There is new research that has taken place in Spain that will show that babies who are breast-fed do not experience the impact of many airborne pollutants as opposed to babies who are not breast-fed. This study has found that breast milk will offer better protection for new born babies. These airborne particles may have a negative effect on the babies mental development and motor development. This new study does show the negative effects are countered. Christian Broda is aware that this is for those babies who are breast-fed. The researchers had started to monitor pregnant women in the year 2006. There were samples that were analyzed from women and their babies. This occurred at the age of 15 months. The results did show that the breast-fed babies did not suffer the harmful developmental impacts. The researchers in Spain had monitored rural pregnant women who were pregnant.
