Prevent Peanut Allergies
Did you know that up to 86% of peanut allergies can be prevented? But this can only happen if every new parent knows about and introduces peanut foods early to their infant. Whether you are a new mom, peanut farmer, food allergy advocate, healthcare provider or WIC professional, your voice can help make early introduction the standard of care and standard practice. Educate yourself with the resources on this site and speak out to give all families an equitable chance to prevent peanut allergy.
Change Your Child’s Future
Imagine not having to worry your child will develop an allergy to peanuts – and the lifetime of anxiety and fear that come with it. Fortunately, food allergy experts and others who care for children now agree that feeding small amounts of peanut foods to infants at the right stage of their development – typically around 4-6 months of age – can have life-changing effects. If your child has severe eczema and/or egg allergy, talk with your child’s doctor or nurse about when and how to safely introduce peanut foods.
Evidence continues to build about allergy prevention.
These recommendations are rooted in the groundbreaking LEAP (Learning Early About Peanut) Study, in which early introduction reduced development of a peanut allergy by up to 86%. Today, guidelines from the National Institutes of Allergy and Infectious Diseases are endorsed by the American Academy of Pediatricians and championed by healthcare providers everywhere. And evidence continues to grow. In fact, the Dietary Guidelines for Americans, 2020-25 also encourage early introduction of peanuts and other foods.
It’s that important. And we have your back.
As a parent of a newborn, you already have a lot on your plate. But delaying peanut foods – even just a few weeks or months – can miss the window. That’s why the National Peanut Board and partners have assembled these tips, resources and answers to common questions to help you have the knowledge and confidence to act.

What are the new guidelines?
New guidelines encourage parents to introduce baby-friendly peanut foods depending on each child’s risk for allergies. Peanut foods should be introduced according to these guidelines after they’ve already started other solid foods.
- If your infant has severe eczema, egg allergy, or both, the new guidelines recommend talking with your doctor before giving them any peanut foods. Your healthcare provider might want to do an allergy test or introduce baby-friendly peanut foods under medical supervision. Once cleared, infants in this category should start eating peanut foods around 4–6 months of age and should continue to consume them regularly – 2g of peanut protein, three times per week.
- If your infant has mild to moderate eczema, the new guidelines recommend feeding them small amounts of baby-friendly peanut foods, like peanut powder or thinned peanut butter, around three times a week starting when they are around 6 months old.
- If your infant has no eczema or any food allergy, the new guidelines recommend introducing foods that contain peanuts together with other solid foods as often as you would like and in accordance with family preferences and cultural practices after 6 months of age. Most children will fall into the low risk category.
What research are these recommendations based on?
The recommendations to introduce peanut foods early are largely based on a recent study called Learning Early about Peanut Allergy (LEAP), released in early 2015. This study found that eating peanut foods early could prevent peanut allergy in high risk infants.A second study, LEAP-On, found that if high-risk children ate peanut foods regularly until 5 years of age, there was no increased risk of developing peanut allergy during their 6th year of life even if they avoided peanuts for one year.
Why did the guidelines for introducing peanut foods change?
The groundbreaking LEAP Study found parents of children at risk for peanut allergy could reduce their baby’s chance of developing a peanut allergy by up to 86 percent by feeding them small amounts of peanut foods as early as 4-6 months of age. It led to guidelines by the National Institutes of Allergies and Infectious Disease (NIAID), the American Academy of Pediatrics and other medical groups.
Will these recommendations prevent all babies from developing peanut allergy?
No, these recommendations will not prevent all babies from developing peanut allergy. However, according to the LEAP study, parents of children at risk for peanut allergy could reduce their baby’s chance of developing a peanut allergy by up to 86 percent by feeding them small amounts of peanut foods as early as 4-6 months of age.
Do the recommendations apply to other foods?
The Dietary Guidelines for Americans (2020-25) give priority to peanut and egg, but evidence supports introducing all potential allergens in the first year.
Should I speak to a pediatrician or family doctor before introducing peanut foods?
No, these recommendations will not prevent all babies from developing peanut allergy. However, according to the LEAP study, parents of children at risk for peanut allergy could reduce their baby’s chance of developing a peanut allergy by up to 86 percent by feeding them small amounts of peanut foods as early as 4-6 months of age.
If my baby is older than the recommended age to introduce peanut, what should I do?
If your baby does not have severe eczema or egg allergy, peanut can be introduced into their diet when you introduce other solid foods, as long as it’s in an age-appropriate way (to avoid choking risk). If you have concerns about introducing peanut foods into your baby’s diet, consult your pediatrician. Finally, if your child has egg allergy or severe eczema, they should be seen by a physician before peanut foods are introduced into their diet.
How much and how often should peanut foods be fed to the infant?
Once peanut foods are introduced into the diet and tolerated, they should be kept in the diet on a regular basis – 2g of peanut protein, three times per week – in order to maintain a tolerance to peanut protein. See our “How to Introduce” page for easy ways to introduce.
What do I do if my baby has a reaction? What do I look for?
Allergy symptoms usually develop within minutes of eating a food, but can occur up to 2 hours after ingestion. Allergy signs and symptoms can be mild, such as a new rash or a few hives around the mouth. More severe symptoms can include swelling of the lip, eyes, or face, vomiting, widespread hives on the body, breathing symptoms such as repetitive cough, wheeze, or any difficulty breathing, a change in skin color (pale, blue), or sudden tiredness/lethargy/seeming limp. If there are any concerns for more severe allergy symptoms, seek immediate medical attention/call 911.
