Getting adequate selenium in your diet or from your multivitamin could help you and everyone around you stay healthier. In lab studies, researchers at the University of North Carolina in Chapel Hill found that when viruses pass through bodies’ deficient in selenium, they can mutate into more damaging forms, that can infect even those with a healthy diet. Earlier studies have shown the same danger with a vitamin E deficiency.
According to Spallholz (Researcher in the Department of Food and Nutrition in the College of Human Sciences at Texas Tech University) all flu viruses like the Hong Kong flu, Chinese flu that come to North America, normally are up-and-coming from Southeast Asia and budding from regions of the world which are low in selenium.
