Ninety-five percent of baby foods in the U.S. contain either lead, arsenic, mercury or cadmium. That’s according to a shocking new national study by Healthy Babies Bright Futures, which tested 61 different baby food brands purchased across 14 different metropolitan areas — from San Diego, California, to Albany, New York. The study found that nearly all of the baby foods tested were contaminated with at least one of the developmental neurotoxins. One in four of the tested baby foods contained all four types of the heavy metals, which are each linked to IQ loss from exposures early in life. In response to the study, New York Democratic Senator Chuck Schumer is calling on the Food and Drug Administration to examine the study and release a public statement on its findings.
