Selenium is an essential mineral for our bodies, essential for several functions that maintain good health. Although necessary in small ways, selenium plays an important role in maintaining the body's balance, acting as an antioxidant, helping to protect cells from damage, and strengthening the immune system. In this article, we'll explain what selenium is, when supplementation may be necessary, the benefits and risks of this practice, and present foods rich in this mineral that can be included in the diet.
The importance of selenium for the body
Selenium is a mineral micronutrient with antioxidant action, essential for protecting cells against the harmful effects of free radicals, which can accelerate aging and the onset of various diseases.
Furthermore, selenium contributes to proper thyroid function, aiding in the production and regulation of hormones that control metabolism. Its role is also essential for strengthening the immune system, increasing the body's ability to defend itself against infections.
In which situations is selenium supplementation indicated?
Although selenium is present in many foods, some people may be at risk of deficiency and require supplementation. This occurs in cases where the diet is insufficient or in conditions that impair the absorption of the mineral, such as intestinal diseases. Furthermore, people living in regions where the soil is naturally low in selenium, and consequently, cultivated vegetables also have low levels of the mineral, may need to report this deficiency.
Finally, there are situations of greater metabolic demand, which must be individually assessed by health professionals before recommending the use of supplements.
The main benefits and precautions when supplementing selenium
Proper selenium supplementation can provide several health benefits, including strengthening the immune system, protecting cells from oxidative stress, supporting fertility, and improving cardiovascular health. However, it's essential that supplementation be done in a controlled manner, as excess selenium can lead to unwanted effects such as toxicity, hair loss, gastrointestinal discomfort, and even neurological problems.
Therefore, professional guidance is essential to ensure safety.
How to get selenium naturally through food
Before opting for supplementation, it's worth remembering that it's possible to achieve adequate selenium levels by consuming foods rich in this mineral. Brazil nuts are one of the most potent sources, with just one nut already meeting the daily recommended intake. Fish and seafood, meat, eggs, and whole grains are also good options for meeting your daily needs, in addition to providing other important nutrients for the body.
Selenium is a vital element for the proper functioning of the body, participating in processes that influence metabolism, immunity, and cell protection. Despite the benefits of supplementation in certain cases, the best way to ensure health is to maintain a balanced and diverse diet containing natural sources of selenium. Whenever in doubt about the need to take this mineral, it is recommended to seek additional guidance from a healthcare professional.
