Judy,  
 
This is an excellent review of IgE mediated food allergy and treatment .  
Thank you.
 
  When I read the Medscape article you cited, it triggered  a  memory of 
reading something else with regards to allergy and  breastfeeding.  When I looked, 
I found it was another  Medscape  article I read recently.
 It was posted in September of 2007.   
_http://www.medscape.com/viewarticle/562893_ (http://www.medscape.com/viewarticle/562893)    That one said that it 
was uncertain if breastfeeding reduced allergy  risk.  It talked about newer 
findings. 
 
Interestingly,  I got this as a notice today from Pubmed which reviews  risk 
factors and talks of a new hypothesis:

This article reviews possible risk factors and  theories for the development 
of food allergy. It is noted that previous  strategies to prevent food allergy 
through allergen avoidance during pregnancy,  breast-feeding, and infancy 
have more recently been called into question.  Alternative hypotheses are 
examined with respect to food allergy, namely the  hygiene hypothesis, the dietary 
fat hypothesis, the antioxidant hypothesis, and  the vitamin D hypotheses. An 
alternative hypothesis is proposed, suggesting that  sensitization to allergen 
occurs through environmental exposure to allergen  through the skin and that 
consumption of food allergen induces oral tolerance.  This hypothesis provides a 
possible explanation for the close link between  eczema and the development 
of food allergies. It also suggests novel  interventional strategies to prevent 
the development of food  allergies.
