Micronutrient Bioavailability: Priorities and Challenges for Setting Dietary Reference Values


American Journal of Clinical Nutrition.  2010;91(Suppl 5):1413S-1491S

Proceedings of a workshop hosted by EURRECA and the Addition of Nutrients to Food Task Force

The aim of the workshop was to address topical issues, in particular those that linked bioavailability with the derivation of micronutrient requirements and dietary recommendations, to identify gaps in knowledge and to conside research priorities.

Several generic research priorities were identified, including improving the quality of dietary surveys/food composition tables, the need for more metabolic studies that use stable isotopes and high-quality longer-term interventions, and the development of multifactorial mathematical models. Among the common recurrent factors identified as important were polymorphisms/genotype, consideration of the whole diet, chemical form of the micronutrient, and the determination of physiologic requirements.

The involvement of all participants in the structured discussions ensured a broad overview of current knowledge, state-of-the-art research, and consideration of priorities for future research.
