Previously it was believed that selenium prevents the development of cancer, but scientists have proved that it is not so, reports BBC. This conclusion was made by the staff of the organization The Cochrane collaboration in the analysis of 55 surveys, which involved more than a million people.

In addition to the inefficiency of selenium, experts determined its toxicity with prolonged intake of appropriate additives. Survey leader Dr. Gabriel Dennert of the Institute for Interdisciplinary Health Research in Germany emphasizes: "Selenium in small quantities is vital. It helps build a strong immune system that fights infections and diseases. Selenium is found in a variety of foods - in Brazil nuts, tuna and pasta.

Additives, as well as other vitamins do not work as a protection against cancer, on the contrary, increasing the risk of cancer in some cases ".

In turn, Inka Ebo of the British Cancer Research Center is confident that people should be more careful about taking supplements, thinking twice before starting the course, relying on selenium. The best way to make up for the shortage of trace elements is food. It is nutrition, according to the expert, will work as a protection against cancer. Most healthy people do not need to take supplements at all.
