Fuel your body regularly with the valuable element selenium, which has antioxidant properties and the ability to protect against very serious diseases.
Selenium is exceptionally important for excellent immune system function, especially when it needs to be "switched on" to deal with a severe infection.
When eating right, the daily dose of selenium for an average man is about 70 mcg, and for women - 40-50 mcg. A tuna fish sandwich contains 138 mcg of selenium.
All fish are rich in selenium, as well as river crabs, oysters, and whole wheat bread.
Don't overindulge in dietary supplements that contain selenium, because the total daily dose must not exceed 200 mcg, as advised by experts.
Another key element that helps the immune system fight off infections, which is especially important during the winter season, is zinc. It is a crucial part of the immune system.
In fact, it is thought that it is the most important element for it. Zinc deficiency can lead to a decrease in the production of white blood cells, which destroy the microscopic particles that make their way into the body.
Zinc aids in the production of vitamin D in the body, which also boosts the immune system. In order to get your daily 15 mg, you can focus on eating lean red meat, oysters, milk, oatmeal, whole wheat bread, eggs and chicken or duck meat.
Avoid taking dietary supplements, which would provide your body more than 40 mg daily. When the daily dose is exceeded, zinc can significantly lower immune system function.
