Food protein-induced enterocolitis syndrome (FPIES) is a non−immunoglobulin E-mediated food allergy with potential risk of malnutrition related to the early onset of disease, frequent avoidance of cow's milk, and the possibility of multiple food triggers. This publication is aimed at providing an evidence-based, practical approach to the dietary management of FPIES. Data Sources: This is a narrative review summarizing information from national and international guidelines, retrospective studies, population studies, review articles, case reports, and case series to evaluate for nutritional risk and develop guidance for risk reduction in children with FPIES. Study Selections: We have included retrospective clinical cohort studies, population-based studies, case reports, and case studies. We did not exclude any studies identified owing to the small number of studies addressing the nutritional management of individuals with FPIES. Results: Children with FPIES are at risk of malnutrition owing to suboptimal oral intake, limited food choices, and knowledge deficits related to feeding. In particular, children with 3 or more FPIES triggers seem to be at increased risk for poor weight gain and developing food aversion. Caregivers of children with FPIES also report a high degree of psychosocial burden.
Key MessagesSuboptimal oral intake, limited food choices, and knowledge deficits related to feeding have contributed to overt malnutrition and malnutrition risk for children with food protein-induced enterocolitis syndrome (FPIES).Children with FPIES to 3 or more foods are at increased risk of developing food aversion and having poor body weight gain.Caregivers of children with FPIES report a high degree of psychosocial burden.Dietary management of FPIES entails avoidance of allergens, supporting normal growth and development and advancement of complementary foods.Providing a detailed individualized feeding plan may help prevent feeding aversions and nutritional deficiencies and ease the burden on caregivers.
