What is the purpose of the study?
By 1 year of age, 10% (1 in every 10) of babies will develop a food allergy. Evidence to date suggests that the ideal time to prevent food allergy may be during pregnancy and breastfeeding, but little is known about the effect of what mothers eat during pregnancy and breastfeeding on the risk of food allergies in their babies. This research is testing whether the amount of eggs and peanuts a mother eats during pregnancy and breastfeeding has an influence on her baby’s food allergy development. Study results will be used to develop national recommendations about how much egg and peanut to eat during pregnancy and breastfeeding to reduce egg and peanut allergies in babies.
