Selenium has a positive effect on the growth and strengthening of the human hair and nail plate. Scientists have determined that it is also able to block the rapid spread of the AIDS virus.

That is why it is almost impossible to find plant-type products rich in selenium. By the way, during the heat treatment of vegetables, selenium is destroyed.
And what should those who do not eat meat do? There is an exit, of course. Eat garlic. However, it is the fresh product that is rich in selenium, and if garlic is added when cooking stewed or fried foods, its useful properties are lost.
