This episode of Charting Pediatrics explores the transformative shift in food allergy management from strict avoidance to proactive, personalized care. Dr. Allison Brent is joined by allergists Dr. David Fleischer and Dr. Allison Hicks from Children's Hospital Colorado, who discuss groundbreaking advances including early introduction of allergenic foods, the evolution from early introduction to early intervention, and the growing role of oral immunotherapy (OIT) and biologics like omalizumab. The conversation highlights how early introduction—around 6 months of age—can significantly reduce allergy risk, especially in high-risk infants with eczema. The panel emphasizes the importance of referring patients early to specialists for comprehensive evaluation and treatment, as pediatricians often lack the time and tools to manage complex cases. Emerging therapies, including needle-free epinephrine (Nefi) and a sublingual anaphylaxis film, promise greater accessibility and adherence. OIT and biologics are presented as powerful tools for desensitization and protection, with treatment plans tailored to individual patient needs and family lifestyles. The episode also addresses practical challenges, such as daily dosing, safety protocols, and the critical role of pediatrician-allergist collaboration. Parents are encouraged to be proactive, and the message is clear: food allergies are no longer a life sentence—intervention can lead to long-term tolerance and improved quality of life.
Introduce allergenic foods (peanut, egg, milk, tree nuts, etc.) between 6 months and 3 years of age to reduce allergy risk.
Early intervention with allergists significantly improves outcomes and can lead to long-term tolerance through oral immunotherapy.
Avoid food allergy panels in primary care due to high false positive rates; refer to specialists for accurate diagnosis and management.
Emerging treatments like sublingual anaphylaxis films and quarterly biologics are improving accessibility and adherence.
Biologics like omalizumab can be used to protect against reactions and serve as a bridge to OIT, though they are not disease-modifying.

The Rising Tide of Food Allergies
The episode opens with a vivid clinical scenario of a toddler reacting to peanut butter, setting the stage for a discussion on the emotional and medical burden of food allergies on families and clinicians.
From Avoidance to Early Introduction
“The early introduction really changed things. And I think we did we confused pediatricians years ago when we said 2000 do this. And then a few years later said don't do this right?”
The Window of Opportunity: Early Intervention
“The younger you are there's less anaphylaxis there's more remission rates potential cures”
Practical Guidance for Early Introduction
Clinicians are advised to introduce allergens like peanut, egg, and cow’s milk sources (e.g., yogurt) around 6 months, while respecting family dietary patterns and avoiding medicalization of normal feeding.
Diagnosis and the Perils of Misdiagnosis
“We might end up diagnosing a child with more foods that they're not actually allergic to and then the family's avoiding it and they're very confused.”
“We have five or six treatments in my toolbox, we're going to have huge options for patients. There's not going to be a patient, in my opinion, that can't be on a therapy.”
“It's so thin that it can literally fit in the back of your phone. So there's no excuse ever to not, like a teenager or adult will never have an excuse, in my opinion, to never have epinephrine.”
“The younger you are there's less anaphylaxis there's more remission rates potential cures”
