While other medical recommendations should be followed, diet plays a very important role in regulating thyroid functions. One of the keys to controlling the symptoms of hypothyroidism is to improve your diet as much as possible. To help you with this, we have compiled the foods prohibited if you have hypothyroidism.
This disease implies a lack of control in hormonal processes that are key to metabolism. For this reason, those who suffer from it tend to gain weight, even while maintaining healthy habits. What are the foods that should be avoided?
A professional should design the nutrition of patients with this problem. However, some foods should generally be moderated to avoid health complications. Discover them!

What is hypothyroidism?
Hypothyroidism, also called underactive thyroid, is a disease of the thyroid gland characterized by low secretion of hormones. By participating in metabolism, cardiovascular health, and other critical vital processes, they trigger adverse reactions due to their imbalance.
The condition is more common among women in their 60s due to hormonal changes. However, anyone can generally suffer from it, even in adolescence. Although it varies according to the region, it is estimated that between 3% and 7% of the world population suffers from it. It does not constantly develop symptoms; when it does, it is classified as subclinical hypothyroidism.
In practice, uncontrolled hypothyroidism can cause various health complications. For example, it is known to cause heart disease, infertility, neurological and musculoskeletal disorders, and poor brain development in children. Although it has many causes, an autoimmune disorder and iodine deficiency account for many cases.
Symptoms of hypothyroidism
No clinical manifestations usually facilitate its detection in the initial stages of hypothyroidism. However, as it progresses unchecked, it can cause:
- Fatigue.
- Dry Skin.
- Weight gain.
- Cold sensitivity.
- Capillary weakening.
- Muscle pain and stiffness.
- Swelling of the extremities.
- Decreased heart rate.
- Increased cholesterol in the blood.
It could also cause trouble concentrating, irritability, and mood disorders (such as depression). In the case of women, irregular menstrual periods.
7 Foods You Should Avoid If You Have Hypothyroidism
Foods that are discouraged for patients with hypothyroidism are called “goitrogens.” They are those that, after assimilating in the body, interfere with the average production of thyroid hormones.
The diet for hypothyroidism is a component of its management and control. Despite this, and as experts warn, most patients do not include changes in their diet after diagnosis.
An anti-inflammatory diet is often recommended to address diagnoses of autoimmune hypothyroidism. Although genetic factors are indeed the protagonists in its development, environmental factors are necessary for destabilizing the immune system. With these reflections, we leave you with seven forbidden foods if you have hypothyroidism.
1. Cereals with gluten
Eating gluten-rich grains can make it challenging to absorb thyroid hormone replacement medications. This is why specialists recommend a gluten-free diet for people with autoimmune thyroid disease.
The immune system perceives gluten as an antigen to be attacked. For this reason, to prevent thyroid complications and, incidentally, promote its proper functioning, it is best to exclude this variety of foods:
- Wheat-based processed products.
- Barley.
- Rye.
- Spelled
- Kamut.
In a study published in the Elsevier journal, the relationship between celiac disease and primary hyperthyroidism was observed, and the symptoms were initially considered a consequence of non-compliance with the gluten-free diet.
2. Broccoli
Broccoli and other varieties of cruciferous vegetables, including cabbages, contain “goitrogens,” which, when absorbed, hinder the absorption of iodine. The latter is an essential nutrient in producing thyroid hormones, so its correct absorption must be guaranteed.
It is known that its moderate intake is safe according to animal models, but the problem arises when consumed regularly or excessively. This happens with other foods prohibited in hypothyroidism, so the recommendation is to moderate your intake.3. Soy
Soy and all its derivatives contain isoflavones, a phytoestrogen that alters the function of the thyroid gland, especially in patients with iodine deficiency. It has been suggested that soy foods may increase the dose of thyroid hormone required by patients with hypothyroidism.
Its consumption must be regulated in any of its presentations:
- Soy milk.
- Tofu.
- Soy sauce.
- Soy protein.
4. Sugar
Patients with hypothyroidism have continuous uncontrolled glucose levels, and insulin resistance can occur when neglected. On the other hand, let’s remember that metabolic function is altered, which can lead to overweight and diabetes.
- The intake of all kinds of foods with sugar should be controlled.
- Its substitution is not recommended, not even with organic sugars, since they can continue to affect blood glucose.
5. Vegetable oils
A wide variety of vegetable oils also carry risks of metabolic problems. Its consumption blocks the function of thyroid hormones and reduces their use by cells.
To avoid those that are counterproductive, it is advised only to use the following:
- Coconut.
- Sunflower.
- Avocado.
- Extra virgin olive.
Regarding the latter, there is evidence that moderate olive oil can affect thyroid control in diagnosed patients .
6. Foods rich in iodine
It is advisable to avoid excessive consumption of foods rich in iodine since they can worsen both hypothyroidism and hyperthyroidism.
Foods richest in iodine are cheese, milk, ice cream, eggs, seaweed, saltwater fish, and iodized table salt.
7. Sausages
Rich in nitrites, nitrates, and other substances, red meat and sausages are the number one enemies of thyroid health. When included too frequently and without moderation in the diet, they can lead to hypothyroidism and, in the face of disease, can cause complications for both metabolism and cardiovascular health.
In this sense, there is evidence that a vegan and vegetarian diet is associated with a lower risk of developing and complicating episodes of hypothyroidism. As we have already warned you, beyond altogether avoiding prohibited foods for hypothyroidism, the ideal is that you appeal for moderation.
Do you suffer from hypothyroidism? Follow the doctor’s advice
Do you have this thyroid problem? Remember that you must improve your lifestyle besides limiting the consumption of these foods we are discussing. Follow your doctor’s instructions, adopt a balanced diet (according to your needs), and avoid a sedentary lifestyle and the consumption of alcohol and tobacco.
