| Popis: | Hypovitaminosis D is prevalent worldwide, with many failing to achieve the recommended nutrient intake (RNI) for vitamin D (10- 20μg/d)(1). Moreover, the COVID-19 pandemic has re-emphasised the need to avoid vitamin D deficiency to help maintain immune function(2) and the urgent need for food-based strategies to help address this(3). The aims of the current study were to 1) determine any changes to vitamin D intake and status over a 9-year period, and 2) apply dietary modelling to predict the impact of vitamin D bio-enrichment of pork and pork products on population intakes in the UK. Data from the National Diet and Nutrition Survey (NDNS) Rolling Programme Year 1-9 (2008/09-2016/17) were analysed using SPSS to determine nationally representative mean vitamin D intakes and 25(OH)D concentrations [a robust biomarker of vitamin D status]. Subgroup analysis investigating variance in sex, age and season was conducted. Informed by previous studies(4), four theoretical dietary modelling scenarios of vitamin D pork bio-enrichment were analysed (vitamin D content + 50/100/150/200% vs standard). Vitamin D intake in the UK population has not changed significantly from 2008 to 2017 yet, over the same period significant gender difference (M 2.66 ± 1.99μg/d and F 2.30 ± 1.66μg/d, p < 0.05) and seasonal variation in the mean 25(OH)D concentrations were evident. In 2016/17, across all age groups, 13.2% were considered insufficient (25(OH)D |
