Selenium
Selenium has a similar function in the human body to vitamin E: it is part of an enzyme that binds free radicals that are formed when fatty acids are damaged by oxygen. Selenium is also involved in the formation of the thyroid hormone.
Selenium is an essential trace element, which means that on the one hand it is vital and on the other hand it is only required by the body in trace amounts. However, this small amount must be supplied daily through food, as the body cannot produce selenium itself.
Good sources of selenium are animal and vegetable proteins. Offal, meat and fish, cereals, nuts and pulses as well as porcini mushrooms are particularly rich in selenium. A high-quality dietary supplement can also help to cover your selenium requirements.

The selenium content in plants depends on the selenium content of the soil. Germany is well in the middle of the field. People who eat a low-protein, vegan or vegetarian diet usually get too little selenium. Smoking, alcohol, chronic inflammatory bowel disease and a long-term one-sided diet are parameters that can lead to a selenium deficiency.
