A new study out of Dartmouth says organic foods made with brown rice syrup can have high levels of arsenic. How might that affect your little one? The study also found that some organic toddler formulas that use brown rice syrup contained 6 times the level of arsenic the EPA considers safe in drinking water. The lead researcher, environmental chemist Brian P. Jackson, called those levels "dangerous amounts of arsenic," particularly when you consider a toddler's size. If you're feeding your toddler an organic formula, Jackson told ABC News that it's wise to "choose one that wasn't based on brown rice syrup."
