Fluoride is a mineral that exists naturally in water and soil. About 70 years ago, scientists discovered that people who lived where water supplies naturally had more fluoride also had fewer cavities. Some locales have naturally occurring fluoridation levels above 1.2 mg/L. Today, most public drinking water supplies are fluoridated, especially in larger cities. Counting everyone, including those who live in rural areas, about 64% of Americans drink fluoridated water.
There has been a long going debate about fluoride in tap water, and in several recent studies and reports, fluoride has been linked to many health concerns. The Associated Press notes, “A scientific report five years ago said that people who consume a lifetime of too much fluoride — an amount over EPA's limit of 4 milligrams — can lead to crippling bone abnormalities and brittleness.” Other research and reports focus on the adverse effects that fluoride has on intelligence. In 2006, the National Academy of Science released a report that reviewed scientific studies which found that fluoride actually has negative effects on a child’s intelligence (NAP Study, EHP Study, Artigo Article). Even skeptical experts have said that the results of the studies done by the National Academy of Science are plausible, since it is known that fluoride affects the thyroid hormone which in turn affects intelligence, not to mention that fluoride is also a known neurotoxicant. Revisiting these studies, along with the new research issued Friday by the EPA about the negative health effects of fluoride, are sure to re-energize groups that continue to oppose adding it to our nations water supplies.
We can venture a guess and say that most of us still believe that fluoride should be added to tap water because it helps prevent tooth decay, and helps to protect our teeth from cavities. But in the newest report - issued Friday January 7th, 2011 - scientific evidence is now supporting a different conclusion: that too much fluoride can actually cause more harm than good to our teeth. In this new report, health officials have reported that nearly 2 out of every 5 teenagers has tooth streaking or spottiness as a result of too much fluoride. In extreme cases where very high levels of fluoride are found, a person’s teeth can even be pitted by the mineral - something dentists have started to notice. According to data collected by the CDC, about 23% of children ages 12-15 had fluorosis in a study conducted in 1986 and 1987. That percentage rose to 41% in the more recent study, which covered the years 1999 through 2004.
Currently, the standard since 1962 for fluoride in drinking water has been set at a range of 0.7 to 1.2 milligrams per liter of water. Armed with the new research, The U.S. Department of Health and Human Services is announcing a proposal to change the recommended fluoride level to 0.7 milligrams per liter of water. After the recommendation is made, the Environmental Protection Agency (EPA) will then review whether the current maximum cutoff of 4 milligrams per liter is too high. What areas of the country have the highest levels of fluoride in their water? Reports have shown that Maryland is the most fluoridated state, with nearly every resident on a fluoridated water system. On the other end of the spectrum, only about 11% of Hawaii residents are on fluoridated water, according to government statistics.
So why not just use bottled water? Well, the first thing that most of us fail to realize is the cost of bottled water compared to water from the tap. Did you know that bottled water cost hundreds of times more than filtered water from your tap? Secondly, bottled water and tap water are regulated by different federal agencies. Recently some manufacturers have started adding fluoride to their bottled water products. The FDA does not require bottled water manufacturers to list the fluoride content on the label, but it does require that fluoride additives be listed. In 2006, the FDA approved labeling with the statement, “Drinking fluoridated water may reduce the risk of tooth decay,” for bottled water that contained from 0.6 mg/L to 1.0 mg/L. If the manufacturer does not list the fluoride contents, the only thing you can do is contact the bottled water’s manufacturer to ask about the fluoride content of a particular brand. Obviously, in light of the most recent report and study, fluoride being added to bottled water is bound to change.
So what types of water filter systems help reduce the amounts of fluoride in household tap water? How do you take you water on the go with you? There are two primary types of systems that help effectively filter fluoride from water, a reverse osmosis system and a water distillation system. Then to keep the same conveniences of bottled water try using an eco-friendly reusable steel water bottle.
Reverse Osmosis Drinking Water Systems: A reverse osmosis water filtration system is one of the most common treatment methods for household drinking water because of its ability to remove fluoride and a variety of other water contaminants. Easy to install, low maintenance, and great cost per gallon of water compared to bottled water and drinking water systems.
Water Distillers: Countertop water distillation systems offer 99.9% pure water by removing unwanted and harmful water contaminants more effectively than other water purification systems that are currently on the market. Operation is simple, and has a low cost because there are no filters or other components that require frequent changes.
