Diet Hashimoto's Thyroiditis


Our thyroid is heavily affected by what we eat . Poor nutrition and an unregulated diet not only hinder the proper functioning of the thyroid but can also interfere with the medications recommended by your endocrinologist.

It often happens to receive patients who, despite having perfect exams, feel "grounded". They are not dreaming of it, far from it.

Discover the nutritional plan
specifically for Hashimoto's thyroiditis






Studies have shown that a deficiency in selenium, potassium, iodine, copper, magnesium, zinc, iron, vitamins A, B, C and D can lead to the development of Hashimoto's thyroiditis (1).

Obviously, in most cases there is a genetic predisposition that can be evaluated with  genetic testing  targeted. 

Sara as a specialized nutritionist biologist can advise you where to take these genetic tests in Novara and above all if they are necessary to develop even more targeted nutritional plans.

Furthermore, a dysbiosis of the gut microbiota can have negative effects on thyroid function 


Initially, Hashimoto's thyroiditis is silent or at most has a slight swelling in the part of the throat, where the thyroid is located.


This disease progresses slowly over the years and causes chronic thyroid damage leading to a drop in thyroid hormone levels. The symptoms are the same as for hypothyroidism: 

  • Fatigue and tiredness

  • Increased sensitivity to cold 

  • Constipation

  • Pale and dry skin

  • Swollen face

  • Brittle nails

  • Consistent hair loss

  • Unexplained weight gain 

  • Muscle aches and weakness

  • Prolonged or excessive menstruation

  • Depression or sadness

  • Memory lapses

Thyroid and nutrition go hand in hand. A diet for Hashimoto's thyroiditis can be tailored for you by Dr. D'Imperio in her office in Novara or through her online service.

Some clinical trials have shown that the following diets have helped some people with Hashimoto:

  • Gluten free diet

  • Sugar free diet

  • Paleo diet

  • Grain-free diet

  • Dairy-free diet

  • Low glycemic index diet

While there is not yet a specific diet to treat all patients with Hashimoto's thyroiditis, it has been shown that diet and lifestyle play a fundamental role in improving quality of life and health.


Unfortunately, hormonal treatment is not enough to counteract the classic symptom of fatigue, for example. An individualized nutritional approach is therefore required.


 Lifestyle and dietary changes can help reduce inflammation, slow or prevent thyroid damage, and manage body weight, blood sugar, and cholesterol levels. 


In fact, also due to this reason, many people who have symptoms are not given drugs unless they have altered hormone levels. Additionally, research suggests that inflammation may be a driving factor behind Hashimoto's wide range of symptoms. Inflammation is often related to diet.

Hashimoto's thyroiditis and celiac disease

Recent medical research has shown that there is a connection between forms of thyroiditis and celiac disease . Celiac disease has several symptoms in common, most notably with autoimmune thyroiditis.

In fact, it is very important to go to a specialist in order not to misdiagnose thyroiditis or celiac disease by mistake. The most frequent common symptoms are: constipation, diarrhea, cramps, bloating, nausea, reflux, gas, headache, fatigue. 
Gluten-free diets remove all foods that contain gluten, which is a protein found in wheat, barley, rye, and other grains.
Gluten is commonly found in pasta, bread, baked goods, beer, soups, and cereals. The best way to go gluten-free is to focus on foods that are naturally gluten-free, such as vegetables, fruits, lean meats, seafood, beans, legumes, nuts, and eggs.

Hashimoto's thyroiditis and other diseases

People with Hashimoto's disease have an increased risk of developing autoimmune conditions, high cholesterol, obesity, and diabetes.
While there are no particular foods or supplements that are helpful for thyroid disease, a balanced meal plan can improve the health of people with thyroiditis.
Essential nutrients such as selenium, zinc and iron are critical for thyroid function.
For example selenium and zinc are required for the conversion of the hormone T4 (thyroxine) into T3 (triiodothyronine). Iron deficiency has also been linked to hypothyroidism, particularly Hashimoto's disease.
When iodine is lacking, the thyroid cannot produce sufficient levels of thyroid hormones , so iodine-rich foods are essential to ensure healthy hormone production.
Calcium, essential for our existence, can however interfere with the absorption of levothyroxine. So, if you are deficient in calcium, take it at least 4 hours after taking thyroid replacement hormone. Beware that if you are trying to lose weight and use low-fat (i.e. semi-skim or skimmed) milk, it remains high in calcium despite being lower in fat.
Another food that a person with hypothyroidism (including Hashimoto's) needs to look out for is soy. It interferes with the absorption of levothyroxine, decreasing its function. However, if you can't do it to me and you want to take soy, you should allow as much time as possible between taking hormone therapy and taking the soy food. 


If you have thyroid disease, a healthy diet, exercise and stress reduction are important lifestyle factors for optimizing health and well-being.
In addition to being important to keep muscle mass active by exercising regularly and consuming a balanced diet with proteins​​ distributed throughout the day, it is also essential to know how to manage stress and get enough sleep.
Stress is one of the interferences that is created between  thyroid gland and brain. A prolonged state of stress can have a more significant physical manifestation for those suffering from thyroid disease.
It is also important to eat a varied diet to ensure that we are consuming a range of nutrients, and to be careful about taking in substances that can further compromise our health.

Hashimoto's thyroiditis supplements can be a valuable resource for improving thyroid function and overall well-being.

Iodine Supplements:

Iodine is essential for thyroid hormone production. However, iodine intake must be carefully dosed, as excess can worsen symptoms. High-quality iodine supplements, when used moderately and under a health professional's supervision, can benefit those suffering from Hashimoto's thyroiditis.

Selenium: Selenium is a mineral that can play an important role in reducing inflammation associated with Hashimoto's thyroiditis. Studies have shown that selenium intake can help improve thyroid function and reduce anti-thyroid antibody levels.

Vitamin D: Vitamin D is crucial for immune health and can help regulate the autoimmune response in Hashimoto's thyroiditis. Vitamin D supplements can be useful, especially in cases of deficiency.

Omega-3: Omega-3 fatty acids, often found in fish oils, have anti-inflammatory properties that can help reduce inflammation associated with Hashimoto's thyroiditis.

Adaptogens: Adaptogenic herbs like ashwagandha and ginseng can help manage stress and improve thyroid function. These natural supplements can be useful for stabilizing hormones and enhancing energy.

It's important to emphasize that before starting any new supplement regimen, it's essential to consult a doctor or endocrinologist specialized in managing Hashimoto's thyroiditis, along with a nutritionist specialized in this condition. Each individual is unique, and what works for one person might not work for another. Additionally, a balanced diet and healthy lifestyle are also essential for managing Hashimoto's thyroiditis.

In conclusion, supplements for Hashimoto's thyroiditis can be a valuable resource in managing the condition, but they should be used wisely and under the supervision of a healthcare professional. When combined with a balanced diet and healthy lifestyle, they can contribute to overall well-being and thyroid health.
