Once an allergy is confirmed, strict egg avoidance in the diet is recommended. Otherwise, there is currently little evidence to support particular dietary interventions for the prevention or management of egg allergy. However, there is evidence regarding cow’s milk allergy that suggests irregular ingestion in early life may promote allergy, supporting the idea that once a potentially allergenic food is successfully introduced into the diet it should be consumed regularly (a few times weekly) to prevent loss of tolerance.[1] For short- or long-term formula-fed infants, replacing regular cow’s milk or soy formula with a formula that is partially or extensively hydrolyzed (proteins are broken down into smaller pieces) is likely not effective for preventing food allergies.[2][3] Similarly, while breastfeeding is associated with a multitude of health benefits for the infant, it has not consistently been found to help prevent food allergies.[4]
