Research suggests that selenium supplements may improve glucose metabolism.
The investigators examined the incidence of type 2 diabetes among participants in a clinical trial designed to assess the effects of selenium supplementation on skin cancer. Participants randomly assigned to receive selenium were more likely to develop type 2 diabetes than were those assigned to placebo.
Diabetes was a secondary outcome of the original trial. The diagnosis was self-reported, and most participants were older and white.
Long-term selenium supplementation appears to increase the risk for type 2 diabetes.
The value was derived from the log-rank test.
