    Title
    Samenstelling van voedingsmiddelentabellen met gehalten aan retinol en beta-caroteen, vitamine E en pectine ten behoeve van o.a. de Zutphen-studie
    Translated Title
    [Composition of food tables with contents of retinol, beta-carotene, vitamin E and pectin for a.o. the Zutphen Study.]
    Publiekssamenvatting
    Abstract niet beschikbaar
    Calculations of nutrient intakes from information about food intake in the Zutphen Study are usually carried out using the NEVO-table, an extended version of the Netherlands Food Table. The table issued in 1989/90 has been used as the most recent one. However, this table contains no information on contents of retinol, beta-carotene, vitamin E, and pectin, whereas information on these nutrients is very valuable for our epidemiologic analyses. Additional food tables have been composed to fill this gap. This was done by using recent data of chemical analyses on Dutch foods, using food tables from other countries, by deducting from other values, and by calculations based on recipes. The resulting food tables contain 999 different foods. These are all the foods that were reported to be used during the nutritional surveys of the Zutphen Study in 1985 and in 1990. Of these 999 foods, 972 occur in the NEVO-table, whereas 27 have a special code. Finally, for 8 foods it was not possible to report a value for retinal and/or beta-carotene, for 5 foods the vitamin E content was lacking, and for 9 foods the pectin content could not be found.

      Assessment of serum total 25-hydroxyvitamin D assay commutability of Standard Reference Materials and College of American Pathologists Accuracy-Based Vitamin D (ABVD) Scheme and Vitamin D External Quality Assessment Scheme (DEQAS) materials: Vitamin D Standardization Program (VDSP) Commutability Study 2.

      Camara, Johanna E; Wise, Stephen A; Hoofnagle, Andrew N; Williams, Emma L; Carter, Graham D; Jones, Julia; Burdette, Carolyn Q; Hahm, Grace; Nalin, Federica; Kuszak, Adam J; et al. (2021-06-28)
      An interlaboratory study was conducted through the Vitamin D Standardization Program (VDSP) to assess commutability of Standard Reference Materials® (SRMs) and proficiency testing/external quality assessment (PT/EQA) samples for determination of serum total 25-hydroxyvitamin D [25(OH)D] using ligand binding assays and liquid chromatography-tandem mass spectrometry (LC-MS/MS). A set of 50 single-donor serum samples were assigned target values for 25-hydroxyvitamin D2 [25(OH)D2] and 25-hydroxyvitamin D3 [25(OH)D3] using reference measurement procedures (RMPs). SRM and PT/EQA samples evaluated included SRM 972a (four levels), SRM 2973, six College of American Pathologists (CAP) Accuracy-Based Vitamin D (ABVD) samples, and nine Vitamin D External Quality Assessment Scheme (DEQAS) samples. Results were received from 28 different laboratories using 20 ligand binding assays and 14 LC-MS/MS methods. Using the test assay results for total serum 25(OH)D (i.e., the sum of 25(OH)D2 and 25(OH)D3) determined for the single-donor samples and the RMP target values, the linear regression and 95% prediction intervals (PIs) were calculated. Using a subset of 42 samples that had concentrations of 25(OH)D2 below 30 nmol/L, one or more of the SRM and PT/EQA samples with high concentrations of 25(OH)D2 were deemed non-commutable using 5 of 11 unique ligand binding assays. SRM 972a (level 4), which has high exogenous concentration of 3-epi-25(OH)D3, was deemed non-commutable for 50% of the LC-MS/MS assays.

      Veilige maximale dagdosering vitamine D in voedingssupplementen : aanvullende berekening bij een hogere vitaminering van smeerbare vetten

      Verkaik-Kloosterman J; Dekkers ALM; Ocke MC; P&V; V&Z (Rijksinstituut voor Volksgezondheid en Milieu RIVM, 2015-01-19)
      Vitamine D is belangrijk voor sterke botten en tanden. Het lichaam maakt zelf vitamine D aan als de huid aan zon wordt blootgesteld. Daarnaast is voeding een bron. Sommige voedingsmiddelen bevatten van nature vitamine D, maar deze vitamine wordt ook aan producten toegevoegd, zoals aan smeerbare vetten. Mensen die het risico lopen te weinig vitamine D binnen te krijgen, wordt aanbevolen om vitamine D-supplementen te slikken. Het gaat om jonge kinderen, vrouwen van 50 jaar en ouder, mannen van 70 jaar en ouder, mensen met een donkere huidskleur, zwangere vrouwen en mensen die onvoldoende buiten komen. Een andere manier om de inname te verhogen is om meer vitamine D toe te voegen aan voedingsmiddelen. Het maximumgehalte vitamine D dat in supplementen mag zitten, moet daar dan op worden aangepast. Het RIVM heeft berekend wat het effect is op de maximale dagdosering vitamine D in supplementen als het vitamine D-gehalte in smeerbare vetten, zoals margarine en halvarine, wordt verhoogd tot het huidige maximale wettelijke niveau. De vitamine D inname van de Nederlandse bevolking zal in dit scenario substantieel toenemen. De veilige maximale dagdosering vitamine D uit supplementen zal hierdoor iets afnemen. Dit is een aanvullende berekening naast eerder onderzoek uit 2013. De onderzoeken zijn uitgevoerd in opdracht van het ministerie van VWS. Op basis hiervan overweegt dit ministerie om de maximale gehaltes vitamine D in supplementen en/of verrijkte voedingsmiddelen te herzien. Sinds enkele jaren bestaat er een maximum voor de hoeveelheid vitamine D in supplementen, en voor de hoeveelheid die aan voedingsmiddelen mag worden toegevoegd. Deze maxima zijn bepaald om een te hoge inname te voorkomen. Een te hoge inname van vitamine D kan namelijk een te hoog calciumniveau in het bloed of de urine veroorzaken, wat bijvoorbeeld kan leiden tot nierstenen. De maximale gehalten zijn bepaald op basis van de 'aanvaardbare bovengrens'. In 2012 is de aanvaardbare bovengrens voor vitamine D door de European Food Safety Authority (EFSA) verhoogd voor personen vanaf 1 jaar.

      The vitamin B6 paradox: Supplementation with high concentrations of pyridoxine leads to decreased vitamin B6 function.

      Vrolijk, Misha F; Opperhuizen, Antoon; Jansen, Eugène H J M; Hageman, Geja J; Bast, Aalt; Haenen, Guido R M M (2017-10)
      Vitamin B6 is a water-soluble vitamin that functions as a coenzyme in many reactions involved in amino acid, carbohydrates and lipid metabolism. Since 2014, >50 cases of sensory neuronal pain due to vitamin B6 supplementation were reported. Up to now, the mechanism of this toxicity is enigmatic and the contribution of the various B6 vitamers to this toxicity is largely unknown. In the present study, the neurotoxicity of the different forms of vitamin B6 is tested on SHSY5Y and CaCo-2 cells. Cells were exposed to pyridoxine, pyridoxamine, pyridoxal, pyridoxal-5-phosphate or pyridoxamine-5-phosphate for 24h, after which cell viability was measured using the MTT assay. The expression of Bax and caspase-8 was tested after the 24h exposure. The effect of the vitamers on two pyridoxal-5-phosphate dependent enzymes was also tested. Pyridoxine induced cell death in a concentration-dependent way in SHSY5Y cells. The other vitamers did not affect cell viability. Pyridoxine significantly increased the expression of Bax and caspase-8. Moreover, both pyridoxal-5-phosphate dependent enzymes were inhibited by pyridoxine. In conclusion, the present study indicates that the neuropathy observed after taking a relatively high dose of vitamin B6 supplements is due to pyridoxine. The inactive form pyridoxine competitively inhibits the active pyridoxal-5'-phosphate. Consequently, symptoms of vitamin B6 supplementation are similar to those of vitamin B6 deficiency.
