  • Title: Fatty acid deficiency profile in children with food allergy managed with elimination diets.
    Author: Aldámiz-Echevarría L, Bilbao A, Andrade F, Elorz J, Prieto JA, Rodríguez-Soriano J.
    Journal: Acta Paediatr; 2008 Nov; 97(11):1572-6. PubMed ID: 18671692.
    Abstract:
    AIM: To evaluate plasma fatty acid (FA) composition of children with food allergy undergoing elimination diets that avoided the offending antigens. METHODS: Twenty-five children (14 male, 11 female) aged 3.8 +/- 1.6 years (range 2-7 years) affected of multiple food allergy and managed with elimination diets participated in a cross-sectional study. Results of plasma fatty acids were compared with data obtained in 61 healthy children. RESULTS: The patients had significantly lower values for plasma content in total polyunsaturated fatty acids, omega3 polyunsaturated fatty acids and long-chain omega3 polyunsaturated fatty acids (p < 0.001) and particularly, in eicosapentaenoic acid (EPA) (20:5omega3) and docosahexaenoic acid (DHA) (22:6omega3) (p < 0.001). Moreover, all established indices (essential fatty acid [EFA] index ((omega3 +omega6)/(omega7 +omega9)) (p < 0.001) and sufficiency of docosahexaenoic acid index (C22:6omega3/C22:5omega6) (p < 0.001)) confirmed the presence of EFA deficiency. CONCLUSION: Children with food allergy managed with restricted intake of foods such as milk, egg, fish and vegetables are at risk of developing a deficiency in EFA and particularly in omega3 long-chain polyunsaturated fatty acids, which are especially necessary for adequate growth, neurological development and cardiovascular health.
