Manno, Switzerland, 13 June 2012—CRN-International (CRN-I), the international arm of the Council for Responsible Nutrition, will return to Kronberg im Taunus, Germany, on Saturday 01 December, to host its third scientific symposium. Taking place at the Schlosshotel Kronberg, the symposium, titled “Nutrient Reference Values for Bioactives? —New Approaches,” is designed to bring together regulators, policymakers, nutrition scientists and academics to engage in science-based discussions on nutrition issues related to the activities of the Codex Alimentarius Committee on Nutrition and Foods for Special Dietary Uses (CCNFSDU).

“The purpose of the symposium is to advance the understanding of the relevant science to the regulatory and policy-setting community of Codex,” said John Hathcock, Ph.D., senior vice president, scientific and international affairs, CRN-I.

The symposium will feature a keynote address on the framework and definitions of the U.S. Institute of Medicine (IOM) Dietary Reference Intakes (DRIs) from John Erdman, Ph.D., University of Illinois.  Dr. Erdman was previously a member of the IOM standing committee on the scientific evaluation of DRIs for essential nutrients. His remarks will focus on how the IOM DRI framework may be adapted for establishing nutrient reference values for bioactives.

Additional speakers include:

  • Prof. Hans Biesalski, University of Hohenheim, addressing intervention and epidemiological data that can be used to establish nutrient reference values (equivalent to the Recommended Daily Allowance in the U.S.);
  • Kathleen Ellwood, Ph.D., formerly with the U.S. Department of Agriculture and the Food and Drug Administration, on the use of dietary intake patterns for healthy persons to identify “Adequate Intake,” as defined by the IOM;
  • Stephen Beatty, M.D. and Elizabeth Johnson, Ph.D. , who will both speak about the positive health impacts of lutein and zeaxanthin;
  • Roberto Marchioli, M.D., and Lotte Lauritzen, Ph.D., on omega-3 fatty acids; and
  • Dr. Hathcock on safety considerations that should be evaluated when establishing government-recommended intakes for nutrients.

 The CRN-I symposium will precede the official meeting of the CCNFSDU.  The full agenda is posted on the CRN-I website and participation is by invitation-only.  There will be no registration fee for government regulators, delegates to Codex and full-time academics, and a nominal fee for other attendee categories. 

Summary proceedings of the first conference were published in Regulatory Toxicology and Pharmacology and those of the second conference were published in European Journal of Nutrition. CRN-I plans to publish a summary document of this third conference.
