What is Selenium?
Selenium is a trace mineral that is very important for our body. It helps make special proteins, called selenoproteins, which are important for preventing cell damage. Knowing about selenium shows us how it helps keep us healthy.
Overview of Selenium as a Trace Mineral
Selenium is needed by the body in small amounts. Adults should get about 55 micrograms of selenium a day. Men and women need slightly different amounts, 0.075mg for men and 0.06mg for women.
It helps with things like making babies, keeping our thyroid working right, and fighting off diseases. The Department of Health says that less than 0.35mg a day from supplements is okay. But too much can cause problems, like not getting enough of other nutrients.
Importance in Human Health
Selenium does more than just nutrition. It makes our immune system work better and protects our cells from getting damaged. Not having enough selenium is rare in places with a lot of food but can still happen.
In some parts of China and Tibet, not getting enough selenium is still a problem. People living there need to make sure they eat the right foods to get enough selenium.
Sources of Selenium in Diet
It’s good to know where selenium comes from to keep its levels right in our body. The best foods for selenium are:
- Brazil nuts
- Tuna
- Poultry
- Beef
- Eggs
Brazil nuts are super high in selenium. Just one can give you all you need for the day. But, it’s important to not eat too much, especially from supplements, as it could be harmful.
