Selenium helps reduce type 2 diabetes

Increased levels of selenium in the body may be associated with a 25% reduction in the risk of type 2 diabetes.

Data from 3,630 women and 3,535 men indicated that increasing levels of selenium in toenails were associated with lower risks of diabetes, with the relationship appearing to be linear, according to findings published in Diabetes Care.

Selenium is an antioxidant has multifarious roles including building heart muscles and healthy sperm. Moderate deficiency in selenium may have long-term detrimental effects (FASEB Journal 25:1793-1814, 2011).

Over the course of the study the researchers documented 780 new cases of type 2 diabetes. The highest average levels of selenium (Se) in toenails were associated with a 24% reduction in the risk of the disease.

“At dietary levels of intake, individuals with higher toenail Se levels are at a lower risk for [type 2 diabetes],” they concluded.
