What are the benefits of early peanut introduction in infants?

Early peanut introduction in infants has an 80% relative risk reduction in developing a peanut allergy in high-risk infants (Du Toit et al., 2015). Another study showed that early peanut introduction to all infants does no harm. It might even provide benefit to babies without high-risk factors (Perkin et al., 2016).

When should I talk with families about introducing peanuts?

You can start talking about peanut introduction with families when infants are 4 months of age or ready to try solid foods.

What is MGHfC's approach to the new guideline?

A condensed and modified version of the guidelines are below, organized by risk level. Read the full guidelines here.

High-risk infants

  • Severe eczema, egg allergy or both
  • Children with other known IgE-mediated food allergies
    1. Refer your patient to a pediatric allergist for evaluation, possible skin testing and allergy evaluation

- OR -

  1. Send a blood sample for only peanut-specific IgE with reflex components.
  • If the test is positive, order a STAT referral to a pediatric allergist.
  • If the above testing is negative, advise the family to introduce peanut when the infant is 4-6 months of age or ready to try solid food. provide the family with “Introducing Peanut Products to Your Baby,” a handout from the MGHfC Food Allergy Center.

Moderate-risk infants

  • Mild to moderate eczema
  • Other individual or sibling food allergy
  1. Introduce peanuts at home, starting at 6 months of age. Follow the family’s preferences and cultural practices.
  2. Refer the family to an allergist if needed.
  3. Appointments should be scheduled within 3 months of the referral.

Low-risk infants

  • No eczema
  • No individual or sibling food allergy
  1. Provide your patient’s family with “Introducing Peanut Products to Your Baby,” a handout from the MGHfC Food Allergy Center.
