I will be presenting a talk in about a month on the long-term effects of human milk on the recipient infant's immune system, and how changes in the mother's age, parity, immune or nutrition status can modify these effects. While I surely have plenty of material to fill my 30 minute time slot, I would like to tap the wonderful resource that Lactnet is for other viewpoints while I have time to modify my talk. Judging from past experience with this group, some of you scour the literature with the avarice of bloodhounds looking for articles on the benefits of human milk (an admirable task IMHO). If you have come across articles showing changes in the immune system (cancer risk, allergies, vaccine responses, etc. would be included) among adults who were breastfed as children, I would love to hear about them by private E-mail. Also, if you have seen any papers on the immunological composition of milk from adolescents vs. adults, I would be very interested in hearing about them. After the conference, I will see about posting to Lactnet a summary of the information I presented. Thanks in advance. ----------- J.
