The saying “you are what you eat” is frequently used in conversations about health and the relationship between food and the body. Therefore, eating an unhealthy diet can have significant consequences and increase a person’s risk of developing heart disease, stroke, type 2 diabetes, and even thyroid dysfunction, which is now very common.

For most people, the thyroid hormone acts as an invisible essential friend, regulating their energy levels, metabolism, body temperature, mood, heart rate, and blood pressure to keep their bodies functioning as they should. Unfortunately, for many, thyroid dysfunction is a severe issue.

Making the right food choices is crucial in treating thyroid disease and most other conditions. This article will guide you on which foods to avoid to treat thyroid disease, but before diving into the diet part, let’s first take a quick look at the thyroid gland to comprehend this vital organ better.

An Overview of the Thyroid Gland

The thyroid gland is situated at the base of Adam’s apple in the front of the neck. It has two lobes on either side of the windpipe and is shaped like a butterfly.

The thyroid gland produces Thyroxine (often referred to as T4) and triiodothyronine (referred to as T3). Thyroxine and triiodothyronine are collectively referred to as the thyroid hormones. It controls the following.

  • The body’s metabolic rate
  • Controlling heart, muscle, and digestive function
  • Controlling brain development
  • Maintain bone density

The thyroid gland typically produces the correct number of hormones to maintain a healthy and balanced metabolism in your body. However, there are several thyroid illnesses, most of which have to do with thyroid hormone production.

The thyroid gland either generates too much hormone, referred to as hyperthyroidism, or not enough hormone, known as hypothyroidism. As a result, they cause your body to use energy more quickly or slowly than it should.

Although medicine is the main course of action, research indicates that a sufficient amount of iodine from food is necessary for the thyroid hormones to operate correctly. Therefore, lifestyle changes, adopting healthy eating habits, and avoiding unhealthy foods can help with thyroid symptoms and function.

The HealthifyMe Note

Thyroid hormones are released into the blood by the thyroid gland. Both hypothyroidism and hyperthyroidism can occur when the thyroid gland is not functioning correctly. Either of these diseases may impact the typical operation of many bodily functions. You can make a few dietary adjustments to restore your thyroid hormone levels to normal. For thyroid disease, a healthy diet is essential. There aren’t many guidelines to follow because there isn’t a defined “thyroid diet,” but you should be aware of the items you should avoid.

Foods to Avoid for Thyroid Patient

You should avoid specific foods to maintain a healthy thyroid, whether diagnosed with hyperthyroidism or hypothyroidism.

Listed below are some foods that one must avoid during hyperthyroidism:

Cruciferous Vegetables

You may have heard that those with thyroid disorders should avoid goitrogen-containing foods since they may interfere with the production of thyroid hormones. Even though some veggies are healthy, some cruciferous vegetables are high in goitrogens.

Despite being high in fibre, they may prevent the synthesis of thyroid hormones, leading to hypothyroidism. Avoid eating broccoli, spinach, cabbage, and cauliflower if you have thyroid issues.

According to a study, these veggies may prevent the thyroid from using iodine, which is necessary for healthy thyroid function, when they get digested.

It also prevents the thyroid from absorbing iodine, essential to function correctly. However, cooking goitrogen-containing meals lowers their goitrogenic activity, making them safer for hypothyroidism sufferers. However, to generalise, one with hypothyroid should avoid consuming significant quantities of any goitrogenic foods.

Fatty or Fried Meals

Food that has been too fried contains fat that may prevent the body from adequately absorbing thyroid hormone replacement therapy. Additionally, fats might harm the thyroid’s capacity to make the hormone thyroxine. Furthermore, those with slow metabolisms may find it difficult to digest fatty foods high in calories.

As a result, it might result in significant weight gain in hypothyroidism. Therefore, foods containing too much-saturated fat should be avoided, such as fried foods or butter, mayonnaise, or margarine.

Soy Containing Food 

A typical food allergy that might affect thyroid function is soy. Goitrogens, chemicals that can obstruct thyroid hormone production, are present in soy.

Additionally, phytoestrogens, which can mimic the effects of oestrogen interfere with the thyroid gland’s regular operation, are present in soy products. According to a study, the soy component isoflavone may harm your thyroid’s health.

It is better to avoid soy if you have a soy allergy or sensitivity altogether. Also, this applies to tofu, tempeh, soy sauce, soy chunks, soy milk, and any other item containing soy protein. In addition, if you have Graves’ illness or hypothyroidism, please avoid soy because of its goitrogenic and estrogenic effects.


One of the most prevalent food allergies is gluten; many people with thyroid issues are also sensitive to it. It’s crucial to avoid meals containing gluten if you have a thyroid issue. Wheat, rye, and barley all contain the protein gluten. It makes pastry dough rise and gives bread its chewy texture.

Many manufactured foods also contain gluten as a stabiliser or thickening agent. Celiac disease patients are entirely intolerant of gluten. You could still be sensitive to gluten even if you don’t have celiac disease.

You may encounter symptoms including weariness, brain fog, joint pain, and digestive issues if you have a thyroid condition and consume gluten-containing foods. Therefore, it is advisable to stay away from gluten-containing meals.


Caffeine-containing foods and beverages, such as coffee, tea, soda, and chocolate, can exacerbate hyperthyroidism symptoms and bring apprehension, uneasiness, irritability, and a rapid heartbeat.

If coffee has this effect on you, it would be advisable to steer clear of it entirely or only drink it occasionally. Instead of drinking coffee, think about switching to flavoured water, hot apple cider, or natural herbal teas.

Excess Iodine Food

Since hyperthyroidism already produces a lot of iodine, too much is dangerous. On the other hand, iodine overload is caused by hyperthyroidism because the body already has enough iodine. Further, severe thyroid problems can result from overload.

A study found that eating too many iodine-rich or iodine-fortified foods could either lead to hyperthyroidism or, in some cases, exacerbate it. According to the National Institutes of Health, the iodine content in a teaspoon of iodised salt is 304 micrograms (mcg).

Seafood is particularly rich in iodine. An iodine intake of 150 mcg (0.15 mg) per day is advised by the National Institutes of Health (NIH). When eating a low-iodine diet, even less is required.

Avoid the following seafood and seafood additives:

  • Fish 
  • Seaweed 
  • Prawns 
  • Crabs 
  • Lobster 
  • Sushi 
  • Carrageen 
  • Agar-agar 
  • Algae 
  • Alginate 
  • Nori 
  • Kelp 

Avoid additional iodine-rich meals like:

  • Milk
  • Cheese
  • Egg yolks 
  • Ionised water with salt
  • Certain food colours


It is one of many foods that can worsen thyroid disease symptoms. Alcohol can affect the body’s ability to produce thyroid hormone and possibly raise the likelihood of an autoimmune disease. It is crucial to refrain from drinking if you have thyroid problems.

Refined Sugar

Sugar comes in a wide variety, but refined sugar is the worst for your thyroid. Processed foods like candy, cookies, and cake contain refined sugar. Some yoghurt flavours and breakfast cereals also have them. Your blood sugar levels increase when you consume refined sugar.

As a result, your body releases insulin, which might result in weight gain and other issues. Your pancreas and liver can also be harmed by eating too much-refined sugar.

Please avoid Refined sugar if you have a thyroid issue. It covers the majority of sweets, sweetened beverages, and packaged snacks. Instead, concentrate on eating healthy foods like fruits, vegetables, and lean protein.


Lemon balm and bugleweed are the main herbs that interact with thyroid hormones and pharmaceuticals. Additionally, it might stop the production of thyroid hormones. It thus causes the metabolism to slow down even more. Therefore, one should avoid these herbs to maintain a healthy thyroid.

Manage Your Thyroid like a Pro

To improve health holistically, more consistently, and experience change unlike anything else, it is crucial for everyone to know what they should eat and what to avoid due to the rise in thyroid patients. For this reason, you must talk to a nutritionist.

The HealthifyMe Note

Combining medical treatment with a healthy diet and lifestyle modification is the best way to maintain an average thyroid level. Usually, the impact of a thyroid irregularity results in unhealthy weight gain or loss. Therefore, even if you do not experience any discomfort, always address weight fluctuations. In addition, in a high-stress environment, we have irregular food schedules, wrong sleep hours and poor activity levels. However, sometimes returning to healthy eating, moving more, and sleeping adequately can help you reverse several common lifestyle diseases. 


It is important to note that although thyroid illness is a significant health concern, it is also possible to stop it from developing in the first place. Modifying one’s food and way of life can help reduce the likelihood of additional difficulties by acting as a preventive intervention.

Limit your consumption of soy products. Avoid processed foods that have sugar or preservatives added. Instead, increase your intake of fresh produce, lean protein, and healthy fats. To feel better despite the condition, eat wisely.
