***3 foods thyroid patients should avoid***

Hypothyroidism can cause the body’s metabolism to slow down, Frechman says. That means it’s easy to put on pounds if you aren’t careful. “You want to avoid foods with excess amounts of sugar because it’s a lot of calories with no nutrients,” she says. It’s best to reduce the amount of sugar you eat or try to eliminate it completely from your diet.

Certain Foods Like Fatty Meat And Cruciferous Veggies May Interfere With The Production Of Thyroid Hormone

Hypothyroidism can be a tricky condition to manage, and what you eat can interfere with your treatment. Some nutrients heavily influence the function of the thyroid gland, and certain foods can inhibit your body’s ability to absorb the replacement hormones you may take as part of your thyroid treatment.

Having a thyroid condition is no picnic, but you’re not alone with this health issue. According to the American Thyroid Association, more than 12 percent of the population may end up dealing with a thyroid condition at some point in their lives. And thyroid issues can be sneaky: Of the nearly 20 million Americans living with the disease, as many as 60 percent don’t even realize they have it.

As with many health conditions, some factors are out of your control, including your family history and the environment around you. But diet also plays a prominent role and since you’re the one in charge of your plate, you can decide which thyroid-friendly foods to choose.

Some items on this list may strike you as odd, like fiber and coffee, because for many other diets they’re considered ‘healthy’ or safe picks. You can still enjoy these foods groups, but moderating your intake is a good idea when managing hypothyroidism.

So while there’s no such thing as a “hypothyroidism diet” that will make you well, eating smart can help you feel better despite the condition. Here are nine foods to limit or avoid as you manage hypothyroidism:

Healthy Diet For Your Thyroid

Your thyroid gland governs your metabolism. It does this by producing the thyroid hormones T3 and T4 and releasing them into your bloodstream. If your thyroid is underactive, you are said to have hypothyroidism, whilst having an overactive thyroid is referred to as hyperthyroidism. Before we get into food you should be seeking out to keep your thyroid healthy, let us discuss what can happen if your thyroid is not functioning properly.

Calcium And Iron Supplements

Whether you take these minerals in a multivitamin or alone, calcium and iron supplements may counteract the medication you take to treat your underactive thyroid. These supplements may affect your ability to absorb levothyroxine, the synthetic thyroid hormone found in medications such as Synthroid and Levothroid, according to the Mayo Clinic. “There’s a very strict way to take thyroid medication,” Blum says. You take it the same way every day, at least one hour before food and never with calcium, iron or other minerals. Blum recommends taking your thyroid medication as soon as you wake up and consuming the mineral supplements with food at dinnertime or before bed.

Foods Which Can Inhibit Thyroid Hormone Production

What foods should i avoid with hypothyroidism. Best Diet ...

You may be surprised to find that you can slow down thyroid hormone production by eating certain vegetables. It may sound odd to hear that they could actually slow your metabolism, because vegetables are so healthy. By eating cruciferous vegetables, thats exactly the case. Raw cabbage, turnips, broccoli, Brussels sprouts, and other cruciferous vegetables have high goitrogen content. Goitrogen interferes with the bodys ability to uptake iodine, and it tends to slow the production of thyroid hormones. Foods containing fermented soy, and millet also slow thyroid hormone production. If your thyroid is underactive, you want to avoid these foods.

Whether your thyroid is producing too much or too little in the way of T3 and T4 hormones, this information should help you understand a bit more on how to adjust your diet to improve your thyroid function and metabolism. You will still need to go to see your local doctor or endocrinologist for specific treatment for hypothyroidism or hyperthyroidism. For patients who have a thyroid condition, eating the right diet can be hugely beneficial, as part of a comprehensive treatment plan.

  • Ask your doctor or pharmacist for more information about timing your food and other meds around your thyroid treatment.

Treatment Options For Thyroid Cancer

The treatment of thyroid cancer is decided based on different factors including the type of cancer, extent of spread or stage of the cancer, general health and medical history of the patient. In many cases, thyroid cancers can be cured with treatment.

People with thyroid cancer may have to undergo surgery to remove the thyroid, post which they are often treated with thyroid hormone therapy. Radioactive iodine treatment is also often used after thyroid removal to destroy any remaining thyroid tissue that wasnt removed during surgery. Other treatments for thyroid cancer include radiation therapy, chemotherapy, targeted drug therapy and supportive care. Irrespective of the treatments used by the patients, good nutrition is important to help them build up strength and manage the effects of the cancer and the treatment.

Nutrition for Hypothyroidism: What to Eat and What to Avoid

Sugar & additives

Additives like gums, food dyes, and sugars do not promote healing. First, let’s look at the different types of sugar.


Sucrose is what you’d call “table sugar.” Commonly extracted from cane sugar or sugar beets, it’s found naturally in various fruits, veggies, and grains, as well as many processed foods.


Sometimes referred to as “fruit sugar,” fructose is derived from fruit. Fructose also comes from honey, agave, and most root vegetables. Like sucrose, it is in many processed foods in the form of high-fructose corn syrup.


Glucose is the term for blood sugar. It’s your body’s preferred carb-based energy source because it converts quickly and easily into energy.

There are over 60 different names for sugar! Some are more obvious than others, like brown sugar, corn syrup, and cane sugar. Others are trickier to identify, such as Muscovado and Turbinado, which sound more like vacation destinations than sugar types.

Not all sugar is created equal. Some forms of sugar affect your blood glucose differently than others. This difference is called the glycemic index, a system that ranks foods on a scale from 1 to 100 based on their effect on blood sugar levels.

For those with hypothyroidism or Hashimoto’s, it’s essential to know where refined sugar might be hiding. Too much can lead to increased inflammation, blood sugar imbalances, leaky gut, and hormone function disruption.

Intake Of Starchy And Sugary Foods May Increase The Risk Of Thyroid Cancers

Researchers from the Istituto di Ricerche Farmacologiche Mario Negri Milan, Italy analyzed data from a case control study conducted in Italy between 1986 and 1992 involving 399 thyroid cancer cases and 616 controls and found that starchy and sugary foods which are known to have high levels of glycemic index and glycemic load may increase the risk of thyroid cancers.

What Foods Are Bad For Thyroid Function

Now that weâve highlighted foods to boost thyroid function, letâs focus on foods to avoid if you have a thyroid condition.

If you have hypothyroidism

In general, stay away from foods that are high in soy protein, since they may interfere with your bodyâs ability to absorb replacement thyroid hormones.

You may have also heard that you should avoid cruciferous vegetables such as spinach, kale, cabbage, cauliflower, broccoli, turnips, and Brussels sprouts.

Itâs important to know that these foods, by themselves, probably wonât harm your thyroid function. However, they are considered goitrogenic foods because they affect your thyroidâs ability to absorb iodine, which can lower thyroid hormone production and increase your risk for goiters.

What does that mean for you? If youâre not getting enough iodine in your diet, or if you know you have low iodine levels, you may want to talk to your healthcare provider about avoiding these vegetables.

But if you have hypothyroidism, or are at increased risk for goiters due to family history, you donât have to avoid these vegetables entirely. Instead, try to mix up the vegetable servings you eat each day, so you arenât getting a whopping intake of goitrogens in any one meal. Also note that if you juice these vegetables, youâll vastly increase their concentration of thiocyanates, which is the chemical in goitrogenic vegetables that interferes with your thyroid gland function.

Having a healthful diet rich in fruits, vegetables, filling proteins, and healthy fats can help manage weight and boost well-being. These foods are also rich in nutrients and may help people feel fuller for longer.

In addition, regular moderate- to high-intensity aerobic exercise and strength training can help boost metabolism and promote weight loss. Staying active can also improve levels of energy and the quality of sleep.

In addition, a person may notice a little weight loss typically under 10% when they take medication to treat hypothyroidism.

How Can I Treat My Thyroid Problem Naturally

If a thyroid test and a physicianâs evaluation indicates youâve got a thyroid condition, itâs important to follow the medical advice of your healthcare provider. It isnât possible to heal your thyroid solely by making dietary changes.

But this doesnât mean you canât make lifestyle changes that will naturally boost your thyroid health and help manage a thyroid dysfunction. First and foremost, focus on eating a nutritious diet, since this will keep delivering benefits even after your thyroid hormone level has balanced out due to medical treatment.

Also, since both hypothyroidism and hyperthyroidism change the way your body metabolizes food, look to increase your fiber intake, as this can improve your digestion. Fiber-rich foods include whole grains, fruits, and veggies. Make sure to get plenty of nutrients, and look to proteins from lean sources such as fish, or plant-based options like beans or nuts. You should also eat healthy fat sources, such as olive oil or omega-3 fatty acids.

Of course, managing your thyroid health naturally also means avoiding unhealthy foods. Specifically, try staying away from âbad fatsâ like trans fats, which are typically found in products like margarine, processed foods, and hydrogenated oils.

Cruciferous Vegetables Like Broccoli And Cauliflower

Cruciferous vegetables, such as broccoli and cabbage, are full of fiber and other nutrients, but they may interfere with the production of thyroid hormone if you have an iodine deficiency. So if you do, its a good idea to limit your intake of Brussels sprouts, cabbage, cauliflower, kale, turnips, and bok choy, because research suggests digesting these vegetables may block the thyroid’s ability to utilize iodine, which is essential for normal thyroid function. However, according to the Mayo Clinic, you would need to consume a significant amount of cruciferous vegetables for it to truly impact iodine uptake.

If you have been diagnosed with both hypothyroidism and iodine deficiency, there are some things you can do to make these vegetables less harmful. Cooking them can reduce the effect that cruciferous vegetables have on the thyroid gland, and limiting your intake of these vegetables to 5 ounces a day may help as well, since that amount appears to have no adverse effect on thyroid function.

Excess Fiber From Beans Legumes And Vegetables

Getting enough fiber is good for you, but too much can complicate your hypothyroidism treatment. The government’s Daily Guidelines for Americans currently recommends that adults up to age 50 should take in 25 to 38 grams of fiber a day. Amounts of dietary fiber from whole grains, vegetables, fruits, beans, and legumes that go above that level affect your digestive system and can interfere with absorption of thyroid hormone replacement drugs.

If you’re on a high-fiber diet, ask your doctor if you need a higher dose of thyroid medication. Your maintenance dose may need to be increased if you aren’t absorbing enough medication.
