Selenium


The main carrier of selenium in the food chain are plants. However, as the amount of selenium in the subsoil varies we can’t be sure about how much of this element is contained in the plants we eat. Man receives this nutrient element through plants and the meat of the animals that eat plants. Thus, the area where plants are grown and animals fed is related to the availability of selenium in nutrition.

Brazil nuts are known for their selenium content because they grow in an area with plenty of selenium in the subsoil. Wheat and meats as dietary selenium sources considered to be the most important.

Selenium is a trace element, an essential micronutrient that has many antioxidant properties and normally should be combined with vitamin E as in this way it strengthens the thyroid, the pancreas, the liver and the immune system.  Moreover, it is very useful for athletes and helps them a lot, since it protects them from muscle problems caused by free radicals after intense exercise.

It is an important trace element essential for the production of glutathione peroxidase, an important enzyme which is found in every cell of our body.

Generally, it is necessary to our body because it stops aging and the collapse of the immune system.

Without selenium, our cells are vulnerable to viruses, cancer,  heart disease, etc.

It’s a powerful antioxidant with a variety of anti-aging properties.

Selenium participates in the formation of glutathione peroxidase (enzyme that neutralizes free radicals that oxidize fat cells).

Researches about its anti-cancer activity (chemoprotectant) as far as breast, bowel, liver, skin, trachea and lung cancer is concerned, have proved it.

It protects human body against heart diseases.

It prevents the oxidation of LDL.

It combats infections, anxiety, depression, and fatigue.

It regulates the thyroid, the liver and the production of prostaglandins.

The daily intake of 100mcg day is considered to be sufficient.

As we grow older the needs (7% after sixty, 24% after the seventy-five) for selenium become greater.

Foods that contain selenium are Brazil nuts, garlic, sunflower seeds, organic grains, fish, shellfish, liver, etc.

If we use selenium in the form of food supplements we should make sure that it is chelated for maximum absorption.

Finally, we should point out that the preventive effects of selenium are much stronger and more valuable than the therapeutic ones.

In addition, studies have shown that regular intake of selenium for a long time, up to 500mcg, does not cause any toxicity symptoms at all.
