Thyroid conditions can be addressed in many ways, including lifestyle changes. In addition to medical care, try these 5 foods to help thyroid function!


Sea Vegetables

Sea vegetables are some of the only natural dietary sources of iodine1, which is essential for creating thyroid hormones. If your body is deficient in iodine, you will be inhibiting proper thyroid function. So go ahead and indulge in that nori with your sushi wrap! If you don’t like the taste of seaweed, eating it in your miso soup is a great way to hide the flavor and still reap the benefits. You can also add dulse and wakame flakes into pureed soups or stocks for more umami flavor.

Super Greens

While green veggies are great, try some of the stronger superheroes like chlorophyll, chlorella and spirulina. All of these are easily found at healthy grocers, online or available through your physician. Liquid chlorophyll is actually tasteless, and a little goes a long way. I like to add 10-12 drops of chlorophyll into my 32 oz water bottle with a couple slices of citrus. These greens are super alkalizing and create a better internal environment for energy production and proper thyroid function2.

Selenium Superheroes

Selenium is essential for thyroid function because it is used in the formation of hormones. The plant-based sources that are highest in selenium are Brazil nuts and spinach. Eat just 2-5 Brazil nuts a day to keep selenium levels healthy. While spinach is a good source, our soil is becoming more and more depleted in selenium so make sure it is organic or home-grown for maximum nutrition. You can also find selenium in fatty fish and meats.


The jury is out on cruciferous veggies and goitrogens because of their potential to block iodine absorption, but there is actually very little evidence that shows they can cause goiter. You’d have to eat pounds of bok choy at every meal, every day to create a real problem. With a good balance of calcium, vitamin D, selenium, and iodine, there should not be any reason you can’t eat normal servings of the superfood broccoli3. Besides the antioxidants and other nutrients in broccoli, it is the best plant source of vitamin D, which people with thyroid issues are typically very deficient in.


A recent study has shown that people with hypothyroidism have higher levels of free radicals4. The best way to attack free radicals? Antioxidants, and that’s why berries are the best! Berries are packed with antioxidants, low in sugar and high in fiber, making them the perfect snack food. Try throwing them into your oatmeal, yogurt, or try putting them in your water with some fresh herbs like mint or basil.
