Studies Show Zinc-Copper Rhythmicity and Zinc Levels May Play a Role

A study released in Science Advances shows that baby teeth can show the relationship between copper and zinc— levels present both in-utero and post-natally—can be a predictor in diagnosing autism.

According to study authors, “Using novel tooth-matrix biomarkers that provide direct measures of fetal elemental uptake, we developed a predictive model to distinguish participants who would be diagnosed with ASD in childhood from those who did not develop the disorder.”

The study authors used laser ablation to take 152 samples from each tooth. Children while in utero and in the early months of life, add a new layer to their baby teeth before they erupt. Researchers found that using these samples, they could predict with 90% accuracy which children would later develop autism.

Earlier studies such as one from Australia that links zinc deficiency to communications issues in brain cells. Children with autism frequently have zinc deficiencies. Now researchers must determine if zinc supplementation will help and if so, at what levels. Too much zinc can be toxic.
