自从Dean等证实饮用浓度为1 ppm的氟水能降低龋齿的患病率以来,调节氟水浓度达1 ppm就成为美国最重要的公共卫生计划,并被其它许多国家广泛接受,尤其是世界卫生组织。但在经过一段时间使用之后,从流行病学角度观察,氟化水源有慢性的副作用,面临着心理、政治和道德上的阻碍。为了解决在氟化水源时使用化学性氧化物的危害,作者认为应该考虑茶叶中可饮用的氟化物。日本几个世纪以来产茶,消费茶,相信茶有益无害。并且各种报告得知:茶干品中可
Since Dean et al. Have confirmed that drinking fluoride at a concentration of 1 ppm can reduce the prevalence of dental caries, regulating fluoride concentrations up to 1 ppm became the most important public health program in the United States and was widely accepted by many other countries, notably the World Health Organization organization. However, after some time of use, from the perspective of epidemiology, fluorinated water sources have chronic side effects and face psychological, political and moral obstacles. In order to address the dangers of using chemical oxides in fluoridated water, the authors believe that drinking fluoride should be considered in tea. Japan has been producing tea and consuming tea for centuries, and I believe it is beneficial and harmless. And various reports that: tea dry goods can be
