<< 3.  While I was a medical student (in the eighties) I was in a clinical
study at the University of Chicago-Pritzker that looked at ethnic differences
in serum vitamin D levels.  The African Americans in the sample studied
(including myself) had stastically significantly lower serum vitamin D levels
than the Anglo counterparts (without showing clinical signs of Rickets).


Guess it is time for me to brush up on my nutrition pathology knowledge and
read the journal article. >>

So, a question would be, are normal levels the same for everyone or are they
different depending on ethnic background or perhaps more likely, geographical
areas of origin? And, do we even have enough of a body of maternal/infant
dyads breastfeeding in a physiologically normal way to look at in evaluating
such questions? I am always leery of what the premise may be for determining
"normal" levels of anything.
