Both hypothyroidism and hyperthyroidism are conditions that share a common origin: the thyroid gland.
Today I’ll talk about hypothyroidism, also known as underactive thyroid, and what you should keep in mind regarding your diet.
The most common cause of hypothyroidism is an alteration in the immune system, known as Hashimoto’s hypothyroidism. Other causes include:
- Iodine deficiency in the diet
- Radiation therapy treatments
- Removal of the thyroid gland
- Thyroid nodules
- Ingestion of certain medications
- Development of a viral infection
A disorder occurs in the glands in the brain responsible for stimulating the thyroid (pituitary gland or hypothalamus). This type is called secondary hypothyroidism.

More About Hashimoto’s Disease
The thyroid gland needs iodine to produce the hormones T3 and T4. This mineral must be obtained through the foods in our diet.
A healthy adult needs to ingest about 200 mcg of iodine per day. According to the WHO (World Health Organization), 40% of the world’s population is at risk of having an iodine deficiency. The Galician Society of Endocrinology, Nutrition, and Metabolism has studied the areas of Spain with the greatest iodine deficiency: Andalusia, Asturias, Catalonia, Extremadura, Galicia, and Castile.
Iodine is a mineral found in the soil, and therefore, depending on the iodine content of the farmland, the vegetables consumed will have a greater or lesser amount of this mineral. Another important source of iodine is the sea, so we recommend consuming seafood such as fish and shellfish.
It is advisable to be cautious with seaweed consumption, as its iodine content is so high that it could disrupt the thyroid gland. Currently, two important strategies are implemented to prevent iodine deficiency in the diet.
The most important is the iodization of table salt (not to be confused with sea salt, which loses iodine during processing). The other is feeding iodine‑enriched feed to dairy cows, making dairy products a good source of this mineral.
In addition to iodine, other nutrients are important for ensuring proper T4 production and its conversion to T3. These include:
- Zinc: present in red meat, shellfish, wheat germ, and nuts.
- Iron: present in all meats and fish in its most bioavailable form.
- Manganese: abundant in nuts, seeds, and whole grains.
- Vitamin A: in the form of beta‑carotene, found in green vegetables (chard, spinach, broccoli, etc.) and orange vegetables (carrots, pumpkin, sweet potato, etc.).
Conclusion
Once the disease is diagnosed through a blood test that measures hormone levels, in addition to the prescribed medication, following a diet designed by a registered dietitian nutritionist can be very helpful.
