U.S. government report says fluoride at twice the recommended limit is linked to lower IQ in kids
NEW YORK (AP) — A U.S. government report expected to stir debate concluded that fluoride in drinking water at twice the recommended limit is linked with lower IQ in children.
The report, based on an analysis of previously published research, marks the first time a federal agency has determined — “with moderate confidence” — that there is a link between higher levels of fluoride exposure and lower IQ in kids. While the report was not designed to evaluate the health effects of fluoride in drinking water alone, it is a striking acknowledgment of a potential neurological risk from high levels of fluoride.
Fluoride strengthens teeth and reduces cavities by replacing minerals lost during normal wear and tear, according to the U.S. Centers for Disease Control and Prevention. The addition of low levels of fluoride to drinking water has long been considered one of the greatest public health achievements of the last century.
“I think this (report) is crucial in our understanding” of this risk, said Ashley Malin, a University of Florida researcher who has studied the affect of higher fluoride levels in pregnant women on their children. She called it the most rigorously conducted report of its kind.
The long-awaited report released Wednesday comes from the National Toxicology Program, part of the Department of Health and Human Services. It summarizes a review of studies, conducted in Canada, China, India, Iran, Pakistan, and Mexico, that concludes that drinking water containing more than 1.5 milligrams of fluoride per liter is consistently associated with lower IQs in kids.
The report did not try to quantify exactly how many IQ points might be lost at different levels of fluoride exposure. But some of the studies reviewed in the report suggested IQ was 2 to 5 points lower in children who’d had higher exposures.
Since 2015, federal health officials have recommended a fluoridation level of 0.7 milligrams per liter of water, and for five decades before the recommended upper range was 1.2. The World Health Organization has set a safe limit for fluoride in drinking water of 1.5.
The report said that about 0.6% of the U.S. population — about 1.9 million people — are on water systems with naturally occurring fluoride levels of 1.5 milligrams or higher.
“The findings from this report raise the questions about how these people can be protected and what makes the most sense,” Malin said.
The 324-page report did not reach a conclusion about the risks of lower levels of fluoride, saying more study is needed. It also did not answer what high levels of fluoride might do to adults.
The American Dental Association, which champions water fluoridation, had been critical of earlier versions of the new analysis and Malin’s research. Asked for comment, a spokeswoman late Wednesday afternoon emailed that the organization’s experts were still reviewing the report.
Fluoride is a mineral that exists naturally in water and soil. About 80 years ago, scientists discovered that people whose supplies naturally had more fluoride also had fewer cavities, triggering a push to get more Americans to use fluoride for better dental health.
In 1945, Grand Rapids, Michigan became the first U.S. city to start adding fluoride to tap water. In 1950, federal officials endorsed water fluoridation to prevent tooth decay, and continued to promote it even after fluoride toothpaste brands hit the market several years later. Though fluoride can come from a number of sources, drinking water is the main source for Americans, researchers say.
Officials lowered their recommendation for drinking water fluoride levels in 2015 to address a tooth condition called fluorosis, that can cause splotches on teeth and was becoming more common in U.S. kids.
Separately, the Environmental Protection Agency has maintained a longstanding requirement that water systems cannot have more than 4 milligrams of fluoride per liter. That standard is designed to prevent skeletal fluorosis, a potentially crippling disorder which causes weaker bones, stiffness and pain.
But more and more studies have increasingly pointed to a different problem, suggesting a link between higher levels of fluoride and brain development. Researchers wondered about the impact on developing fetuses and very young children who might ingest water with baby formula. Studies in animals showed fluoride could impact neurochemistry cell function in brain regions responsible for learning, memory, executive function and behavior.
In 2006, the National Research Council, a private nonprofit organization in Washington, D.C., said limited evidence from China pointed to neurological effects in people exposed to high levels of fluoride. It called for more research into the effect of fluoride on intelligence.
After more research continued to raise questions, the National Toxicology Program in 2016 started working on a review of the available studies that could provide guidance on whether new fluoride-limiting measures were needed.
There were earlier drafts but the final document has repeatedly been held up. At one point, a committee of experts said available research did not support an earlier draft’s conclusions.
“Since fluoride is such an important topic to the public and to public health officials, it was imperative that we made every effort to get the science right,” said Rick Woychik, director of the National Toxicology Program, in a statement.
Malin said it makes sense for pregnant women to lower their fluoride intake, not only from water but also from certain types of tea. It might also make sense to have policy discussions about whether to require fluoride-content on beverage labels, she said.

WASHINGTON (AP) — Mark Schiefelbein has been based in Washington, D.C., with AP for about three years, and before that spent a decade in Beijing at AP’s China bureau.
Here’s what he had to say about this extraordinary photo.
Why this photo?
This was an event that had never happened before in the 250-year history of the United States and may never happen again: a night of mixed martial-arts cage match brawls on the South Lawn of the White House, with bloodied competitors battling it out in front of the president, vice president, and other leaders of the country. AP had other photographers ringside at the event focusing more on the fights themselves. So I felt my role was to capture the context of the evening — the location, the people in attendance, the environment.
How I made this photo
A small group of other photographers and I, the White House press pool, had been allowed to photograph part of the evening from a position in the stands directly opposite the White House. I was carrying four cameras with a variety of lenses from 12 mm to 300 mm. This let me capture everything from ultra-wide views of the “claw” structure built for the fights, to close-ups of leaders and celebrities in attendance. I had been following Diego Lopes with my longest lens as he moved around the ring celebrating his win over Steve Garcia. When I saw him start to climb onto the cage, I immediately realized there might be a possibility of a picture like this and zoomed out to capture more of the scene.

Why this photo works
The White House is surely one of the most recognizable buildings in the world. The columns of the South Portico, the fighter standing with arms and legs spread wide in celebration, and the octagon padding of the UFC ring tell an entire story as your eyes move from top to bottom of the frame. With Lopes standing with his back to the camera, facing the White House, it becomes less a photo of him and more about the evening, the event, and the spectacle. It was fortunate that it was after nightfall, so things that might have been distracting, like the Marine Band and spectators seated behind the ring, are mostly in the dark. Only the key elements – the White House, Lopes, and the ring are lit up.

British Prime Minister Keir Starmer faces potential leadership challenge from newly-elected Andy Burnham
NEWYou can now listen to Fox News articles!
Andy Burnham has officially won his special election and regained a seat in Parliament, setting him up to challenge the deeply unpopular Keir Starmer as the leader of the Labour party and as prime minister.
Burnham, currently the mayor of Greater Manchester in northwest England, won a seat in Makerfield and came away with 55% of the vote in a field of more than a dozen candidates, according to The Associated Press. The runner-up was Rob Kenyon of Reform UK, a right-wing populist party, who received more than 9,000 fewer votes than Burnham.
Burnham last served as a member of Parliament in 2017 but strongly implied in his victory speech that he is returning with the intention to lead the United Kingdom.
“Everyone knows that politics isn’t working. Everyone can feel that the country isn’t where it should be. Tonight could, just could, be the turning point,” he said, according to the AP. “This result will bring about a country that works fairly for everywhere and for everybody.”
TRUMP ALLY NIGEL FARAGE DEALS MAJOR BLOW TO STARMER IN LOCAL UK ELECTIONS AS RESIGNATION CALLS MOUNT

This special election, called by-elections in Britain, was unusually significant because the area’s Labour MP, Josh Simons, intentionally resigned to allow Burnham to win the seat and pursue leadership.
The potentially outsized impact of this election was juxtaposed with the strange scene that unfolded when all the candidates gathered on Friday morning to hear the results. Burnham stood in between an independent candidate dressed in a fox costume and another candidate known as “Count Binface”.
As his name suggests, “Count Binface,” whose real name is Jonathan David Harvey, was wearing a trash can on his head and regularly runs in U.K. elections to advocate for increased voter turnout.
Starmer congratulated Burnham in a social media post on X, saying voters “chose Labour’s campaign of hope and optimism over division and hate.”
When asked about Burnham’s intentions to oust him as leader, Starmer said he will fight to remain prime minister, a position he has held for nearly two years.
“I’ve said repeatedly I’m not going to walk away from that,” Starmer told reporters.

AS EPSTEIN-LINKED APPOINTMENT SPARKS BACKLASH, UK PM STARMER FACES PARTY REVOLT AMID RESIGNATION CALLS
Starmer led the Labour party to a landslide victory in July 2024 and ever since, his popularity has been eroding thanks to a persistently high cost of living, an anemic economy and a scandal over his willingness to accept gifts from wealthy donors.
Last September, Starmer was slammed for appointing Peter Mandelson as the British ambassador to the United States, when it was known as early as 2019 that Mandelson had a friendship with convicted child sex offender Jeffrey Epstein. Following an enormous public backlash, Mandelson was quickly dismissed from his post.
With Starmer as leader, Labour is increasingly losing liberal-minded voters to the Green Party, while also facing stronger challenges by Reform UK, a Nigel Farage-led party that advocates against mass migration and in favor of tighter border controls. Farage, an ally of U.S. President Donald Trump, said he was disappointed by Burnham’s victory.
Burnham is expected to head to London to be sworn in as soon as Monday. Under the British parliamentary system, the governing party can hold leadership elections in the middle of the term. The winner of such a contest can become prime minister without there having to be a national election.

Under Labour rules, a lawmaker can challenge the leader if they win the backing of a fifth of their party’s members in the House of Commons. Burnham has enough lawmakers on board to trigger a leadership contest, according to a report from The New Statesman.
According to the AP, Culture Secretary Lisa Nandy said Burnham and Starmer will “have a conversation about what comes next” in the next few days.

French President Emmanuel Macron and Spanish Prime Minister Pedro Sánchez have issued a blistering rebuke against deportation camps outside the European Union, setting their countries on a collision course with a growing political majority.

During a summit on Friday, 19 leaders across the bloc signed a joint declaration calling to make “full use” of a new European law that enables the construction of so-called return hubs to host migrants whose asylum applications have been denied.
The coalition, led by Denmark and Italy, two fierce advocates of outsourcing, wants to “move forward with solutions based in third countries as soon as possible”.
But for Macron and Sánchez, this path runs counter to European values and risks squandering financial resources and undercutting relations with neighbouring Africa.
“I am not sure that this is our Europe. I don’t know if these are the fundamental principles on which our Europe was built,” Macron said at the end of the summit on Friday.
“And I don’t think it’s effective, either. The proof is that I have not seen anyone make it work so far,” he went on, underscoring his strong dissatisfaction. (Italy has set up migration centres on Albanian soil but has fallen short of expected targets.)
“I have a lot of respect for anyone who wants to do it. I disagree, both pragmatically and in principle. I think it has nothing to do with European politics.”
Macron said his country was in favour of tougher laws to curb irregular arrivals but drew a red line on the physical transfer of migrants to faraway countries where they have never set foot. That possibility, long considered taboo, is allowed under a revamped Return Regulation described as the “strictest-ever” migration law.
“There is a question, in fact, around these famous return hubs in third countries. France does not support this policy. We are in favour of a more effective return policy. But first of all, I have never seen a return hub in a third country operate,” Macron went on.
“I invite you to consider what it is (in practice): this means that people who do not want to return to their country of origin or who cannot get back to their country of origin will be pushed into a third country, which will accept them in return for money.”
Macron mocked the jargonistic term “innovative solutions” that proponents of migration offshoring often use in their public communication and challenged the notion that host countries would respect human rights in exchange for financial incentives.
“I am a big supporter of innovation in my country,” he said, saying he would later attend the Vivatech festival in Paris. “But I am always very careful when talking about innovation in values and human rights. Allow me to have that reservation.”
Meanwhile, Sánchez, a vocal critic of the measures, said the deportation camps would be an “absolutely inefficient” and “worthless” response to irregular migration.
“It’s a mirage, if you will, that it will simply waste economic resources, and Europe doesn’t have many,” the Spaniard said after the summit in Brussels.
“Secondly, it sends a wrong message to those countries of origin and transit with which we should be collaborating, cooperating and showing empathy towards.”
Macron echoed Sánchez’s reputational concerns and insisted he would not allow EU funds to be used in any capacity to build the deportation camps, which are “neither effective nor do they correspond with our principles”.
“Sometimes, we hear one or the other (country) advocate policies with the African continent, so good luck defending our credibility on these continents by explaining that we will use the money for investments to build return hubs on their continents,” he said.
