Breast milk can help protect against asthma
Researchers in France have discovered for the first time the mechanisms that explain the protection breastfeeding offers against infantile asthma. Through this study, which was carried out on mice, they were able to establish that exposure to a respiratory allergen in breast milk reduces allergic response by more than 60%!
The researchers exposed suckling mice to airborne allergens using aerosols. Following these exposure sessions, the baby mice were suckled as normal. “We found the inhaled allergen in the mothers’ breast milk 3 to 4 hours after exposure”, explains one of researchers. “We also observed that once they reached adulthood, the young mice were resistant to asthma induction”.
Their allergic response was reduced by 60% to 80% compared with rodents suckled by mothers who had not been exposed to this allergen. “This study could help to determine new prevention strategies based, for example, on changes in breastfeeding practices and the quality of artificial milks”, the authors conclude. They also confirm the view that breast milk is best for babies.
