Selenium
Selenium, an essential trace element, is found in natural soils and in many foods. The human body needs selenium for various biological functions, including protection against oxidative stress, support of the immune system and as a cofactor for enzymes.
Selenium in Food
Selenium is found in both plant and animal foods. Good sources of selenium are generally fish, meat, eggs, but also pulses (beans, lentils and peas), asparagus, broccoli, mushrooms, white cabbage, garlic, onions and Brazil nuts.
With the help of a balanced and healthy diet, the daily requirement of selenium can be completely covered. However, Swiss soils are quite poor in selenium, which is why the plants that grow on this soil also contain less selenium. As a result, many people can quickly slip into a selenium deficiency.
Effect of Selenium
Among other things, selenium has a decisive effect on thyroid function and DNA synthesis. A healthy selenium level can therefore reduce the risk of certain cancers and thyroid diseases.
The fields of application of selenium range from heart and thyroid health to cancer prevention.
Intake as a Dietary Supplement
In addition to natural food intake, selenium is also used in nutritional supplements to quickly compensate for an existing deficiency. However, careful attention should be paid to the dosage, as selenium can be toxic in high doses.
Therefore, the indication, selection of the product and the dosage belong in the hands of an experienced doctor.
In order to ensure an optimal effect, it is important that the intake is always carried out under medical advice and after an individual blood test.
Selenium can be determined in serum or whole blood. A whole blood analysis is more meaningful and should be preferred.
