A new research study published in Nature Communications has found a possible link between heavy metals such as lead and zinc and autism. The study examined 32 sets of baby teeth from twins to check for any correlation between exposure to heavy metals and an increased risk of developing autism. According to ABC News, “Of these 32 pairs of twins, six had only one twin with autism spectrum disorder, seven had both twins had autism spectrum disorder and 19 were unaffected by autism spectrum disorder.”
Could this be an indication that researchers are getting to the environmental risk for autism? Only time and more research will tell….
