Too Much Maganese A Cause for Concern/The Genealogy Phone In
Too Much of a Good Thing?: The chemical element manganese occurs naturally in food, water and soil. Among other things, our bodies use it to metabolize carbohydrates.

It's the first study of its kind to focus on the potential risks of exposure to manganese. We spoke with Dr Maryse Bouchard,, the lead author of the study.
