水裡的氟化物是為什麼？｜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.
本週，猶他州成為美國第一個禁止在公共用水中使用氟化物的州。氟是一種天然礦物質，在土壤、植物和食物中含量極少。研究表明，在最佳水準下，它有助於防止蛀牙，有助於預防齲齒。自 20 世紀 40 年代起，美國就開始在公共飲用水系統中添加這種物質，以改善牙齒健康，這種做法被認為是上世紀最偉大的公共衛生成就之一。但這也造成了一些爭議，關於在公共飲水中添加氟化物的爭論愈演愈烈，佛羅里達州等一些州正在步猶他州的後塵，通過法律禁止添加氟化物。支持禁止在飲用水中添加氟化物的人指出，有研究表明，攝入高濃度的氟化物可能會對兒童的
- 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.
因為它有助於強化牙齒琺琅質，預防齲齒。事實上，美國疾病預防控制中心將其稱為上世紀十大公共衛生干預措施之一，因為它的效果非常好。牙醫們稱這是防治齲齒的前線防禦措施之一。他們非常喜歡這種方法，因為它可以幫助社區裡的每一個人，無論他們是否有能力支付去看牙醫或購買氟化物產品。是以，它確實為口腔健康建立了一種基線防禦。目前，美國約有三分之二的人口使用含氟公共飲用水。當然，這種情況正在開始改變。我們看到各州開始禁止在飲用水中添加氟，從猶他州開始，也許還有佛羅里達州，以及其他州。在美國，氟的濃度高於建議濃度時，可能會影
