Selenium, an antioxidant chemical element and enemy of human cancer/Σελήνιο Το Μοναδικό

Selenium is an important chemical that may protect cells against chemicals, pollution and the negative effects that the environment may have on human health, as indicated by Mohamadian Shahzad, a Persian specialist in nutrition and dietetics.

"Selenium is considered a substance with high antioxidant properties and is important in preventing human cancer," said Mohamadian.

Similarly, he added that "this supplement prevents the absorption of some heavy metals and their potential toxicity as well as environmental radiation such as mercury, silver and thallium, reducing the potential damage they may have on the health of the human body."

The walnut, salmon, brown rice, chicken meat and beef, whole wheat bread, skim milk and most nuts are the main dietary sources of selenium according to the  Iranian nutritionist.
