Earlier ingestion of peanut after changes to infant feeding guidelines: The EarlyNuts study
The Journal of Allergy and Clinical Immunology Sep 23, 2019
Soriano VX, Peters RL, Ponsonby AL, et al. - In view of the findings that timely introduction of peanut to infants attenuates the risk of peanut allergy, and that peanut was consumed by few infants in their first year in a previous study with 5,300 participants, named HealthNuts (2007–2011), as well as considering that introducing peanut before 12 months for all infants was suggested in 2016 update of Australian infant feeding guidelines, researchers performed a population-based, cross-sectional study, the EarlyNuts, to evaluate the results of a nonscreening approach to allergenic food introduction in a population-based sample of infants in their first year of life. Participants were 12-month-old infants in Melbourne, Australia, who were recruited to HealthNuts (72% response rate vs 73% response rate in HealthNuts). Findings revealed a striking shift toward earlier peanut introduction. In 2018 vs 2007-2011, a 3-fold rise in peanut introduction by age 1 year was reported. The presence of possible IgE-mediated reactions in 4.0% of those consuming peanut by 12 months was shown by preliminary results on parent-reported reactions.
