Fairly bad faith argument on your part.

The limits are set such that if you _only_ drank tap water you won't consume more than the safe limit. If you then reduce how much tap water you consume because you get hydration from other sources, your well under the limit.

Not accounting for someone eating tubes of fluorinated toothpaste, which is out of specified usage.

OK, that makes sense. What is the recommended dosage of fluoride?

[btreecat]

The current upper limit consider safe to consume with regularity, is "4 milligrams of fluoride per liter of water"

The CDC sets the recommend fluorination levels are 0.7 mg/L, more than 4x lower than the amount considered safe to consume.

So you would need to consume over 20L of water (think 10 2L soda bottle worth).

I couldn't personally physically do that.

Absolute nonsense.

The coffee, soda, beer, or kombucha you drink was made with fluoridated water. Your salad was grown with fluoridated fruit was washed in fluoridated water.

Fluoride permeates modern supply chains because it’s literally in the water which is an input to countless things.

Fluoride proponents have utterly failed to control dosage and harmed public health in doing so.

How much flouride? And from what sources?

Typically farms need wells because of how much water infrastructure they need can't generally be supported by municipal water. There are exceptions particularly in dense areas with vertical farms or urban farms but this doesn't align with your claim, that effectively everything we consume has some detectable level of flouride.

I bet you've already read this though

https://ods.od.nih.gov/factsheets/Fluoride-HealthProfessiona....

The only thing studied that contained more flouride than municipal water but still 3x less than the safe limit, is tea. And that was measured with distilled water to eliminate the water source as a variable.

Most tea isn't grown in the USA.

So your claims fall flat on their face here, but I'm not done.

How much? Making such a claim is fine if we want hand waved values. But when you want to be an Internet advocate for a specific policy, show up with receipts or don't show up at all.

See previous link for current source of information on food supply.

> Fluoride proponents have utterly failed to control dosage and harmed public health in doing so.

Based on what evidence?

You have utterly failed to show you have a solid grasp on the scientific method, public policy, and critical thinking.

1. Most tea consumed worldwide is of Asian origin. Camellia sinensis is native to East Asia.

"On any given day, more than one half of the American population drinks tea. On a regional basis, the South and Northeast have the greatest concentration of tea drinkers."

Tea may easily contain 5 to 10 times as much fluoride as fluoridated water.

2. TOTAL intake is what determines fluoride toxicity. This has been established since the 1930s when fluoride was discovered to be the source of "mottled enamel" - dental fluorosis.

In 1991, total intake among adults in fluoridated areas in the US was estimated to be up to 6.6 mg/day. (US PHS, 1991)

"The daily intake of most adults is about equally divided among food, drinking water, beverages, and mouthrinses." (U.S. Dept. Health & Human Services, Report on fluoride benefits and risks. MMWR Recomm Rep. 1991 Jun 14;40(RR-7):1-8. PMID: 2051975.)
