the latest info I have on this comes from the March 13, 2003 New England Journal of Medicine vol 13 no.11 article "Factors associated with the development of peanut allergy in childhood" by Lack et al
I'm no statistical expert but their study found no association between maternal diet during pregnancy or lactation and peanut allergy
they found that the important associations with development of peanut allergy are:
family history of peanut allergy
early onset of eczema
other rashes with oozing and crusting
use of creams containing peanut oil on broken skin of babies
and the consumption of soy by babies in the first or second year of life (cross sensitisation to peanuts from soy proteins)
this data came from a huge study that identified less than 50 peanut allergic kids from over 12000 births so it's not really a lot of subjects, and other sudies have found different results so it still seems to me that the jury is out over whether or not you should avoid peanuts or maybe all nuts or even soy???? and then what to avoid with babies?
personally I have one nut anaphylactic son - I probably ate some peanuts during pregnancy and breastfeeding but definitely used a cream containing peanut oil
at times on his shocking early onset eczema and other rashes AND he had soy from about 10 months (long story). No family history of nut allergy but lots of other atopic stuff.
with ds2 I never had nuts in the house due to ds1's allergy and certainly ate no peanuts during preg or bf, used no peanut oil creams and he had no eczema or other rashes - he is not allergic to nuts of any kind
how do you make up your mind about this??? like I said, for me the jury is still out
