Relevance of European alignment for micronutrients' recommendation regarding pregnant and lactating women, infants, children and adolescents: an insight into preliminary steps of EURRECA

EURRECA-Framework for Aligning Micronutrient Recommendations

There is currently no standard approach for deriving micronutrient recommendations, and large variations exist across Europe, causing confusion among consumers, food producers, and policy makers. More aligned information could influence dietary behaviors and potentially lead to a healthier population. Funded by the European Commission, EURRECA (EURopean micronutrient RECommendations Aligned) has developed methods and applications to guide Nutrient Recommendation Setting Bodies through the process of setting micronutrient reference values. The EURRECA approach is crystallized into its framework that outlines a standard process for deriving and using dietary reference values for micronutrients in a transparent, systematic, and scientific way. The 9 activities of the framework can be clustered into four stages (i) defining the problem, (ii) monitoring and evaluating, (iii) deriving dietary reference values, and (iv) using dietary reference values in policy making. The EURRECA framework should not be interpreted as a prescriptive description of a linear process, but as a structured guide for checking that all issues essential for deriving requirements have at least been considered.

The relationship between zinc intake and serum/plasma zinc concentration in children: a systematic review and dose-response meta-analysis

Recommendations for zinc intake during childhood vary widely across Europe. The EURRECA project attempts to consolidate the basis for the definition of micronutrient requirements, taking into account relationships among intake, status and health outcomes, in order to harmonise these recommendations. Data on zinc intake and biomarkers of zinc status reported in randomised controlled trials (RCTs) can provide estimates of dose-response relationships which may be used for underpinning zinc reference values. This systematic review included all RCTs of apparently healthy children aged 1–17 years published by February 2010 which provided data on zinc intake and biomarkers of zinc status. An intake-status regression coefficient () was calculated for each individual study and calculated the overall pooled and SE () using random effects meta-analysis on a double log scale. The pooled dose-response relationship between zinc intake and zinc status indicated that a doubling of the zinc intake increased the serum/plasma zinc status by 9%. This evidence can be utilised, together with currently used balance studies and repletion/depletion studies, when setting zinc recommendations as a basis for nutrition policies.
