“…Estimates of average per capita supply of vitamin D, as calculated using information from the FAO national food balance sheets, can be used as proxy measures for vitamin D intake within a population as well as being able to highlight countries where inadequacy of supply may be of concern. A recent global mapping of per capita supply of vitamin D provides estimates for ~170 countries was published [15] and this included those in Central (Meso)-and South America. In general, while much of South America and Meso-America had average per capita vitamin D supply estimates (not including supplemental vitamin D) in the range 1.6 to 5.5 g/d (median of 2.4 g/d), the USA and Canada had estimates in the range 5.6 to 7.5 g/d.…”

“…Data from the same survey shows that the prevalence of vitamin D-containing supplement use was 10%, 6%, 13-18% and 21-25% in children, adolescents, adults (18-50 y) and older adults (51-70 and 71+ y), respectively, and overall within adults, females (24%) had a higher prevalence of usage than males (13%) [77]. The global mapping of per capita supply of vitamin D provides estimates for countries in Oceania beyond the Australia and New Zealand, which are in the range 2.5-7.6 g/d, median of 5.2 g/d [15].…”

“…For infants (0.5-0.9 y), children aged 1-3.9 y, 4.0-6.9 y, and 7.0-12 y, the mean vitamin D intake in urban settings was 5.9, 6.3, 5.5 and 5.5 g/d, respectively, and 7.3, 6.7, 5.7 and 4.6 g/d, respectively, in rural settings. Cognizant of the limitations of the per capita vitamin D supply estimate approach, the global mapping exercise has shown that the median per capita vitamin D supply estimates for all constituent countries within Africa and Asia was 1.4 and 2.8 g/d, respectively, as compared to 4.1 and 4.7 g/d for Europe and Oceania, respectively [15]. There are very few food sources rich in vitamin D. Fish and fish products make up 70% and 78% of the foods codes in the UK's food composition database with vitamin D contents in the range of 5-10 and >10 μg/100 g, respectively [78].…”

“…Fully acknowledging that such standardization was/is not feasible for all such surveys, the review will highlight, but not solely prioritize, such prevalence data. Beyond serum 25(OH)D data, nationally or regionally representative data on vitamin D intake in the population or in population subgroups may provide an additional source of information by which to determine the adequacy of vitamin D status in the population [15]. This narrative review will summarize our understanding of the present situation in relation to vitamin D nutritional status around the globe, based on data for circulating 25(OH)D and vitamin D intake, especially nationally representative data as per the first two priorities mentioned above.…”

“…A review of vitamin D intake as well as status data, from nationally representative samples, where feasible, is particularly novel as the focus of reviews thus far has mainly been on vitamin D status in different world regions. The Food and Agriculture Organisation (FAO) for the purposes of food balance sheet data uses 5 major regions within the World: the Americas, Europe, Oceania, Africa, and Asia [15]. This may be a convenient approach when considering global differences in vitamin D status as well as dietary intake of the vitamin.…”

Background: Internationally, concern has been repeatedly raised about the little notable progress in the collection, analysis and use of population micronutrient status and deficiency data globally. The need for representative status and intake data for vitamin D has been highlighted as a research priority for well over a decade. Aim and methods: A narrative review which aims to provide a summary and assessment of vitamin D nutritional status data globally. It divides the World into the Food and Agriculture Organisation’s (FAO) major regions: the Americas, Europe, Oceania, Africa, and Asia. Emphasis was placed on published data on prevalence of serum 25-hydroxyvitamin D [25(OH)D] <25/30 and <50 nmol/L (reflecting vitamin D deficiency and inadequacy, respectively) as well as vitamin D intake, where possible from nationally representative surveys. Results: Collating data from the limited number of available representative surveys from individual countries might suggest a relatively low overall prevalence of vitamin D deficiency in South America, Oceania and North America, whereas there is more moderate prevalence in Europe and Asia, and possibly Africa. Overall, prevalence of serum 25(OH)D <25/30 and <50 nmol/L ranges from ~5% to 18% and 24% to 49%, respectively, depending on FAO World region. Usual intakes of vitamin D can also vary by FAO World region, but in general, with a few exceptions, there are very high levels of inadequacy of vitamin D intake. Conclusions: While the burden of vitamin D deficiency and inadequacy varies by World regions and not just by UVB availability, the global burden overall translates into enormous numbers of individuals at risk.

Background: Studies have shown the association of vitamin D status with the development of metabolic syndrome (MetS), which has attracted an extensive research interest with inconsistent results. Therefore, we hypothesized that vitamin D supplementation (VDS) will benefit adults with MetS.Aims: To test our hypothesis, we performed a meta-analysis to evaluate the effect of VDS on MetS in adults using relevant biomarkers such as anthropometric parameters, blood pressure, blood lipid profile, glycemia, oxidative stress and vitamin D toxicity (VDT).Methods: Randomized controlled trials published in PubMed, Web of Science, embase and the Cochrane Library between 2012 and 2022 on the effect of VDS on MetS in adults were searched. The language was limited to English. A meta-analysis performed using RevMan 5.4 and Stata 14.0 software, sensitivity analysis, and evaluation of the risk of bias and general quality of the resulting evidence were conducted.Results: Eventually, 13 articles were included in this meta-analysis. Overall, VDS significantly increased the endline serum 25-hydroxyvitamin D levels as compared to the control [MD:17.41, 95% CI (14.09, 20.73), p < 0.00001]. VDS did not affect waist circumference, body mass index, body fat percentage and VDT biomarkers, but decreased waist-to-hip ratio and blood pressure (p < 0.01). VDS significantly decreased fasting plasma glucose (FPG) [MD: 3.78; 95% CI (−6.52, −1.03), p = 0.007], but did not affect the levels of blood high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC), and triglyceride (TG). Pooled estimate of nine papers indicated a significant reduction of fasting insulin (FI) (p = 0.006), and homeostasis model assessment of insulin resistance (p = 0.0001). The quantitative insulin check index levels were moderately increased (p = 0.007) without any impact on the glycosylated hemoglobin type A1C (HbA1c). For the oxidative stress parameters, VDS significantly lowered the levels of malondialdehyde and hypersensitive C-reactive protein (p < 0.05).Conclusion: Results of this meta-analysis demonstrate that VDS only reduces insulin resistance and hypertension but not the blood lipid profile and HbA1c. It appears that the evidence for the benefit of VDS in adults with MetS is inconclusive. Further clinical studies are still needed.
