Results of Fluoride on Thyroid & Physique | Wellness Mama

Desk of Contents[Hide][Show]

You probably know that mercury, lead, and other heavy metals will not be nice for the physique and might trigger a number 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 larger ranges of naturally occurring fluoride of their ingesting water had fewer dental caries (cavities). Naturally fluoridated water at about 1mg/L gave the impression to be helpful 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 typically 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 turned often called one among 10 greatest public well being achievements of the 20 th century based on the Middle for Illness Management (CDC).

Nonetheless, 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 as the USA. Nobel Prize Winner Dr. Arvid Carlsson argued towards its use in Sweden by saying that topical use of fluoride may go for dental caries however ingesting fluoride was not a good suggestion, particularly when you think about that the quantity any particular person consumes can fluctuate fairly a bit.

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

Although fluoride could 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 various others as nicely. As a result of there are such a lot of sources of fluoride at present, it’s particularly regarding that water provides are “spiked” with fluoride. Listed below 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 may be left behind)
  • Business (aluminum, fertilizer, iron, oil refining, semi-conductor, and metal industries)
  • Fluorinated prescribed drugs (the fluorine doesn’t normally break down into fluoride, however could)
  • Dental merchandise

After all, there are causes apart from fluoride to keep away from a few of the issues on this listing. For somebody who’s enthusiastic about pure well being (and avoiding lots of these items already), avoiding fluoride isn’t all that tough.

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 probably have an effect on thyroid operate, and for anybody in danger to start with (many women are), fluoride is probably harmful. Contemplating thyroid illness impacts 20 million Individuals (largely girls), this is a vital angle to think about.

Within the Thirties a product containing fluoride was used to deal with individuals 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 individuals’s thyroid glands had been completely broken from its use.

Research present that fluoride impacts the thyroid gland particularly. Research completed in India discovered that youngsters in communities with excessive fluoride consumption had a major lower in thyroid-stimulating hormone (TSH). One other examine discovered that folks with unfluoridated water had been much less prone to develop hypothyroidism.

Fluoride and Iodine

Fluoride can result in thyroid irritation and autoimmune thyroid illness (like Hashimoto’s). Fluoride can also 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 ought 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. Alternatively, 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 Impacts the Skeletal System

Fluoride can also be pretty clearly implicated in bone well being points. Although supporters of fluoride declare that it will probably assist enhance bone density, proof exhibits 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 usually 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 after they had been on the bottom and highest components 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 tough. It may be confused with quite a few 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 exhibits 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, might help cut back the unfavourable results of fluoride. One examine discovered that ordinary ranges of calcium helped forestall fluoride-induced bone points in rats. One other discovered that adequate ranges of vitamin D could possibly 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 enamel.

What does this imply? That we will do one thing about fluoride publicity by doing a few of the identical issues which might be good for well being general. Optimizing calcium, vitamin D, and magnesium ranges (here are some ideas on that) and consuming a nutrient-dense weight loss program is a good first step.

Fluoride and the Mind

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

A 2014 Lancet overview paperwork fluoride as a neurotoxin that could possibly be dangerous to little one improvement. The overview concludes, “The presumption that new chemical substances and applied sciences are protected till confirmed in any other case is a elementary downside.”

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 components of the physique. Listed below are another methods fluoride could trigger hurt:

  • Most cancers – A connection between fluoride and most cancers is a hotly debated matter, most likely as a result of the analysis is inconclusive and at instances complicated.
  • Early sexual improvement – 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 improvement within the feminine gerbils within the examine.
  • Male infertility – Some knowledge counsel {that a} decline in male fertility could possibly be related to topical fluoride use. Animal research present concern however extra data is required.

So… Ought to I Be Frightened About Fluoride?

There are numerous 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 lots!) Mark Sisson’s opinion on it’s that fluoride isn’t nice however that we must always deal with bettering well being in different methods first (clear weight loss program, loads of sleep, low stress, and many others) earlier than worrying about filtering fluoride from the water. Alternatively, in case you are filtering your water due to any variety of the opposite pollution that could possibly be in it, chances are you’ll as nicely filter out fluoride too.

There may be proof on both facet of the talk. My private stance is that for individuals 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 an in depth buddy’s scare when her son ingested some fluoride), I purchase unfluoridated toothpaste and don’t hold fluoride-containing merchandise round our home.

The best way to Shield Enamel With out Fluoride

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

Dental Food regimen

What you eat can affect your oral well being much more than brushing or flossing. Enamel are in a continuing 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.

Food regimen can play an enormous half on this course of (and the well being of your enamel). In keeping with Weston A. Value’s (and others) analysis, a weight loss program wealthy in wholesome fat, nutritional vitamins, and minerals might 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 will management the acid/alkaline steadiness within the mouth. Additionally they have an effect on how nicely the physique can heal from or struggle illness. Many people have signs of hormone imbalance and issues like optimizing sleep, stress, weight loss program, and health could make a big difference in hormone health (and oral well being).

Home made Toothpaste

Many typical sorts of toothpaste include chemical substances 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 based mostly on my DIY recipes. It’s referred to 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 lot of conflicting proof surrounding fluoride and fluoridating water. Some businesses and dentists suppose fluoride use has been an enormous well being development. However there’s additionally rising proof that fluoride may be dangerous. I prefer to go on the facet 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.
