Study: Formula fed babies have higher arsenic levels than breast fed babies

Posted: Updated:

Babies who are formula fed have arsenic levels that are 7.5% higher than babies who are breastfed, according to a study done by researchers at Dartmouth College.

The study published in "Environmental Health Perspectives" looked at the arsenic levels from home tap water, breast milk and urine from a group of six-week-olds, and found that, in most cases, powder and water used for formula was a contributing factor to the higher arsenic levels.

In large doses, arsenic can cause serious problems, so the researchers say that families who get their water from private wells should be their water tested for contamination.
