Yrjana JMS, et al. - Among preterm infants, if the early introduction of semisolid foods impacts the prevalence of food allergy or atopic dermatitis was determined by analyzing retrospective data from 464 preterm infants born in Oulu University Hospital between 2008 and 2012. They noted that the incidence of food allergies or atopic dermatitis did not increase following very early introduction of complementary foods into the diet of preterm babies. This finding was true even among the most preterm infants, and provided support to the presumption that the gut-associated lymphoid tissue of preterm infants is ready to encounter food proteins and to begin the maturation process within 3-6 months of birth, regardless of the gestational age.
