Food Allergies And Breastfeeding: Is There A Link?

July 16, 2021 3 min read

food allergies and breastfeeding, is there a link?

Breastmilk has long been known to provide a wealth of benefits to babies, from complete nutrition to a wonderful bonding experience.

But does it affect the risk of your baby developing food allergies?

There are many factors that come into play when evaluating a baby’s risk of developing allergies - including genetics, maternal diet, and food introduction. When it comes to breast milk, research provides inconclusive evidence that breastfeeding alone can help prevent food allergies, though it does play a role in strengthening the immune system.

Here’s what parents need to know about breastfeeding and allergies!

Breastmilk Has Protective Antibodies

There are five antibodies in breast milkthat are essential in helping the body stay healthy. These antibodies (immunoglobulins) can provide many great benefits for growing babies, including helping to fight off germs, illness, and disease.

Not only will these immune-boosting substances continue to protect your child for as long as they breastfeed, but in the years after as well

Benefits of Breastfeeding

  • It is formulated for your baby’s needs, with the ideal amount of vitamins, proteins, fats, and other nutrients to provide for their nutritional and developmental needs.
  • Contains antibodies that help protect your baby against illness and help the body stay healthy.
  • Provides beneficial bacteria, enzymes, and prebiotics to protect your baby’s digestive system, immune system, and promote a healthy gut.
  • It may lower the risk of sudden infant death syndrome in the first year of your baby's life.
  • Long-chain fatty acids help develop your baby’s brain, nervous system, and eyes.

Can My Child Get An Allergy Through Breastmilk?

Babies get necessary nutrients, vitamins, and fats from breast milk as well as food proteins from the foods the mother is consuming. If mothers consume allergenic foods while breastfeeding, their baby may gain some level of exposure to allergens

For concerned parents, there is no evidence of an increased risk of allergies developing when consuming allergenic foods while breastfeeding. 

Recent research has shown no association between maternal exclusion diets and the prevention of allergies. The latest guidelines from allergy researchers do not recommend that mothers avoid common allergens in their diet during pregnancy and lactation as a means to prevent food allergy. 

Can Breastfeeding Prevent A Food Allergy?

Breastfeeding will not alone prevent food allergies in babies, unfortunately. If you look at data between breastfed versus formula-fed babies, there is no direct benefit for food allergy prevention afforded by breastfeeding your baby.

However, eczema is the number one risk for a baby to develop a food allergy and we do know that breastfeeding has been found to protect against eczema in the first 3 months of life. Therefore, breastfeeding can reduce some risk factors and can contribute to improving your baby's tolerance.

Early Allergen Introduction

While breastmilk provides amazing immune system benefits, early allergen introduction is essential to help ensure your baby gets the best head start when it comes to allergies. 

According to landmark studies like EAT and LEAP, early and sustained introduction of allergenic foods should begin at the critical window of 4-6 months. 

During this time, the baby’s immune system starts to develop positive or negative responses to food proteins introduced to their diet. 

At SpoonfulONE, we make early food allergy introduction as easy as possible, including the 16 food groups responsible for 90% of food allergies in an easy-to-use format. 


The bottom line: There is no connection between breastmilk and an increased risk of developing allergies. In fact, breastfeeding for the first four to six months helps strengthen the immune system.
