Seven Reasons Why You Should Avoid Fluoride In Water

There seems to be no good reason to systemically increase fluoride levels in the body
by adding it to the public water supply.

Scientific reviews provide strong evidence that excess fluoride in water is dangerous to human health and may not even prevent cavities. So why do two out of every three Americans drink fluoridated tap water or use it in cooking, and for brushing their teeth?

We’ve based fluoridation on outdated research originating from the 1940s. Old research models are sometimes classics: once true always right. Older models are often wrong, however, or at best partially right.

The latest research results challenge the safety of fluoride treated water. A Cochrane systematic review published online in June 2015 found that since 1975, only three out of 107 studies support the premise that fluoride reduces cavities.

Fluoride is not an essential nutrient. No nutritional deficiency is associated with lack of fluoride. It has been used as a drug to improve public health, but I suspect that’s not only a flawed policy, but may also lead to disease.

Seven Conditions Associated With Too Much Fluoride

  1. Impaired learning
  2. Memory deficit
  3. Attention deficit hyperactivity disorder
  4. Impairment of brain development in children
  5. Impaired thyroid function
  6. Dental fluorosis
  7. Skeletal fluorosis
Fluoride and ADHD

Scientists at York University in Toronto linked fluoridation of drinking water to attention deficit hyperactivity disorder (ADHD). In states like Iowa and Delaware, with high levels of fluoridated water, the prevalence of ADHD is greater than the average population.

For years, observational studies by the CDC indicated that as the percentage of Americans who drank fluoridated water increased, so did the percent of children diagnosed with ADHD. The ecological association between fluoride and ADHD is huge.

Fluoride and Hypothyroidism

In the Journal of Epidemiology & Community Health, scientists found a greater percentage of hypothyroidism in areas with fluoridated water. Too much fluoride also damages the parathyroid glands.

Dental Fluorosis

Too much fluoride causes a condition called fluorosis, staining and mottling of the teeth. Dentists consider mild fluorosis an aesthetic problem. A few white flecks on your teeth suggest mild fluorosis. Moderate levels show up as darker spots that cover more that 50% of teeth surfaces.

Severe fluorosis causes calcification of ligaments. Advanced fluorosis cause bone and joint disease. In its early stages, skeletal fluorosis manifests the same symptoms as osteoarthritis: joint pain and stiffness.

Fluoridosis may be an indicator of wider disease and systemic environmental damage. Besides the known problems associated with too much fluoride, other conditions, including impaired kidney function and increased bone fractures in elderly people with osteoporosis, may also be associated with the compound.


Young Children Are Overexposed To Fluoride

Not only do children with fluorosis have brown teeth, they also have lower IQs. More than 40 scientific studies found that fluoride exposure impairs learning and memory, and can cause neurological damage in young children.

Fluoride Is An Industrial Chemical

The source of fluoride in most public water supplies is fluorosilicic acid, a byproduct of manufacturing phosphate fertilizers and other industrial products. Fluorosilicic acid is a toxic chemical waste product that should not be allowed in the public water supply or in human or animal food. It is classified as a hazardous substance by the U.S. government.

In 2014, The Lancet published a report on neurotoxicity associated with industrial chemicals, including fluoride. Researchers found that manmade chemicals in the environment doubled from 2006 to 2014. They termed the consequences a “pandemic” of developmental neurotoxicity, and proposed an international clearinghouse to screen industrial chemicals with a goal of tighter control of new chemicals and testing of existing ones, including pesticides.

Protect Yourself From Fluoridation

Understandably, the consequence of tooth decay constitutes a significant health problem. However, there are other ways to not only prevent but eradicate tooth decay, including healthy nutrition, regular brushing and routine dental care, and the elimination of refined sugar and wheat products from the diet.

Despite the growing evidence to the contrary, the CDC maintains that fluoridation is safe and effective. Researchers are calling for the CDC and other health agencies to make fluoride safety research high priority.

A practice that at one time might have made sense, but is no longer scientifically useful, needs to be stopped. There seems to be no good reason to systemically increase fluoride levels in the body by adding it to the public water supply. In fact, the evidence is clear that too much fluoride causes considerable harm.

    Great article, but few people listen. Have reverse osmosis system, to filter out flouride, and chemicals. Use it for cooking, even keep glass on bathroom sink with half filtered water and hydrogen peroxide. Use for brushing teeth and rinsing. Keeps teeth white. Most people do not like taste of city water, so then do not drink enough water.
