Children with atopic disorders tend to have a higher prevalence of food allergy; about 35 % of children with moderate to severe atopic dermatitis have IgE-mediated food allergy (Eigenann et al. 1998) and about 6 % of children with asthma have food-induced wheezing (Novembre et al. 1988).The National Institute of Allergy and Infectious Disease (NIAID-US) (Boyce et al. 2010) recently concluded that the prevalence of food allergy among all age groups lies between 1–10 % (Hefle et al. 1996; Sampson et al. 2005). Here, IGHE is linked to food allergy.
