Vitamin D Deficiency Linked to Inflammatory Bowel Disease, Mortality in Prostate Cancer, and Type I Diabetes

Well, if you're a Canadian reading this, I hope you got out to vote yesterday for the federal election. Doesn't matter what party, as long as you voted. You can't continue to complain about our government if you're not going to do your small piece to bring about some change.

So on to the topic(s) at hand...I've got three new studies on vitamin D deficiency. First, this new study didn't actually found anything "new," but I'll cover it here since it is a weird coincidence that this study was published about the same time as the vitamin K study in my previous post.

Since vitamin D deficiency is common in inflammatory bowel disease (IBD), authors of this study set out to find if vitamin D deficiency is associated with increased disease activity and lower health-related quality of life (HRQOL).

I'll cut to the chase here -- since, like I said, nothing new here. The researchers found that vitamin D deficiency is common in IBD and is independently associated with lower HRQOL and greater disease activity in Crohn's Disease.

For prostate cancer, a new study showed that those with the lowest amount of vitamin D had a 22% greater risk of death from the cancer (compared to prostate cancer patients with the highest vitamin D levels), and suggested increasing plasma concentrations of vitamin D may lead to better disease outlook for men with prostate cancer.

Lastly, in a prospective, observational, follow-up study involving 227 patients with type 1 diabetes mellitus who were followed from the onset of diabetes, severe vitamin D deficiency was found to be a significant independent predictor of all-cause mortality (death). The next step the researchers suggest is to determine whether supplementation with vitamin D can improve the prognosis of these diabetics.

The conclusion? If it's not obvious... make sure you're getting enough vitamin D. (FYI, the D3 form is ideal for humans, not D2.)
