Summaries for deriving DRVs for nutrients
The sections below summarize the evidence for setting DRVs for all the nutrients considered in NNR2023. The text on dietary intakes is mainly based on the background paper by Lemming and Pitsi (2022). The text in the sections on main functions, indicator for recommended intake, main data gaps, and deficiencies and risk groups are based on the corresponding nutrient background papers. All nutrient backgrounds papers are clearly cited to credit all authors. As described in this report, qualified systematic reviews are the main fundament for assessment of evidence. All qualified systematic reviews included in each of the nutrient summaries are listed in Table 1 and Appendix 2.
While the recommendations are mainly based on the corresponding nutrient background papers (Table 6 and 7) as well as qualified systematic reviews (Table 1), the NNR2023 Committee has the sole responsibility for the text in the nutrient sections, the principles, methodology, calculations and the final setting of all DRVs. All final DRVs were set unanimously by the NNR2023 Committee.
For each nutrient, the setting of DRVs is summarized in a graphical abstract. All DRVs in the graphical abstracts refer to the age group 25-50 years. For information about scaling to other life-stage groups, please refer to table 12–15 and 17–20 and appendix 5.
Nutrient intakes should not be interpreted as absolute; rather, they are estimates with uncertainty, and depend on factors such as food consumption, survey methods, reporting errors, countries’ food databases, calculation procedures, and similar. The range of estimated average intakes, excluding intake from dietary supplements, in the Nordic and Baltic countries is given in the text. Sources for nutrient intakes are mainly based on Nordic and Baltic food databases (Lemming & Pitsi, 2022).
