Why do you say selenium is a key nutrient for thyroid health?

Selenium is a trace element that is critical to human health, especially in maintaining thyroid function. The thyroid is the largest endocrine gland in the human body and is responsible for producing the hormones that regulate metabolize. The following are some of the reasons why selenium is essential for thyroid health:The synthesis of selenium and thyroid hormones.Thyroid hormones, which include mainly thyroidin (T4) and triodine thyroid amino acid (T3), require the involvement of selenium in the synthesis process. Selenium is an integral part of several thyroid enzymes, including iodine peroxide enzymes (TPOs) and deiodine enzymes. These enzymes play a key role in:Iodine activation: TPO is responsible for iodine ion (I-) oxidizing to active iodide (I2), the first step in the synthesis of thyroid hormones.Thyroid hormone coupling: Active Iodine (I2) is then associated with the glycerine glycerine residuals on thyroid protein, forming T4 and T3.Iodine deoding: Deodised enzymes are responsible for converting T4 into a more active T3 and for regulating the metabolism of thyroid hormones.Adequate supplies of selenium are therefore essential for normal synthesis and metabolism of thyroid hormones.Antioxidation protectionThe thyroid is one of the most active metabolic organs in the human body, resulting in a large number of free radicals. Selenium, as a powerful antioxidant, can neutralize these free radicals and protect thyroid cells from oxidation stress. Selenium provides antioxidation protection by:Composed of antioxidation enzymes: Selenium is a key component of the glycerine peroxide enzyme (GPx) family in the valley, which can reduce peroxide in the cell and prevent cell damage.Enhancing the role of vitamin E: Selenium enhances the antioxidation effect of vitamin E, synergies between the two, and increases the resilience of organisms to oxidation.Immunization reconciliationNor is the role of selenium in the immune system negligible, which is essential to maintaining the immunization balance. Thyroid diseases, such as Hashimoto thyroid disease (one of its own immune thyroid diseases), are associated with abnormal reactions in the immune system. Selenium regulates the immune response by:Regulating the functioning of immunocellular cells: Selenium can affect the functioning of T-cells and B-cells and contribute to the maintenance of immunity stability.Reduction of Inflammation: Selenium is resistant to inflammation and can reduce the production of inflammatory media, thereby reducing the risk of its own immune disease.Prevention of thyroid diseasesStudies have shown a correlation between the intake of selenium and the risk of thyroid disease. Here are some thyroid diseases associated with selenium:Thyroid retrenchment: The lack of selenium is associated with increased risk of thyroid retortion, especially when iodine is sufficient.Thyroid swelling: Selenium supplementation has been shown to reduce the incidence of thyroid swelling.Hashimoto thyroid inflammation: extra selenium can improve the symptoms and thyroid function of Hashimoto thyroid in patients.Advice on selenium intakeTo maintain thyroid health, the following are some of the recommendations for selenium intake:A balanced diet: Cereal-rich foods include Brazilian nuts, seafood, meat, whole grains and nuts. Adequate intake of selenium can be ensured through a balanced diet.Replenishment: In some cases, a supplement may be needed to increase the intake of selenium, especially in areas where selenium is scarce or in a particular disease.Monitoring and adjustment: Selenium intake needs to be appropriate, and overingestion can also lead to poisoning. It is therefore recommended that selenium supplementation be carried out under the guidance of a specialist doctor.In conclusion, beryllium is a key nutrient for thyroid health, and it plays an important role in the synthesis of thyroid hormones, protection against oxidation, immunisation regulation and the prevention of thyroid diseases. Ensuring adequate intake of selenium is essential to maintaining thyroid function and overall health. However, the intake of selenium should be careful and follow professional medical advice to avoid potential side effects.
