A new study by British scientists which was recently published in the American Journal of Respiratory and Critical Care Medicine suggests that babies who are breastfed frequently and for a longer duration were more likely to have stronger lungs than babies fed primarily formula and baby food.
The study kept track of 1,500 children ranging in age from 8-14. The longer children were breastfed as babies, the better they performed on lung function tests years down the road.
The study also found that children who were profusely breastfed were less likely to develop asthma (possibly due to the vitamin D present in breast milk - although that is this author's speculation, just to be clear). This is true even for children whose mothers had been diagnosed with asthma, provided the children were breastfed for a minimum of four months. These children also performed better on tests measuring lung capacity, suggesting that breastfed babies were that much less likely to develop asthma.
Breastfeeding has been shown to have a myriad of profound effects on the overall health of babies, including their health as they grow up into children.
