Broccoli and other cruciferous vegetables contain goitrogens that interfere with the production of the thyroid hormone if you have an iodine deficiency. They can also be responsible for blocking the thyroid’s ability to utilize iodine, which is essential for normal thyroid function.
Tuna, swordfish, shark, kingfish, mackerel, as well as other predator fish usually contain more mercury than smaller fish. Too much mercury causes a wasting or decrease in the size and/or function of the thyroid.
While the thyroid gland does need a certain amount of iodine to perform its essential function, too much iodine can damage the thyroid and make you feel sluggish. It is advised that iodine levels be kept between 100 to 200 mcg/L per day.
Raw kale can steal the iodine from the thyroid and also contains goitrogens. Goitrogens are compounds that may interfere with the function of the thyroid gland. Eating foods with goitrogens can aggravate an already damaged thyroid but avoiding them can help restore it.
Hot Dogs and Deli Meats
Most processed meats such as hot dogs and deli meats usually contain additives that aggravate the thyroid gland. They also have high amounts of sodium that can put patients with hypothyroidism at a greater risk of high blood pressure.
Calcium and/or Iron Supplements
Yes, your body needs both iron and calcium; however, too much of either can counteract the medications prescribed to treat hypothyroidism such as synthetic thyroid hormones or thyroid extract supplements.
Heated Food in Plastic Containers
The thyroid is part of the endocrine system and endocrine disrupters are in everyday plastics such as bottles, food, and containers with BPA. Also, these foods have high amounts of sodium added which can increase chances of high blood pressure in hypothyroidism patients.
High-Fat and/or Fried Foods
Many fried foods are high in fat which can lead to inflammation of the thyroid. Fats have been found to disrupt the body’s ability to absorb thyroid hormone replacement therapies as well as interfere with the thyroid’s ability to produce the hormone.
Cookies, chips, crackers, and other snacks usually contain high-fructose corn syrup. This can cause hormonal balances and weight gain in a healthy person, let alone someone with an unhealthy thyroid gland.

While soy milk is typically a wonderful alternative to dairy, it can be harmful to the thyroid if you suffer from hypothyroidism.

Whole Wheat Bread
Whole wheat bread is another concerning food that you may want to steer clear of if you’ve been diagnosed with hyperthyroidism. The gluten found in bread (and pasta and rice) can easily irritate and alter the absorption of thyroid medicine.

There are pros and cons to rice. Rice, like all whole-grains, is extremely fibrous and can help with bowel regularity. However, the fiber in rice can also interfere with your thyroid hormones. So, if you’re going to eat rice, be mindful of your portion size.
Caffeine can have major implications on your health, so be aware of your daily caffeine intake. Coffee, the ultimate caffeinated beverage, doesn’t just wake you up and energize you. It can also increase your blood sugar levels and impact the levels of your thyroid hormones.
Tofu and Edamame
Soy is one of the main ingredients in foods like tofu and edamame. So, as mentioned before, it’s important to understand the concern over its negative effects. Many health professionals recommend watching soy consumption and waiting four hours after eating soy products to take thyroid medicine.
Soda and Energy Drinks
Soda and energy drink consumption can cause significant health problems if you have hypothyroidism. The sugar in these beverages can upset your thyroid and should be avoided, if possible. If you still want to drink these beverages, try looking for the diet and no sugar options.

However, you’ll want to watch your intake of sweet potatoes so that you don’t block your thyroid’s absorption.
While the majority of foods interfere with hypothyroidism medicine, this food actually appears to trigger the disease. Peanuts and peanut butter contain compounds called goitrogens. These can enlarge the thyroid gland and cause health issues. Millet and pine nuts should also be avoided.
Because pasta is a grain and contains gluten, it’s another worrisome food. Eating pasta in moderation is your best bet. If that doesn’t help, you may want to try a gluten-free diet to prevent further issues with your thyroid.

Fats disrupt thyroid hormone replacement medicines because they aren’t able to correctly absorb. Reduce the amount of times you eat out every week or month to lower your fatty food intake.
Corn is one of the more discussed foods. Many people debate whether or not it’s okay to eat for those with thyroid issues. The trouble with this vegetable is that corn is cross-reactive, meaning that it’s technically gluten-free, but it causes the body to react as if it’s eaten gluten.
Seeds with high oil contents are sometimes used to make vegetable oils. Sunflower, sesame, flaxseed, and many others are often used. Once they are turned into vegetable oils, they become troublesome to your thyroid. These oils block the release of hormones and block cells from using the thyroid correctly.
Most organ meats—like kidneys, hearts, or livers—contain lipoic acid This acid compound works against thyroid medication by affecting the way they work. If this happens, you may be unintentionally sabotaging your health and wellness.
While eggs are commonly considered to be good for your thyroid, that’s not completely true. Egg whites are good for your thyroid. They’re low in iodine and can be beneficial to your health. Egg yolks aren’t so good for your thyroid. They’re high in iodine and can worsen your hypothyroidism.
Fish and Shellfish
You’d be surprised to know how bad seafood can be for you if you have hypothyroidism. Fish, shellfish, and seaweed contain large amounts of iodine. While iodine is necessary for a healthy thyroid, too much iodine has the potential to worsen your hypothyroidism.
