I don't think we've discussed the latitude/cholesterol/vitamin D
connection much. It's interesting, although it makes me wonder about
whether serum cholesterol levels correlate well with cholesterol in the
skin for conversion to D. I do know that there's a lot of very
interesting information about vitamin D and how many of us are
deficient. For example,
http://www.newmediaexplorer.org/chris/2006/12/17/statins_and_vitamin_d_deficiency_another_blow.htm.
This article mentions the connection between certain autoimmune
diseases, such as RA and MS, and D deficiency. It has been known for a
while that the incidence of MS goes up at higher latitudes. I don't
know if this is true of RA.
