Selenium may cut risk of arthritis

New York: Researchers in the US believe that low levels of the mineral selenium could increase the risk of osteoarthritis in the knees.

Levels of selenium were measured in the toenail clippings and those with high levels were found to have half the risk of developing severe osteroarthritis in their knees.

The conclusion is that the mineral acts as a protective antioxidant but more research is necessary to prove this.
