Consumer Reports tested 45 different fruit juices and found traces of heavy metals such as lead, arsenic, and cadmium in the juices. Heavy metals can be found in food due to air, soil, and water as well as during the manufacturing process. Overexposure to the metals can cause long-term effects such as cancer and kidney disease. Out of the 45 samples tested, 21 of them contained metals that Consumer Reports found dangerous for daily consumption. Of the 21 juices tested seven of them could do harm to children who drank a half a cup a day. Consumer Reports is warning that parent should limit their children’s drinking of packaged fruit juices and says their findings “shouldn’t be used to draw definitive conclusions about specific brands.”
