The last defense of water fluoridation just died – along with a whole lot of fish – off the coast of India.

For decades, so-called health “authorities” bent over backwards to defend fluoride – even though most countries refuse to put fluoride in their water.

Studies showing fluoride lowered kids’ IQs?

They brushed them off.

Troubling links between fluoride and heart disease and Alzheimer’s?

Nothing to see here.

And they always used the same exact excuse

But that excuse just collapsed in a new study that nobody in America is talking about.

And once you see the results, you’ll never look at fluoride the same again.

U.S. Health Secretary Robert F. Kennedy, Jr. has been labeled a crackpot for calling fluoride “industrial waste” and questioning why it’s in our water.

But let’s see who the crackpots are now…

You see, every time a study emerges on the negative health effects of fluoride, its defenders are always ready with the same excuse – that the researchers used far higher levels of fluoride than you’ll find in American water.

But, like I said, that excuse just died a cold, hard death.

Sri Lanka is an island nation off the coast of India – it has about as many people as Florida. And in Sri Lanka, they have a problem – they’re seeing a rash of cases of “chronic kidney disease of unknown etiology.”

That basically means they don’t know what’s causing it – and they thought fluoride in the water may be to blame.

So they took samples from different wells and exposed zebrafish to the water. And that’s when the carnage happened.

First off, zebrafish embryos started dying off in droves.

And the ones that survived? They didn’t fare much better. They were suffering from serious developmental delays and birth defects.

The harmful effects were multiplied when fluoride was found in hard water – and most of America has hard water.

But here’s where things get even crazier…

The HIGHEST fluoride concentration the Sri Lankans found in any well was 1.24 ppm – that is less than ONE-THIRD of the 4 ppm that is allowed in American water.

This stuff was toxic at MUCH LOWER doses than what we get out of our taps every day.

So much for researchers using artificially high fluoride concentrations, right?

And this isn’t exactly the only recent, alarming study on fluoride.

A research summary published in January on fluoride and heart disease found that “fluoride exposure caused myocardial and cardiac functional damage.”

The more science that emerges on fluoride, the more bad news we seem to get.

Don’t expect your local health authorities – who have blindly defended fluoride for decades – to finally see the light of day. This is one situation you’re going to have to handle yourself.

If you want to remove fluoride from your water, try an activated alumina filter or a home reverse osmosis system.

And if your neighbors think you’re crazy, just tell them you’re doing what most of the world does – keeping fluoride out of your water.

To a tall glass of truth,
