You possible know that mercury, lead, and different heavy metals will not be nice for the physique and may trigger a bunch of points. But whether or not or not fluoride is protected (or efficient) is extra controversial.

Is Fluoride Beneficial?

In the early a part of the 20 th century, it was found that small communities who had increased ranges of naturally occurring fluoride of their consuming water had fewer dental caries (cavities). Naturally fluoridated water at about 1mg/L appeared to be useful to dental well being. (Fluoride that’s naturally occurring is calcium fluoride.)

Unfortunately, the fluoride that’s usually added to water provides within the U.S. is hydrofluoric acid (an industrial by-product), not elemental fluorine or calcium fluoride. It’s well-known that naturally occurring substances (even heavy metals) are typically higher tolerated by the physique than artificial counterparts.

But as a result of early research confirmed few dental caries in communities utilizing fluoridated water, fluoridated water turned often called one in all 10 greatest public well being achievements of the 20 th century in response to the Center for Disease Control (CDC).

However, rates of dental caries have been going down for all western international locations, each utilizing fluoridation and never, suggesting that there isn’t any connection between fluoridated water and fewer cavities.

For instance, Sweden doesn’t fluoridate its water and has the identical quantity of dental caries because the United States. Nobel Prize Winner Dr. Arvid Carlsson argued towards its use in Sweden by saying that topical use of fluoride may match for dental caries however consuming fluoride was not a good suggestion, particularly when you think about that the quantity any particular person consumes can range fairly a bit.

Though some earlier research confirmed that fluoride within the water provide can assist cut back dental caries, a 2015 Cochrane assessment discovered that the newest and complete proof reveals that there’s merely not sufficient proof to assist fluoridating water.

Though fluoride might assist forestall cavities when used topically, there are different (higher) methods to enhance oral well being with out fluoride.

Sources of Fluoride

Fluoridated water is an apparent supply of fluoride however there are numerous others as properly. Because there are such a lot of sources of fluoride immediately, it’s particularly regarding that water provides are “spiked” with fluoride. Here are a few of the main sources of fluoride:

  • Packaged meals and drinks (made with fluoridated water)
  • Pesticides
  • Tea (the plant naturally absorbs fluoride; natural teas are fantastic)
  • Teflon pans
  • Mechanically separated meat (fragments of bone will be left behind)
  • Industry (aluminum, fertilizer, iron, oil refining, semi-conductor, and metal industries)
  • Fluorinated prescription drugs (the fluorine doesn’t often break down into fluoride, however might)
  • Dental merchandise

Of course, there are causes apart from fluoride to keep away from a few of the issues on this listing. For somebody who’s involved in pure well being (and avoiding a lot of these items already), avoiding fluoride isn’t all that onerous.

How Fluoride Affects the Thyroid

Though there may be some debate about whether or not fluoride is protected, the proof is fairly clear that it might probably have an effect on thyroid operate, and for anybody in danger to start with (many ladies are), fluoride is probably harmful. Considering thyroid illness impacts 20 million Americans (principally ladies), this is a vital angle to think about.

In the Nineteen Thirties a product containing fluoride was used to deal with folks with hyperthyroidism (overactive thyroid). The fluoride poisoned the enzymes within the thyroid gland and slowed down the manufacturing of thyroid hormones. This drug stopped getting used as a result of some folks’s thyroid glands have been completely broken from its use.

Studies present that fluoride impacts the thyroid gland particularly. Studies executed in India discovered that youngsters in communities with excessive fluoride consumption had a major lower in thyroid-stimulating hormone (TSH). Another examine discovered that folks with unfluoridated water have been much less more likely to develop hypothyroidism.

Fluoride and Iodine

Fluoride can result in thyroid irritation and autoimmune thyroid illness (like Hashimoto’s). Fluoride can be an endocrine disruptor. Dr. Izabella Wentz explains in this post the way it’s misidentified as iodine within the physique so it’s taken up into the physique and saved in physique tissues the way in which iodine must be.

One examine discovered that iodine ranges instantly affect how a lot hurt fluoride can do to the thyroid and will assist defend the thyroid from fluoride. On the opposite hand, many individuals who’ve thyroid illness like Hashimoto’s have low ranges of iodine however can’t tolerate supplemental iodine both. In these circumstances, fluoride is particularly problematic.

How Fluoride Affects the Skeletal System

Fluoride can be pretty clearly implicated in bone well being points. Though supporters of fluoride declare that it might probably assist enhance bone density, proof reveals that the quantity of fluoride performs a vital half in whether or not fluoride helps or hurts bone well being.

This study checked out totally different populations in China with various ranges of naturally occurring fluoride within the water starting from 0.25 mg/L to 7.97 mg/L (as a comparability, locations that add fluoride to water sometimes add to .7-1 mg/L). What the examine discovered was that fractures occurred much less when fluoride ranges have been at about 1 mg/L however extra after they have been on the bottom and highest elements of the vary. Clearly, there’s a fantastic line between useful and dangerous right here.

Skeletal fluorosis is a severe bone illness which causes hardening and thickening of the bones which makes motion troublesome. It will be confused with quite a lot of different skeletal points together with arthritis. Skeletal fluorosis is brought on by extreme publicity to fluoride which may occur over time as fluoride can accumulate within the physique. The most recent research reveals that early indicators of skeletal fluorosis can happen with as little as 6 mg of fluoride a day (a lot much less for these with kidney illness).

The Upside

Having good well being to start with, significantly regular ranges of nutritional vitamins and minerals, can assist cut back the detrimental results of fluoride. One examine discovered that ordinary ranges of calcium helped forestall fluoride-induced bone points in rats. Another discovered that enough ranges of vitamin D may very well be protecting. Additionally, one other examine discovered that magnesium-deficient rats absorbed extra fluoride than rats with regular magnesium ranges and likewise had extra fluoride of their bones and enamel.

What does this imply? That we are able to do one thing about fluoride publicity by doing a few of the identical issues which can be good for well being total. Optimizing calcium, vitamin D, and magnesium ranges (listed here are some concepts on that) and consuming a nutrient-dense weight-reduction plan is a superb first step.

Fluoride and the Brain

Fluoride is a confirmed neurotoxin and plenty of prestigious critiques have dug into the analysis that’s out there on the subject through the years. A 2012 Harvard assessment discovered that of the 27 research within the assessment, 26 of them concluded that there’s a relationship between elevated fluoride and diminished IQ.

A 2014 Lancet assessment paperwork fluoride as a neurotoxin that may very well be dangerous to little one growth. The assessment concludes, “The presumption that new chemicals and technologies are safe until proven otherwise is a fundamental problem.”

Newer analysis is discovering the identical neurotoxicity issues as earlier research. A 2017 examine discovered that fluoride publicity in utero was linked to poorer cognitive efficiency later in life.

Fluoride Affects Other Parts of the Body

While the consequences of fluoride on the thyroid, skeletal system, and mind is pretty clear reduce, the science is much less clear on how fluoride impacts different elements of the physique. Here are another methods fluoride might trigger hurt:

  • Cancer – A connection between fluoride and most cancers is a hotly debated matter, in all probability as a result of the analysis is inconclusive and at instances complicated.
  • Early sexual growth – One researcher discovered that fluoride accumulates in excessive quantities within the pineal gland (that secretes hormones). A 1997 examine discovered that fluoride was related to sooner sexual growth within the feminine gerbils within the examine.
  • Male infertility – Some information counsel {that a} decline in male fertility may very well be related to topical fluoride use. Animal research present concern however extra data is required.

So… Should I Be Worried About Fluoride?

There are many conflicting opinions on whether or not fluoride is protected and whether or not it’s one thing to fret about. (I do know, you hear me say issues like that so much!) Mark Sisson’s opinion on it’s that fluoride isn’t nice however that we must always concentrate on bettering well being in different methods first (clear weight-reduction plan, loads of sleep, low stress, and so forth) earlier than worrying about filtering fluoride from the water. On the opposite hand, in case you are filtering your water due to any variety of the opposite pollution that may very well be in it, chances are you’ll as properly filter out fluoride too.

There is proof on both aspect of the talk. My private stance is that for folks with thyroid points (like me) it’s clearly greatest to keep away from fluoride. And since fluoride does include a warning to name the poison management heart instantly if ingested (and after seeing a detailed buddy’s scare when her son ingested some fluoride), I purchase unfluoridated toothpaste and don’t hold fluoride-containing merchandise round our home.

How to Protect Teeth Without Fluoride

Though fluoride might have a protecting impact on enamel, there are different (higher) methods to maintain enamel wholesome than to smear them with fluoride.

Dental Diet

What you eat can affect your oral well being much more than brushing or flossing. Teeth are in a relentless state of remineralization because the saliva within the mouth gives minerals to the enamel and the cells within the enamel use these minerals to strengthen themselves.

Diet can play an enormous half on this course of (and the well being of your enamel). According to Weston A. Price’s (and others) analysis, a weight-reduction plan wealthy in wholesome fat, nutritional vitamins, and minerals can assist heal and defend oral well being. I’m going into extra element on this publish.

Balancing Hormones

Hormones can have an enormous impact on oral well being as they’ll management the acid/alkaline stability within the mouth. They additionally have an effect on how properly the physique can heal from or combat illness. Many of us have signs of hormone imbalance and issues like optimizing sleep, stress, weight-reduction plan, and health could make a giant distinction in hormone well being (and oral well being).

Homemade Toothpaste

Many typical sorts of toothpaste include chemical substances and synthetic substances that may do extra hurt than good! That’s why I began making my very own remineralizing toothpaste. I’ve been utilizing it for years and have had no new cavities (and have even healed some that have been ready for a filling).

Fluoride-Free Toothpaste

Of course making your personal toothpaste isn’t all the time sensible when life will get busy, so I created my very own line of private care merchandise based mostly on my DIY recipes. It’s known as Wellnesse and my Whitening Toothpaste is fluoride-free (however fights micro organism and decay with inexperienced tea leaf extract as an alternative!).

Fluoride: Bottom Line

There’s numerous conflicting proof surrounding fluoride and fluoridating water. Some companies and dentists assume fluoride use has been an enormous well being development. But there’s additionally rising proof that fluoride will be dangerous. I wish to go on the aspect of warning (particularly when there are pure methods to enhance oral well being) and keep away from it. We use a water filter that removes fluoride as properly.
