    Graves’ disease is an autoimmune disorder that is directly linked to the thyroid. Common symptoms of Graves’ include fatigue, weight gain, and goiter. One method of treatment for Graves’ disease is radioactive iodine therapy (RAI). RAI has been proven effective in controlling the hyperthyroidism symptoms associated with Graves’ as well as reducing the size of a goiter or nodules in the thyroid. After undergoing RAI therapy, it is important to maintain a diet that is tailored towards supplementing this medical treatment.

    A few dietary tips for people who have had RAI treatment for Graves’ disease include:

    • Avoiding large amounts of iodine-containing foods (such as seafood and seaweeds).
    • Eating foods high in selenium and zinc to help counteract radiation.
    • Avoiding processed food made with hydrogenated oils.
    • Eating plenty of omega-3 fatty acids from fish, flaxseed oil or nuts and seeds.
    • Incorporating antioxidant-rich fruits and vegetables into your diet (such as blueberries and broccoli).
    • Replacing refined carbohydrates with whole grains like oats and quinoa.
    • Drinking plenty of water throughout the day to remain well hydrated.
    • Avoiding taking dietary supplements containing iron or calcium at least 4 hours before or after taking any medication used to treat Graves’ hypothyroidism.

    Following these dietary guidelines can help ensure that you are receiving all the nutrients necessary for optimal health after RAI therapy for Graves’ disease.

    What is Graves Disease?

    Graves’ Disease is an autoimmune disorder that causes the thyroid gland to produce too much of the hormones thyroxine (T4) and triiodothyronine (T3). These hormones regulate a variety of bodily functions, such as metabolism, growth, and energy. The disease is typically treated with radioactive iodine therapy. While this treatment can be effective in controlling symptoms, it can also negatively affect other bodily functions, including appetite and nutrition. It is important to follow a balanced diet post-treatment in order to help manage the disease and its symptoms.

    A balanced diet for Graves’ Disease should include:

    • Plenty of calcium-rich foods such as dairy products and dark green vegetables.
    • Protein sources such as lean meats, beans, nuts, and legumes.
    • Whole grains, fruits and vegetables.

    When shopping for pre-packaged foods it is important to look at the nutrition labels carefully; sodium levels should be kept low and processed sugars should be avoided altogether. Foods with added sugar or sweeteners should also be avoided because they can cause blood sugar spikes that can lead to fatigue or weakness later on in the day.

    Radioactive Iodine Treatment

    Radioactive iodine treatment is the most common form of treatment for Graves’ disease. This type of treatment uses a form of iodine isotope (radioactive iodine) to target and destroy the cells in the thyroid gland that are overproducing thyroid hormones. After undergoing this type of treatment, it is important for patients to adhere to a healthy diet in order to promote recovery and maintain optimal health.

    The best diet for Graves’ disease after radioactive iodine treatment should include:

    • Plenty of nutrient-dense foods, such as fruits and vegetables, lean proteins, whole grains, low-fat dairy products, beans and legumes, healthy fats like olive oil and almonds, and limited amounts of processed sugars.
    • Avoiding foods with added sugar or unhealthy saturated fats like red meat or butter.
    • Drinking plenty of water throughout the day to flush out toxins from the body more quickly.

    Diet Considerations

    Following a healthy diet is an important part of managing Graves’ Disease, especially after undergoing radioactive iodine treatment. Eating a variety of nutritious foods can help support the immune system, reduce inflammation, and provide essential nutrients for recovery.

    Let’s explore what dietary considerations should be kept in mind for those with Graves’ Disease:

    Avoid processed and refined foods

    Graves’ disease is an autoimmune thyroid disease that affects the body’s metabolism. After receiving Radioactive Iodine Treatment (RIT), it is important to follow a suitable diet in order to maintain health and well-being.

    To achieve this, it is important to avoid processed and refined foods, such as pre-packaged snacks and treats, white bread, pasta and sugar. Eating these types of food can cause hormone imbalances which can exacerbate Graves’ disease symptoms.

    Eating a diet rich in whole foods such as fruits, vegetables, lean proteins and healthy fats while avoiding processed foods can help keep hormones balanced. Additionally, limiting the amount of caffeine and alcohol consumption can also help reduce symptoms associated with Graves’ disease after RIT treatment.

    Increase intake of plant-based foods

    For those affected by Graves disease who have undergone radioactive iodine treatment, the best diet to follow is one that focuses on plant-based foods. Plant-based foods include fruits, vegetables, beans, nuts, and grains. These types of foods are packed with essential vitamins and minerals that are important for a healthy body. Additionally, plant-based diets can help control weight as well as reduce levels of inflammation in the body. Eating plant-based foods also reduces your risk of chronic conditions such as heart disease and diabetes.

    It’s important to note that eating a plant-based diet doesn’t mean cutting out all animal products; it just means that the majority of your daily meals should focus on unprocessed fruits and vegetables, legumes, whole grains, nuts and seeds.

    Increase intake of antioxidant-rich foods

    People with Graves Disease should increase their intake of antioxidant-rich foods after radioactive iodine treatments. Studies show that antioxidants can help protect the body from some of the potentially harmful effects of radiation exposure. Foods high in antioxidant content include fruits and vegetables, nuts, and whole grains, as well as foods that have been fortified with vitamins E and C, selenium, and other essential minerals and vitamins.

    Furthermore, adding turmeric to your meals is beneficial as turmeric is known to reduce inflammation while helping the body detoxify from radiation therapy.

    In addition to consuming antioxidant-rich food sources, it’s important to reduce your sodium intake as increased sodium levels can trigger symptoms for those treating Graves Disease with radioactive iodine treatment. Reducing sodium helps reduce fluid balance issues in the body so that tissues are not overworked or overwhelmed when exposed to radiation.

    Finally, avoiding processed foods is also recommended due to the unknown ingredients in many processed products that may counteract any beneficial effects of the antioxidants in a healthy diet.

    Increase intake of omega-3 fatty acids

    Graves’ disease is an autoimmune disorder that affects the thyroid gland, and is typically treated with radioactive iodine. People with Graves’ disease can improve their symptoms by following a healthy diet to promote better balance of hormones.

    The consumption of omega-3 fatty acids has been shown to reduce inflammation, especially in autoimmune diseases like Graves’. Increasing your intake of omega-3 fatty acids can help to lower your levels of TPO (thyroid peroxidase) antibodies and other markers associated with Graves’ disease activity.

    Omega-3s are found in a variety of sources such as:

    • Chia seeds
    • Flaxseeds
    • Walnuts
    • Fish, salmon, sardines and mackerel

    Incorporating those foods into your diet will provide you with an abundance of the beneficial fatty acids known to reduce inflammation in the body.

    Increase intake of probiotics

    Incorporating probiotics into the diet after radioactive iodine treatment for Graves’ disease may help to improve gut health and reduce inflammation. Probiotics are beneficial bacteria that are found in fermented food sources such as yogurt, kefir, kraut, and kimchi. Probiotics are known to help improve digestion and immunity, as well as decrease inflammation by suppressing overactive immune cells.

    Certain strain of probiotic bacteria like Lactobacillus or Bifidobacterium may further work to reduce inflammation by decreasing the activation of immune cells that can cause Graves’ disease symptoms. In addition, consuming adequate amounts of prebiotic-rich foods is also important to keep a healthy balance of gut bacteria. Prebiotics are plant fibers that cannot be digested by humans but can be digested by beneficial gut bacteria, providing them with energy for growth and replenishment.

    Good prebiotic sources include:

    • Onions
    • Garlic
    • Asparagus
    • Artichokes


    Taking supplements on a daily basis can help to improve recovery time and overall health after undergoing radioactive iodine treatment for Graves’ disease. Supplementation can also help to reduce inflammation and aid in digestion.

    There are various types of supplements that can be beneficial for people with Graves’ disease, including vitamins, minerals, antioxidants, and probiotics. In this article, we will discuss the best diet for Graves’ disease after radioactive iodine treatment and the most suitable supplements to take.

    Vitamin B12

    Vitamin B12 is a water-soluble vitamin that plays an important role in the body’s metabolism and cell production. It is found naturally in certain foods such as fish, meat, dairy products, and eggs.

    For individuals with Graves’ disease who have received radioactive iodine treatment, vitamin B12 should be supplemented to help combat fatigue, mood swings, and depression. Vitamin B12 has also been shown to reduce inflammation which is beneficial for those with Graves’ disease.

    In addition to supplementing with B12, it’s also important to consume enough of it from food sources. Thus, incorporating foods like:

    • Fish (tuna/salmon)
    • Meat (chicken/lamb)
    • Dairy products (low-fat milk/yogurt)
    • Eggs (both raw and cooked)

    into your diet will ensure you can get adequate levels of Vitamin B12 on a daily basis.


    Selenium is a trace mineral found in many foods, including nuts, fish, shellfish and beans. It helps the body protect cells from damage and promotes a healthy immune system.

    After receiving Radioactive iodine treatment for Graves Disease, the body’s absorption of iodine is reduced, resulting in lower levels of iodine in the body. Since selenium needs to bind to iodine in order for it to be absorbed properly by the thyroid gland, taking Selenium supplements can help maintain its levels.

    Selenium also helps to decrease inflammation associated with Graves Disease as well as aid in reducing oxidative stress. For people struggling with elevated inflammation markers due to Graves disease , Selenium can help maximise their results and reduce their symptoms even further.

    In addition to taking selenium supplements health professionals also suggest eating foods that are high in this trace mineral such as brazil nuts, sunflower seeds and canned tuna.

    Vitamin D

    Vitamin D is an important vitamin that helps to regulate the functioning of the thyroid gland. It helps the body absorb calcium and phosphorus, two vital elements for healthy bones and teeth. After radioactive iodine treatment, it is important to replenish levels of vitamin D in your body as it can help support the immune system and prevent further damage to the thyroid gland.

    Vitamin D3 is more effectively absorbed by the body than Vitamin D2 and should be taken on a regular basis after undergoing radioactive iodine treatment. It should be noted however, that too much Vitamin D can lead to increased risk of bone fractures and muscle weakness, so it is important to monitor levels when taking supplements. Additionally, taking a multivitamin with other essential vitamins and minerals can help support your health during this time.


    Iodine is an important mineral for the human body, especially for people suffering from Graves’ disease. After undergoing Radioactive Iodine treatment, the thyroid gland is unable to produce enough iodine to sustain normal body functions. Therefore, it is essential for these individuals to supplement with iodine in order to lower levels of antibodies as well as restore hormonal balance.

    Iodine supplements can come in multiple forms – from liquid drops and powder to tablets. The most common type of iodine supplement is potassium iodide, an organic compound that helps supply the body with the missing element. Low-dose (up to 200mcg) or moderate-dose (up to 500mcg) of iodine can often be found over-the-counter. However, if a person needs a higher dose after consulting their doctor, prescription products are also available.


    When it comes to managing Grave’s Disease after Radioactive Iodine Treatment, diet plays an important role. It is important to choose nutritious and healthy food that will provide a steady and sustained energy source. Avoiding processed foods, sugars and high glycemics carbohydrates is a must. Eating smaller more frequent meals throughout the day and drinking plenty of water will help keep blood sugar levels in check.

    Adding Omega-3 fatty acids, fiber-rich foods, antioxidants, magnesium-rich foods, iron-rich foods and probiotics to your diet can also help improve symptoms of Graves’ Disease.

    Overall, the best diet for Grave’s Disease after Radioactive Iodine Treatment is one that emphasizes:

    • Whole grains
    • Vegetables
    • Fruits
    • Low-fat dairy products
    • Lean proteins

    This approach can help provide essential nutrients while avoiding unhealthy ingredients that can exacerbate the disease’s symptoms.
