Asthma prevention: Breast is best?

Abstract

Whilst breastfeeding has been considered to exert a preventative effect on the development of allergic disease, several recent publications have challenged this view, particularly with respect to the long-term outcomes for asthma. There are many other beneficial effects of breastfeeding apart from the possibility of allergy prevention. The suggestion that breastfeeding may increase the development of allergic disease raises concerns about the appropriate steps to take for primary prevention of allergy. It is concluded that breastfeeding can still be recommended for the beneficial effects in reducing atopic disease in childhood in addition to the other demonstrated benefits, and that there are unresolved questions concerning the few studies that suggest the possibility of increased allergic disease in later life.
