The more selenium people had in their toenails, the lower their risk of type 2 diabetes. People with the highest level of selenium had a 24% lower risk of developing diabetes.
Researchers assessed the selenium levels in people’s toenails because toe nail selenium reflects the amount of selenium in the body as a whole.
Selenium is a building block of a powerful antioxidant called Glutathione Peroxidase (GSH-Px). GSH-Px is manufactured within each cell of the body and protects cells from damage. GSH-Px may help protect the body from harmful changes that lead to type 2 diabetes.
