Interesting article. I had a doctor once tell me that since I have MS my body has a harder time processing vitamin D. I don't know how true that is or not. My vitamin D was low and I was given a prescription for it. I also made sure I got plenty of sun time in the spring/summer. So far, things have been going well and I haven't had a problem since.

And, growing up, I was outside all the time (with the exception of days when it was raining or snowing). So, I'm not 100% sure about the whole vitamin D theory. I do believe it is a factor but I also think that more people would have MS. If I look at my immediate family (10 kids), we all grew up together in the same places, had the same diet, were all active and outside all the time, etc. and I'm the only one with MS. If sunlight was a big factor, I would think one of my siblings would have MS as well. Take that further in to my extended family, I'm still the only one with MS despite the fact of where we lived and sunlight. Again, if sunlight was a factor, you would think one of my cousins would have MS. As far as we know, no one other than myself has MS (this includes my grandparents, great grandparents, etc.) all of whom lived north of Atlanta.
