## New study on peanut allergies
A study published Wednesday found 35% of babies diagnosed with peanut allergy outgrow it by oral food challenges.
## Previous understanding of peanut allergies
It was thought between 10% and 20% of children with peanut allergy eventually lose the diagnosis.
## Study methodology
The study tested 1,275 babies under 18 months with peanut allergy diagnoses using medical supervision.
## Oral food challenge results
Of 778 babies given increasing peanut amounts, 65% had reactions and 12% had potentially life-threatening reactions.
## Study lead
Tim Brettig, a pediatric allergist and immunologist who helped lead the study, said they didn't expect this many children to pass food challenges.
## NIH guidelines
NIH now advises freely introducing peanuts to infants with no eczema or food allergies.
## FARE recommendations
FARE recommends delaying peanut introduction until age 3 to prevent allergies, but has since rescinded those guidelines.
## Study implications
The findings support increased use of food challenges in allergy assessment and retesting children diagnosed with peanut allergy.
## Philadelphia hospital
The Children's Hospital of Philadelphia offers information about peanut allergy and treatment on its website.
## Key takeaway

A study finds 35% of babies diagnosed with peanut allergy outgrow it by oral food challenges.
