Utah becomes first US state to ban fluoride in its water

jiggawatts

I initially dismissed it as the same category of stupid as anti-vax beliefs, but it turns out that there are a decent amount of good studies showing a link between fluoride in water and (slightly) lower IQ when pregnant mothers ingest the fluoride. Note that there is no significant effect after birth.

The idea is to remove fluoride from water and advise pregnant women to use fluoride-free toothpaste.

Everyone else can get enough fluoride from modern toothpastes, or regular dentist treatments.

The logic is that fluoride in tap water made sense in the era before toothpaste had it, but now it is “overmedicating” a vulnerable fraction of the population.

culi

The IQ link is very heavily lacking in evidence.

In the actual research the main "risk" posed by flouridated water is actually fluorosis. This causes minerals in your enamel to be replaced with flouride which can cause them to be brittle in the long term. It's pretty uncommon but the thought is that now that flouride toothpaste are commonplace, the benefit of flouridated water is also way less. Which changes the calculus.

A not insignificant number of researchers are advocating for the view that flouridating water just isn't worth it anymore and the (slight) risk of flourosis is more significant than the (slight) benefit of decreased dental caries.

hedora

Children are the main group that benefits from fluoride in water because the fluoride helps strengthen teeth as they form. Lack of fluoride increases childhood cavities, leading to decreased academic performance.

This was a real problem in the San Jose school district until recently. They started fluoridation of water in the last ten years, and were the biggest US city that didn’t fluoridate. The evidence of the above is clear according to SJ dentists I have talked to.

somenameforme

The National Toxicology Program recently completed a fairly substantial meta study and concluded that "for every 1 mg/L increase in urinary fluoride, there is a decrease of 1.63 IQ points in children.". [1] This is also relevant to OP since it's not just pregnant women at risk from excessive fluoridation but also children. For now it seems that adults are, somewhat oddly, unaffected.

Fluorosis is very common afaik. My dentist told me I have it: slightly whiter patches on my teeth. Then he showed me his own fluorosis. It actually is stronger than the old enamel.

> The IQ link is very heavily lacking in evidence.

Where is the evidence that you have the authority to add 7mg/L of fluoride to my drinking water when I request the option? I get that it helps with cavities but me personally want the option to brush my teeth and drink basic water without additives.

crazygringo

What do you mean? There's literally tons of evidence. Do you think fluoride doesn't actually reduce cavities?

cratermoon

7mg/L? Where the heck did you get that figure? The correct value is a tenth of that: 0.7 milligrams per Liter (mg/L) The limit is 2mg/L, and that's only found in places with naturally occurring high levels of flouride.

loktarogar

The people of Flint, MI were (and some still are!) forced to drink bottled water for years when their water was contaminated with lead.

When you drink from publicly supplied water, you accept risks that can be much worse than fluoride in your water. If you want to avoid that, you need to procure your own drinking water.

don_neufeld

You can solve your “problem” for a very small price: it costs under $0.50 per day to distill your own drinking water per person.

So for $15/mo, “problem” solved.

Are you doing that?

Sparkle-san

It's not your water, it's municipal water you purchase with the fluoride in it.

afthonos

There isn’t any! GP doesn’t have that authority! Well done!

On the other hand, the society you live in probably has some sort of document establishing who does have the authority, and how it devolves to the actual policy-makers. Google “$YOUR_LOCATION government” and you’ll have some good starting points. If you’re lucky, you might even get to participate in the process; “$YOUR_LOCATION elections” will give you good pointers in that case.

Speedy218

> but now it is “overmedicating” a vulnerable fraction of the population.

Makes sense, but the intention also is that many people do not brush their teeth, or at least do not brush them as often as they should, and so fluoride is added to drinking water to compensate so people's teeth don't start to fall out at an alarming rate.

apothegm

Sadly, an alarming percentage of Americans don't drink water. I’ve spoken to way too many people who think water tastes wrong because it’s not sweet enough.

singpolyma3

I've heard this and it doesn't fit in my brain. They never drink water? Ever?

mjevans

Particularly when traveling, I don't enjoy the taste of tap water. Filtered or (factory filtered then) bottled... and I'm not alone in that viewpoint.

UltraSane

Wisconsin tap water tastes fine. Waco, Texas tap water is really nasty.

thayne

I bet those people drink fountain drinks, cofee, tea, etc. made from tapwater.

freehorse

Maybe instead of removing fluoride from the water they should add sweetener in there along with it /s

kelnos

I'm pretty sure that no amount of fluoridated water is going to save you if you do not brush your teeth.

Even if the fluoride somehow manages to overcome all that and prevent you from getting cavities, the gum disease will eventually cause all your teeth to fall out.

floriannn

> many people do not brush their teeth

many? (!!!)

Googling it all I found was one dentist website that said 2%, but didn't seem that reliable

kelnos

If that figure is for the US, then that's ~7M people. Feels like "many" to me.

dullcrisp

2% is definitely many

robbiep

The levels of fluoridation in order to cause difference in IQ as I understand it, from the Chinese studies, suggest that basically the effect if true occurs at around 2x+ the concentration found in supplemented water supplies.

My understanding also is that if you’re a dentist wanting to get rich, move somewhere that has unfluoridated water.

cortic

So if your training and double your water intake your basically lowering you IQ? (according to the Chinese studies) I wonder the method this uses.. has anyone looked at dementia rates in high fluoride areas.. Particularly in people with high water intake?

There is also a host of things we use water for from cooking to preserving, distilling and cooling.. i wonder if any of these things could concentrate the fluoride.

Also since fluoride has a lower boiling point any studies tracked what breathing in fluoride gas over long periods cause?

raincole

2x is basically no safe margin for something like water. Of course you can question the quality of the study, but if it's actually 2x, fluoride in tap water should be treated like lead pipes.

bigmadshoe

2x is honestly pretty small. I would expect the amount required to drop IQ to be larger by an order of magnitude or more to conclude that fluoridating water is totally safe.

unsupp0rted

> I initially dismissed it as the same category of stupid as anti-vax beliefs

Dismissing things out of hand like this is a category of stupid in itself.

Look at the current research, listen to people who devoted their careers to studying this, make up your own mind. If you're on HN, then you're qualified enough to at least figure out who the genuine experts are and read what they recommend.

Putting any science-based debate into a "category" to dismiss is turning yourself into one of the stupid people.

edanm

This is bad advice that no one could possibly follow.

> Look at the current research, listen to people who devoted their careers to studying this, make up your own mind.

Do you honestly do this with every single belief you have? Even every single controversial belief? Have you looked, yourself, into whether the world is flat? Whether the 9/11 conspiracy theories are true? Whether crop circles were created by aliens? These are all absurd conspiracy theories, but I assume most people don't know the "up to date" research on any of them, or what people who have "devote their careers" to research them say.

And those are incredibly common and well known to be false theories.

You have to take some things on faith to at least some degree - though to be clear, by "on faith" I mean "on faith of people you trust", which should really start with professional scientists etc. Also, it's totally fine to just say "I have no actual idea" about most things, and just go with what your current understanding of the status-quo position is.

unsupp0rted

Yes.

I think that link is only there when the fluoride levels are extremely high. See https://parentdata.org/fluoride-drinking-water/ for a good overview of the data

thayne

The advantage of putting it in water is that it ensures all children get it, not just the children whose parents can and do make sure they brush their teeth and go to the dentist.

syspec

So everyone else's kids have to have a lower IQ because of that?

Bad parents are gonna be bad parents.

mountainriver

Agree, my biggest issue is often where they source the fluoride and whether they test it. We found out in my (liberal) hometown that they were actually sourcing some derivative which has no human studies.

Given that everyone gets enough in toothpaste I just don’t see the reason to keep doing it, too much can go wrong. It’s kind of a strange mass medication that I’m not sure the government needs to be involved in.

someperson

What was the derivative?

windexh8er

> The idea is to remove fluoride from water and advise pregnant women to use fluoride-free toothpaste.

What most people don't understand here are the levels of fluoride being ingested. You can very easily remove all fluoride from your water with a relatively cheap RO system. But the recommendation to use "fluoride-free toothpaste" is just plain misinformation.

The reason is that you don't eat toothpaste. And even when adults ingest small amounts of toothpaste, again, the amount of fluoride is basically beyond negligible. Fluoride can both be applied to teeth as a varnish and/or consumed in drinking water. Using a flouride-free toothpaste can oftentimes do more damage than good because of SLS in those alternatives and because those alternatives often have abrasives that do far more harm than good. It's amazing people will recommend a product that may likely be worse because they have no domain expertise. So, yes, people should talk to their Dentist about these things and ask questions of them vs the Internet.

Really the downside to removing fluoride from city water is that low income families will be worse off with respect to dental related issues compared to more well off families that spend time instilling dental hygiene and preventative care for their kids. As you mentioned most people who have decent oral hygiene get enough flouride.

Where we live we have well water. Fluoride in the water isn't a concern, and if it was in our drinking water it generally wouldn't be consumed because of the water filtration anyway.

My anecdotal experience says that using fluride-free biomine toothpaste makes my tooth highly sensitive than using a good ol' Colgate. Now, I use it only twice or thrice per month randomly.

agentultra

That’s going to go poorly. A Canadian city removed fluoride from water in 2011 and reversed that decision 10 years later. There’s hard data on the effects and they’re not good [0].

[0] https://www.npr.org/2024/12/13/nx-s1-5224138/calgary-removed...

somenameforme

The study [1] that's based on seems pretty typical, and is precisely what drives skepticism towards these policies. The differences for permanent teeth were not significant. The paper claimed this may be because "7-year-olds have not had the time to accumulate enough permanent dentition caries experience for differences to have become apparent." The differences in temporary teeth had a deft (decay, extracted, filled teeth) of 66.1% in Calgary (no fluoride) and 54.3% in Edmonton (fluoridated).

So you're looking at a small positive improvements in dental outcomes, for what may be a permanent decline to IQ. That's obviously not a trade I think anybody would make, so the real issue is not whether or not it improves dental outcomes but whether it's having measurable effects on IQ as we have seen in other studies. [2] I don't understand why a study operating in good faith wouldn't also pursue this question in unison, or in fact as the primary question. I think relatively few people outright doubt the dental benefits of fluoride, but rather are concerned about the cost we may pay for such.

In the 2nd study that shows correlation between fluoride and lower IQ in children, the water had twice as much fluoride as the recommended amount in the US (1.5 mg/L vs 0.7 mg/L).

somenameforme

The only reason for lack of concrete statements on the 0.7 level was a lack of data, owing largely to US political culture (1.5 is the World Health Organization 'safe' limit). Not long ago fluoride stuff was considered a 'conspiracy theory' which greatly deters meaningful scientific research on the topic. This is in part because of social reasons (most people don't want to be perceived as 'fringe') and in part because it results in funding for such research drying up. For that matter even IQ studies themselves are borderline given the US political culture.

So for instance of the 19 low risk-of-bias studies, exactly 0 came from the US. 10 were in China, 3 were in Mexico, 2 in Canada, 3 in India, and 1 in Iran. 18 of those 19 studies found a significant reduction in IQ that corresponds strongly with increases in fluoride (the outlier was in Mexico). With the current administration we'll certainly be seeing funding for such studies in the US and so there should be much more high quality data on the 0.7 level forthcoming. But in general this is a major problem that needs solving. Exploring the breadths of science, including the fringes, should not require an activist political administration.

raincole

The most ridiculous part is that we have an alternative way to apply fluoride without intaking it. It's called toothpaste. But for some reason people act like Utah is banning vaccine.

SapporoChris

Using toothpaste with fluoride can be effective when used regularly as part of dental hygiene. What percentage of the population is going to do this? I've encountered grade school children who have never owned a toothbrush.

1970-01-01

Unfortunately, hard data is not acceptable. This is how it works for the current administration:

All previous data is ignored because of political reasons.

Teeth to slowly rot in heads.

Sometime in the 2030s, local voters will notice they have very bad teeth.

Locals will debate if adding fluoride is going to make teeth great again.

I don't think it's about hard data and optimization of health, but rather bodily autonomy.

I'm sure there are plenty of chemicals that could be forcibly put in the drinking supply that, based on current scient, would be beneficial for the public. But I would still be skeptical. Sell me these substances in my food or toothpaste, but don't put it in my drinking water by default.

It's also worth noting about 3% of western Europe has fluorinated so let's not pretend like this is unprecedented

fzeroracer

Many places in Europe have high levels of fluoride in their water naturally. In fact many of them are likely getting far too much fluoride.

Also realistically, if people cared about bodily autonomy cars would've been banned immediately thanks to the amount of particulates and local pollution produced causing far more adverse health effects.

bko

If a state wants to ban cars it should be free to do so. I think the benefits outweigh the costs and no one would choose to live there.

Also important to note no one is banning flouride. They're preventing it from being put in the drinking water. The equivalent would be if cars were distributed upon arriving to the state.

cherry_tree

Is one due the right to potable water at a tap at their home? Or is purified water a service offered by the government as one source of many available to the us population?

Are you not allowed to pay for bottled water instead of paying your local utility for drinking water?

The bodily autonomy argument seems bad to me because you are buying water from the government when you could buy water from any other source instead.

Is the argument that the government water is too convenient and so it should be unfiltered? Who is to say that filtering out poop is not infringing on my right to consume unfiltered water?

This is textbook whataboutism and seemingly an example of the nirvana fallacy too. All of the above as well as euthenasia and abortion can be included under bodily autonomy and there's no reason we shouldn't support all of it.

zamalek

Fluoride was introduced late enough in Zimbabwe that many of my childhood adults easily remembered life before it. There were many horror stories about the general state of teeth prior.

That being said, your dentist can apply fluoride to your teeth (boggles the mind why insurance won't pay the $50), and flouride toothpaste is still much more common than not. It's probably not needed in the water supply for dental purposes.

That being said, what are the other fringe benefits: such as microbe control?

grepfru_it

The city of Houston has stopped adding fluoride to water but allows natural fluoride levels to exist[0]. We are going on year 6 and the only thing we have noticed is harder water.

There is probably more nuance to both stories tho.

All the evidence in that article is based on what a politician thinks. "And I think another meta study came out also".

The actual high quality evidence shows that water fluorination has minimal impact on tooth health in 2025: https://www.cochrane.org/news/water-fluoridation-less-effect...

agentultra

I was thinking of this study:

https://onlinelibrary.wiley.com/doi/full/10.1111/cdoe.12215

Perhaps more could be done. The situation is complex because of several compounding factors for sure. There are European countries that have no water fluoridation and better oral health outcomes than in North America.

Regardless, there’s 10 years where a city in North America turned off water fluoridation and we have results of that decision to study.

oaktrout

I'm skimming the results, but it looks like adult teeth had less cavities when they turned the fluoride off...and that was not observed in Edmonton where they left the fluoride on the whole time.

"For all tooth surfaces among permanent teeth (Table 1a), there was a statistically significant decrease in Calgary, for the overall mean DMFS, which was not observed in Edmonton."

Based on their data, you could argue that fluoride increases cavities in adults... I'm not making that argument. I agree with you in that I think confounders are at play and the difference attributed to fluorinated water isn't as large.

People will use this study to take about the rampant tooth decay in Calgary, ignoring that there is roughly as much decay in Edmonton which had the fluoride on the whole time.

efitz

It is trivial today to get whatever level of fluoride is recommended for dental health, via toothpaste. So there is no compelling need to fluoridate as there exist viable alternatives to achieve the same that fluoridation is for any other purpose than dental health.

In the USA, dental care is not covered by public insurance, and is an optional add-on to insurance through one’s employer.

So without addressing at all whether fluoridation is effective or safe, there doesn’t seem to be any compelling need to fluoridate public water, and there’s no economic down side for the public if governments choose not to do so.

Given this, why not just leave people alone to make their own choices? If the citizens in a city or state want to fluoridate the public water supply, then do so; if they choose not to, then leave them alone. It’s a free country and voters are grownups; let them choose for themselves.

If you live in a place that chooses the choice you dislike but for some reason fluoridated public water supply is a critical issue for you, either campaign to change it or vote with your feet.

This issue just doesn’t seem important enough to me to spend any effort arguing either way.

karaterobot

> This issue just doesn’t seem important enough to me to spend any effort arguing either way.

Your comment is well-stated, and in the spirit of a free and liberal society. The problem—not with your argument, but with the world—is that today there seems to be literally no issue unimportant enough not to argue about, or use as the battlefield for an unending ideological proxy war. My guess is that few of the people arguing this issue on HN have strong feelings about flouride qua flouride, but have strong feelings about the kinds of people they believe oppose or support the use of flouride in water, and this notion is what they're really railing against.

HEmanZ

This rings true for my gut reaction. The family and acquaintances in my life who have been up in arms against fluoride for years now are actual neo nzs (like “deport all non whites”, “you-know-who controls america”, “superiority of the white race” level).

So my instinct is to really be afraid of this anti-fluoride wave, even tho practically I don’t care one way or another.

nozzlegear

I think one thing you're not considering (especially when you say we should vote with our feet) is poverty. It’s true that fluoride toothpaste is widely available, but for people in poverty, of which there are millions in our country, basic hygiene items like toothpaste and a toothbrush aren’t guaranteed. Neither is it guaranteed that everyone has a perfect daily brushing habit like the dentist tells us; there are people who don't brush every day, or even every week.

You talked about dental care not being covered by public insurance — is it not worth considering that some basic level of dental care is already being applied to the country via fluoridation? It's a minimal, cost-effective way to prevent tooth decay at scale. Fluoridated water is one of the few dental protections available to everyone regardless of their income.

kelnos

If you're not brushing your teeth, periodontitis will get you; the resulting bone decay will cause your teeth will fall out. But sure, great, the water was fluoridated, so I guess it's nice that those now-missing teeth are free of caries?

iamtheworstdev

there are people who own a toothbrush but do not purchase toothpaste. money is not something everyone has and when you start having to choose between certain things, tough choices get made.

nozzlegear

I really don't feel like you're interpreting my comment in good faith. Do you really think I was arguing that poor people literally never brush their teeth, and every single poor person in the country will eventually suffer from periodontitis? If you read my comment again, I'm sure you could find a way to engage in better faith.

wtcactus

I don't believe there's a single person in the USA that's so poor they can't pay $3 for toothpaste every 3 months. I also believe that having such a low personal hygiene where you don't brush your teeth altogether, even if you drink water with fluoride, will have terrible results anyway for your teeth anyway.

I'm completely sure that any people that don't brush their teeth is just because they are too lazy to even bother.

This trope of justifying everything with "but there are millions of poor people in the USA" is really tiresome.

akutlay

It's not that they can't afford a $3 toothpaste, it is the environment they are in that makes it hard to prioritize things like this. It is the education and the overall life quality (or the lack there of) that causes this problem.

Whatever the number is it's not appropriate for the state to medically intervene on their behalf.

Sadly people that don’t brush are probably not drinking plain water either.

preisschild

Thats not really true. I had problems brushing during my childhood, because most toothpastes triggered my gag reflex, but I mostly drank tap water.

ModernMech

Trivial is what we have now. Taking fluoride from the water means people will have to spend extra time and money on fluoride and dental treatments. When I viewed it, your comment appeared directly after this one (https://news.ycombinator.com/item?id=43524171), which talks about a town in Canada that voted to abandon fluoride , saw worse health outcomes, and then voted to reinstate it. This tells us that fluoride is not trivially available to people, and taking it away from them enriches corporations while making people less healthy.

efitz

So you’re saying that forcing a treatment on people that don’t want it, is a fair price to pay to reduce inconvenience for others?

I’m not sure what your anecdote proves because I’m wholly in support of a polity being able to make that decision.

ModernMech

I was responding to this point:

  It is trivial today to get whatever level of fluoride is recommended for dental health, via toothpaste. So there is no compelling need to fluoridate as there exist viable alternatives to achieve the same that fluoridation is for any other purpose than dental health.
I also agree that people should be able to make decisions like this, but they should be aware that one of the results of these kinds of efforts could be that everyone gets less healthy, rather than everyone stays at the same level of health with less cost.

Presumably when they voted to get rid of fluoride in the water in Calgary, they didn't do so expecting the outcome would be that people in their town would be less healthy overall. Nonetheless, that was the outcome of their vote.

The anecdote shows that it's not trivial, because when the fluoride in the water went away, people were not able to trivially replace it, leading to worse health outcomes. Ultimately people found too high of a cost, seeing as that they reversed the decision.

Sadly it took a decade for them to realize their mistake. I worry people today are making the same mistake, and we will reverse it in a decade after health outcomes are shown to have worsened.

In general it's some weird relic of medieval view on dentists not being medical professionals but someone akin to barbers. It shouldn't exits but it persists.

Yeah, this is one of those places where because RFK Jr took the anti- stand there's an understandable assumption that it's more nutty anti-science stuff, but it's much less clear cut when it comes to fluoridation.

Maken

Fluoridated water was already a plot point in Kubrick's Strangelove from 1964.

Using certain family members as a personal rubric, fluoridated water has been a right-left issue for at least 2.5 decades. I think it’s been pretty polarized for longer, though it may have taken a long time to gain steam in mainstream “discourse”.

jemmyw

I was surprised to learn this. "Worldwide, the Irish Republic, Singapore and New Zealand are the only countries which implement mandatory water fluoridation."

I live in New Zealand and my town doesn't put fluoride in the water but it seems like they'll be made to do so fairly soon. I don't really care one way or the other from the point of view of ingesting the stuff, but I do consider it a bit of a waste of money. People who brush with toothpaste don't need this and people who don't are probably drinking too much soda. A more useful thing to do might be to subsidize toothpaste for people who can't / won't buy it for their kids.

fao_

> People who brush with toothpaste don't need this and people who don't are probably drinking too much soda

I think every person in my social circles with any kind of illness or disability would be incredibly grateful for fluoridation, and it's not because of drinking too much soda

habosa

Many other places fluoridate salt. There’s many ways to get flourish (toothpaste being the best if you can get people to use it correctly) but the evidence that mass fluoridation of some kind is good for dental health is enormous.

EasyMark

It seems like they could compare states/countries/cities while controlling for other factors (age, income level, etc) to see how well fluoridation works. I'm pretty sure you'll find that fluoridation helps lower the number of cavities, but it's not going to be a slam dunk.

AndrewSwift

People who want to remove fluoride from the water should visit countries where fluoride is not added and look at people's teeth.

I live in France and it's just so obvious that people grew up without fluoride — even celebrities try to talk without showing their teeth when they're on TV!

I'm all for getting consent in most cases, but sometimes you'd have to be an idiot not to take the obvious win.

It's like we were delivering flakes of gold with the mail and people complained — that's not what mailboxes are for!

abxyz

You're misattributing: the U.S. has a perfect white teeth culture that doesn't exist elsewhere. Many people outside of the U.S. have healthier but uglier teeth. Fluoride isn't the reason for good/bad teeth inside/outside of the U.S, it's cultural. Many places outside of the U.S. do put fluoride in their water (nationally or regionally) and have "bad" teeth (e.g: England).

blitzar

People in the U.S. don't have perfect white teeth, they have are cosmetic procedures on their teeth equivalent to liposuction, silicone, botox, hair plugs and/or laminated face.

People don't bleach their teeth much outside the US as far as I know. You can see it especially well with US actors, their teeth looking like the someone photoshopped them to #FFFFFF

JeremyNT

Others note the bleaching, which is relatively low cost, but the (purely cosmetic) straightening is probably the more interesting example.

People in the US pay a lot of money to have very straight teeth. You can see this clearly with American celebrities and actors (versus European counterparts), but the culture of cosmetically modifying teeth is very strong all across "middle class" and up America as well.

Way more people having their teeth whitened? Braces being more popular.

Bleaching your teeth, specifically.

bobbylarrybobby

While tooth whiteness in the US is often divorced from tooth health, fluoride does add a yellowish tint to your teeth, so the healthiest teeth — those imbued with fluoride — are slightly yellow. (In fact when they first decided to add fluoride to water, one of the questions was just how much they could add before your teeth would turn completely yellow. Health-wise the yellowing was fine, but it was obviously visually unappealing.) Ugly teeth may be due to poor/lack of orthodontia, but it's probably not due to better dental care.

But flakes of gold are not associated with a lower IQ in children.

"The NTP monograph concluded, with moderate confidence, that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children."

https://ntp.niehs.nih.gov/whatwestudy/assessments/noncancer/...

So it is also not clear, if the lower concentration typically found also has this effect.

"It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ."

But the solution of just using (cheap) Fluor in toothpaste to apply the Flour where it should go - to the teeth and not the stomach, sounds smarter to me.

kelnos

So in other words, 0.7mg/L fluoridated water is also not associated with lower IQ in children. That study did not prove it safe, but it did prove it unsafe, either.

lukan

That study did prove, that too much flouride is not good for intelligence.

And there are other sources besides water from the tap, so I don't think it is intelligent to raise the base level, when the option of local applying exists. What is wrong with toothpaste?

eigart

Where I live, dental health is good and we don’t have fluorides in the water (we have free, mandatory dental care for children). We recently banned the use of fluorides to make our skis go fast because of the environmental impact.

Ok, but then you just say, we have enough naturally occurring fluoride. Adding more is just a waste of money.

Or, toothpaste has enough extra fluoride, adding it to water is just a waste of money.

This is not that. This is the US health system being lead by a bunch of woo-woo people who don’t understand how research works.

adrr

I am saying it’s weird to fluoridate water in areas with high levels of naturally occurring fluoride. Also to point out that there is naturally occurring fluoride. If Utah believed fluoride was a health risk, why aren’t they spending tens of millions to filter it out. Or is it just virtue signaling.

lurk2

> This is the US health system being lead by a bunch of woo-woo people who don’t understand how research works.

The majority of the developed world does not fluoridate their water supply. The US has one of the highest rates of fluoridation in the developed world. Within America, fluoridation rates are highest on the East Coast and in the South, and lowest on the Left Coast.

adrr

There’s also fluoride salt added to table salt that is widely used to accomplish the same thing as fluoridating water.

https://www.acffglobal.org/salt-fluoridation/

starfezzy

The people leading the health system are highly credentialed. Moreover, highly credentialed people, in medicine as in all fields, frequently disagree on what studies show, how valid a study is, what it's flaws and limits are, how conclusive it is, and so forth. And the consensus has a long, time honored tradition of being wrong from time to time.

Ultimately, the woo woo people are the ones who rely on someone in a labcoat to tell them whether ingesting government approved (there's your first red flag) synthetic fluoride from industrial byproducts is "necessary".

If it's useful, brushing it onto your teeth and into your gums 56,000 times in your life is probably sufficient, particularly given that we don't know with absolute certainty beyond any shadow of a doubt that the industrial waste options are totally without health consequences. I'll literally just take care of my teeth and cross my fingers over listening to modern medical consensus on a range of topics where I simply trust intuition and common sense more.

driverdan

That's not how it works. There is an ideal amount of fluoride. If the natural amount is lower more is added. If it's higher the extra is removed.

cladopa

For me as a European, adding fluoride to water for your teeth is as ridiculous as cutting the foreskin of babies' penis in name of (dubious) "hygienic reasons".

But people get used to it. Specially when they don't get to experience the alternative. Most people rationalise it is a good thing. Stockholm syndrome.

stevebmark

Which part of Europe are you in? Countries in Europe add fluoride to water, salt, milk, and Italy has naturally fluoridated water.

> The European Academy of Pediatric Dentistry (EAPD) recently called water fluoridation "a core component of oral health policy" and adds that salt fluoridation "is suggested when water fluoridation cannot be implemented" due to technical, logistical or political reasons.

Preventing cavities is far more effective with topical application of fluoride on the teeth, rather than ingestion.

I personally don’t buy the passive health benefit. Even if it’s true, there’s no proof that fluoridated water is superior to topical application.

Not to mention that if we’re going to just roll over and accept stuff in the water for public health reasons, what really should be added are more vitamins, not fluoride. In particular vitamin D

nemo44x

For children developing their “adult teeth” fluoride ingestion strengthens those teeth before they pop out. Topical has no effect obviously since they haven’t surfaced yet.

amazingamazing

And for that there is fluoride mouthwash, which again isn’t ingested and would be more effective.

Putting fluoride in water promotes freedom. That sounds crazy, but let me justify it.

If you are poor you can't go anywhere or buy anything. You're not free if you're poor. If you are sick, you may be confined to a hospital bed or not feel good enough to do anything. If you are sick you're not free.

Putting fluoride in water reduces dental costs and incidence of cavities and therefore tooth infections, particularly among societies poorest. Therefore, due to fluoridation in water some people are less sick and have more money and therefore are more free.

The contrasting view is that putting fluoride in water is literally medicating people without their affirmative consent. It is the government forcing you to take a medication. It is coercive and therefore an attack on your freedom to not take medication. It is the government interfering in your life.

The contrast between positive freedom, the freedom to do something, and negative freedom, the freedom from interference in your life, is the core political argument in America right now. Negative freedom, freedom from government interference, is being promoted by those seeking to weaken the government enough to supplant it. People who are poor and sick are likely unable to stand up for themselves or participate in solidarity against authority. This individual issue is relatively small, but you take 100's of issues like this, and the effect is to create a class of people who aren't able to do anything but be obedient workers.

shireboy

This take has a few problems: Poor people in the US are capable of using fluoride toothpaste and flossing. At least at homeless shelters at outreach things I’ve been to, toothpaste and toothbrushes are freely available. Your argument hinges on them being incapable on the whole and needing a Benevolent But Superior Intelligence to provide an alternative for them.

Second, it completely ignores any debate over effectiveness or side effects. It could well be that fluoride in water is great for teeth but bad for brains. The objections to fluoride in water I’ve seen are more along those lines. Im not clear the validity of those claims but for example anti fluoride advocates don’t typically object to chlorine in water to kill germs. That seems the core issue- without bias from stakeholders, is the benefit of fluoride proven and the risks disproven? It’s hard to answer because a study needs to span many years and exclude many variables.

And in general I think that is what needs to happen with these type debates. Take them _out_ of the sphere of charged political opinion and focus on getting to the objective truth of risks and benefits, then be transparent. People can handle “here are the known pros and cons and what we think that means” over “there are only pros and no cons and if you disagree you hate poor people”

No, it's not hard to answer, because all those studies have been done and the results were that fluoride is safe.

What needs to stop happening is people ignoring objective reality just because the results happen to align with the other "team's" position on something.

"Out of a population of about three-quarters of a billion, under 14 million people (approximately 2%) in Europe receive artificially-fluoridated water."

The problem I continually see in the USA is the ascription of differences of opinion on [any topic] to America's Great Divide between enlightenment and barbarism. I find it often helpful to just check, what do these policies look like outside of America? It doesn't mean Europe got it right on fluoride, it just suggests against adopting the framing that your POV is 100% objective reality proven beyond doubt by Science™ and no rational person not in the throes of "own the [other team]" bad faith might disagree.

mdorazio

I'm not saying you're wrong, but you made multiple strong claims without a single citation or study link. We could have a better conversation with data to look at. There's a decent (though somewhat biased) review of the debate in [1]. It's worth noting that if you read the linked studies there closely you'll find the truth is, as usual, nuanced. Specifically, that "fluoridation is a population-level caries preventive strategy" [which may or may not be effective at the individual or small community level due to other factors]. I.e., good at the national level for statistically significant reduction of tooth disease incidence, but at less-aggregated levels the confounding factors like diet and how often/well people brush their teeth are going to be bigger determinants of efficacy.

It's also worth nothing that 1) over-fluoridation is pretty bad and can affect poor or malnourished communities (ex, [2]); and 2) there are alternatives to fluoride that may be equally effective with fewer risks at higher concentrations (ex. nano hydroxyapatite).

> Thoroughly scientifically debunked. Repeatedly, over decades.

"The NTP monograph concluded, with moderate confidence, that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children"

This is from an NIH meta-analysis. Its a pretty rigorous study.

https://ntp.niehs.nih.gov/whatwestudy/assessments/noncancer/...

"It is important to note that there were insufficient data to determine if the low fluoride level of 0.7 mg/L currently recommended for U.S. community water supplies has a negative effect on children’s IQ"

This is why there's such a fierce debate. Based on the most recent scientific literature there seems to be evidence of a dose-dependent effect of fluorine levels in water and lowered IQ in children, meaning it has some kind of neurotoxic effect. But we don't have robust evidence to say 0.7 mg/L has a similar effect. That doesn't mean it is DEFINITELY safe, it just means more research needs to be done and the current research that does cover the 0.7 mg/L range may not reach statistical significance.

The fact though the NIH suggests 1.5mg/L is likely unsafe, which is only 2x what America's tap water contains, I would not blame people for being uneasy about. It is often the case the that the FDA regulates food additives that have potential negative side effects to be limited to concentrations 10x lower than what is seen as unsafe.

I am not suggesting it's a straightforward choice to defluorinate water, but I see people often repeating claims like you have that dangers of fluoride are "thoroughly debunked" and that's simply not true. I don't blame people for having that sentiment either, because 0.7mg/L is seemingly still considered safe, and some of the loudest advocates of defluorination have no shortage of thoroughly debunked crazy views on things (possibly due to brains half eaten by worms). It makes it very easy to brush off the skepticism.

But it's also important to keep in mind science is built on the premise that one must be ready to re-evaluate past assumptions when new data arises, and generally speaking the new data around fluoride I hate to say seems to show there is indeed smoke.

It's also the case that when the US initially fluorinated water supplies it was a massive public health success, but these days it seems to make a much lower impact now that fluoride toothpaste use is ubiquitous (plus the levels were lowered from 1.0mg/L in the 70s, likely reducing its overall effectiveness). It is IMO both very reasonable to fund more research into this to know conclusively if 0.7mg/L is indeed safe, and also consider public health policy that focuses on promoting dental hygiene through other means in places that do defluorinate.

I do not agree with Utah's decision here mostly because it seems to neglect that defluorination will create a void that requires other public health policy efforts to fill it, poorer and less educated communities will suffer unless government led efforts to promote and make dental hygine affordable are not also undertaken.

cjbgkagh

While I would like to think that I have gotten a lot smarter in the last 20 years it seems more likely that other people have on average gotten a lot dumber.

While I’m sure there are many causes I’m of the opinion that no stone should remain unturned when looking for answers. Fluorine in water has a viable alternative (toothpaste that is spit out) so out of an abundance of caution my preference is for unflurinated water. In my past life as an applied researcher I have learned to be rather distrustful of academia and the ‘science’ that is produced, ‘fruit from a poisonous tree’.

oaktrout

The conclusion from the largest and strongest studyies is that there is a certain level of fluoride that harms IQ: https://ntp.niehs.nih.gov/whatwestudy/assessments/noncancer/....

"The NTP monograph concluded, with moderate confidence, that higher levels of fluoride exposure, such as drinking water containing more than 1.5 milligrams of fluoride per liter, are associated with lower IQ in children"

They found fluoride in drinking water concentrations was associated with lower IQ, the opposite of your claim of "proven safe".

Show us some evidence that is proven safe, so far as I can tell all evidence points to unsafe or "we're not sure".

> What needs to stop happening is people ignoring objective reality just because the results happen to align with the other "team's" position on something.

I couldn't agree more. The study that is cited above started when Obama was president by the way.

jeffbee

> Except it's not—fluoride in the drinking water concentrations is proven safe and it doesn't affect brains.

What's amazing is these anti-science wackos are rejecting the largest-scale experiment of all time, with the best evidence that anyone is ever going to have on the subject. We have both temporal and spatial boundary conditions with and without community water fluoridation, where a large population has it and another large population doesn't have it. There is no evidence that the without-fluoridation population has higher intelligence! There is a huge body of evidence that the people without fluoridation have more decayed teeth.

jongjong

> fluoride in the drinking water concentrations is proven safe and it doesn't affect brains.

We can never be sure who funded the studies and whether or not the results can be trusted. Studies have shown that studies cannot be trusted. I err on the side of caution.

You're welcome to put it in your own drinking water if you trust the studies.

> What needs to stop happening is people ignoring objective reality just because the results happen to align with the other "team's" position on something.

Nobody can perceive objective reality. Everyone is delusional concerning just about everything. The people who think they know what's going on, are most delusional of all.

Dark times are ahead, I'm afraid, and people's trust-meters are going to be valuable again.

"Findings: Despite differences in exposure and outcome measures and risk of bias across studies, and when using group-level and individual-level exposure estimates, this systematic review and meta-analysis of 74 cross-sectional and prospective cohort studies found significant inverse associations between fluoride exposure and children’s IQ scores. [...]"

Maybe you should reconsider that what you heard once was the definite truth.

hayst4ck

Truth and even the idea that there is objective truth is a fundamentally political concept. Authoritarians are opposed to the idea of objective truth because objective truth gives a person a foundation on which to criticize and dissent from those in power. Truth is threatening to authoritarians. Truth is an alternative source of legitimacy.

We are experiencing an assault on objective truth in the US in order to get scientific institutions to submit to political authority rather than the authority of reason.

So I agree with you, it is policy that should not be handled by politicians but by experts, which none of us are. Unfortunately science is being politicized.

The problem is science challenges those who derive power from means other than reason.

Defending scientific consensus is seen as an equally political act as denying it.

hilbert42

"The problem is science challenges those who derive power from means other than reason."

There's been a fundamental shift away from science in the last fifty years or so. Some is understandable—chemical pollution, etc. which is unreasonably blamed on science instead of industry's bad behavior—but there's another thread running here and it's an anti-establishment one.

The question I can't fully put a measure on is why nowadays so many people automatically reject anything that's mandated by government even when they'll benefit from that mandate. The fluoride debate is somewhat akin to the vaccination one, rather than weighing up the comparatively minor risks versus overwhelmingly beneficial outcomes of those mandates they'll simply reject them outright.

That doesn't make much sense to me.

I don’t agree with the framing of “we are experiencing an assault on objective truth…”.

We are experiencing a challenge to some existing status quo practices, some of which have come out of science in the past.

But nowhere in any conversation has the dialog been “we must question status quo institutional knowledge, and objective truth, to dismantle the institution”. (That’s left speak, actually, and I am acutely aware of leftist circles where that is the conversation.)

Look at RFK Jr. This guy doesn't need power and control. He’s a whacko with some different beliefs about health—who fundamentally believes he’s making humans safer because of his negative lived experience with health policy in the US.

Occam's razor points to there being a credible benign reason for him to be motivated to challenge existing policy. (And if there is one area of science ripe for iteration, it’s nutritional health.) We don’t need to grab for more extreme alarmist narratives to explain what’s happening.

It simply doesn't take some autocratic utopian agenda to question whether fluoride is worth it and advocate for political change.

It’s honestly really disingenuous and disheartening to hear people towing this “the right is trying to dismantle the fabric of western liberal democracy and install fascism” line.

travisgriggs

scarface_74

It’s even worse than that. People aren’t even voting for their own self interest. The people in the poorest states and in poor counties in richer states in the United States are consistently voting against universal healthcare, affordable post high school education and are cheering the government taking away services that they depend on the most.

There are two basic categories of causes.

The first is being pure anti science - anti vaccine, anti fluoride, etc

The second is they are more concerned about “God and guns”, immigrants, and the demographic shifts in the US than their own interest.

This is so incurious. Obviously most people, poor or not, have access to fluoridated toothpaste and toothbrushes, and can brush.

Yet OP cites data (not explicitly, but you can start here: https://pmc.ncbi.nlm.nih.gov/articles/PMC6974062/, there are many like it).

Fluoridated water makes the most impact on poor and undeserved communities: Why?

Is it because poor people are less capable of brushing or have less access to fluoridated toothpaste?

Is it because poor people are poor because they have poor self control, which prevents them from regular brushing?

Does it matter? Nothing hinges on them being incapable at all - your conjecture can be as uncharitable - poor people are dirty and incapable - or charitable - poor people have less money and time to seek dental care, have higher rates of untreated mental and physical illness i.e. ADHD, disabilities that interrupt daily tooth-brushing routine - as you want.

But the result is still that if we want children from poor families to have less cavities by the time they reach adulthood - we should fluoridate the water! If you trust the western medical establishment, it's broadly safe. If you don't, then none of the evidence above matters to you anyways.

uppost

You're close but still a bit strawmanny. If we want poor kids to have better dental outcomes we should do more than just flouridate. We should find out why the poor have worse dental outcomes and address the root problem(s), which I would imagine in the US is something like soda consumption or lack of dentists in poor areas.

yalogin

See this is the problem today. Just because some one doesn’t know doesn’t make it non existent. We have decades of studies and evidence that fluoride is good and has no side effects, but the detractors ignore all of it and keep nullifying all that knowledge. Now they are successful too. In a society where everyone wants the whole boat to rise up, we need a certain amount of honesty and integrity and sadly these arguments don’t have it

hedora

> Poor people in the US are capable of using fluoride toothpaste and flossing

This is absolutely not a substitute for fluoride in drinking water, which is most important for kids. When your teeth are forming below the gumline, the fluoride you ingest strengthens them. Brushing gums with fluoride doesn’t help.

Objective truth isn't something you can know, but it's a destination that must exist for pursuit of knowledge/curiosity to have any meaning.

With contradictions you know what is not true, and through knowing what is not true, you can approach what is true. Truth is expressed in consistency, not completeness.

That's why anyone should be extremely suspicious of anyone who is not, or doesn't care about, being internally consistent.

Adding fluoride to water was revolutionary in the 1940s, but its benefits have significantly declined since fluoride toothpaste became common in the 1970s. While fluoridation made sense when products containing fluoride weren't widely available, it is much less effective and necessary now. Sure, some countries and communities may still see benefits from it, but widespread fluoridation doesn't seem necessary in many parts of the world.

Perenti

Not true. Every time I see a dentist here in Queensland (non-fluoridated water) he asks me where else I lived as my teeth are so much better than what he usually sees, and if drilling my teeth are much harder than most Queenslanders.

My early years were spent in Melbourne, where fluoridation was introduced around 1970. That's the only time I lived with fluoridated water, for about 3 years. yet dentists can see the effects 50+ years later.

I don't use a toothbrush or toothpaste, and haven't ever really, as my ASD makes it unbearable.

impossiblefork

But you will brush your teeth anyway, and then you apply fluoride topically. It works.

Here in Sweden we decided against fluoride for this reason and the fact that it is in fact toxic. It isn't sensible to use systemic exposure when we can use topical exposure and can improve mouth health by education, so that people do what they're supposed to.

The fluoride approach achieves a basic level of health, but you can do so much better.

imacomputertoo

Fluoride is not "in fact toxic". A substance becomes toxic in high amounts. Vitamin D becomes toxic in high amounts. The level of fluoride in drinking water is well below the toxic level.

I really don't agree with that Paracelsian view. Some substances are Paracelsian, other are like lead, and I'd place fluorides in-between these two, a neither fully Paracelsian or non-Paracelsian poison.

Somewhat related, as a teen in the 90s I worked at McDonald’s in The Netherlands. Because of the diet in the US, the bread used for hamburgers contained extra calcium to be more ‘healthy’, because many people did not get enough calcium intake. In The Netherlands, where people drink much more dairy products, especially back in the 90s, people would get plenty of calcium so there was no need to put extra in the bread. But because a hamburger should be a hamburger no matter where you buy it worldwide, the Dutch McDonald’s hamburger bread still had the added calcium

You have to drink 32 ounces of milk per day to get enough daily calcium.

graemep

In the UK at least some areas have fluoridated water, despite almost all toothpaste being fluoridated. I suppose it most benefits the minority of people who do not brush their teeth. That benefit has to be balanced[1] against some evidence of risk.

IMO the right fix is better dental hygiene, and a better (less sugary) diet. These are in turn are in part symptomatic of other problems (poverty, long working hours with regards to lack of supervision of children).

There a really unfortunate use of "significant" in that document. The scientific meaning and the general meaning will cause very different interpretations from laymen.

"Here in Sweden we decided against fluoride for this reason and the fact that it is in fact toxic."

All water collected from natural sources contains some level of fluoride and other salts (which varies greatly from place to place). Does then your local water authority remove these naturally-acquired chemicals?

impossiblefork

Generally not, but we choose where we take our from water from.

If there's too much fluoride in the rock water we take soil or surface water instead, for example. If there's too much fluoride in the water we do not supply it to people's taps, but this is for values like 4 mg/L.

So we mostly don't take any measures. In Stockholm it's apparently less than 0.2 mg/L though.

zouhair

Just an FYI, water is also toxic.

abrookewood

Yes, I was going to mention this. Had a friend who went down the coast for a day trip with a bunch of mates. On the way back on the train (1.5 hour ride) they had a competition to see who could drink the most water and most of them had several litres, a few of them managed a bit more. My mate also had a bunch of chips/snacks, but not everyone did.

Later that night, he got a desperate phone from his friends mum, screaming at him "What did you take! What drugs did you take!!!", he replied that they hadn't taken anything, but wasn't really believed. His friend was rushed to hospital with severe seizures and convulsions. The doctors eventually put him on a saline drip and he recovered.

Basically his friend lowered the salt content in his body so much that his body could not pass electrical signals. My friend was fine because he had consumed a bit of salt in his snacks. Kinda crazy.

> But you will brush your teeth anyway, and then you apply fluoride topically. It works.

Relatively few of the poor have the disposable income, time, education, and long-term worldview needed to reliably do that.

EDIT: This comment is about America's poor. Though the same applies in much of the world.

impossiblefork

Your GDP per capita is 50% higher than ours. You have money for this.

If there's no will to raise up the poor, you it should be straightforward to use the state directly to ensure that everyone is taught how to brush their teeth and ensured to have access to brushes and toothpaste.

NomDePlum

I agree with this in an American context. In Sweden, it will be much less true. This difference can also however be attributed to government "interference" with higher taxation supporting better social care for those at the poorer end of the scale.

Freedom comes at a cost, the US and Sweden are paying that cost in different ways.

Freedom from is the American way.

Freedom to is the Canadian way.

That's why Canada becoming an American anything is ridiculous and pisses off Canada so much that, for example, we've reduced our flights to America by +70% over the coming months.

usrusr

Not when it comes to religion though: the European way (and I feel very much like considering Canadians something like honorary Europeans these days) was forged in painful wars stemming from and fueled by influence of religion on politics, and abuse of religion by politics. Both on the collective level, not so much on the individual level. The European way is all about having a strong firewall between religion and politics, to keep the former out of the later. Freedom from.

The American way is completely devoid of that concept. It's all built on that Pilgrim Fathers founding myth and only ever cares about keeping the state from getting in the way of individual beliefs. It's so focused on that part and only that part that even an almost-all-out theocracy would be fine as long as it did not mess with individual beliefs. "Freedom to" without the tiniest trace of "freedom from".

Ruphin

This is factually incorrect. Even though in most European countries there is a formal separation of religion and state, there is nothing that "forbids" any political party from having a strong religious affiliation. In fact, in nearly every European country there are major political parties with a strong Christian affiliation. See: https://en.wikipedia.org/wiki/Christian_democracy

There are even countries which have political parties that are Islamic affiliated.

The separation between religion and state refers to two things: the state not being able to enforce any religious aspects on citizens (freedom TO exercise any religion without interference from government), and religious entities not being able to influence or pressure the government outside the electoral process (freedom TO govern without interference from religious entities). Neither of these things prevents a political party founded on religious beliefs to participate in the electoral process.

Y_Y

> The European way is all about having a strong firewall between religion and politics

I find this quite contrary to my experience of e.g. modern Germany, Spain, Poland, Italy where many politicians are explicitly religious, laws are written with majority religious affiliation in mind, religious taxes may still be levied. Even France still feels in many ways like a "catholic country", even if they do have good explicit separation of church and state.

I would have said that government and (Christian) religion are completely inextricable for most Europeans, even if the majority of the population isn't seriously devout or even practicing.

Canada does the opposite of America even if it hurts Canada - it’s a part of its identity.

Redefining freedom as “forcing something on people for their own good” is not how anyone actually defines freedom.

It’s like saying children have the most freedom because their parents force them to do things that will benefit them.

jclulow

> Canada does the opposite of America even if it hurts Canada - it’s a part of its identity.

As a duel citizen of the US and another Commonwealth nation, I have to say that this is exactly the ridiculous self-caricature perspective that gives foreign nationals a sort of combination of pity and contempt for the average US citizen.

While it's true that your cartoonish portrayal of freedom is one possible interpretation, there are most certainly others, many of which present citizens with actual measurable freedoms that they would not enjoy in the US.

For instance, Australians have, since the late 1990s, been relatively free of mass shootings, especially in schools or other public areas. Because the police are allowed to force you to take a random breathalyser test without probable cause, we are generally substantially freer of drunk driving. Because we have a social safety net, people are free from the need to opt out of life saving surgery because they fear the abject economic violence that the US visits upon the "uninsured".

On the other hand, the US has substantially more sensible libel laws than most Commonwealth countries. These things can cut both ways, but it would be a mistake to interpret other countries as attempting a childish breath holding exercise just to differentiate themselves from the hip and cool nation.

kvdveer

"freedom from", you will not be given a prevention from some horrible disease. You can buy it if you can afford it, but a significant portion of the population can't, and some of them will not be able to enjoy life because of it.

"freedom to", a prevention will be provided. You can always decide to take alternatives, if you can afford it. A significant portion of the population can't. They will be able to enjoy life.

Equating freedom with the liberties the rich have is absurd. In any society, the rich will have the most freedom, even in the most oppressive ones. The true litmus test for freedom is seeing the freedoms the poor can enjoy. By that standard, the US doesn't score very well.

karparov

As a European who has lived in both countries I can only laugh at this. From our perspective, US and Canada are 99% identical, culturally.

hilbert42

So then, you'd also be against adding folate/folic acid to bread for the same reason?

For those who don't know many countries including the US mandate the inclusion of folic acid in bread and certain other foods to ensure pregnant women get enough. A deficiency of folic acid during pregnancy causes birth defects in infants. https://en.m.wikipedia.org/wiki/Folate

aziaziazi

I never heard of that supplement (not a father) and was very surprised to find 80 countries mandate it. I checked the list (below) and it turns out the 80 countries are a bunch of poor nations plus USA, UAE, Qatar, Canada and Australia. I guess our medicare system supports the EU mothers fine enough so we don’t need to put that in the staple of food.

https://pmc.ncbi.nlm.nih.gov/articles/PMC5809909/ (Table 1)

WrongAssumption

Or you have just been sweeping preventable birth defects under the rug. The UK determined that had been happening and are going to start doing it.

https://www.bbc.com/news/articles/c206d60xe7no

mandevil

https://pmc.ncbi.nlm.nih.gov/articles/PMC8264257/

2023 Study:

"Despite Public Health Initiatives across Europe recommending that women take 0.4 mg folic acid before becoming pregnant and during the first trimester, the prevalence of NTD pregnancies has not materially decreased in the EU since 1998, in contrast to the dramatic fall observed in the USA. This study aimed to estimate the number of NTD pregnancies that would have been prevented if flour had been fortified with folic acid in Europe from 1998 as it had been in the USA."

"Conclusions: This study suggests that failure to implement mandatory folic acid fortification in the 28 European countries has caused, and continues to cause, neural tube defects to occur in almost 1,000 pregnancies every year."

The most famous NTD is Spina Bifida, and most of them aren't really fixable by modern health care. So this is 1000 babies a year who are either born with severe birth defects, or, in what I'm guessing is many cases, terminated when they could have been born healthy with a flour enrichment mandate.

hilbert42

It would be interesting to know why EU countries chose not to mandate it. Also, I wonder if EU flour millers/producers add it voluntarily, and whether flour produced in Canada destined for EU markets leaves out the folate that's mandated for inclusion in the Canadian market.

FollowingTheDao

I am against adding anything to a whole population to treat a few, folate included. Here is why. Folate is a known stimulant of some cancers.

https://aacrjournals.org/cebp/article/17/9/2220/169762/Folic...

https://link.springer.com/article/10.1007/s13668-018-0237-y

https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1463-1318....

(And you know that the first line cancer treatments, like methotrexate, are anti-folates.)

So while we are lowering birth defects, are we increasing cancers at the same time? Has this ever been studied?

We are not a homogeneous population.

The same is true for fluoride. Some people have a fluoride allergy:

https://www.aaaai.org/allergist-resources/ask-the-expert/ans...

And while fluoride is known to prevent cavities, it also makes tooth enamel brittle:

https://www.nature.com/articles/s43246-024-00709-8

https://www.medindia.net/news/healthwatch/fluoride-strengthe...

So I prefer to medicate myself, according to my own needs and my own genetics, thank you.

hansvm

Anti-folates (similarly with magnesium and a few other things) are closer to chemotherapy than anything else. They promote cancers because they promote nearly every human cell, and the logic behind removing them is that since cancer cells divide so comparatively rapidly they'll be selectively targeted by a lack of division-enabling nutrients. Most people absolutely shouldn't be restricting their folate intake.

If we take your claim to its logical conclusion (that we shouldn't add those vitamins and minerals to our foods because they might hurt a small percentage of people), the other side of the coin is that we should _remove_ extra vitamins and minerals. If we don't, we're just implicitly medicating a whole population rather than proactively medicating them. Peanuts hurt some people; let's ban them everywhere. End-stage kidney patients without full renal failure often can't tolerate salt or phosphorus; let's not salt any of our food and ban the sale of eggs and meats. Diabetics can't easily tolerate a high glycemic load; let's be extra safe and not use any sugars or alcohols.

Or...make reasonable population-level interventions and let people with special needs handle their own special needs. There are gluten-free breads, no-excess-folate flours, and all sorts of things on the market.

While we're talking about baseline levels of B vitamins (folate), did you know that most bakers are also dumping a rich, broad-spectrum source of most B vitamins and trace minerals into your bread? It's not just folate. They then let that yeast further multiply for 2hr+ just to bump the vitamin levels up (or, worse, add extra yeast at the start to speed up the baking cycle).

hilbert42

Presumably, if you're in the US or any of those countries that mandate folate then you don't eat bread or anything containing flour—or you have to get special flour without it.

I'd imagine that must be very difficult for you.

BTW, that fluoride reference refers to excessive fluoride in water whether natural or added. I've not entered the fluoride debate here except to ask a question. I'd certainly object if fluoride levels were excessive in my water supply.

nobodyandproud

So instead of the niche individuals and groups working around society to meet their needs—because this absolutely can be done today—-those with an anti-flouridation belief are mandating that the majority give up economy of scale for something that it still wants and needs.

It’s doubtful that this stance is being promoting in good faith.

karparov

It's also restricting the freedom of communities if you ban them from adding fluoride to their water if they like to.

This ban is anti-freedom. (Just like forcing them could be argued to be, even though that's what you argued against.)

So, this ban is arguably reducing freedoms on multiple levels.

kebman

Personal freedom ≠ "freedom of communities"—there is no such thing. Freedom applies to individuals, not collectives. When a community makes a decision that affects all its members, that’s democracy, but democracy is not unlimited authority. A majority vote does not grant the right to infringe on individual autonomy, which is why safeguards exist against the tyranny of the majority.

Banning fluoride does not restrict freedom—it prevents government overreach. In contrast, forcing fluoride on everyone would violate personal autonomy. Protecting individual choice is a fundamental principle, backed by real-world safeguards like constitutional rights, judicial review, and bodily autonomy laws. The burden of proof is always on those seeking to impose a policy, not on those defending individual freedom.

nulbyte

> Freedom applies to individuals, not collectives.

In the US, it most certainly does. We have freedom to associate, and associations also have freedoms. Were it not so, we wouldn't have even been able to arrive at the conclusion we have with regard to corporate money in politics.

alistairSH

But nobody is forced to drink municipal water. You can go to the grocery and pallets of gallon jugs if you prefer.

pclmulqdq

In the political philosophy of the US, the unit whose freedoms matter is the individual, not the community. Freedoms for individuals necessarily come from reducing the freedom of "the community."

maxerickson

Why are the remaining individuals in the community forced to include your individual in their decisions?

(I'm not being serious, I'm pointing out that you may not have found your first principle just yet)

swasheck

yes, and i think that’s a pretty recent reading of the US comprehension of freedom. my sense is that the collective individualistic tendencies have ballooned.

even as recently as the early 90s, my civics classes emphasized the importance of other people’s rights and that of the expression of your individual rights infringed on the rights of others then it was an irresponsible and improper use of individual rights.

it seems like this has devolved into people whose perspective on individual rights loosely aligns enough to coalesce and shout the loudest to create policy. until someone in the in-group’s individual freedom is impacted and the group fractures into smaller coalitions. rinse. lather. repeat.

regularjack

AKA as the spoiled brat kind of freedom.

Mordisquitos

But, taking the individual freedom argument to its ultimate implications, the Free individual is also Free to not drink tap water in a community that decided to add fluoride to their water supply, and is also Free to move to a community that decided against it.

You joke, but a lot of these freedom-rah-rah-rah people absolutely cried like babies and resisted seatbelt laws back in the 80s and 90s, too. Half my family believed it was evidence a communist takeover, and they all had those little defeat devices that you plugged into the latch, which silenced the car's seatbelt-off indicator.

"You can't tell me what to do" has been a religion in the USA for a long, long time.

nerdponx

How is fluoridating water better than giving out free toothpaste and toothbrushes? Has the latter been tried?

"Not keeping people trapped in poverty" would be nice too but for some reason that one seems off the table.

thordenmark

We've been trying for the history of mankind to figure out how to "not keep people trapped in poverty". No one has solved that problem yet, despite the best of intentions with monumental effort. I'll agree with Milton Friedman on this, Capitalism, as bad as it is, has been the most successful system to alleviate poverty.

nerdponx

This is getting wildly off topic, but I firmly believe that "we tried everything and free market capitalism is the best we have" is a myth.

It's incontrovertible that, under certain conditions, an unrestricted price system (a "market") is the most efficient allocation mechanism possible. There's a lot of research on that kind of thing.

The myth is that we have ever tried anything resembling that on a nationwide scale, or maybe even that it is achievable at all. There is a fundamental "paradox of tolerance" in economics, where market participants have strong and persistent incentives to distort or damage the market. This is why business interests so often align with free-market liberalism or conservatism.

Most of the so-called deregulation under the current Trump administration for example as little to do with improving the efficiency of market allocation. It's much more about making sure very large and powerful corporations can get even larger and more powerful, and removing the regulatory apparatus to prevent them from distorting and damaging markets to suppress competition, or to suppress labor costs.

Rather than taking choice away, we should be educating people on what the best choice is and letting them make it themselves.

Brush your teeth in the morning and in the evening. Standard dental hygiene - If a person can be an obedient worker they can probably brush their teeth twice a day. If they cant, they have bigger problems to sort out.

> educating people on what the best choice is and letting them make it themselves.

If we go that way, we should have some sort of Department, to make sure Of the Education being consistent.

rusk

This is a fair point, and in modern times, where we have good public health education it makes more sense to take this approach.

However this comes with the weighty caveat that there are public groups that actively agitate against public health campaigns.

On balance I think defluoridation makes sense where you have good public health communication.

NomDePlum

Is that not just a passive form of putting fluoride in the water though? Government is still spending money but without the desired outcome of having a healthier fitter population.
