My previous post got me thinking about Melody's recent blood tests one a couple of months ago when it was done the laboratory that carried out the test phoned her doctor because the result was to urgent to wait for the normal reporting procedure it showed her calcium and vitamin D levels to be dangerously low I did not connect it with Type2 diabetes till I just found this.
"
There appears to be a relationship between insufficient vitamin D and calcium status and t2DM. However, the available human data are limited because most observational studies are cross-sectional while prospective studies have not measured 25-OHD concentration and there is a paucity of randomized controlled trials with vitamin D and/or calcium supplementation specifically designed for outcomes related to t2DM. Although the evidence to date suggests that vitamin D and calcium deficiency influences post-prandial glycemia and insulin response while supplementation may be beneficial in optimizing these processes, our understanding of the exact mechanisms by which vitamin D and calcium may promote beta cell function, or ameliorate insulin resistance and systemic inflammation is incomplete. It is also not clear whether the effects are additive or synergistic.
Future research should focus on studies within prospective observational cohorts to clarify and quantify the association between calcium intake and 25-OHD concentration, rather than self-reported intake of vitamin D, and incident t2DM and define the individual contributions of each nutrient on t2DM risk. Additionally, there is a need for randomized trials to examine the effects of vitamin D and/or calcium supplementation with intermediary endpoints (glucose tolerance, insulin secretion, insulin sensitivity) and ultimately with incident t2DM. The results of future studies will define the clinical role of vitamin D and calcium as potential interventions for prevention and management of t2DM, which will have significant public health implications since vitamin D and calcium insufficiency is common in US adults and both interventions can be implemented easily and inexpensively in clinical practice."
