As I am now the mom of a baby with a suspected walnut allergy can longterm breastfeeding help decrease the risk for other nut and peanut allergies?
I did some research on this and all that I found was that exclusive breastfeeding (not even one feeding of formula) for the first 4 months of baby’s life can decrease the risk of asthma and atopy. (http://ajph.aphapublications.org/cgi/content/abstract/94/9/1531)  I did not find anything credible on breastfeeding over 1 year and the effects on decreasing allergies.
