水道水にフッ化物が含まれているのはなぜ？ | 2025年5月7日 (Why is Fluoride in our Water? | May 7, 2025)
- We begin today in Utah, which this week became the first U.S. state to ban the use of fluoride in public water. Fluoride is a natural occurring mineral that can be found in soil, plants, and food in tiny amounts. And studies show that at optimal levels, it helps prevent tooth decay, helps prevent cavities. The U.S. has added it to public drinking water systems since the 1940s to improve dental health, and the practice is considered to be one of the greatest public health achievements of the last century. But it's created some contratoms, with debate over adding fluoride to public water ramping up, and some states like Florida are following in Utah's footsteps to pass laws to ban it. Those in favor of banning fluoride in drinking water point to research that shows consumption of high levels of fluoride could cause adverse health effects in children, but exposure to levels that concentrated are rarely seen in the U.S. Proponents of the ban add that when it comes to fluoride improving dental health, evidence is mixed, and some studies find that our modern dental hygiene routines like brushing and flossing regularly have had more of an impact than fluoride in drinking water. Other advocates of the ban acknowledge that fluoride does have benefits, but people should have the individual choice to not have it added to their drinking water.
ユタ州は今週、公共水域でのフッ化物使用を禁止する米国初の州となった。フッ化物は天然に存在するミネラルで、土壌や植物、食品に微量に含まれている。そして、最適なレベルであれば、虫歯予防に役立つという研究結果もある。アメリカでは1940年代から、歯の健康を改善するためにフッ素を公共の飲料水に添加しており、この習慣は前世紀における公衆衛生の最大の成果のひとつと考えられている。しかし、フッ素の公共水域への添加をめぐる議論が活発化し、フロリダ州のようにフッ素を禁止する法律を制定しようとする州も出てきている。飲料水への
- United States because it helps strengthen our teeth enamel and helps prevent cavities. And in fact, the CDC has called this one of the top 10 public health interventions of the last century because it does this so well. Dentists have called this one of the frontline defenses, really, against cavities. And they like this approach so much because it can help everybody in a community regardless of their ability to pay to go to the dentist or buy fluoride products. So it really creates a baseline sort of defense for oral health. About two-thirds of the U.S. population currently has fluoridated public drinking water. But of course, that is starting to change. We are seeing states start to ban adding fluoride to drinking water, starting with Utah, perhaps Florida, and others as well. And the concerns there really have been around fluoride's potential to affect brain development at higher levels than is recommended in the U.S.
歯のエナメル質を強化し、虫歯予防に役立つからだ。実際、CDCはこれを前世紀の公衆衛生介入策のトップ10のひとつと呼んでいる。歯科医は、これを虫歯予防の最前線と呼んでいる。歯医者に行くお金やフッ化物製品を買うお金を払う能力があるかどうかにかかわらず、地域社会のすべての人を助けることができるからだ。つまり、口腔の健康を守るための基本的な防御策となるのだ。現在、米国の人口の約3分の2がフッ素入りの公共飲料水を利用している。しかし、もちろんそれは変わり始めている。ユタ州を皮切りに、おそらくフロリダ州やその他の州で
