Tarah
Thanks for giving us such a tantalizing and good description of this new
study.
Something not mentioned, but which I'm *really* wondering about is how many
of the VLBW babies were *exclusively* fed on human milk, either pasteurized
donor, or their own mothers' milk? Richard Schanler is the ardent
proponent of human milk fortifier, right? He had an article in JHL a few
years ago. And of course we know that human milk fortifier is actually a
cow's milk based additive to human milk to beef it up (pun intended) with
extra calcium, Vit D and other goodies. Since HMF seems to be the standard
of care for VLBW babies in the US, is it likely that the babies in this new
study did *not* receive it?? In other words, were any of them at all
really exclusively breastmilk-fed? If not, could that have helped to
produce the unexpectedness of the results??
