Thyroid Deficiency Linked to Iodine Deficiency and Fluoridated Water


Greater than 66 % of the U.S. inhabitants drinks water with added fluoride,1 even supposing research proceed to query its security and usefulness for its said objective: stopping cavities. A lot of nations — together with Germany, Sweden, Japan, the Netherlands, Finland and Israel — have already stopped this hazardous follow, however many Individuals are nonetheless in danger.

In Canada, practically 39 % of the inhabitants additionally receives fluoridated consuming water (in contrast with solely about 3 % of Europeans).2 It has been recognized for years that fluoridated water consumption is linked to thyroid dysfunction and behavioral issues like consideration deficit hyperactivity dysfunction (ADHD), and two new research have added to the already obvious associations.

Publicity to Fluoridated Water Could Disrupt Thyroid Functioning

Your thyroid gland, situated within the entrance of your neck, influences virtually each cell in your physique. Thyroid hormones regulate your metabolism and are required for development and improvement in youngsters and practically each physiological course of in your physique.

When your thyroid ranges are unbalanced, it may result in a cascade of issues all through your physique. In hypothyroidism, the commonest thyroid dysfunction, your thyroid gland exercise is suppressed.

Also referred to as underactive thyroid, many with this situation are unaware they’ve it, and one other 4 to 10 % of the U.S. inhabitants might undergo from subclinical hypothyroidism that’s missed by testing but related to miscarriage, preterm start and altered development and neurodevelopment in infants.

Even reasonably imbalanced thyroid ranges could also be related to elevated threat of metabolic syndrome, researchers famous within the journal Atmosphere Worldwide, which is why “learning components that contribute to low thyroid perform, even on the subclinical degree, is of excessive public well being significance.”3

Notably, subclinical hypothyroidism is recognized by excessive serum thyroid-stimulating hormone (TSH) concentrations, and “fluoride in consuming water, even at ranges as little as 0.3–0.5 mg/L, have predicted elevated TSH concentrations,” the researchers added. “Greater water fluoride concentrations have additionally predicted an elevated probability of a hypothyroidism prognosis amongst adults.”4

The newest research, which concerned knowledge from practically 7 million Canadian adults not taking any thyroid-related remedy, discovered that greater fluoride ranges weren’t related to greater TSH ranges within the normal inhabitants; nonetheless, when iodine standing was accounted for, the outcomes shifted.

Iodine Deficiency Could Heighten the Dangers of Fluoridated Water

Your physique makes use of iodine throughout a number of organ techniques, however it’s mostly recognized to synthesize thyroid hormones. Clinically low ranges of iodine are related to seen signs, akin to a goiter (swelling of the thyroid gland), hypothyroidism or pregnancy-related issues. Nonetheless, subclinical iodine deficiency also can intervene together with your thyroid perform.

In the meantime, the Canadian research revealed that adults in Canada who’ve moderate-to-severe iodine deficiencies and better fluoride ranges are likely to have greater TSH ranges, which signifies they could be at an elevated threat for underactive thyroid gland exercise.5

It is a startling discovering, contemplating practically 2 billion individuals worldwide do not get sufficient iodine of their food regimen.6 Because the researchers of the featured research famous, because of this these with iodine deficiency could also be at a fair larger elevated threat from consuming fluoridated water:7

“Iodine deficiency can contribute to decreased thyroid hormone manufacturing and exacerbate the thyroid-disrupting results of sure chemical compounds, in addition to fluoride …

Fluoride exposures of 0.05 to 0.13 mg/kg/day have been related to hostile thyroid results amongst iodine enough individuals, whereas decrease fluoride exposures of 0.01 to 0.03 mg/kg/day have been related to these results amongst iodine poor individuals.”

The consequences had been so worrying that lead research writer Ashley Malin, a researcher on the division of environmental medication and public well being, Icahn Faculty of Drugs at Mount Sinai, instructed Environmental Well being Information:8

“I’ve grave considerations concerning the well being results of fluoride publicity … And never simply from my research however the different research which have come out lately … We’re speaking about doubtlessly [more than] one million individuals vulnerable to an underactive thyroid attributable to fluoride publicity.”

In 2015, as an illustration, British researchers warned that 15,000 individuals could also be bothered with hypothyroidism within the U.Ok. on account of consuming fluoridated water.9 In areas the place fluoride ranges within the water registered above 0.3 mg/l, the danger of getting a excessive charge of hypothyroidism was 37 % larger in comparison with areas that don’t fluoridate.

Pregnant Ladies Consuming Fluoridated Water Have Greater Fluoride Ranges

Fluoride publicity can happen from a number of sources, starting from tea and processed meals to dental merchandise, prescribed drugs and fluoride-containing pesticides. Nonetheless, analysis continues to point out that consuming water stays a main route of publicity, together with in pregnant girls.

In a research of greater than 1,500 pregnant girls dwelling in Canada, these dwelling in communities with fluoridated consuming water have two instances the quantity of fluoride of their urine as girls dwelling in nonfluoridated communities.10

“Analysis is urgently wanted to find out whether or not prenatal publicity to fluoride contributes to neurodevelopmental outcomes within the offspring of those girls,” researchers defined.11 In reality, analysis has beforehand revealed that girls with greater ranges of fluoride of their urine throughout being pregnant had been extra more likely to have youngsters with decrease intelligence.

Particularly, every 0.5 milligram per liter improve in pregnant girls’s fluoride ranges was related to a discount of three.15 and a couple of.5 factors on the youngsters’s Common Cognitive Index (GCI) of the McCarthy Scales of Youngsters’s Skills and Wechsler Abbreviated Scale of Intelligence (WASI) scores, respectively.

Lead researcher Dr. Howard Hu, of the Dalla Lana Faculty of Public Well being on the College of Toronto in Canada, mentioned in a information launch:12

“Our research reveals that the rising fetal nervous system could also be adversely affected by greater ranges of fluoride publicity. It additionally means that the prenatal nervous system could also be extra delicate to fluoride in comparison with that of school-aged youngsters.”

The findings had been groundbreaking, because the research, which spanned 12 years and acquired funding from the U.S. Nationwide Institutes of Well being (NIH), was one of many first and largest research wanting into this matter.

Prenatal Fluoride Publicity Is Linked to ADHD

The Canadian research on pregnant girls dwelling in fluoridated communities revealed ranges of fluoride just like these present in a research of pregnant girls dwelling in Mexico Metropolis, the place the chemical is added to desk salt. The identical Mexican pattern inhabitants has now been featured in one other research, linking fluoride publicity to ADHD.13

The research, which concerned greater than 200 mother-children pairs, discovered that greater ranges of fluoride publicity throughout being pregnant had been related to greater measures of ADHD, together with extra signs of inattention, within the youngsters at ages 6 to 12 years. “[The f]indings are in line with the rising physique of proof suggesting neurotoxicity of early-life publicity to fluoride,” researchers defined.14

It is also attainable that fluoride might contribute to or exacerbate behavioral issues akin to ADHD by means of pineal gland calcification. Regardless of its diminutive measurement, your pineal gland tends to build up vital quantities of fluoride, which ultimately causes it to calcify.

In addition to ADHD-like signs, pineal calcification can also play a job in Alzheimer’s and bipolar illness. In accordance with Frank Granett, director of medical pharmacy operations at Behavioral Middle of Michigan Psychiatric Hospital:15

“Situated deep inside the mind beneath the corpus callosum, which is the circuit connector for the fitting and left mind hemispheres, the pineal gland is liable for the secretion of melatonin, the human physique’s organic time-clock hormone regulating regular sleep patterns.

Extra importantly, the pineal gland performs a essential function within the enzyme pathway for the manufacturing of mind neurotransmitters together with serotonin and norepinephrine. Moreover, the physique’s antioxidant protection system is optimized by wholesome pineal tissue, which helps remove free-radical toxin accumulation within the physique.”

A overview in Lancet Neurology additionally categorized fluoride as considered one of solely 11 chemical compounds “recognized to trigger developmental neurotoxicity in human beings,”16 alongside different recognized neurotoxins akin to lead, methylmercury, arsenic and toluene. Among the many proposed mechanisms of hurt, research have proven fluoride can:17

Intrude with primary capabilities of nerve cells within the mind

Scale back nicotinic acetylcholine receptors

Scale back lipid content material within the mind

Injury the pineal gland by way of fluoride accumulation

Impair antioxidant protection techniques

Injury the hippocampus

Injury Purkinje cells

Improve uptake of aluminum, which has neurotoxic results

Encourage formation of beta-amyloid plaques (the basic mind abnormality in Alzheimer’s illness)

Exacerbate lesions induced by iodine deficiency

Improve manganese absorption, which has additionally been linked decrease IQ in youngsters

Impair thyroid perform, which might additionally have an effect on mind improvement

Can Fluoride Be Eliminated From Consuming Water?

Efficient 2015, the extent of fluoride in U.S. consuming water was diminished to 0.7 mg/L from a beforehand really useful vary of between 0.7 and 1.2 mg/L. If you happen to dwell within the U.S. and need to know fluoride ranges in your water, the Environmental Working Group’s (EWG) Faucet Water Database may also help.18 That is essential for everybody, however pregnant girls and households mixing method for infants ought to take further care to devour fluoride-free water. EWG notes:

“Even fluoride ranges of 0.7 ppm, the quantity of fluoride in consuming water really useful by the U.S. Public Well being Service, may end up in an excessive amount of fluoride for bottle-fed infants.

EWG recommends that caregivers combine child method with fluoride-free water. The Nationwide Toxicology Program is investigating the potential for low doses of fluoride to change thyroid perform and childhood mind improvement.”19

Sadly, fluoride is a really small molecule, making it tremendously troublesome to filter out as soon as added to your water provide. Any easy countertop carbon filter, like Brita, won’t take away it.

When you’ve got a home water carbon filtration system that has a big quantity of carbon, then it could scale back the fluoride as fluoride removing is in direct proportion to the quantity of fluoride and the time it is in touch with the media. It is simply not going to get all of it. Among the many more practical filtering techniques for fluoride removing are:

  • Reverse osmosis (RO). The downside is that it’ll take away many beneficial minerals and hint parts as effectively. RO techniques additionally want frequent cleansing to keep away from bacterial development. So, use a tankless RO system with a compressor
  • Water distillation, which, like RO, will get every little thing out, together with useful minerals. You then have to restructure the water
  • Bone char filters and biochar with activated charcoal

The only, only, most cost-effective technique is to not put fluoride within the water to start with.

Assist Finish the Apply of Fluoridation

There is no doubt about it: Fluoride shouldn’t be ingested. Even scientists from the EPA’s Nationwide Well being and Environmental Results Analysis Laboratory have categorized fluoride as a “chemical having substantial proof of developmental neurotoxicity.”

Moreover, in line with the CDC, 41 % of American adolescents now have dental fluorosis — unattractive discoloration and mottling of the enamel that point out overexposure to fluoride. Clearly, youngsters are being overexposed, and their well being and improvement put in jeopardy. Why? The one actual resolution is to cease the archaic follow of water fluoridation within the first place.

Luckily, the Fluoride Motion Community has a sport plan to END water fluoridation worldwide. Clear pure water is a prerequisite to optimum well being. Industrial chemical compounds, medicine, and different poisonous components actually don’t have any place in our water provides. So, please, shield your consuming water and help the fluoride-free motion by making a tax-deductible donation to the Fluoride Motion Community immediately.
