You probably know that mercury, lead, and other heavy metals aren’t nice for the physique and may trigger a bunch of points. However whether or not or not fluoride is protected (or efficient) is extra controversial.

Is Fluoride Useful?

Within 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 gave the impression to be useful to dental well being. (Fluoride that’s naturally occurring is calcium fluoride.)

Sadly, 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 usually higher tolerated by the physique than artificial counterparts.

However as a result of early research confirmed few dental caries in communities utilizing fluoridated water, fluoridated water grew to become generally known as one in all 10 greatest public well being achievements of the 20 th century in keeping with the Middle for Illness Management (CDC).

Nonetheless, rates of dental caries have been going down for all western nations, 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 as the US. Nobel Prize Winner Dr. Arvid Carlsson argued in opposition to its use in Sweden by saying that topical use of fluoride may fit 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.

Although some earlier research confirmed that fluoride within the water provide will help scale back dental caries, a 2015 Cochrane evaluation discovered that the newest and complete proof reveals that there’s merely not sufficient proof to help fluoridating water.

Although fluoride might assist stop 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 lots of others as nicely. As a result of there are such a lot of sources of fluoride at the moment, it’s particularly regarding that water provides are “spiked” with fluoride. Listed here are among the main sources of fluoride:

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

After all, there are causes apart from fluoride to keep away from among 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 arduous.

How Fluoride Impacts the Thyroid

Although there may be some debate about whether or not fluoride is protected, the proof is fairly clear that it will possibly have an effect on thyroid operate, and for anybody in danger to start with (many women are), fluoride is doubtlessly harmful. Contemplating thyroid illness impacts 20 million People (largely girls), this is a crucial angle to think about.

Within 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 had been completely broken from its use.

Research present that fluoride impacts the thyroid gland particularly. Research finished in India discovered that youngsters in communities with excessive fluoride consumption had a big lower in thyroid-stimulating hormone (TSH). One other examine discovered that individuals with unfluoridated water had 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 best way iodine needs to be.

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

How Fluoride Impacts the Skeletal System

Fluoride can be pretty clearly implicated in bone well being points. Although supporters of fluoride declare that it will possibly assist enhance bone density, proof reveals that the quantity of fluoride performs an important 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 had been at about 1 mg/L however extra once they had been on the bottom and highest elements of the vary. Clearly, there’s a nice 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 may be confused with quite a lot of different skeletal points together with arthritis. Skeletal fluorosis is attributable to extreme publicity to fluoride which might 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, notably regular ranges of nutritional vitamins and minerals, will help scale back the detrimental results of fluoride. One examine discovered that standard ranges of calcium helped stop fluoride-induced bone points in rats. One other discovered that ample ranges of vitamin D might be protecting. Moreover, 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 tooth.

What does this imply? That we are able to do one thing about fluoride publicity by doing among the similar issues which can be good for well being general. Optimizing calcium, vitamin D, and magnesium ranges (here are some ideas on that) and consuming a nutrient-dense food regimen is a good first step.

Fluoride and the Mind

Fluoride is a confirmed neurotoxin and lots of prestigious critiques have dug into the analysis that’s obtainable on the subject over time. A 2012 Harvard evaluation discovered that of the 27 research within the evaluation, 26 of them concluded that there’s a relationship between elevated fluoride and diminished IQ.

A 2014 Lancet evaluation paperwork fluoride as a neurotoxin that might be dangerous to baby growth. The evaluation concludes, “The presumption that new chemical compounds and applied sciences are protected till confirmed in any other case is a basic drawback.”

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 Impacts Different Components of the Physique

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

  • Most cancers – A connection between fluoride and most cancers is a hotly debated subject, in all probability as a result of the analysis is inconclusive and at occasions 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 quicker sexual growth within the feminine gerbils within the examine.
  • Male infertility – Some knowledge counsel {that a} decline in male fertility might be related to topical fluoride use. Animal research present concern however extra data is required.

So… Ought to I Be Fearful About Fluoride?

There are lots of 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 rather a lot!) Mark Sisson’s opinion on it’s that fluoride isn’t nice however that we must always give attention to bettering well being in different methods first (clear food regimen, loads of sleep, low stress, and many others) earlier than worrying about filtering fluoride from the water. Then again, if you’re filtering your water due to any variety of the opposite pollution that might be in it, chances are you’ll as nicely filter out fluoride too.

There may be proof on both aspect of the controversy. 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 middle instantly if ingested (and after seeing a detailed good friend’s scare when her son ingested some fluoride), I purchase unfluoridated toothpaste and don’t preserve fluoride-containing merchandise round our home.

Easy methods to Defend Tooth With out Fluoride

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

Dental Weight loss program

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

Weight loss program can play an enormous half on this course of (and the well being of your tooth). In accordance with Weston A. Value’s (and others) analysis, a food regimen wealthy in wholesome fat, nutritional vitamins, and minerals will help heal and shield oral well being. I am going into extra element in this post.

Balancing Hormones

Hormones can have an enormous impact on oral well being as they’ll management the acid/alkaline stability within the mouth. Additionally they have an effect on how nicely the physique can heal from or combat illness. Many people have signs of hormone imbalance and issues like optimizing sleep, stress, food regimen, and health could make a big difference in hormone health (and oral well being).

Do-it-yourself Toothpaste

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

Fluoride-Free Toothpaste

After all making your personal toothpaste isn’t at all times sensible when life will get busy, so I created my very own line of private care merchandise primarily based 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 a substitute!).

Fluoride: Backside Line

There’s a number of conflicting proof surrounding fluoride and fluoridating water. Some businesses and dentists assume fluoride use has been an enormous well being development. However there’s additionally rising proof that fluoride could be dangerous. I prefer 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 nicely.
