Selenium supplements: Do they increase my diabetes risk?

Can selenium supplements increase my risk of diabetes?

- George / North Dakota

Answer

It's unclear whether selenium supplements increase your risk of developing type 2 diabetes. You may have heard about a recent study which reported that people who took a selenium supplement daily for about eight years increased their risk of type 2 diabetes by 50 percent. The study's findings are preliminary and need further confirmation.

Selenium is an antioxidant mineral that may contribute to fighting off chronic illnesses such as cancer and heart disease. It also helps boost your immune system and regulate your thyroid function, which is essential for your metabolism. In the United States, selenium is plentiful in foods including bread, pasta, nuts and meat. Most Americans can get the recommended daily allowance of selenium in their diets without making any changes in their diet or adding a supplement.

Until more research is completed, it probably is not necessary to add selenium supplements to your diet. If you are concerned about your selenium intake, ask your doctor about the risks and benefits of taking these supplements.
