25 Foods and Nutrients for Healthy Thyroid Function


The thyroid is one of the most important endocrine glands in the human body. It produces three hormones that are absolutely essential for the proper functioning of the body. These hormones are:

Triiodothyronine (T3), thyroxine (T4) and calcitonin.

Thyroid hormones (T3, T4) contribute to the regulation of glucose, fat and cholesterol metabolism, the regulation of body temperature, intestinal motility, the regulation of heart rate and the speed of muscle contraction. In infancy and childhood, thyroid hormones are also essential for the smooth physical and mental maturation of the child.

Calcitonin, along with parathyroid hormone, is responsible for regulating calcium levels in the blood and bones.


Thyroid disorders

Thyroid disorders are six times more common in women than in men. The most common thyroid disorders are hypothyroidism and hyperthyroidism.

Hypothyroidism is an underactive thyroid gland that leads to a gradual decrease in T3 and T4 in the blood and is manifested by increasing fatigue, physical weakness, lethargy, sensitivity to cold, constipation, weight gain, and dry skin.

Hyperthyroidism is the overactivity of the thyroid gland that leads to an uncontrolled increase in T3 and T4 and manifests itself with increased nervousness, insomnia, tachycardia, easy shortness of breath, intolerance to heat, and increased appetite.


Foods and nutrients for proper thyroid function

We limit (especially if we have hypothyroidism) the following vegetables from our diet because they contain goitrogens that prevent the production and function of thyroid hormones.

1. Cauliflower

2. Cabbage

3. Brussels sprouts

4. Turnip (radish)

5. Mustard

We consume foods with iodine, which is an important component in the production of thyroid hormones, such as:

1. Fish and seafood

2. Dairy products

3. Eggs

4. Plums

5. Salt

We consume foods with selenium, which, in addition to being an essential component in the production of thyroid hormones, has an antioxidant effect, protecting the thyroid gland from free radicals that cause long-term oxidative stress. Selenium is mainly found in the following foods:

1. Meat

2. Fish and oyster

3. Walnuts

4. Brazil nuts

5. Mushrooms


We consume foods with calcium, an essential mineral that is important in many functions, such as bone health, nerve and muscle function and blood clotting. Calcium is mainly found in the following foods:

1. Yogurt

2. Cheese (mainly parmesan)

3. Milk

4. Sardines

5. Salmon

Plant foods rich in calcium:

1. Almonds

2. Spinach

3. Dried figs
