The internet is flooded with articles linking autism and mercury exposure. A new study, however, suggests that children with autism have lower levels of mercury in their bloodstreams.
This study relates to the mercury found in fish. Children with autism tend to be very picky eaters, which may play an crucial role in the low mercury level found in their bodies
Irva Hertz-Picciotto, a professor of public health sciences at the University of California, Davis, who was the study’s principal investigator, makes a point to point out, “We were measuring levels after the diagnosis had already been made and was months in the past in most cases,” Dr. Hertz-Picciotto said. “So this study does not provide evidence for or against” mercury’s role as a causal agent.”
