Hi Joan,
Thanks for the information and the link. I did some reading after your
email arrived. Variations of BCM in human milk are also thought to
reflect food allergies in mothers.
There are some alternative explanation for these data that come
immediately to mind, but I'll do some reading and try to "catch up" in
this area.
On a practical level, I'm not aware of casein powders that declare the
breed of cattle from which the casein was extracted. Thus, if we can't
distinguish the source of the milk what difference does it make whether
some milk might not cause the problems I outlined?
Best Wishes,
Ron
