    Gellert, Sandra; Ströhle, Alexander; Hahn, Andreas (London : BioMed Central Ltd., 2017)
    Background: Despite increased awareness of the adverse health effects of vitamin D deficiency, only a few studies have evaluated the vitamin D status (25-hydroxyvitamin D [25(OHD)]) of breastfeeding women and up to now, ...
  • Diet-dependent net endogenous acid load of vegan diets in relation to food groups and bone health-related nutrients: Results from the German Vegan Study 
    Ströhle, Alexander; Waldmann, Annika; Koschizke, Jochen; Leitzmann, Claus; Hahn, Andreas (Basel : S. Karger AG, 2011)
    Background/Aims:Dietary composition has been shown to affect acid-base homeostasis and bone health in humans. We investigated the potential renal acid load (PRAL) and the estimated diet-dependent net acid load (net endogenous ...
  • Effect of two different multimicronutrient supplements on vitamin D status in women of childbearing age: A randomized trial 
    Pilz, Stefan; Hahn, Andreas; Schön, Christiane; Wilhelm, Manfred; Obeid, Rima (Basel : MDPI AG, 2017)
    The German Nutrition Society raised in 2012 the recommended daily vitamin D intake from 200 to 800 international units (IU) to achieve 25-hydroxyvitamin D (25 (OH) D) levels of at least 50 nmol/L, even when endogenous ...
  • Impact of orientation on the vitamin D weighted exposure of a human in an urban environment 
    Schrempf, Michael; Thuns, Nadine; Lange, Kezia; Seckmeyer, Gunther (Basel : MDPI AG, 2017)
    The vitamin D3-weighted UV exposure of a human with vertical posture was calculated for urban locations to investigate the impact of orientation and obstructions on the exposure. Human exposure was calculated by using the ...
  • Nutritional status of flexitarians compared to vegans and omnivores - a cross-sectional pilot study 
    Bruns, Anja; Nebl, Josefine; Jonas, Wiebke; Hahn, Andreas; Schuchardt, Jan Philipp (London : BioMed Central, 2023)
    Background: In the Western world, there has been a notable rise in the popularity of plant-based, meat-reduced flexitarian diets. Nevertheless, there is insufficient data on the nutritional status of individuals following ...
  • Rationale and plan for vitamin D food fortification: A review and guidance paper
