As a child I was always outside in the sun which makes me a bit skeptical of the vitamin D deficiency theory although I now take a supplement just in case. And as far as I know I don't carry the Epstain Barr Virus though I admit to never having been tested for it. Alright, I'm guilty about the smoking, what can I say other then maybe stupidity should be a risk factor as well for MS?
I'm an Epstein Barr-negative non-smoker who has never been vitamin D deficient. I have secondary-progressive MS. This study reminds me of the one done in the early 2000's having to do with high-fat vs. low-fat diets and their connection with MS. There turned out not to be one. There is still no known cause for MS or any plausible "risk factor." The fact that something is "being studied" doesn't make it any more likely than it was before.From everything I have read or heard about MS so far, the two most consistent risk factors for MS are 1) being human and 2) being born.
