外媒稱,全英98%的診所進(jìn)行的一項(xiàng)調(diào)查發(fā)現(xiàn),英國飲用水氟化物含量最高地區(qū)的居民中,甲狀腺功能減退(簡稱甲減)發(fā)病率高出其他地區(qū)30%。
據(jù)英國《每日電訊報(bào)》網(wǎng)站2月23日?qǐng)?bào)道,近日,科學(xué)家稱,氟化物或可引發(fā)抑郁情緒并令體重增加,并警告英國相關(guān)部門應(yīng)停止為防蛀牙在飲用水中添加氟化物的做法。
英格蘭公共衛(wèi)生局去年公布的一份報(bào)告稱,在飲用水中添加氟化物是改善口腔健康的一種“安全有效”的方式。
然而,肯特大學(xué)的最新研究顯示,在西米德蘭茲和英國東北部等飲用水含氟量較高的地區(qū),甲減的發(fā)病率大幅攀升。
研究報(bào)告主筆、肯特大學(xué)保健問題研究中心的斯蒂芬·佩卡姆教授說:“甲減是一個(gè)令人相當(dāng)不快的疾病,它會(huì)引發(fā)其他長期健康問題。我真的覺得相關(guān)部門應(yīng)重新考慮是否要在飲用水中添加氟化物。其他可改善口腔健康的方法比這要安全得多。”
英國大約有10%的人口居住在飲用水天然含氟或人工添加氟化物的地區(qū),氟化物含量達(dá)每升1毫克。
氟化物能夠增進(jìn)牙齒琺瑯質(zhì)的抗菌能力,以防蛀牙產(chǎn)生。此前有研究指出,氟化物會(huì)抑制碘的生成,而碘是人體維持甲狀腺健康必不可少的關(guān)鍵要素。
甲狀腺負(fù)責(zé)調(diào)節(jié)身體的代謝和其他諸多機(jī)體功能。甲減會(huì)引發(fā)抑郁情緒,導(dǎo)致體重增加,令人產(chǎn)生疲乏感和肌肉疼痛。
Foreign media, according to a survey of the UK 98% of clinic found that British residents drinking water fluoride content in an area with the highest, the incidence of hypothyroidism (hereinafter referred to as JiaJian) 30% higher than in other regions.
According to the British "daily telegraph" website reported on February 23, recently, the scientists say that fluoride may trigger depression and increase in weight, and warned that Britain's related departments should stop to moth-proofing teeth add fluoride in drinking water.
Adding fluoride to drinking water is a "safe and effective" way to improve oral health, according to a report published last year by England's public health service.
However, new research from the university of Kent shows that in areas with high levels of fluoride in drinking water, such as west midlands and the North-East of the UK, the incidence of hypothyroidism has soared.
Lead author professor Stephen pecam, of the university of Kent's centre for health research, said: "hypothyroidism is a fairly unpleasant disease that can cause other long-term health problems. I really think the authorities should reconsider adding fluoride to drinking water. Other ways to improve oral health are much safer.
About 10 per cent of the population lives in areas where drinking water is naturally or artificially fluoridated, with up to one milligram of fluoride per litre.
Fluoride improves the antibacterial ability of tooth enamel to prevent cavities. Previous studies have shown that fluoride inhibits the production of iodine, a key ingredient in keeping the thyroid healthy.
The thyroid regulates the body's metabolism and many other bodily functions. Hypothyroidism can trigger depression, leading to weight gain, fatigue and muscle pain.
