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.

Fluoride Content of Tea
Tea, particularly tea drinks made with lower quality older leaves, contain high levels of fluoride. Because of these high levels, research has found that individuals who drink large amounts of tea can develop skeletal fluorosis — a painful bone disease caused by excessive fluoride intake. Since skeletal fluorosis is often misdiagnosed by doctors as arthritis, tea […]

Skeletal Fluorosis in the U.S.
A new study, documenting a case of skeletal fluorosis from excessive tea consumption in the United States, made headlines in the press this week. According to the authors: “Our concern is that skeletal fluorosis might result from drinking instant teas, especially when excessive volumes in hot environments or extra-strength preparations are consumed, or when fluoridated or fluoride-contaminated water is used.”

Study finds link between tea, fluoride, and weak bones
The authors identified 5 patients in their practice who developed skeletal fluorosis as a consequence of drinking tea (primarily darjeeling tea) over a course of 10 to 25 years. The skeletal fluorosis in these patients was the osteomalacic variety of the disease, in which the bones become softened and weak. As a result of the “fluoride-related osteomalacia”, the patients suffered “spontaneous bone fractures” where their bones fractured without external trauma.

Exposure Pathways Linked to Skeletal Fluorosis
Excessive fluoride exposure from any source — and from all sources combined — can cause skeletal fluorosis. Some exposure pathways , however, have been specifically identified as placing individuals at risk of skeletal fluorosis. These exposure pathways include: Fluoridated Water for Kidney Patients Excessive Tea Consumption High-Fluoride Well Water Industrial Fluoride Exposure Fluorinated Pharmaceuticals (Voriconazole […]

Fluoride content in tea and its relationship with tea quality.
J Agric Food Chem. 2004 Jul 14;52(14):4472-6. Fluoride content in tea and its relationship with tea quality. Lu Y, Guo WF, Yang XQ. Department of Tea Science, Zhejiang University, 268 Kaixuan Road, Hangzhou 310027, People’s Republic of China. Abstract: The tea plant is known as a fluorine accumulator. Fluoride (F) content in fresh leaves collected from […]

Tea May Contain More Fluoride Than Once Thought, Research Shows
Black tea, a Southern staple and the world’s most consumed beverage, may contain higher concentrations of fluoride than previously thought, which could pose problems for the heaviest tea drinkers, Medical College of Georgia researchers say. “The additional fluoride from drinking two to four cups of tea a day won’t harm anyone; it’s the very heavy […]

Harmful Fluoride Levels Found in Instant Iced Tea
Instant iced tea mixes may contain potentially harmful levels of fluoride, according to a new study. The results indicate constantly quenching your thirst with instant iced teas may increase your risk of a rare, but potentially dangerous bone disorder caused by getting too much fluoride in your system.

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.

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.
