimal absorption of thyroid hormones in the body. There is also a great deal of controversy surrounding soy and cruciferous veggies due to their effects on the thyroid. The reason for this is because these foods contain natural goitrogenic properties. Goitrogens are a substance that prevents the use of thyroid hormones in the body. Know that though these foods do contain goitrogens, their effects on thyroid health only pose a negative problem if a great deal of them are eaten consistently on a day to day basis. It’s always best not to consume too much of any food, including these.


Rotate your greens in your green smoothies, eat different sources of protein without only relying on soy, and eat plenty of vegetables, fruits, nuts, seeds, and a variety of beans and legumes if you tolerate them well. A well-varied diet is a key part in taking care of your thyroid long-term. There is also not enough research out yet that proves soy and cruciferous vegetables (kale, broccoli, cabbage, cauliflower) are substantially harmful in small to moderate amounts. Use your discretion with these foods; if they make you feel great, keep eating them but if you notice problems, be sure to eat other healthy plant-based options instead. 

Hopefully now you know what you need to thrive on a plant-based diet, not just for your thyroid but for long-term health too. Be sure you explore our Plant-Based Nutrition Guide which can answer more health questions you may have. All in all, eat more plants, real food, and get enough movement, sunlight and try to manage your stress daily. These are the best things you can do for your thyroid and overall health.

If anyone should still be grateful to God for the gift of life, that person should be me. Men and Women in this page, Faith Ristus is my name, I want to let the whole world know how I was cured of my Hepatitis B by God through the help of Herbal Dr Uwadia Amneifo. I was ill and diagnosed of Hep B after successfully undergoing appendicitis operation. After my doctor diagnosed me of Hep B, he said this virus has no cure and that I have to be careful not to allow anyone have direct contact with my blood. I have husband and kids at home, and anytime I come from work they come to me and I carry my kids on my body and sometimes they even sleep laying on my body so I begin to wonder how I can now start to avoid my kids and my husband for them not to contract this virus. I was given medicine like Lamivudine (Epivir-HBV, Zeffix, or Heptodin) and others to curb it but my conditions remain the same, and instead I would only eat and sleep after taking the pill, and this pill was too expensive for me. My health began to deteriorate on a constant basis and I was almost beginning to see my grave. For this reason I was prompted to do a search on the internet to see how I could help myself. I ran into a blog where I saw a testimony of a woman named Rash Hansell where she testified of how she as cured of Hypothyroidism with the use of roots and herbs prepared and shipped to her by Herbal Doctor Uwadia Amenifo. After carefully studying her testimony, I decided to take the contact details of the herbalist and immediately I maintained communication with him. He replied my message via his email and told me he got my message for the herbal cure of Hep B and he assured me that my cure is certain with his herbal mixture. He was so confident that I was so convinced just in his confidence. So we made necessary arrangement, and he prepared the herbs and shipped it to me. Just as he directed me to use it I really did. Behold it was as if he gave me magic medicine. My body system began to positively react to his medicine and in just less than three weeks, I was totally cured. I told him before he cured me that if he cures me, I will tell the whole world about his herbal medicine, and now I am cured so I am fulfilling my promise to him. Please if you are out there and still suffering from Hep B or other diseases, please I want you to in a hurry contact Herbal Doctor Uwadia Amenifo now and give him a try. His contacts are Email ([email protected]) his number is (+2349052015874), His website is http://druwadiaherbalhome.simplesite.com/ God bless you all.

Just FYI - there is a typo - this should actually be Hyper not Hypo... Hypothyroidism can cause anxious-like energy, problem gaining weight, higher body temperatures, trouble sleeping, and overactive digestion

03 Feb 2017

Actually, it is hypothyroidism that causes fatigue, trouble losing weight, low body temperature... Hyperthyroidism causes the symptoms you listed above.

I'm diagnosed with Graves Disease.. a hyperthyroid.. and at the same time I'm vegan, so I naturally eat a lot of soya-products but I read somewhere that soya is the worst you can eat when you got an overactive thyroid and so is bread, cause thyroidproblems often leads to intolerance to gluten, which I have.. Its really a challenge with food when you're both a vegan and having a hyperthyroid AND is allergic to gluten.. But THANKS for the article

Neither have I and they flatly refuse that anxiety, panic attacks or depression go hand in hand with thyroid problems. I had mine ablated with RAI six years ago due to Graves' disease.
