Small in size, but a very important internal human organ is the thyroid gland which plays a major role in human development and improves metabolic rate. It releases thyroxine (T4) and triiodothyronine (T3) which are responsible for most of our body functions. However, uncontrolled production of these two hormones can lead to hyperthyroidism. Weight loss, increased heart rate, anxiety, irritability – these, as well as many other manifestations, are some of the most common indications of hyperthyroidism. That can be controlled with the right diet and some foods to avoid hyperthyroidism. 

The foods we eat play a big role when it comes to keeping the thyroid gland in good shape. In this article, we provided you with a brief about hyperthyroidism and listed hyperthyroid foods to avoid to cure this health condition naturally. So, let’s get started!

What Is Hyperthyroidism?

Hyperthyroidism is a common disease in the thyroid gland that can occur due to excessive production of thyroid hormone. A common cause of hyperthyroidism is caused by increased iodine levels in the body, a substance that the thyroid uses to produce hormones. This causes the body’s cells and organs to work harder, which can cause fatigue, palpitations, and weight loss. Some diseases need medical treatment, while some go away on their own.

Many people think that it is incurable but it’s wrong, hyperthyroidism is a curable disease if we exclude or control the intake of iodine from our diet and take only healthy food. However, during pregnancy there are a lot of hormonal imbalance occurs in the body and it can also be responsible for hyperthyroidism in women.

Eating healthy and avoiding iodine from your diet is one of the best ways to keep the thyroid gland in a good condition. Nutrients such as protein, vitamin A, vitamin D, vitamin C, omega-3, selenium, zinc, and iron are must-haves in your diet to control hyperthyroidism. The last three are crucial for the function of the thyroid gland and help the body to convert active thyroxine (T4) into inactive triiodothyronine (T3). However, those who for some reason suffer from a lack of vitamins or minerals may need to supplement their diet.

What Are The Causes Of Hyperthyroidism?

Many endocrine diseases lead to thyroid dysfunction, such as:

  • Graves’ Disease – The syndrome is autoimmune in nature. The body produces antibodies that stimulate the thyroid gland to produce an excess amount of the T4 hormone.
  • Nodular Goiter, Toxic Adenoma – These pathologies are accompanied by the formation of benign nodes (tumors) in the tissues of the gland. The formations begin to produce hormones and cause hyperthyroidism.
  • Thyroiditis – The inflammatory process destroys thyroid cells. Hormones enter the bloodstream and cause hyperthyroidism. An autoimmune nature of thyroiditis is possible. The body produces antibodies against TSH receptors. The cells cause active growth and inflammation of the thyroid gland.

The disease is most susceptible to people with a hereditary predisposition to endocrine pathologies. Hyperthyroidism is more common in women than in men. The development of the disease is also affected by the environmental situation, excess iodine, and stress which can be recovered with the right food and developing a healthy lifestyle. So, let’s know what to eat and what foods not to eat with hyperthyroidism. 

Best Foods To Eat For Hyperthyroidism

Hyperthyroidism can lead to other critical health conditions such as disturbed menstrual cycles, weight loss, constipation, goiter, depression, dry skin, hair loss, muscle fatigue, slow heart rate, high blood cholesterol, and swollen face. Apart from medicines, you can make a list of thyroid foods to avoid to control function.

Nuts And Dry Fruits

Nuts and dry fruits are a great source of the mineral selenium which helps catalyze the conversion of the inactive thyroid hormone into the active form. Researchers have found that nuts and dry fruits improve thyroid hormone levels. Selenium also reduces inflammation and inhibits cancer cell growth. You can consume a hand full of nuts and dry fruits per day. Do not eat too many as this can lead to nausea, diarrhea, and vomiting.


Fish are rich in omega-3 fatty acids and selenium. Omega-3 fatty acids help lower LDL cholesterol, and selenium keeps thyroid hormone maintained. Consume salmon, sardines, and tuna to counteract hyperthyroidism. 

Vegetables And Fruits

Green leafy vegetables, colorful vegetables, and fruits are good sources of minerals, vitamins, antioxidants, and dietary fiber. However, you should be careful if you suffer from hyperthyroidism, as some vegetables and fruits can inhibit the production of thyroid hormones and are called goitrogens. Plants such as cauliflower, spinach, kale, broccoli, soybeans, cabbage, radish, sweet potato, peach, avocado, and mustard greens are goitrogens. However, cook these vegetables and fruits properly to render the goitrogens inactive.

Beef And Chicken

Your thyroid function can also be controlled by providing your body with the necessary amounts of zinc. It is mainly found in beef and chicken and can help convert triiodothyronine (T3) to thyroxine (T4). This conversion is of great importance because T3 is the active form while T4 is the inactive form of thyroid hormone. Consumption of chicken breast and lean beef help increase thyroxine production in the body


Eggs are a great source of protein that helps increase muscle mass and gain weight, lost by hyperthyroidism. You can safely have two whole eggs per day. Do not consume the egg yolk if you already have elevated cholesterol levels. Otherwise, you can consume whole eggs that are rich in fat-soluble vitamins and other nutrients that are good for your body.

Olive Oil

Start cooking with olive oil if you are not already using it. Olive oil is rich in healthy fats and nutrients that help maintain thyroid hormone levels. Olive oil also helps lower LDL cholesterol, which helps you lose weight and keep your heart healthy. Its anti-inflammatory properties reduce the risk of having hyperthyroidism and its symptoms. 

Flax Seeds

Flaxseeds are a great source of omega-3 fatty acids, zinc, and selenium. It helps you maintain the iodine levels in the body and reduce the risk of hyperthyroidism. You can consume ground flaxseeds with a smoothie or breakfast cereal, or you can use flaxseed oil for cooking. You can safely have 2 – 3 tablespoons of ground flaxseed powder and 2 tablespoons of flaxseed oil per day to cure hyperthyroidism.

Fiber-Rich Foods

Hyperthyroidism can also affect our digestive functions and can cause digestive issues such as indigestion and constipation. So, it is recommended to add fiber rich foods to your diet to improve digestion. Include foods such as papaya, cooked green leafy vegetables, and gluten-free whole grains for better digestion and metabolism.
