Study: Formula-fed babies have higher levels of arsenic than breastfed babies
(CNN) — Researchers at Dartmouth College did a study on infant nutrition and found that formula-fed babies had seven-and-a-half times higher arsenic levels than babies who were breastfed.
Researchers measured arsenic in home tap water, breast milk and the urine from 72 six-week-old infants.
For the majority of the study’s participants, both the powder and water used to make the baby formula contributed to arsenic exposure.
The study’s authors say in large doses arsenic can lead to serious health problems.
The study says breastfeeding can reduce arsenic exposure and families with private wells should have their tap water tested for contamination.
The study appears in the journal “Environmental Health Perspectives.”
