The foods you eat canâ€™t cure you of Gravesâ€™ disease, but they can provide antioxidants and nutrients that may help alleviate symptoms or reduce flares.
Gravesâ€™ disease causes the thyroid gland to produce too much thyroid hormone, which can result in hyperthyroidism. Certain symptoms associated with hyperthyroidism include:
- extreme weight loss, despite eating normally
- brittle bones and osteoporosis
Diet plays a big factor in managing Gravesâ€™ disease. Some foods may exacerbate Gravesâ€™ disease symptoms. Food sensitivities or allergies may negatively impact the immune system, causing disease flares in some people. For this reason, itâ€™s important to try to identify the foods you might be allergic to. Avoiding these foods may lessen symptoms.
Foods to avoid
Talk to your doctor or to a dietitian to help determine which foods you should avoid. You might also keep a food diary to track which foods aggravate your symptoms and which foods donâ€™t. Some types of food to consider eliminating include:
There is a higher incidence of Celiac disease in people who have thyroid disease than there is in the general population. This may be due, in part, to a genetic link. Foods containing gluten may make treatment more difficult for people with autoimmune thyroid diseases, including Gravesâ€™ disease. Many foods and drinks contain gluten. Itâ€™s important to read labels and to look for gluten-containing ingredients. These include:
- wheat and wheat products rye
- barley malt
- brewerâ€™s yeast
- grains of all kinds such as spelt, kamut, farro, and durum
There is some evidence that excessive iodine intake might trigger hyperthyroidism in older adults or people who have a preexisting thyroid disease. Iodine is a micronutrient that is necessary for good health, so taking in the right amount is important. Discuss how much iodine you need with your doctor.
Iodine-fortified foods include:
- dairy products, such as milk, cheese, and yogurt
Foods which are naturally high in iodine include:
- seafood, especially white fish, such as haddock, and cod
- seaweed, and other sea vegetables, such as kelp
Avoiding meat and other animal products
One study found evidence that vegetarians had lower rates of hyperthyroidism than those who followed a non-vegetarian diet. The study found the greatest benefit in people who avoided all animal products, including meat, chicken, pork, and fish.
Foods to eat
Foods containing specific nutrients can help reduce some of the symptoms associated with Gravesâ€™ disease. These include:
Hyperthyroidism can make it difficult for your body to absorb calcium. This can cause brittle bones and osteoporosis. Eating a diet high in calcium may help, although some dairy products are fortified with iodine and may not be as beneficial for you as others.
Since you need some iodine in your diet, itâ€™s important to talk to your doctor or dietitian about which dairy products you should eat, and which you should avoid. Other types of food that contain calcium include:
- almonds kale
- sardines okra
Foods high in vitamin D
Vitamin D helps your body absorb calcium from food more readily. Most vitamin D is made in the skin through the absorption of sunlight. Dietary sources include:
- cod liver oil
- salmon tuna
Foods high in magnesium
If your body doesnâ€™t have enough magnesium, it can affect its ability to absorb calcium. A magnesium deficiency may also worsen symptoms associated with Gravesâ€™ disease. Foods high in this mineral include:
- dark chocolate
- brazil nuts
- pumpkin seeds
Foods containing selenium
A deficiency in selenium is associated with thyroid eye disease in people with Gravesâ€™ disease. This can cause bulging eyeballs and double vision. Selenium is an antioxidant and a mineral. It can be found in:
- brown rice
- brazil nuts
- sunflower seeds
Gravesâ€™ disease is a leading cause of hyperthyroidism. While it cannot be cured through diet, its symptoms can be reduced or alleviated in some people. Learning if you have any food sensitivities or allergies will help you determine what you should and shouldnâ€™t eat.
There are also specific nutrients your body needs to reduce disease flares and symptoms. Talking to your doctor or a dietitian and keeping a food diary can help you determine what to eat and what to avoid.
