Early Peanut Introduction linked to Significant Drop in Childhood Allergies
WASHINGTON (October 26, 2023) – A new study suggests that introducing peanuts to infants between four and six months of age may have prevented peanut allergies in approximately 60,000 children in the United States. The research, โpublished recently, indicates a growing adoption ofโค guidelines recommending early allergen introduction, perhaps leadingโฃ to a measurable decrease โin the prevalence of peanut allergy.
Previous recommendations advised delaying peanut introduction, but landmark research immediatly sparked new guidelines urging early introduction – a shift that has seen slower-than-anticipated implementation. Surveys โfound that onlyโ about 29% of pediatricians and 65% of allergistsโค reported following theโข expanded guidance issued in 2017. Confusion and uncertainty about theโฃ best way toโ introduce peanuts early in life contributed to this lag, with initial concerns about replicating clinical settings outside of research environments.
The updated guidance, reinforced in 2021, calls for introducing peanuts and other major food allergens between four and six months, without prior screening โor testing. Parents are advisedโ to consult their pediatricians with any questions.
“It doesn’t have to be a lot of the food, but little tastes of peanut butter, milk-based yogurt, soy-based yogurts and tree butters,”โ explained Dr. Matthew Hill, an author โขof โthe study. “These are โคreally good ways to allow the immune system exposure to these โallergenic foods inโ a safe way.”
Advocates โfor the 33 million Americans with food allergies have welcomed the findings. “This researchโข reinforces what weโฃ already no and underscores aโ meaningful opportunity to reduce the incidence and prevalence of peanut allergy nationwide,” said Sung Poblete, chief executiveโค of Food Allergy โResearch & Education (FARE).
Tiffany Leon, aโฃ Maryland registered โคdietician and director at FARE, introduced peanuts and other allergens early to her own sons, James, 4, and Cameron,โฃ 2. She noted initial skepticism from family members, but emphasized the importance of evidence-based recommendations. “As a dietician, I practice evidence-based โคrecommendations,” Leon said. “So whenโฃ someone told me, ‘Thisโค is how it’sโค done now, these are the new guidelines,’ I just thought, OK, well, this is whatโ we’re going to do.”
While the data โfor the analysis came from a โฃsubset of participating practiceโ sites and may not represent the entire U.S. pediatric population, according to dr. ruchi Gupta, a child allergy expert at Northwestern University, the research offers “promising evidence that early allergen introduction is not only being adopted โฃbut might potentially be making a measurable impact.”
