Your thyroid might not be something you think about daily, but it plays a huge role in keeping your body running smoothly. This small, butterfly-shaped gland in your neck is in charge of regulating your metabolism, energy levels, and even how well your body uses nutrients. If it’s not functioning properly, you might feel constantly drained, struggle with unexpected weight gain, or even experience mood swings.
While medication and lifestyle choices play a role in thyroid health, what you eat is just as important. Certain foods help reduce inflammation, support hormone production, and keep your thyroid functioning at its best. Whether you’re managing a thyroid condition or just want to keep things balanced, adding the right nutrients to your diet is a smart move. Here are some of the best foods to support thyroid health and why they deserve a spot on your plate.
Eggs
Packed with iodine and selenium, eggs help your thyroid stay on top of its game. The yolk is where most of these nutrients are found, so skipping it means missing out on a natural boost for hormone production. Choline in eggs also plays a role in thyroid regulation, supporting overall gland function. Enjoying a whole egg daily is a simple way to nourish your thyroid and keep your metabolism in check.
Yogurt
Dairy products are a great source of iodine, and yogurt is one of the best options for a daily dose. A single serving can provide nearly half of your iodine needs, helping to keep thyroid hormone production stable. Probiotics in yogurt also support gut health, which is closely tied to thyroid function. For the best benefits, opt for plain, unsweetened yogurt to avoid unnecessary additives.
Soy
Soy often gets a bad reputation when it comes to thyroid health, but in moderate amounts, it’s perfectly fine. It contains isoflavones, which can interfere with iodine absorption if consumed in excess, but this only becomes an issue with very high intake. For most people, eating tofu, soy milk, or edamame in normal portions won’t negatively impact thyroid function. If you’re getting enough iodine in your diet, soy can be a healthy protein source without causing problems.
Berries
Antioxidants in berries help protect the thyroid from oxidative stress, which can contribute to inflammation and hormonal imbalances. Blueberries, strawberries, and blackberries are loaded with vitamins and minerals that support immune function and overall gland health. Since thyroid disorders are often linked to immune system dysfunction, eating berries regularly can be an easy way to offer extra protection. Their natural sweetness also makes them a great alternative to sugary snacks.
Brazil Nuts
Just a couple of Brazil nuts a day provide all the selenium your thyroid needs. Selenium plays a key role in converting inactive thyroid hormones into their active form, keeping metabolism and energy levels steady. It also helps reduce inflammation in the gland, lowering the risk of autoimmune thyroid conditions. Since too much selenium can be harmful, sticking to just a few Brazil nuts is the best way to get the benefits without overdoing it.
Cruciferous Vegetables
Broccoli, cauliflower, and Brussels sprouts contain compounds that, in large amounts, might interfere with thyroid function, but this only applies to excessive raw consumption. When cooked, these vegetables lose most of those compounds while still delivering fiber, vitamins, and antioxidants that benefit the thyroid. Regular servings of cooked cruciferous vegetables support detoxification and hormone balance. There’s no need to avoid them—just enjoy them in moderation and mix them into a well-rounded diet.
Shellfish
Lobster, shrimp, and mussels are all excellent sources of iodine and zinc, both essential for thyroid hormone production. Zinc also plays a role in preventing hair loss and fatigue, common symptoms of thyroid dysfunction. Eating seafood a few times a week helps maintain the right balance of these nutrients without going overboard. If you’re not a fan of shellfish, other seafood like scallops or clams can also do the trick.
Fish
Fatty fish like salmon, tuna, and sardines provide iodine and omega-3 fatty acids, which help reduce inflammation and support thyroid health. A well-functioning thyroid needs adequate omega-3s to keep hormones balanced and metabolism running smoothly. Leaner fish like cod also deliver a solid amount of iodine without excess calories. Including fish in your diet a couple of times a week is an easy way to support long-term thyroid function.
Beef
Zinc deficiency is linked to hypothyroidism, and beef is one of the best dietary sources of this crucial mineral. A moderate serving of beef helps your thyroid produce hormones efficiently and supports immune function. Since the body doesn’t store zinc well, getting enough through food is important for steady hormone regulation. Choosing lean cuts ensures you’re getting the benefits without too much saturated fat.
Seaweed
If you need an iodine boost, seaweed is the way to go. It provides one of the richest sources of natural iodine, helping the thyroid produce hormones effectively. However, too much iodine can be just as bad as too little, so it’s best to consume seaweed in moderation. Adding nori to sushi or tossing some wakame into soup is a simple way to get the right amount without overloading your system.
Pumpkin Seeds
Rich in zinc, pumpkin seeds play a direct role in thyroid hormone production. A handful of these crunchy seeds provides a nutritious snack while helping maintain proper thyroid function. They’re also packed with magnesium, which supports energy levels and helps regulate stress, two factors that influence thyroid health. Sprinkling them on salads or oatmeal is an easy way to incorporate them into your daily diet.
Chia Seeds
Packed with omega-3 fatty acids and selenium, chia seeds help lower inflammation and promote thyroid function. Their antioxidants work to reduce oxidative stress, which can negatively impact the thyroid. These tiny seeds are an easy addition to smoothies, yogurt, or oatmeal to support overall thyroid health.
Legumes and Beans
Loaded with zinc and fiber, legumes and beans contribute to thyroid function and digestive balance. Fiber helps prevent constipation, a common issue linked to thyroid disorders. Chickpeas, in particular, offer digestive support while keeping metabolism steady. Eating a variety of beans can improve gut health and maintain stable energy levels.
Whole Grains
Oats, quinoa, brown rice, and sprouted grain bread are packed with fiber, aiding digestion and promoting a healthy metabolism. Unlike refined grains, they require more energy to break down, which benefits thyroid function. Choosing whole grains over processed options can help maintain steady energy levels. Including them in your meals supports long-term thyroid health.
Avocado
Packed with healthy fats, fiber, and antioxidants, avocados nourish the thyroid while promoting hormone balance. Their antioxidants help fight oxidative stress, which can interfere with thyroid function. The fiber content supports digestion, keeping everything running smoothly. Adding avocado to meals is a simple way to keep your thyroid and body in good shape.
Sweet Potatoes
A great source of beta-carotene, which converts to vitamin A, sweet potatoes support thyroid health and immune function. They also contain fiber and antioxidants that contribute to overall well-being. Their natural sweetness and versatility make them easy to incorporate into meals. Eating them regularly can help maintain thyroid balance.
Cassava
A staple in many cuisines, cassava is a starchy root vegetable that should be consumed in moderation by those with thyroid concerns. In large amounts, compounds in cassava may interfere with thyroid function. However, cassava-based foods like flour, chips, and tortillas can be enjoyed in balanced portions. Being mindful of intake is key for thyroid health.
Dark Chocolate
With 70% to 85% cacao, dark chocolate is rich in magnesium, fiber, and antioxidants that help shield thyroid cells from oxidative stress. Free radicals from toxins and daily stressors can negatively impact thyroid health, but cacao’s nutrients combat this damage. A moderate serving of dark chocolate can be a beneficial and enjoyable part of a thyroid-friendly diet. Opting for high-quality dark chocolate ensures the best nutritional benefits.
