The flap over whether there are harmful levels of arsenic in certain brands of apple juice as alleged by Dr. Mehmet Oz and Consumer Reports has elicited some bizarre commentary. Dr. Manny Alvarez, senior managing health editor of FoxNews.com, said that arsenic levels in juices should not be tolerated at any level. “I don’t want to sound like an alarmist,” he said, “but just look at the growing levels of learning disabilities, autism spectrum disorders and other diseases that seem so prevalent today as compared to decades ago.”
Similarly, in experiments by Ronald Chesser, a radiation biologist at Texas Tech University, and his colleagues, mice exposed to low doses of radiation around Chernobyl for 10 to 45 days became resistant to damage from a higher, acute radiation dose delivered later in the lab.
