flouride

Yeah, by this argument lead in the water isn't a concern.

It's so funny I was just having a similar conversation about neurotoxic venomous animals in another thread. Lethality is an obviously concerning threshold, but there are substances out there that can easily destroy your quality of life and livelihood that never reach the concern of being lethal.

I think for mostly rational people concerned about fluoride in their water is that it was a public health decision made with little to no actual science proving it's safety or efficacy when it was first decided that they were going to add it to the public water supply. The proposed benefits of it weren't even supported by scientific evidence, it was just supposed that exposure to sodium fluoride could potentially reduce tooth decay for some.

Personally, I've suffered from the cosmetic damage of dental fluorosis, and I'm not necessarily thrilled about fluoride. But I have way more issues with public mandates founded on pseudoscience than I am with sodium fluoride. Especially now that we can see evidence that for some people fluoride can be especially beneficial.

So what was wrong with giving people the option of using fluoride toothpaste or mouthwashes... Why did it have to go into the public water supply?

never the concern

It is when you're responding to people who think 5G is turning the frogs gay and activating hidden vaccine microchips.

We probably have enough A/B data now to make some inferences yeah? Compare countries with fluoridated water to countries without.

Yeah, it seems to me like he got the right idea and wanted to convince people by making an extreme statement..

This. How can we be completely certain that something isn't damaging over the long term. I'm not anti fluoride, but healthy debate and scepticism is a good thing, especially when we're all forced to consume a substance with the only alternative being dehydration and death. People need to be free to make their own choices.

Also, isn't it recommended to not give infants fluorided water, hence why you can buy it in virtually every grocery store?

Fluoride does have long term effects though once you consider fluoride exposure through all sources like diet, which is mostly due to fluoride from water ending up in farmland. Tradesmen alone regularly exceed the upper limits due to high water consumption in hotter seasons

Also "because I'm an expert and I say so" is a good way to convince someone to let you poison them.

And both of these people telling me about fluoride in water are both experts in their field. One an expert toxicologist, and the other an expert liar. Now I don't know what to believe.

Its presence in groundwater is how we discovered it's good for teeth.

In fact, there used to be so much in some areas,it actually stained the teeth. In Colorado Springs a dentist noticed that the children were developing brown stains on their teeth. In researching it, it was discovered that the "Colorado Brown Stain" was caused by excessive fluoride in the drinking water. But it also lead to the discovery that regions with natural fluoride present but in lower levels than Colorado Springs didn't have stained teeth, but did have lower levels of tooth decay.

Small note: the country name is spelled “Colombia,” and spelling it correctly means you don’t need to specify which one!

Just because a concentration is low doesn’t mean it’s safe. Water with 0.7 mg/L of Po-210 is lethal.

You can put an amount of it in a 55 gallon drum that is not visible

It’s a natural substance

Fluoride is in fact safe at the amounts that the FDA regulates but saying it’s a small concentration or that it’s natural are not the reasons it’s safe. It’s the hundreds of peer reviewed research articles that show that it’s safe

Like the ol' General said / s

We can no longer sit back and allow Communist infiltration, Communist indoctrination, Communist subversion and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.

Fluoridation is the most monstrously conceived and dangerous communist plot we have ever had to face.

I mean, trump got reelected. I hope it's the flouride.

And that's why you should only drink grain alcohol and pure, natural rain water. To preserve the essence of your precious bodily fluids.

Fun fact. Literally everyone who has died, ever, has had DHMO in some form. You're even exposed in the womb!

Why is some dumb scientist expert trying to tell me, a person who pays for an internet connection, what the truth is?

Thats what the fluoridiots say.

Drink your water, or get the FOOF.

I didn’t know this was a thing when I was younger, but not young enough to not be classified as a moron.

Drank about 7-8 litres of water in 3 hours without going to the bathroom as a contest against a work colleague. Suffice to say I started feeling a little off on the way home, even after going to the bathroom. Years later I finally learned you can drown yourself from drinking too much and the symptoms were eerily close to what I experienced that night.

There’s a follow up meta study from 2020.:

In conclusion, based on the totality of currently available scientific evidence, the present review does not support the presumption that fluoride should be assessed as a human developmental neurotoxicant at the current exposure levels in Europe.

A study in Canada was published in 2019 looking at the differences between 2 neighboring cities where on stopped fluoridating water in 2011. They saw that saw a significant increase in cavities in children in the city that stopped fluoridating vs the other. This is despite the fact the the city without fluoridation actually has somewhat higher adherence to brushing, flossing, and going to the dentist. No difference was seen yet in permanent teeth, but that's because the study would need more time to see effects there.

https://onlinelibrary.wiley.com/doi/full/10.1111/cdoe.12685

Of course, we still should do more studies on fluoride neurotoxicity. Most studies look at levels of fluoride at 1.5mg/L or higher, which is more than double the recommended level by the US (0.7 mg/L). There is a hard limit in the US of 4mg/L, but the EPA strongly recommends a limit of 2mg/L. This only really matters for locations with very high levels of fluoride in the groundwater, and is thus quite rare. The EU's limit is 1.5mg/L.

I also came across the same study while looking to disprove a conspiracy nut. We should really do more research on the effects of fluoride.

The Takeaway I’m getting from both of these studies being talked about Is that things are very unclear. The Cochrane group is very well regarded for conducting Meta studies and finding flaws in previously held understandings. The term high fluoridation is mentioned many times, and it’s unclear what that is meaning.

Vitamin A is an incredibly important molecule to many biological processes in the human body, but we do not want to supplement it, aggressively, as it can become toxic. Fluoride is noted to be beneficial for enamel hardening. No one is recommending taking large amounts of it. The second link you have points out the important questions, what is the actual danger, and who is in danger the most?

You want some fancy rebuttal to a single linked study that the article states was a bunch of partials thrown together, that came from a country famously known for half-assing and cutting corners to get ahead? The country that was caught mixing lead into ground Cinnamon to sell it for a higher weight? The one where buildings sit half done or the cement falls apart by the time it's together? The ones who lay sod over cement in order to pass the amount of vegetation present on new construction?

That's the article you could and and latch onto in order to believe? Are you even aware that fluoride occurs naturally in water and that about 40% of all the drinking water across the globe already has around the amount the US gets theirs up to, or a larger amount(some places so large they do actually cause health issues)? It's literally been drank for thousands of years.

But you trust an incomplete study from China more than anything else? Why?

It does do this. However so does ageing, low sunlight exposure, low altitude, ethnicity, sex, nutrition, neuro-divergence, cell phone use, EM fields... you get the idea.

Another point that conspiracy bros will bring up is that fluoride is a toxic byproduct of aluminum manufacture and dumping it into the water supply is a cheap way for Alcoa to dispose of it benevolently.

I can no longer sit back and allow Communist infiltration, Communist indoctrination, Communist subversion, and the international Communist conspiracy to sap and impurify all of our precious bodily fluids.

Second time I got to post this today, unfortunately because it's almost ceased being satire.

I don't understand your point.

Nobody drinks the ocean. Fluoride is barely active topically. Most humans rarely if at all swim in the ocean.

This is a better argument than the one in the post. No one is worried about acute toxicity of fluoride but rather long term. But it's not long term toxic, doesn't accumulate in the body, and is only present in very low amounts in water. However it should be enough to use fluoridated toothpaste to get the positive effects.

Why not just get a water filter?

Thank you for the link. It's worth mentioning that there are response letters to the publication you linked from other experts, the majority of which are critical and point out misinterpretations and omissions by the author. It's always good to question, but in this instance it looks like the consensus amongst experts evaluating that publication is still that fluoridation is safe and improves dental health. The response letters can be read here.

Edit to add: The responses include a letter from the dean of the Harvard School of Dental Medicine stating that the publication is deeply flawed and requesting a retraction, and a similar condemnation from the students of the Harvard School of Dental Medicine. The article was given greater weight by being linked to Harvard, but in fact Harvard dental experts explicitly disagree.

This is a disingenuous take. This is a cherry-picked article that does not come to the conclusion you draw here. You also state "It does have neurological effects" but leave out the most important piece of information for that to be true: high doses.

Why should anyone trust what you say when you're twisting the information to suit your narrative?

Counterpoint: I live in an area without fluoridated water, and I'm told that dentists can reliably identify people who didn't grow up here by the state of their teeth.

I appreciate that you put some reputable sources, rather than relying on a random tweet/post.

Your link is more or less an opinion piece from a geneticist, so this isn't even her field of study.

All her health issues she points out are for fluoride concentrations over triple the amount that tap water is brought up to.

The reason it's usage spread across the country was because while the entire country had access to things such as fluoridated toothpaste, counties and cities that started fluoridation of their water supplies consistently had fewer cavities than areas that didn't fluoridate the water. This alone outlines the glaringly obvious flaw in her argument.

Further still, while the US adds fluoride to the tap water in a concentration to reach 0.5mg to 0.7mg per liter of water (a couple drops per 50 gallons), natural drinking water for over 20% of the world is in concentrations well over that (to be clear, being well over that can cause health issues. Too much of anything can cause health issues.)

In other words, there is no evidence that this low concentration of fluoride causes health issues. There is loads of direct evidence that it reduces cavities. Plus, this woman from your opinion piece is talking out of her field. Not to mention that 21% of the world's drinking water supply naturally already falls within the recommended range of what the US takes theirs up to. It's just that most of the US water supply naturally falls below that amount.

Only 3% of Quebec's population has access to fluoridated water and we have way more dental issues than any other province in Canada.

Interesting. The article doesn’t actually say that fluoridation in water supplies is dangerous but that some researchers are questioning. Generally code for lack of scientific evidence. It also finds that early studies may have had a flawed basis (pretty much all early studies have been found wanting by later scientists) but doesn’t refute the results.The study mentioned in the article talks about high levels of fluoridation which I assume is in lab tests however these levels are not the case in water supplies.

The correct way forward is more actual science based studies.

The bad part about Rfk jr is he probably mixes in some science with quackery. I honestly assumed all his ideas are insane. That's what's so hard about being discerning right now, you have to be on one side or the other.

Most places that do add it to the water supply match the levels of places where flouride occurs naturally

Welcome to Science Memes, where the science isn't memes and the memes aren't about science.

Without Fluoride all the humour in the world dies.

The meme is now this is not US policy.

Its like stating the world is not flat... when in fact NASA's official stance is that the world is, indeed, flat.

0.08mg per half cup serving, but may vary depending on water used. https://ods.od.nih.gov/factsheets/Fluoride-HealthProfessional/

10mg is the accepted daily upper limit for an adult. So 62.5 cups of oatmeal to reach that max safe limit. https://ods.od.nih.gov/factsheets/Fluoride-Consumer/

Acute poisoning symptoms may appear as low as 10-15 mg/kg, lethal dose might be 32-64 mg/kg. https://en.wikipedia.org/wiki/Fluoride_toxicity

So 200 to 400 cups of oatmeal per kg you weigh for a lethal dose. (32/0.08/2=200, 64/0.08/2=400)

many toothpastes have it, no need to use multivitamins

Well look at the statistics:

Fluoride:

• Water fluoridation in the United States began in the 1940s
• By 1949, nearly 1 million Americans were receiving fluoridated tap water
• In 1951, the number jumped dramatically to 4.85 million people
• By 1952, the number nearly tripled again to 13.3 million Americans
• In 1954, the number exceeded 20 million people
• In 1965 an additional 13.5 million Americans gained access to fluoridated water.
• By 1969, 43.7% of Americans had access to fluoridated tap water.
• In 2000, approximately 162 million Americans (65.8% of the population served by public water systems) received optimally fluoridated water
• 2006: 69.2% of people on public water systems (61.5% of total population)
• 2012: 74.6% of people on public water systems (67.1% of total population)

Autism:

• First recognised in the 1940s
• During the 1960s and 1970s, prevalence estimates were approximately 0.5 cases per 1,000 children.
• Prevalence rates increased to about 1 case per 1,000 children in the 1980s.
• 2000: 1 in 150 children
• 2006: 1 in 110 children
• 2014: 1 in 59 children
• 2016: 1 in 54 children
• 2020: 1 in 36 children

Seems pretty clear cut to me.

/s because people think I posted this in seriousness.

Sadly, flouridation conspiracy theories predate RFK Jr. by a long, long time.
