MADERA, Calif. – As a pediatrician – and as someone who talks with families every day – peanut allergy is one of the most common concerns I hear when parents start thinking about solid foods. For years, families were told to delay peanut introduction. We now know that guidance actually increased allergy risk.
Strong evidence now shows that introducing peanut-containing foods early – around 4 to 6 months of age – can reduce the risk of peanut allergy by more than 80% in many children. That’s a powerful prevention opportunity, and yes, it’s something I routinely recommend for most infants.
The key is how and when peanut is introduced.
Peanut should only be introduced once a baby is developmentally ready for solids – able to sit with support, showing good head and neck control and interested in food. Whole peanuts or thick peanut butter should never be given to infants because of the choking risk. Instead, peanut butter should be thinned with water, breastmilk, formula or mixed into a familiar puree.
For most babies without severe eczema or egg allergy, peanut can safely be introduced at home. Start with a small amount, watch closely for any reaction and continue offering peanut regularly if tolerated. Consistency matters – ongoing exposure helps maintain tolerance.
For infants with severe eczema or known egg allergy, families should talk with their pediatrician first. These babies may benefit from evaluation before peanut introduction, but early introduction is still often recommended – just with guidance.
One important takeaway from recent research is that families do best when they receive clear, simple instructions. Pediatric visits are busy, and parents are navigating a lot of information. Written handouts, step-by-step guidance and reassurance make a real difference in helping families feel confident.
My advice to parents is this:
- Don’t delay peanut out of fear.
- Introduce it safely and in the right form.
- Keep peanut in your child’s diet if tolerated.
- Talk to your pediatrician if you’re unsure or your child has eczema or food allergies.
Preventing food allergies is one of the rare opportunities in pediatrics where small early steps can have lifelong benefits. With the right guidance, early peanut introduction can be both safe and empowering for families.
