Selenium

For many years selenium was considered a strong poison.And so it is in fact, but only if the dose of this bioelement is too large.In a small amount it neutralizes free radicals and activates various biochemical transformations of the system.Selenium is a microelement that protects the body against cancer and old age.Research by American and Finnish scientists showed that patients with cancer had surprisingly low levels of selenium in the blood.Lack of selenium in the body was associated with a higher incidence of tumors of the digestive tract, kidneys and bladder.Selenium prolongs the lives of patients with cancer treated with radiation or cytostatic agents.

Selenium

Selenium deficiency in the body may cause growth disturbance, damage to blood vessels, eye cataracts, hair loss, muscle degeneration, damage to the pancreas, liver and heart muscle.In areas poor in this bio-element, eg in China and Siberia, there is a heart condition (myocardiopathy) called Keshan’s disease.

Selenium has properties that stimulate the human immune system and prevents poisoning of heavy metals such as cadmium, bismuth and mercury.He makes non-toxic connections with them, easily excreted from the body.

The lack of selenium in the body occurs not only in cancer patients but also in liver cirrhosis and bowel diseases as well as in children fed with artificial nutrients and alcoholics.Myocardial infarction, atherosclerosis or coronary heart disease are other diseases that may be accompanied by a decrease in selenium reserves in the body.

Selenium

Modern civilization systematically depletes the human body in selenium.Its main source are cereal grains and fodder plants.Meanwhile, the growing shortage of selenium in the soil, as a result of acid rain and heavy metal contamination, affects its low content in agricultural crops.

A good source of selenium are marine products, such as fish, crabs and shrimps as well as beef, pork and veal kidneys.As wheaten products, wheat germs, wheat bran, corn kernels, tomatoes, mushrooms, garlic are recommended.Systematic consumption of whole grain breads (wholemeal bread) covers the body’s need for selenium.Both yeast and beer yeast are rich in selenium.Selenium is better used in the body if it is given in combination with vitamin E.
