a “dangerous neurotoxin” tied to a range of health dangers. Last month, he announced a task force to scrutinize fluoride’s use, while at the same time saying he would order the CDC to stop recommending that it be added to tap water.A report last year by the federal government’s National Toxicology Program concluded that drinking water with more than twice the CDC’s recommended level was associated with lower IQs in kids. The study was based on research conducted in Canada, China, India, Iran, Pakistan and Mexico.

“Ending the use of ingestible fluoride is long overdue,” Kennedy said in a statement Tuesday. “This decision brings us one step closer to delivering on President Trump’s promise to Make America Healthy Again.”An influential government health panel recommends fluoride supplements for children between the ages of six months and 5 years if they live in areas with low fluoridation levels. The U.S. Preventative Services Task Forces judged the recommendation to have “high certainty,” based on the available evidence.A 2010 paper from the ADA recommended supplemental fluoride for children up to 16 years old who are at high risk of cavities. The recommendation was based on a review of studies across different age groups. The most common side effect associated with the products is spotting or discoloration of the teeth, caused by extra fluoride.

ADA’s Kessler said the FDA’s plan “will be particularly harmful to the most vulnerable and those who lack access to care.”The FDA regulates most dental products, including fluoride-containing toothpastes, supplements, mouthwashes and rinses. But in Tuesday’s press release, the FDA said the ingestible products targeted by the agency have “never been approved.” The agency’s plan wouldn’t affect toothpastes, mouthwash or fluoride treatments used by adults or those offered in dentists’ offices.

In recent weeks fluoride-containing products have increasingly been targeted with lawsuits and legal actions.

Texas Attorney General Ken Paxton announced an investigation early this month into the marketing of fluoride toothpastes by Colgate-Palmolive and Proctor and Gamble. A press release from his office described the companies’ promotions as “misleading, deceptive and dangerous.”CUAUHTEMOC, Mexico (AP) — In a rickety white Nissan, nurse Sandra Aguirre and her

drive past apple orchards and cornfields stretching to the desert horizon. Aguirre goes door to door with a cooler. In one of Latin America’s biggest Mennonite communities, she knows many will decline to be vaccinated or even open their doors. But some will ask questions, and a handful might even agree to get shots on the spot.

“We’re out here every single day,” said Aguirre, pausing to call out to an empty farm, checking for residents. “To gain trust of the Mennonites – because they’re reserved and closed-off people – you have to meet them where they’re at, show a friendly face.”Aguirre’s work is part of an effort by health authorities across the country to contain
