Study Finds Mixed Associations Between Breastfeeding and Childhood Allergies
-Six months of exclusive breastfeeding was associated with a higher prevalence of food allergy and atopic dermatitis-
Summary
To examine the impact of breastfeeding on food allergy, researchers at the University of Toyama analyzed data from more than 88,000 children followed from birth to 6 years of age. They compared childhood allergies among those who were exclusively breastfed, partly breastfed, or formula-fed during their first 6 months. They found that exclusive breastfeeding was associated with lower prevalence of bronchial asthma and allergic rhinoconjunctivitis but higher prevalence of food allergy and atopic dermatitis.
