Early Introduction of Allergenic Foods: A Simple Guide for Parents

Updated: Nov 28

Early introduction of allergenic foods can feel overwhelming when feeding your baby solid foods. Thankfully, new research is making things a bit easier. It turns out that introducing allergenic foods early, instead of later, can help prevent food allergies. Let's go over the basics so you can approach this stage with confidence.

The New Advice on the Early Introduction of Allergenic Foods


In the past, parents were told to wait until after their baby’s first birthday to introduce allergenic foods like peanuts or eggs. But recent studies, like the LEAP (Learning Early About Peanut Allergy) trial, have shown that starting earlier—around 4 to 6 months—can actually reduce the chances of your baby developing allergies. Now, major health organizations like the NIH, USDA, and AAAAI recommend the early introduction of allergenic foods.


When and What Foods to Introduce


Experts now suggest early introduction of allergenic foods when your baby is 4 to 6 months old and ready to start solids. Here’s a list of common allergenic foods to consider:


  1. Eggs

  2. Peanuts

  3. Milk

  4. Fish

  5. Shellfish

  6. Wheat

  7. Soy

  8. Tree nuts


Introduce these foods one at a time, and wait a few days before trying a new one. This way, you can easily spot any allergic reactions. Also, make sure the foods are prepared in a way that's safe for your baby to eat, like smooth peanut butter or well-cooked eggs, to prevent choking.

Keep an Eye Out for Allergic Reactions


When you introduce a new allergenic food, make sure your baby is healthy and you can keep a close eye on them. Watch for any signs of an allergic reaction, which might include:


  1. Hives

  2. Vomiting

  3. Swelling

  4. Coughing or wheezing

  5. Difficulty breathing

  6. Anaphylaxis (a severe, life-threatening reaction)


If you notice any of these signs, get medical help right away.


Special Considerations for High-Risk Babies


If your baby has severe eczema or an existing food allergy, you’ll want to be extra careful when introducing allergenic foods. It’s a good idea to talk to a health provider first, and in some cases, you might need to introduce these foods under medical supervision.
