An expert on metabolic control and type 2 diabetes, Hallberg is also the executive director of the Nutrition Coalition, a nonprofit organization that aims to educate the public and policymakers about the need to strengthen national nutrition policy so that it is founded upon a comprehensive body of conclusive science, and where that science is absent, to encourage additional research.
