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.
