It is not that Africans cannot make VitD, in tropical latitudes with high levels of sunlight exposure dark skin provides perfectly adequate amounts of VitD. It is only when Africans move to higher or lower latitudes that the levels of UV light exposure, especially in the winter, are insufficient. Europeans have no such problem, their light skins enabling them to make enough VitD at those latitudes, if they expose enough of it.

Not being able to find much data on a problem can be indicative of there not being a problem to provide data for. This should always be considered before embarking on a research project. IOW for good reasons VitD plays no significant role in HIV infection.

Lines that curve over like that in the right situation are diagnostic of a saturation effect whether in Chemistry, Biochemstry or many other situations.

When I was in Kenya (2004-2006), it was obvious that folks were falling like flies from HIV/AIDS, tuberculosis, malaria, malnutrition etc etc etc. When I got back to America, I entered the journal reading stream again and came across the hype for Vitamin D and its miracles. All things in perspective… However, when I began to learn that Africans cannot make Vitamin D. When I read that Vitamin D is valuable for building an immune response. When I realized that the people I had dealt with had ___?? Vitamin D levels. When I read more about the effect of Vitamin D on management of tuberculosis. I began to ask if Vitamin D had anything to do with assistance or detriment in building an immuune rsponse in tuberculosis, HIV/AIDS, and other such stuff.

I asked our regional search library to look and I have not found very much. I communicated with a fellow from the Netherlands and one from Berkeley but that was about it. My sense was that they thought it was interesting but didn’t know a lot.

Of course I’d love to do a study of Vitamin D levels at the equator, the prevalence of HIV/AIDS, the managements, and whether anybody is alive at the end of any management with Vitamin D.

I would be very interested in your take on this. Bill Gates keeps challenging folks to present some “novel” ideas. I don’t want to be stupid, but I do wonder.

I just can’t seem to find much data. I realize that may not be your favorite area, but I do keep looking.

Your thoughts on this welcomed.
