Low vitamin D levels linked to metabolic syndrome
Increasing blood levels of vitamin D are linked to a lower prevalence of the metabolic syndrome, as well as improved ‘good’ cholesterol levels, says a new study.
According to findings published in the Journal of Clinical Lipidology, the lowest levels of the sunshine vitamin were associated with a 31 per cent prevalence of metabolic syndrome, compared to only 10 per cent for people wit the highest average levels.
The researchers noted that the results do not prove that low vitamin D levels contributes or causes metabolic syndrome, and called for more studies to “assess whether increasing vitamin D intake will improve the metabolic cardiovascular risk factor profile”.
“Although previous surveys have also reported associations between low 25(OH)D concentration and metabolic syndrome components, to our knowledge, the present investigation is the first to report this finding in a sample with a high prevalence of vitamin D dietary supplement users in which frequencies of vitamin D insufficiency and deficiency were low,” wrote the researchers, led by Kevin Maki from Illinois-based Provident Clinical Research
Metabolic syndrome (MetS) is a condition characterised by central obesity, hypertension, and disturbed glucose and insulin metabolism. The syndrome has been linked to increased risks of both type-2 diabetes and cardiovascular disease (CVD).
