Child Allergy

In last decades, a change in dietary habits has been observed in industrialized countries characterized by a drastic increase in the consumption of ultra-processed foods (UPF, Ultra-Processed Foods). As defined by the NOVA classification, UPFs are industrial formulations of food substances added with colourings, flavourings, emulsifiers, thickeners and other additives. Among the main compounds of UPFs are the advanced glycation end-products (AGEs). Increasing evidence suggests an association between dietary exposure to AGEs and the development of chronic non-communicable diseases, such as obesity and allergies, in the general population, through increased oxidative stress and inflammation. Preliminary evidence suggests that a maternal diet rich in AGEs during pregnancy and lactation could negatively influence the composition of breast milk and have a negative impact on the infants health. However, data regarding the presence of derivatives of UPFs in breast milk are not available. The UFIM (Ultraprocessed Foods In Breast Milk) study aims at evaluate the presence of UPFs-derivatives compounds in breast milk.

The goal of this study is to set up a paediatric observatory within the allergology department of The saint Vincent Hospital, Lille. The study aims to: • Collect exhaustive prospective data from patients eligible for oral immunotherapy. This prospective observatory will enable statistical analyses to be carried out on common food allergens such as hazelnut, cashew nut, pistachio and others.

In this study, a birth cohort was established to demonstrate the causal relationship between allergies and neurodevelopment disorders in infants and young children, and to find out the influencing factors of neurodevelopment disorders in early life.
