Selenium Protects Men Against Diabetes
The role of selenium in diabetes has been controversial, with some studies suggesting that it raises diabetes risk and others finding that it is protective. Now, research published in BioMed Central's open access journal Nutrition and Metabolism, has shown that, for men, high plasma selenium concentrations are associated with a lower occurrence of dysglycemia.
Tasnime Akbaraly, from the University of Montpellier, worked with a team of researchers to follow 1162 healthy French men and women for nine years, monitoring plasma selenium concentrations and incidence of dysglycemia. She said, "Our results showed that for French elderly males, having plasma selenium concentrations in the top tertile of the population distribution (1.19-1.97 Ã¼mol/L) was significantly associated with a lower risk of developing dysglycemia over the following nine years".
