  • Fluoride and aluminium concentrations of tea plants and tea products from Sichuan Province, PR China.

    Some Tibetans in Sichuan Province in southwestern China have been suffering from fluorosis, due to drinking and eating tea with high fluoride (F) and aluminium (Al) contents. Tea plants, soils of tea plantations and tea products from Yaan, Gaoxian and Yibin Cities in Sichuan Province were investigated to evaluate the

  • Comparison of total ionic strength adjustment buffers III and IV in the measurement of fluoride concentration of teas.

    BACKGROUND: Tea is the second most consumed drink in the UK and a primary source of hydration; it is an important source of dietary fluoride (F) for consumers and also abundant in aluminium (Al). Varying ranges of F concentrations in teas have been reported worldwide which may be, in part,

  • Aluminium and fluoride contents of tea, with emphasis on brick tea and their health implications.

    Tea plant takes up a large quantity of aluminium (Al) and fluoride (F) from acidic soils. It has been known that fluorosis can be developed for people who consume a large quantity of tea made from brick tea, a low quality tea consisting mainly of old tea leaves in China.

    Highlights Overexposure to fluoride via drinking water causes several health effects including fluorosis Endemic fluorosis is still persisted in several countries even with advancement in research Most of fluorosis management techniques suggested in the past have come with their own drawbacks Defluoridation techniques based on aluminium materials pose serious

    Excerpt The first account of mottled enamel in human beings was given in 1902 by Eager of the United States Public Health Service who noticed its frequency among Italian emigrants from Naples.

  • Skeletal Fluorosis in the U.S.

    Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.

  • Tea Intake Is a Risk Factor for Skeletal Fluorosis

    A number of recent studies have found that heavy tea drinkers can develop skeletal fluorosis - a bone disease caused by excessive intake of fluoride.

    It is possible that fluoride intake from tea may be sufficient to cause fluorosis, and I report here a case which gives some evidence for this.

  • Estimated "Threshold" Doses for Skeletal Fluorosis

    For over 40 years health authorities stated that in order to develop crippling skeletal fluorosis, one would need to ingest between 20 and 80 mg of fluoride per day for at least 10 or 20 years. This belief, however, which played an instrumental role in shaping current fluoride policies, is now acknowledged by the National Academy of Sciences (NAS) and other US health authorities to be incorrect.
