"A new study in mice shows that exposure to an allergen through breast milk can actively program a pup's immune system to prevent asthma later in life. Exposure to both the allergen and a specific immune factor passed on through the milk by the mother was necessary for protection. This study suggests that a mom's exposure to allergens during breastfeeding can help protect her baby from reacting to those allergens later in life."
