New Study Quantifies Fluoride’s Potential to Lower IQ in Children
Some
children may be consuming enough fluoridated water in the USA to reach
doses of fluoride that have the potential to lower their IQ, according
to a research team headed by William Hirzy, PhD, a former US EPA senior
scientist who specialized in risk assessment and published in the
journal Fluoride (Oct-Dec 2016), reports the Fluoride Action Network (FAN).
Current
federal guidelines encourage the addition of fluoride chemicals into
water supplies to reach 0.7 milligrams per liter ostensibly to reduce
tooth decay. Hirzy followed EPA risk assessment guidelines to report:
“The
effect of fluoride on IQ is quite large, with a predicted mean 5 IQ
point loss when going from a dose of 0.5 mg/F/day to 2.0 mg F/day.”
Many
children in the U.S. commonly consume levels of fluoride within this
range from all sources (i.e. water, food, dental products, medicines,
air pollution).
Dr. Hirzy explains the significance of this study:
The
significance of this peer reviewed risk analysis is that it indicates
there may be no actual safe level of exposure to fluoride.
Groups
of children with lower exposures to fluoride were compared with groups
having higher exposures. Those with higher exposures performed more
poorly on IQ tests than those with lower exposures.
One
well-conducted Chinese study indicated that children exposed to 1.4
mg/day had their IQ lowered by 5 IQ points. Current average mean daily
intakes among children in the United States are estimated by EPA to
range from about 0.80 mg/day to 1.65 mg/day.
Applying
two different, standard risk analysis techniques used by the U.S. EPA
to published data on the impact of fluoride exposure in children shows
that daily intakes in excess of about 0.05 mg of fluoride may result in
depressed intellectual capability. This calculation involved using
safety factors designed to protect the most vulnerable child.
Fluoride may be similar to lead and mercury in having no threshold below which exposures may be considered safe.
Bill Osmunson, DDS, FAN’s Interim Director noted that this study adds further weight to a Petition submitted to the US EPA by FAN and other groups
in November to ban the addition of fluoride chemicals to the drinking
water under provisions in the Toxic Substances Control Act. The EPA has
until Feb 20 to rule on this Petition.
Fluoride is a poison. Fluoride was poison yesterday. Fluoride is poison today. Fluoride will be poison tomorrow. What amazes me is that our school system promote fluoride even though it has been shown to lower IQ. Even though fluoride is more poison than lead our school systems somehow treats fluoride as the student's friend and lead as something toxic, which of course it is. If I were a student I would be very confused on this issue. When in doubt get it out.
