Cause 4: Selenium Deficiency
Selenium is another trace mineral that plays a crucial role in maintaining thyroid health. It contributes to the conversion of thyroxine (T4) into the more active thyroid hormone, triiodothyronine (T3). A deficiency in selenium can therefore impact thyroid function and contribute to iodine deficiency disorders.
While less common than iodine deficiency, selenium deficiency is prevalent in certain regions where the soil has low selenium content. Consequently, crops grown in these soils have low selenium content, which affects the selenium intake of those consuming these crops.
Selenium deficiency can be addressed by consuming selenium-rich foods like Brazil nuts, seafood, and meats. Alternatively, selenium supplements can be used under the guidance of a healthcare professional. (4)
