How To Avoid Peanut Allergies

The worst part of having a severe allergy to peanuts isn’t the high price of EpiPens.

It is that peanut allergies can be deadly, even when you have access to an EpiPen.

And since there is no 100% fool proof way to avoid peanuts and peanut containing foods, doctors have been trying to come up with ways to prevent kids from ever developing peanut allergies.

The first efforts, to avoid peanuts and other high risk foods during pregnancy and early infancy, likely backfired, leading to even more kids with peanut allergies. That’s why recommendations for starting solid foods changed back in 2008, when the American Academy of Pediatrics began to tell parents to no longer delay giving solid foods after age 4 to 6 months and that it wasn’t necessary to delay “the introduction of foods that are considered to be highly allergic, such as fish, eggs, and foods containing peanut protein.”

The latest guidelines are the next evolution of that older advice.

Now, in addition to simply not delaying introducing allergy type foods, as part of a new strategy to prevent peanut allergies, parents of high risk kids are being told to go out of their way to be sure that they actually give their infants peanut-containing foods!

Prevention of Peanut Allergies

Developed by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health, with 25 professional organizations, federal agencies, and patient advocacy groups, these clinical practice guidelines recommend that parents:

  1. introduce peanut-containing foods into your infant’s diet as early as 4 to 6 months of age if they have severe eczema, egg allergy, or both (strongly consider allergy testing first)
  2. introduce peanut-containing foods into your infant’s diet around 6 months of age if they have mild to moderate eczema
  3. introduce peanut-containing foods into your infant’s diet in an age-appropriate manner with other solid foods if your infant has no eczema or any food allergy

Keep in mind that it is possible that your baby already has a peanut allergy, so discuss your plan to introduce peanut-containing foods with your pediatrician first. But don’t be in such a rush that you make peanut-containing foods your baby’s first food. Offer a cereal, veggie, fruit, or meat first. If tolerated, and you know that your baby is ready for solid food, and with your pediatricians okay, then consider moving to peanut-containing foods.

And although not always necessary, it is possible to do allergy testing even on younger infants. Testing is an especially good idea if your infant has severe eczema or an egg allergy. For these higher risk kids, referral to an allergy specialist might even be a good idea, where infants can start peanut containing foods in their office (supervised feeding) or as part of a graded oral challenge. Your pediatrician might also consider supervised feeding for your higher risk child who is not allergic to peanuts.

Peanut-Containing Baby Food Recipes

So how do you give a 4 or 6 month old peanut-containing foods?

It’s not like Gerber has any 1st or 2nd foods with peanuts – at least not yet…

So for now, you can:

  • add 2 to 3 tablespoons of hot water to 2 teaspoons of thinned, smooth peanut butter. Stir until the peanut butter dissolves and is well blended. You can feed it to your baby after it has cooled.
  • mix 2 to 3 tablespoons of a fruit or veggie that your baby is already tolerating in 2 teaspoons of thinned, smooth peanut butter.
  • mix 2 to 3 tablespoons of a fruit or veggie that your baby is already tolerating in 2 teaspoons of peanut flour or peanut butter powder.

Each of these recipes will provide your baby with about 2g of peanut protein. Since the goal is to give your child about 6 to 7g a week, you should offer them three separate times.

During the first feeding, it is important to only “offer your infant a small part of the peanut serving on the tip of the spoon,” and then wait for at least 10 minutes to make sure there are no signs of an allergic reaction, such as hives, face swelling, trouble breathing, or vomiting, etc.

Of course, because of the risk of choking, you should not give infants or toddlers whole peanuts or chunks of peanut butter.
