Israel is one nation that has it together, and when it makes some radical change, it would be wise to analyse it. Take fluoride in the water for example:

“Israeli tap water will no longer contain fluoride after Tuesday, following a decree by Health Minister Yael German earlier this month discontinuing the practice. The decision has been lauded by various rights groups, but criticized by many in the medical and dental communities as a serious mistake. Fluoride is commonly added to national water supplies by governments throughout the world in order to prevent tooth decay, but critics say overconsumption of the invisible, odorless, tasteless gas is a health hazard. Despite the widespread fluoridation, German, a member of the Yesh Atid party, has made no secret about her disdain for the practice. During her tenure as mayor of Herzliya, she successfully stopped the national government from fluoridating the city’s water supply. Shortly after she was appointed health minister in 2013, she announced her plans to end public fluoridation once and for all. However, following a wave of backlash from public health experts and government officials, including Prime Minister Benjamin Netanyahu, she mandated that fluoridation would only continue for population centers that opted for the program. The program, which had been opted into by local authorities of 5.3 million residents, has no longer become optional, as German officially announced her decision to discontinue fluoridation on August 26.”
