The role of nutrition in preventing atopic diseases including atopic dermatitis has recently gained interest in the medical community. Caregivers of infants and children at an increased risk for developing atopic dermatitis often employ exclusion diets or other measures in hopes of preventing the development of this burdensome disease. This paper reviews the current literature in regard to the role of preventative dietary measures in the context of atopic dermatitis, with a special focus on the topics of hydrolysed formula, early vs. delayed introduction of certain foods and fatty acid supplementation. Literature pertaining to preventative dietary measures for infants at risk for atopic dermatitis was reviewed. Analysis of the literature suggests that hydrolysed formula should not be routinely offered to infants for prevention of atopic dermatitis. Formulas utilised should contain concentrations of polyunsaturated fatty acids similar to that in breast milk. Finally, infant caregivers should not delay or restrict introduction of food, which can be more harmful than helpful to the patient. Recommendations to caretakers providing for infants at risk for atopic dermatitis should include infant consumption of breast milk and avoid delayed introduction of foods. ©2020 Foundation Acta Paediatrica.
