Pediatric Allergy - What We Learned in 2021

December 14, 2021 2 min read

This year brought about some revolutionary data in pediatric allergy. SpoonfulONE's Medical Team has summarized the most interesting research to emerge:

  1. Diet Diversity is Critical: Data continues to demonstrate increased diet diversity in early childhood is inversely associated with atopic diseases. The PASTURE study group published new research showing inverse associations between food diversity in early childhood and allergic diseases, reinforcing data from Venter et al. in 2020.
  2. Choose Skin Emollients Carefully: Additional data analyzed from the EAT study by Perkins et al. suggest that regular application of moisturizers to the skin of infants may lead to developing food allergies through either transcutaneous sensitization or moisturizers potentially damaging the skin barrier. Early data suggests using trilipid-based emollients over petrolatum-based emollients for infants may avoid such risks.
  3. What We Eat Impacts Our MicrobiomeData continues to unfold demonstrating the important impact diet and nutrition has on the gut microbiome, which may play a role in food allergies, along with environmental factors. 
  4. Consensus Guidelines Clarify Food Allergy Prevention Recommendations: The North American Allergy Societies (AAAAI/ACAAI/CSACI) have put out crisp and clear guidance on the recommendations for introducing and feeding common allergens to infants. Read about the new guidelines here
  5. Guidelines Still Not Reaching Parents: In a survey of pediatricians around the US about the adoption of the Early Peanut Introduction Guidelines, most pediatricians (68%) expressed the need for more education/training and materials to provide parents with the early introduction recommendations.
