5 Foods To Avoid With Hashimoto’s Disease


If you’re living with Hashimoto’s — an autoimmune disease that involves the body essentially attacking the thyroid — then you know how important it is to make choices that help you feel good every day. Trying to deal with symptoms such as weight gain, chronic fatigue, muscle weakness, joint pain, and more, can feel overwhelming and, on some days, defeating. So, it’s crucial to be aware of your daily behaviors, including what you’re choosing to eat. Some foods can aggravate symptoms and cause more thyroid problems, while other foods can be an important healing component of your Hashimoto’s diet plan. 

The 5 foods listed below should raise a red flag to anyone with Hashimoto’s. Here’s why you should avoid or limit your consumption of them as part of your Hashimoto’s diet.

1. Cruciferous Vegetables – Avoid Them Raw

If you have Hashimoto’s, think twice about eating these raw. This group of vegetables, including cabbage, broccoli and cauliflower, contain glucosinolates (substances known as goitrogens that disrupt the production of thyroid hormones). More specifically, these glucosinolates are blocking iodine, which is essential in making those hormones. Small amounts of raw goitrogenic veggies have not been found to aggravate the autoimmune thyroid, so don’t eat them raw. However,  and eating these cruciferous vegetables cooked is a much safer option. 

2. Canola Oil – Avoid Completely 

Speaking of goitrogens, canola oil is another that should be avoided. Although it’s considered a good alternative oil for cooking at high heat, it’s also highly processed and refined. Try avocado oil or coconut oil and beware of processed foods that may contain canola oil, like salad dressings, mayonnaise, margarine and others. Read the labels and specifically the ingredients label!

3. Soy- Avoid Completely 

Yet another goitrogen that can be detrimental to Hashimoto’s patients. Unlike with cruciferous vegetables where cooking them eliminates the concern, soy contains the goitrogens even after cooking. For some, consuming soy can cause a thyroid crash, leaving you feeling drained and exhausted the day after eating it.

4. Avoid Excessive Amounts of Omega 6 Foods

Our bodies require both omega-3 (reduce inflammation) and omega-6 (promote inflammation) fats, but it’s important to strike a balance and most of us are consuming way too many omega-6 fats. This can be problematic for most people, but even worse for those with Hashimoto’s, who already have some level of inflammation. Vegetable oils, for example, have a high content of omega-6 fats. Opt for olive and sunflower oils, or flaxseed oil, known for its omega-3 content. For those who enjoy meat, organic, grass-fed beef has fewer omega 6 fats than corn-fed beef.

5. Gluten – Remove as Much as Possible  

Gluten increases intestinal permeability, which can lead to what is called “leaky gut.” If you have Hashimoto’s, you more than likely have some degree of gluten intolerance. Removing gluten from your diet helps reduce inflammation and increases the absorption of many nutrients. If you have leaky gut already, explore repairing it with the addition of collagen peptides into your diet, as collagen can help repair your intestinal lining

To Help Heal, Eat More Probiotics … and Collagen 

They are a great natural way to increase or rebalance gut flora (the good bacteria) – increasing the probiotics in your diet, and repairing your intestinal lining – increasing collagen in your diet.  When choosing foods such as yogurt with probiotics be sure to consume a natural kind, one without too much or any sugar (many yogurt brands include 4 ½ teaspoons of sugar per 6-ounce container!). Eating fermented foods such as sauerkraut, kimchee, and other pickled veggies can als offer gut-balancing benefits. Eating more foods with collagen in it such as bone broth, fish skin, chicken skin or taking daily collagen peptides can also help improve your gut health.

    Hi Mary ,
    The night shade family includes peppers, tomatoes, eggplants and potatoes.
    Some people may have a reaction to them and others have none . You need to eliminate them and reintroduce them one at a time to see if you are reacting to a specific one or all of them .

  2. Mary

    Jackie, Try not to get overwhelmed with the diet restrictions. Try eliminating gluten or dairy first and then move on to dairy. When doing an elimination diet – you need to give it a minimum of 3 weeks so be patient. Breakfast could be GF oats or GF toast with mashed avocado or almond butter. I have Hashimoto’s and eat eggs and they don’t bother me, but it can be individualized. Its a good idea to eliminate one thing at a time to see if there are any changes in the way you feel. As for the vegetables – the cruciferous vegetables which contain goitrogens should be cooked but you can still eat them. You still have a large number of choices. Good luck .

    Cheryl, Food can make a big difference in many health issues. Many patients with Hashimoto’s may have issues with absorption with may be contributing to your tinnitus. Cleaning up your diet and creating a healthy gut will help improve any of the symptoms of Hashimoto’s. Good luck

    I have had Hashimotos for a long time. Never knew I was making it worse with my diet. I have tinnitus and vertigo.

  5. Jackie

    I just found out that I have Hashimotos. After reading about diets,I am told to stay away from dairy,gluten,some vegetables,no eggs,no nuts and seeds. With all these restrictions,what am I supposed to eat,esp. for breakfast?? This is so depressing and overwelming.

    ssicated meds –what happens if my boby rejects them—now having hashimotos sysyems—????–what can be done –under dr.care–but he is surprised at the rejection

    I’m finding conflicting information on eating potatoes. Please help. Like baked potatoes? Or just better to do sweet potato? However I’d like to know if need to avoid 100% like when in a restaurant…

      Thanks for the question-many of our collagen customers have autoimmune diseases like hashimotos. However we recommend you follow up with your medical care practitioner with any further questions.

    Thank you for the info about Hashimoto’s Thyroiditis. My family Dr. Nor my endocrinologist DIDN’T even bring it up. When I brought it up I was treated like a hypochondriac. What wrong with seeing a rheumatoidologist to check it out. I mean taking synthroid hasn’t helped at all. My Dr.s and family think I’m crazy but what is so wrong with changing my diet to try to feel better. Singed,
    Frustrated as hell

    Gluten intolerance
    Corn intolerance
    Nightshade vegetable intolerance
    Whole grain intolerance
    Severe eczema
    Appreciate your info greatly!

    Hey Crystal,
    Yes, sauerkraut is fermented but that process breaks down the goitrogens. You can eat the sauerkraut but not the raw cabbage.

  11. Crystal

    Cabbage is a cruciferous vegetable, which is to be avoided. However, the article recommends “Eating fermented foods such as sauerkraut…” which is cabbage.

  12. Nancy

    Hi I have very high levels of tpo antibodies and thyroid levels.. is consuming overnight soaked almonds everyday is harmful ?

  13. Kristine

    I have heard some people say to go completely grain free, others gluten free, and some say sprouted flour or ancient grains are okay. What is you take on it?

  14. Trish Melton

    My Dr said the foods not to eat are.. Dairy Sugary Flour. This works I feel better an the weight melts away..

    Hi Tiana,
    Eating chicken that is soy free, grass fed and organic is the best choice when eating chicken or meat of any kind. Remember, we eat what the chicken ate. As a Hash patient avoiding soy is a good idea.
    Good luck and keep up with eating “clean”.

    Hope this helps, Mary

  16. Tiana Phillips

    What is your opinion on eating chicken that has been fed some soy and corn, organic or not? My NP is supporting me dealing with my hashis thyroiditis with diet and a thyroid support supplement.
    I am being very strict with my diet, but eat a lot of chicken, so this is important to me

  17. Mary Opfer

    There is no specific meats to avoid if you have Hashimoto’s. If you eat meat try to eat grass fed organic beef it contains higher amounts of omega 3’s and is less inflammatory. If you choose not to eat meet must be sure to get enough fatty acids in your diet and B vitamins.

  18. Carrie

    Thank you so much for sharing this article. I learned a ton of good information recently diagnosed with Hashimoto hypothyroidism and not knowing much about this disease this article has helped clear up some confusion and gave me some great ideas on what to do and what to avoid.

  19. Bren

    This is so helpful, so pleased to have come across your article. I’ve had Hashimoto for 10 years and some weeks are really brutal with the extra fatigue you carry, even with drinking your meds. So glad to learn the types of foods you really do need to avoid. Any extra tips you can throw my way would be greatly appreciated, God Bless you! I hate Hashimoto:( It really sucks and unless you are experiencing this you won’t be able to understand it.

    Thank you so much for this article on what to eat and what to avoid with a Hashimotos Desease.. The guidelines have cleared up doubts regarding my diet. God bless you abundantly.

    I have had hoshimotos disease for about 10 year’s. I had to initially threaten my doctor to get him to get more testing done. I was told I was crazy basically. Finally the threat of an attorney, that’s how sick I was, the testing began. I was diagnosed right away. I have since been also diagnosed with RA and fibromialga. I was pleased to find your article. I knew of a few of the items I needed to stay away from, but way I’m glad to get the total list. Thanks. It’s been a struggled with work, weight, and just life. But it beats the alternative.

  23. Toni

    I’m drinking Collagen+C pomegranate, 4,000 mg liquid and Amino Sculpt antisging type 1, Collagen Petides, are this good.

    “Small amounts of raw goitrogenic veggies have not been found to aggravate the autoimmune thyroid, so don’t eat them raw.” This statement is confusing to me: Are you saying that EVEN small amts are aggravating so don’t eat them raw or are you saying that small amts are okay?

  25. Lisa

    Very helpful! Thanks! I knew about the raw cruciferous but not about the soy or canola. I was a serious vegan for 17 years and finally went back to eating fish and chicken because i became so highly allergic to soy. I still had these stomach-abdominal cramps that would go on for 2-3 days! I went gluten-free and that helped but didn’t totally fix it. Through elimination it turned out to be chicken egg allergy. I now eat organic duck eggs/non GM0/No soy feed. Only get stomach cramps now when it’s really hot. A couple of magnesium citrate and I’m good to go. Yes, and all symptoms confirmed by various testing. IgG, IgE, etc.
