This month she answers your questions about food allergy and breastfeeding.


Is there a recommendation for breastfeeding and food allergy?

  • If an infant is diagnosed with a food allergy, should a breastfeeding mother avoid that allergen in her diet?
  • If an infant is showing early signs of dairy intolerance like eczema, should a breastfeeding mother cut out dairy from her diet?

Most breastfeeding mothers can eat what they like, and it is rare for babies to have symptoms from foods in breast milk. Routine avoidance of foods from the maternal diet is not recommended. A maternal elimination diet is recommended with certain allergic conditions, such as when an exclusively breastfed baby has FPIES or a similar condition. It is not typically recommended to use a maternal elimination diet for infant eczema.

If an elimination diet is considered, it should be done with medical supervision to ensure the symptoms are treated with elimination and for the benefits of the special nutritional requirements during breastfeeding.


Thank you, Dr. Upton, for your insightful and helpful answers!
