播音员: 本期节目讨论了美国自来水中添加氟化物引发的争议。氟化物被认为是20世纪公共卫生领域的一大成就,有助于预防龋齿,尤其是在儿童中。然而,近年来,一些人开始质疑氟化物的安全性,担心其可能导致智力下降、甲状腺疾病甚至癌症等问题。美国新任卫生部长罗伯特·F·肯尼迪小儿公开反对在饮用水中添加氟化物,进一步加剧了这场争论。 本节目旨在探讨氟化物的科学依据,分析其潜在的益处和风险,并解答公众的疑问。 Phoebe Hobson: 美国民众对氟化物添加的争议由来已久。氟化物最初添加于约80年前,旨在预防龋齿。然而,近年来,人们越来越关注其潜在的健康风险,特别是罗伯特·F·肯尼迪小儿担任卫生部长后,反氟化物运动更加活跃,声称氟化物可能对儿童智商等造成负面影响。一些研究报告也为这一观点提供了支持,但这些研究中氟化物的含量远高于美国饮用水的标准。 此外,这场争论也涉及到个人选择权的问题,即人们是否有权选择是否摄入氟化物。反氟化物运动在社交媒体上非常活跃,但也有许多专家和机构支持在饮用水中添加氟化物,认为其益处大于风险。 Michelle Roberts: 氟化物是一种天然矿物质,适量摄入对牙齿健康有益,可以增强牙釉质,预防龋齿。然而,过量摄入氟化物可能导致牙齿氟斑症、骨骼和关节损伤等问题。一些研究也探讨了氟化物与神经毒性、儿童智商之间的潜在联系,但目前缺乏强有力的证据。世界卫生组织(WHO)已制定了饮用水中氟化物的安全限值,以确保公众健康。

Shownotes Transcript

Fluoride has been in most American tap water for decades. It’s there to help to prevent tooth decay, especially in children. Scientists and health officials say it’s one of the biggest public health wins of the 20th century.

But lately, fluoride has found itself at the centre of a heated debate, with some people concerned about side effects. Robert F Kennedy Jr, the US Health Secretary, is one of those, but he has long expressed views that conflict with scientific evidence.

We break down the facts about fluoride, explain how the quantities of it in water is safe and tell you what you need to know with Phoebe Hopson, a BBC reporter, and Michelle Roberts, a doctor and health reporter.
