New Study: Breastfed Babies Have Lower Exposure to Arsenic

A new study, by Dartmouth College researchers, shows babies that are breastfed exhibit less signs of arsenic exposure than babies that drink formula.

From a press release:

The researchers measured arsenic in home tap water, urine from 72 six-week-old infants and breast milk from nine women in New Hampshire. Urinary arsenic was 7.5 times lower for breast-fed than formula-fed infants. The highest tap water arsenic concentrations far exceeded the arsenic concentrations in powdered formulas, but for the majority of the study's participants, both the powder and water contributed to exposure.

“This study‘s results highlight that breastfeeding can reduce arsenic exposure even at the relatively low levels of arsenic typically experienced in the United States,” says lead author Professor Kathryn Cottingham. “This is an important public health benefit of breastfeeding.”
