Peanut

Studies in people

• Benefit

  Early feeding protection²

  In infants, eating peanut protein early cuts peanut allergy by about 80%, but waiting makes it work less well.

• Concern

  allergy reaction risk³

  In people with peanut allergy, peanut oral immunotherapy raises the risk of severe allergic reactions compared with avoiding peanuts.

• Open question

  allergy relief options⁴

  Scientists are testing ways to help people with peanut allergy, but no treatment works perfectly for everyone.

• Benefit

  Infant feeding and allergy⁵

  Feeding peanut to babies at high risk cut peanut allergy later, compared with avoiding peanut.

• Concern

  Reaction severity markers⁶

  In people with peanut allergy, antibodies against Ara h 2 and Ara h 6 tracked with how severe their reactions were.

• Open question

  Patch desensitization results⁷

  A peanut patch helped toddlers with peanut allergy tolerate more peanut, though some had allergic reactions.

• Benefit

  Oral treatment for food allergy⁸

  In 1- to 4-year-olds with peanut allergy, peanut SLIT helped more children tolerate peanut.

Study type not stated

• Concern

  allergenic seed proteins⁹

• Concern

  lifelong food allergy management¹⁰

  Peanut allergy often lasts a lifetime, so people manage it by avoiding peanuts and keeping emergency medicine.

The signal at the top counts the findings in people and in animal and lab studies. A concern in studies of people outranks animal and lab studies, and “No concerns” needs at least two findings in people. Findings whose study type is not stated are shown but not counted.
