In response to Cheryl Taylor White's posting *********************** > >One of the things that interests me is that not all women transmit cow's > milk proteins through their milk. Where is this information taken from? I'd like to read more. It is contradictory to what I've seen. *********************** I dug through my wad of colic and breastfeeding articles and came up with this one. Sorva J et atl, 1994. Beta-lactoglobulin secreion in human milk varies widely after cow's milk ingestion in mothers if infants with cow's milk allergy. J. Clin Immunol 19(4):787-92. They looked at mothers of infants with and without cow's milk allergies and after an oral cow's milk load 6 of 39 mothers of infants with cow's milk allergies and 4 of 8 mothers of infants without cow's milk allergies had undetectable levels of beta-lactoglobulin after an oral cow's milk load. I think I may have more, but dont' have a lot of time to go searching right now. There's another interesting abstract, for which I'd like to read the whole article that makes an interesting comment that "Milk from mothers consuming cow's milk proteins contains small amounts of beta-lactoglobulin, in the majority of infants both atopic and nonatopic TOLERANCE rather than SENSITIZATION. *********** I find this area of research is so complex and so confusing. The biggest obstacle to understanding the implications for breastfeeding is that the articles often lump formula-fed infants and breastfed infants together as if the process were the same! Hope this is helpful.
