Dr. Mehmet Oz's comments about arsenic in the apple juice on The Dr. Oz Show Wednesday has been widely criticized by many including the Food and Drug Administration.
Oz, one of TV's most popular medical experts, said on his Fox show Wednesday that testing done by a New Jersey lab had found, what he suggested, troubling levels of arsenic in many brands of juice.
The show tested three dozen samples from five brands, and Oz claimed that 10 had more arsenic than the limit allowed in drinking water which is 10 parts per billion.
Without any doubt, Oz ignited a debate. The results of what the show described as an extensive national investigation have been seen by juice manufacturers, government regulators and scientists to be misleading and needlessly frightening to consumers.
The FDA said its own tests show no such thing, even on one of the same juice batches Oz cited.
In a statement, the FDA said, There is no evidence of any public health risk from drinking these juices.
Dr. Oz is a heart surgeon at Columbia University and heads an alternative medicine program at New York Presbyterian Hospital. He was a regular on Oprah Winfrey's show for many years before getting his own program two years ago.
Scientists say arsenic is a naturally occurring substance, and is so abundant in the Earth's soil that it often ends up in many of the foods we eat. However, experts make a distinction between this abundant organic arsenic, which is harmless and inorganic arsenic, which can be found in some pesticides and other chemicals.
