Dietary Intervention in Food Allergy

The goal of this randomized double-blind placebo-controlled clinical study is to determine whether the dietary intervention with pectins leads to food immunomodulation in non-specific lipid transfer proteins (nsLTP) allergic patients. The main question it aims to answer is if the microbiome is a target of intervention against food allergy through the use of prebiotics such as pectins. Participants will be enrolled to receive a two-month dietary intervention with either two different pectins (citrus or apple pectin) or placebo. Increase in oral tolerance to the peach nsLTP will be measured through a double-blind placebo-controlled food challenge (DBPCFC). Microbiome, proteomic and metabolomic studies will also be performed in blood and stool samples.
