Evaluation of the introduction of allergen-containing foods Feeding Infants and Toddlers Study 2016

Background: Guidelines on the early introduction of allergen-containing foods are evolving; however, little national data exist defining current allergen-feeding practices. Objective: To investigate the consumption rates of foods containing egg and peanut among infants and toddlers before the guideline changes in 2017. Methods: The Feeding Infants and Toddlers Study 2016 was conducted nationally among 3235 caregivers with a child under 4 years of age. The 24-hour dietary recalls were reviewed for peanut or egg ingredients. Participants were categorized as consuming peanut or egg-containing foods or not consuming peanut or egg-containing foods. Data on physician-diagnosed food allergies and avoidance were collected. Results: The consumption rates of peanut-and egg-containing foods were low. For the age group of 4 to 5.9 months, 0.3% reported peanut consumption and 2.4% reported egg consumption. For the age group of 6 to 8.9 months, 0.9% reported eating peanut-containing foods and 13.0% egg, and for the age group of 9 to 11.9 months, 5.5% were consuming peanut-containing foods and 33.2% egg-containing foods. Peanut or egg ingredients were identified in the diet of children whose caregivers reported avoidance. Conclusion: Before the publication of the 2017 Addendum Guidelines for the Prevention of Peanut Allergy, there were low rates of reported peanut consumption across the study population with less than 1% of any age group before 9 months of age and less than 6% in any age group before 12 months of age consuming peanut on the 24-hour recall day. In addition, reported egg consumption was low and increased with age. These results serve as an important baseline comparison for future studies evaluating the implementation and impact of early peanut and egg introduction.
