A leading cause of #‎ADHD (attention-deficit hyperactivity disorder) and autism in children could be the hidden chemicals lurking in the foods we eat, the water we drink and the products we consume, says a new study recently published in The Lancet. #‎Researchers from the Harvard #‎School of Public Health (HSPH) and the Icahn #‎SchoolofMedicine at #‎MountSinai (ISMMS) found that, among other things, the fluoride chemicals added to many public water systems in North America directly contribute to both mental and behavioral disorders in children.
