In 2012, the Harvard School of Public Health released a study linking fluoridated water (along with other chemicals) to cognitive and behavioral disorders. According to the study,"[f]luoride readily crosses the placenta. Fluoride exposure to the developing brain, which is much more susceptible to injury caused by toxicants than is the mature brain, may possibly lead to permanent damage." Despite this study from a well-respected institution, it has yet to become mainstream thinking. Cities across the US continue to add fluoride to the water and those who fight it are considered fringe freaks. And we continue to "wonder" why on earth there has been such an increase in autism spectrum disorders.
Many of the chemicals that we use in our everyday lives are rarely tested and we know nothing about the effects of the toxic soup created by releasing multitudes of chemicals into our environment. The bottom line is we should avoid as many chemicals as possible and use the most basic, natural ingredients in our homes, yards, food, clothing, and personal care products. History will prove this to be the best route to optimum health and a clean environment.
