Primary prevention of food allergy in 2021: Update and proposals of French-speaking pediatric allergists

D Sabouraud-Leclerc et al. Arch Pediatr. 2022 Feb.

Abstract

During the past years, there has been an alarming increase in cases of food allergy and anaphylaxis in ever-younger children. Often, these children have multiple food allergies and food sensitizations, involving allergens with high anaphylactic potential, such as peanuts and nuts, which have a major influence on their quality of life and future. After reviewing the current epidemiological data, we discuss the main causes of the increase in food allergies. We analyze data from studies on the skin barrier and its fundamental role in the development of sensitization and food allergies, data on the tolerogenic digestive tract applied in particular to hen eggs and peanuts, as well as data on the prevention of allergy to cow milk proteins. In light of these studies, we propose a practical guide of recommendations focused on infants and the introduction of cow milk, the management of eczema, and early and broad dietary diversification including high-risk food allergens, such as peanut and nuts while taking into account the food consumption habits of the family.

Keywords: Anaphylaxis; Atopic dermatitis; Cashew; Egg, Peanut; Food allergy primary prevention; Food diversification; Hazelnut.
