Skip to content. If you have been told that your breastfed infant has food allergies, you may be wondering what to do next. Will you be able to continue to breastfeed? You may be surprised to learn that in most cases, the answer is yes. Even a baby who has never been formula fed, and has never had any food besides breast milk may show signs of food allergy including: diarrhea, bloody stools, vomiting, colic, eczema, constipation and poor growth. Babies can develop allergies to foods that you are eating while you are breastfeeding.
Proteins in Breastmilk Protect Offspring Against Food Allergy

Research published in the Journal of Experimental Medicine indicates that a mother's diet can protect nursing newborns against food allergies. Conducted by researchers at Boston Children's Hospital and Harvard Medical School, the study offers an explanation for how breastfeeding can promote tolerance to the foods that most often cause allergies. In mice, milk from mothers exposed to egg protein gave protection against egg allergy not only to the mothers' own offspring, but also to fostered newborns whose birth mothers had not received egg. Newborns gained an insignificant degree of protection from mothers who were exposed to egg during pregnancy but did not breastfeed them. The protective effect was strongest when the newborns were born to and nursed by mothers who were exposed to egg before and during pregnancy and breastfeeding.
Proteins in breastmilk protect offspring against food allergy
Yes No. Until recently, there has only been limited evidence to support this suggestion and the authors of a Cochrane review on the subject in concluded that there is currently insufficient evidence to recommend antigen avoidance diets during breastfeeding to reduce the risk of subsequent infant allergies 3. They observed that further research in this area is required and two studies in supported the hypothesis that mothers who eat eggs when breastfeeding may help protect their babies against future egg allergy. The first study 4 , a randomised controlled trial RCT undertaken at the University of Western Australia, investigated how maternal dietary egg ingestion during early breastfeeding influences egg protein ovalbumin levels detected in human breastmilk and whether this influences sensitivity or tolerance to egg protein in the infant. Breastmilk samples were collected at 2, 4 and 6 weeks of lactation for the measurement of ovalbumin.
Most babies have no problems with anything that mom eats. If your baby is sensitive to something you are eating, you will most likely notice other symptoms in addition to fussiness, such as excessive spitting up or vomiting, colic, rash or persistent congestion. Fussiness that is not accompanied by other symptoms and calms with more frequent nursing is probably not food-related. Read more here about normal baby fussiness.
