Many diagnosed with a peanut allergy don't realize they may not have it anymore

Key Points:

• A new study published in the Journal of Allergy and Clinical Immunology: In Practice found that about 35% of infants previously diagnosed with peanut allergies were no longer allergic after undergoing controlled oral food challenges.
• The study involved nearly 800 Australian infants around 13 months old, who were given increasing doses of peanut butter under medical supervision, revealing that many children might outgrow peanut allergies earlier than previously thought.
• Researchers emphasize the importance of re-evaluating peanut allergy diagnoses through supervised food challenges, as this could reduce unnecessary dietary restrictions and improve quality of life for children and families.
• Early introduction of peanuts to infants, now recommended by health authorities, has already led to a significant decrease in peanut allergy incidence, and further retesting could enhance these benefits and reduce healthcare costs.
• Experts caution that food challenges should be conducted in medical settings due to risks like anaphylaxis, but widespread adoption could save money and resources by reducing the number of children labeled with lifelong peanut allergies.
