1. Introduction Dietary reference values give information about the amount of nutrients necessary to take in for normal functioning of the body, growth, and to prevent (deficiency) diseases. Recently, European Food Safety Authority (EFSA) finished their job to set dietary reference values [2]. In the Netherlands, the Health Council sets these values. In 214, ad interim values were set [4]. The ad-interim dietary reference values as set by the Health Council of the Netherlands in 214 and the EFSA s dietary reference values differ for some nutrients. Since 216, a commission of the Health Council is evaluating the EFSA s dietary reference values for the Dutch situation. The aim of our study was to estimate the habitual intake of micronutrients in the Dutch adult (19-5 years.) population. An additional objective was to visualize, how the habitual intake distribution relates to the Dutch ad-interim and the EFSA s dietary reference values. For our study data from the Dutch National Food Consumption Survey 27-21 [5] was used and combined with food composition data from NEVO-213 [6]. This memo gives a brief overview of the methodology used and general interpretation guidelines for the results. The results are presented in tables and figures by each micronutrient. Only the micronutrients for which there is an ad-interim Dutch and EFSA s dietary reference value are included, as well as only micronutrients for which it was possible to estimate the intake of Dutch adults. This was the case for vitamins A, B 1, B 3, B 5, B 6, B 12, C, D, E, and K, folate, as well as for, calcium, phosphorus, potassium, magnesium, copper, selenium, iron, and zinc. The research described in this memo was conducted by order of the Dutch Ministry of Health, Welfare and Sports (knowledge question 5.4.3 (217-218) additional research ) to support the commission Nutrition of the Health Council of the Netherlands and the by this commission established working group on dietary reference values.

2. Methods Data from the Dutch National Food Consumption Survey 27-21 was used in this study. Details of this study are described in detail elsewhere [5, 7]. In brief, this survey was conducted among children and adults aged 7-69 years. All subjects were interviewed twice about their food consumption of the previous day (24-hr recall). To estimate the micronutrient intake, the consumption data were combined with food composition data of NEVO 213 [6]. For our study, only data were used from Dutch adults aged 19-5 years. The habitual intake of micronutrients from foods was estimated. The micronutrient intake from dietary supplets was not included. For the micronutrients with a dietary reference value expressed per unit of energy intake, the ratio of the micronutrient and energy intake was calculated prior to estimating the habitual intake. The habitual intake is the long-run average intake (also referred to as usual intake). The population distribution of habitual intake only includes between-person variation and no withinperson variation. To estimate the habitual intake from 24-hr recall data on two nonconsecutive days, the statistical program to assess dietary exposure (SPADE version 2.33.1) was used [8]. For all micronutrients, the SPADE 1-part model was applied, as virtually the whole population daily consumed all micronutrients. In the SPADE 1-part model, only the habitual intake amounts are estimated and not the habitual intake frequency, as this frequency is daily for all subjects. The habitual intake distribution is presented separately for and wo by means of the average intake and the intake at the 5 th, 25 th, 5 th (median), 75 th, and 95 th percentile. All results were weighted for small deviations in socio-demographic characteristics compared to the Dutch population in 28, and for deviations from an equal distribution over the seasons and days of the week. Bootstrap (1 iterations) was used to quantify the modeling uncertainty and presented as 95%-confidence interval. The habitual intake distributions were compared with the Dutch and EFSA s dietary reference values [2, 4]. There are several types of dietary reference values available: average requiret (EAR), recomded daily allowance (RDA), and adequate intake (AI). The different organizations use their own specific terminology for the same type of DRVs. An overview is presented in Box 1. For this research the proportion lower or equal to the average intake was estimated using the EAR-cut point approach [3]. Based on several underlying assumptions, this proportion is a valid estimate of the proportion of the population with an inadequate intake. In addition, the percentile of the intake distribution at which the RDA is reached was calculated. For micronutrients for which no EAR was set, the percentile of the intake distribution at which the AI is reached was calculated. With an AI only a qualitative evaluation is possible. If the median habitual intake is above the AI the risk of inadequate intake is considered to be low in the population. However, if the median habitual intake is below the AI no statet can be made about the adequacy of intake in the population. In that case, additional research e.g. nutritional status, is required to evaluate the adequacy of the intake. An overview of guidelines for the interpretation is presented in Box 2. Version: 1.

Under assumption of a normal distribution of the individual requirets, it is calculated as the (estimated) average requiret (A) + 2 SD (virtually 97.5%) C: When the underlying data is insufficient to set an (estimated) average, requiret an adequate intake is established instead. This is a single estimate without knowledge on the distribution of individual requirets in a population. The AI is the intake level associated with adequate (markers of) health in (almost) all individuals. It is expected to be equal to or higher than the RDA/AH/PRI/RI if there would have been sufficient data to set such a value. D: The level of intake that could lead to clinical signs of deficiency in virtually the whole population. It is set as the (estimated) average requiret 2 SD. Version: 1. Page5 of 36
probability adverse health effect Box 2. Interpretation of evaluation of nutrient intake in a population with dietary reference values With dietary reference values, it is possible to assess the adequacy of a population s intake to some extent. The way of evaluating the nutrient intake of a population depends on the type of dietary reference value. Figure A shows an overview of the different dietary reference values and their mutual relationship as well as their relationship with the habitual intake and probability of adverse health effects. EAR RDA AI* UL NOAEL* LOAEL* uncertainty factor 2*SD (requiret) uncertainty factor (habitual) intake Figure A. Schematic overview of the relationship between (habitual) intake and probability of adverse health effects including the different nutritional reference intakes [1]. * AI, NOAEL and LOAEL do not have exact relation with requiret (or intake); therefore the lines are dashed and surrounded by a shaded area. EAR: estimated average requiret; RDA: recomded daily allowance; AI: adequate intake; UL: tolerable upper intake level; NOAEL: no observed adverse effect level; LOAEL: lowest observed adverse effect level; SD: standard deviation. Evaluating with average requiret The average requiret can be used to estimate the proportion of the population with inadequate intakes using the EAR-cut point approach [3], as long as several assumptions are met. The idea behind the EAR-cut point approach is that the proportion below the average requiret predicts the proportion of the population with intakes below their individual requirets. This is a valid prediction if the intake and requiret are independent, the distribution of requirets is symmetrical, and the variance of the distribution of requirets is small compared to the variance of the intake distribution. As such, this method will not provide valid estimates of the proportion with inadequate intakes for energy as the intake and requirets are not independent. As well as for iron, for which there is a non-symmetrical distribution of the requirets, especially for wo of childbearing age. A general rule of thumb is that with small proportions (i.e. < 1%) no public health Version: 1. Page6 of 36
Continue Box 2. Interpretation of evaluation of nutrient intake in a population with dietary reference values problem from inadequate intakes is expected. Evaluating with adequate intake An adequate intake can only be used for qualitative evaluation of the nutrient intake. If the population habitual median intake is above the adequate intake the risk on inadequate intake in the population is judged to be low. If this is not the case, no statet about the adequacy can be given, additional research is needed, e.g. nutritional status. Evaluating with Recomded Daily Allowance The recomded daily allowance cannot be used to predict inadequate intake at a population or individual level. However, it can be used as a guideline for individual advice. The individual requiret is unknown, but this value would be sufficient for most people. As it is expected to be the amount which is sufficient to full-fill the requiret of 97.5% of the population. Consequently, it is a higher amount than most people would require based on their individual requiret, if known. On the other hand, for some people it is still not sufficient. Version: 1. Page7 of 36
3. Results The results are described separately for each micronutrient for which EFSA did set a dietary reference value recently and for which it was possible to estimate the habitual intake. In paragraphs 3.1 to 3.11, the vitamins are presented followed by the minerals in paragraphs 3.12 to 3.19. For some micronutrients, the unit of the ad interim dietary reference values set by the Dutch Health Council differs from the unit used by EFSA, for these micronutrients the results are presented in both units in separate Tables and Figures. Otherwise, the results are presented in the same Table and Figure. All results are presented separately for and wo. Version: 1. Page8 of 36
3.1 Vitamin A The EFSA s reference values are expressed in retinol equivalents (RE), while the ad interim Dutch reference values of the Health council are expressed in retinol activity equivalents (RAE). The difference is the way in which the pro-vitamin A carotenoids are converted using conversion factors before adding to the retinol intake. As a result, the vitamin A intake expressed in RAE is lower than when expressed in RE. EFSA: Retinol-equivalent (RE) 1 µg RE = 1µg retinol = 6 µg β-carotene = 12µg other carotenoids with provitamin A activity Ad-interim Health Council: Retinol-activity-equivalent (RAE) 1 µg RAE = 1 µg retinol = 2 µg β-carotene from supplets = 12 µg of β- carotene from food = 24 µg other carotenoids met provitamin A activity As the Dutch Health Council set different reference values compared to the ad interim Dutch reference values and the EFSA s reference values, a second figure is added to show the habitual vitamin A intake distribution with these newly set reference values (Figure 2).

Both dietary reference values for vitamin B 3 are expressed as niacin equivalent (NE). In NEVO 213, only data on nicotinic acid (i.e. in Dutch nicotinic acid amide) and not tryptophan are included. The calculated vitamin B 3 intake only concerns the intake of nicotinic acid. Niacin-equivalent (NE): 1 mg NE = 1 mg nicotinic acid = 1/6 mg tryptophan Table 9.

3.1 Vitamin E The vitamin E intake is presented as total vitamin E. Conversion factors are used to add up the different tocopherols. However, the dietary reference values have been expressed in another unit. The total vitamin E intake will be slightly higher than the intake of α- tocopherol (equivalents), but within total vitamin E, α-tocopherol is the largest source. Total vitamin E (NEVO): = mg α-tocoferol*1 + mg β-tocoferol*,4 + mg γ-tocoferol*,1 + mg δ- tocoferol*,1 α-tocoferol (EFSA): 1 mg all-rac-α-tocoferol =,5 mg RRR-α-tocoferol. α-tocoferol-equivalents (ad-interim Health Council): Vitamin E activity is shown as α-tocopherol. Only α-tocopherol in food and 2R-αtocopherol in food supplets contribute to vitamin E activity. The following conversion factors apply to supplets:,5 for all-rac-α-tocoferol,,455 for allrac-α-tocoferyl acetate and,91 for RRR-α-tocoferyl acetate. Table 24.

3.11 Vitamin K A difference between the dietary reference values of vitamin K is that the standard of EFSA has only been established for vitamin K 1 and the ad interim dietary standard of the Health Council has been established for both vitamin K 1 and K 2. Since 213 vitamin K values (total K 1 + K 2 ) are included in the Dutch nutrient database (NEVO-213) for a number of food groups only (i.e. vegetables, fruit, legumes and dairy products), the calculated vitamin K intake will therefore be an underestimation of the actual intake. The food groups for which vitamin K data are available are seen as the most important sources of vitamin K. The coverage ratio for vitamin K 1 is slightly lower than for total vitamin K (= K 1 +K 2 ). Table 26.

3.19 Zinc The EFSA dietary standard of zinc is derived for different categories of phytate intake. There are no data available about the phytate intake in the Netherlands. Therefore, in this comparison, the phytate intake is based on the average of the four categories tioned by EFSA and the associated average requiret for zinc. Table 42.
