Още едно проучване (най-изчерпателното до момента), което установява силна връзка между излагането на флуорид в питейната вода преди раждането и по-ниската интелигентност на потомството. Както сполучливо се отбелязва в статията, ползите от флуорида никога не са били доказани, преди той да бъде въведен в питейната вода в САЩ, а темата очевидно е била затънала в спорове (чети: без доказателства, авторитарна измама) от самото начало. Фактът, че това проучване е публикувано в JAMA, бастион на основните медицински практики, предполага, че отрицателните ефекти на флуорида вероятно са много по-силни от публично обявените. Самото проучване съдържа намек – т.е. отрицателните ефекти от излагането на флуорид върху интелигентността съвпадат почти напълно с тези на оловото – добре познат, мощен невротоксин, чиито нива (поне на хартия) са строго контролирани във водоснабдяването и храните. В многобройните теми, които публикувах за световния спад на коефициента на интелигентност и общото здравословно състояние на младите хора, са показани графики, които почти напълно съвпадат с въвеждането на флуорирана вода в западните страни.

“…First piloted as an experiment to reduce dental cavities in Grand Rapids, Michigan, in 1945, fluoridated drinking water has since been hailed by the U.S. Centers for Disease Control and Prevention in Atlanta as “one of public health’s greatest success stories.” Today, about two-thirds of people in the United States receive fluoridated tap water, as do many people in Australia, Brazil, Canada, New Zealand, Spain, and the United Kingdom. Now, a controversial new study links fluoridation to lower IQ in young children, especially boys whose mothers drank fluoridated water while pregnant…Fluoride is well-known for protecting teeth against cavities by strengthening tooth enamel. It’s found naturally in low concentrations in both freshwater and seawater, as well as in plant material, especially tea leaves. Throughout the 1940s and ’50s, public health researchers and government officials in cities around the world experimentally added fluoride to public drinking water; they found it reduced the prevalence of cavities by about 60%. Today, fluoridated water flows through the taps of about 5% of the world’s population, including 66% of Americans and 38% of Canadians.”

“…Yet skepticism has dogged the practice for as long as it has existed. Some have blamed fluoridated water for a wide range of illnesses including cancer, but most criticism has been dismissed as pseudoscience. Over the years, though, a small number of scientists have published meta-analyses casting doubt on the efficacy of water fluoridation in preventing cavities. More recently, scientists have published small-scale studies that appear to link prenatal fluoride exposure to lower IQ, although dental research groups were quick to challenge themA study out today in JAMA Pediatrics offers perhaps the highest profile critique to date. Psychologists and public health researchers looked at data from Canada’s federally funded Maternal-Infant Research on Environmental Chemicals program, a long-term study of pregnant women and their children in six Canadian cities that started to collect data in 2008 on everything from diet to education levels to traces of lead and arsenic in the urine. About 40% of the nearly 600 women lived in cities with fluoridated drinking water; they had an average urinary fluoride level of 0.69 milligrams per liter, compared with 0.4 milligrams for women living in cities without fluoridated water. Three to 4 years after the women gave birth, researchers gave their children an age-appropriate IQ test. After controlling for variables such as parental education level, birth weight, prenatal alcohol consumption, and household income, as well as exposure to environmental toxicants such as lead, mercury, and arsenic, they found that if a mother’s urinary fluoride levels increased by 1 milligram per liter, her son’s (but not her daughter’s) IQ score dropped by about 4.5 points. That effect is on par with the other recent studies looking at childhood IQ and low-level lead exposure.”
