For years, vitamin D has been a rather controversial subject in medicine. While it does bring a considerable number of benefits to the human body, it is also the source of a few problems that humans can have to deal with during their lifetime. Now researchers have found something quite worrying about vitamin D, something that will make you check your levels a few days a week from now on.
There is a possible genetic connection between low vitamin D in our bodies and multiple sclerosis. While medical scientists have had their suspicions about this until now, it was quite difficult to point the finger. But now it is official and this new study, which was published yesterday in PLoS Medicine, has demonstrated how this connection is very real.
There are specific genetic traits that make people vulnerable to multiple sclerosis. Lower vitamin D levels represents only one of these vulnerabilities and it can lead you to a disease that will make your immunity system attack the nervous system.
The hypothesis that low vitamin D is linked to multiple sclerosis has been around for a while, as more and more studies emerged and indicated the link. The only problem was that all previous studies did not exactly show that low vitamin D causes multiple sclerosis. In the best of cases, they would only suggest that it might be possible because of other variables, which made things more ambiguous and other researchers had to restart tests to reconfirm.
To put an end to the question once and for all, the team that conducted the latest study used a secondary analysis, reviewing an earlier study conducted on approximately 35,000 people. All the people had either vitamin D deficiency, or other related issues which were caused by vitamin D deficiency.
It turned out that individuals with any genetic marker related to vitamin D deficiency had a higher chance of developing multiple sclerosis. The study eliminated the possibility of the disease being developed because of any type of lifestyle variable, simply because there was no control over the inheritance or lack of vitamin D deficiency.
So it is official: vitamin D is now known to have an even greater impact on our immunity system than we had thought before and taking care of its levels is of paramount importance. While the study was centered on people who were predisposed to low vitamin D levels, it should also be a warning for us all in order to check our levels and make sure they are always as they should be.
