Baby Formula Poses A More Serious Arsenic Risk Than Breast Milk

Healthy mothers who want to breastfeed their babies are offering them an optimal natural source of high nutrition. Dartmouth College reported on Feb. 23, 2015, formula poses a greater arsenic risk than breast milk. Dartmouth researchers observed that formula fed infants had higher arsenic levels than infants who were breastfed.

Co-lead author Kathryn Cottingham, who is a professor of biological sciences at Dartmouth, says the results of this study have suggested that breastfeeding can decrease arsenic exposure even at the relatively low levels of arsenic which are generally seen in the United States. This offers us a very important public health benefit of breastfeeding.

Arsenic has been found to occur naturally in bedrock and is a common contaminant of well water worldwide. Arsenic causes cancers and other diseases. Exposure to arsenic early in life has been associated with increased fetal mortality, decreased birth weight, and lowered cognitive function. The Environmental Protection Agency has set a maximum contaminant level of arsenic for public drinking water. However, private well water is not subject to regulation and is the primary source of water in many rural areas in the United States.

This study has been published in the journal Environmental Health Perspectives. It has been found in previous studies that there are relatively low breast milk arsenic concentrations even in areas which have high drinking water arsenic levels. The results from this study have suggested that breastfed infants have lower arsenic exposure than infants who are formula fed. This finding should serve as an incentive for healthy mothers to breastfeed their babies.
