Food allergy (FA) can be classified into IgE-and non-IgE-mediated depending on the involvement of IgE in its pathogenesis. In this review, we are focusing on IgE-mediated food allergy. FA affects about 8% of children in the Western countries and seems to be rising in other parts of the world such as in Vietnam and South Africa, and other parts of Asia and Africa, particularly in urban rather than rural areas. [1][2][3][4] The prevalence of FA has increased over the recent decades, as has the number of hospitalizations for food-induced anaphylaxis, following what seems to be the 'second wave of the allergy epidemic' after the rise in the prevalence of asthma and respiratory allergy in previous decades. [5][6][7] Pouessel et al 8 have shown that foods caused 37% of cases of ICU admissions for anaphylaxis and 79% of recurrent anaphylaxis. Self-reported FA is even more common with an often underappreciated impact. 1 Gupta et al 1 report that about 40% of food allergic children report multiple food allergies, often severe food allergies, and carry an adrenaline auto-injector. In Western countries, such as the USA and the UK, FA affects disproportionally children from ethnic minorities, such as children of Afro-Caribbean descent. 1,9,10 Whether this has to do with genetic predisposition in face of environmental factors related to the modern lifestyle
