Interesting and concerning, Rachel....a google on those researchers
names shows previous discussions and papers on VitB12 and
breastfeeding. Vitamin B12 is (I learn) also described as cobalamin.
I found this account of a PhD thesis (from next-door-to-Norway Denmark):
http://sciencenordic.com/exclusive-breastfeeding-may-cause-b12-deficiency-babies
"Immediately after birth, the B12 levels in the breast milk are high,
but four months after birth the levels have dropped dramatically. And
when we look at the babies after four months, we see that their B12
levels are so low that we can conclude that they're not getting
sufficient amounts of B12," says the researcher.
Now.....*why* do the levels drop? Is there a physiological reason?
How could we be sure that a physiological drop might mean 'they're
not getting sufficient'?
This reminds me of the trope that 'breastmilk is low in iron'.
