Something I have been thinking about is the reliability of the studies that
look at contamination of breastmilk with fat soluble toxins. I actually was
thinking about this in my sleep and woke up with the revelation that the
researchers would have to be very knowledgeable about breastfeeding and
breastmilk to ge a half reasonable estimation of the contamination levels
in breastmilk. I was thinking about the work that Peter Hartmann has done
on how fat concentration in breastmilk changes throughout a feed and
throughout a day. I haven't got any studies in from of me at the moment but
I wonder how the researchers have tackled this variation because obviously
variation in fat concentration means variation in toxins in fat. How many
studies do you think have been done with just a random sample of breastmilk
taken?
I'll have to go on a hunt and find out.
