selenium

As an antioxidant, the trace element selenium primarily binds free oxygen radicals and thus protects body cells from oxidative stress. Good sources of selenium are animal and vegetable proteins. Meat and fish, cereals, nuts and pulses as well as porcini mushrooms are particularly rich in selenium. It is also advisable to eat foods with a high content of vitamins A, C and E, as these improve the bioavailability of selenium in the body.
