Black tea severely dangerous for bones, finds study
Black tea severely dangerous for bones, finds study

If you are addicted to a cup of black tea each morning, think twice before sipping the so-called “stress buster.” Scientists at Medical College Of Georgia have now revealed that black tea contains toxic fluorides that could make your bones weak.
The study surmises that fluoride content in tea is much higher than the Maximum Contaminant Level (MCL) set for fluoride in drinking water.
Excess fluoride makes black tea undesirable
Black tea, the most popular tea in the West and in India, is made from leaves that are fully oxidised. It has a stronger flavour and higher caffeine content than the other types of teas, which undergo less oxidation.
Unlike other teas, black tea has longer shelf life and retains its flavour for many years.
Most published reports say that there is 1 to 5 milligrams of fluoride in a litre of black tea, but the new study shows that the number could be as high as 9 milligrams.
Fluoride is known to help prevent dental cavities, but long-term ingestion of excessive amounts could cause osteoporosis and other bone related disorders.
The findings came after Dr. Gary Whitford, of the School of Dentistry and co-author of the study, examined four patients who were suffering from advanced skeletal fluorosis--a condition caused by excessive ingestion of fluoride and characterized by joint and bone pain and damage.
Dr. Whitford observed that these patients had one thing in common: they drank 1 to 2 gallons of tea every day for 10 to 30 years.
He also found that tea leaves also contain higher levels of aluminum, which is considered neuron-toxic.
Reportedly, consuming higher amounts of black tea could result in fluoride poisoning too.
The findings were presented at the 2010 International Association of Dental Research Conference in Barcelona, Spain.
Health hazards related to black tea
One of the world’s most popular non alcoholic drinks has several disadvantages:
1. Tea leaves may cause cancer
2. The caffeine in tea has been linked to sleeping disorders.
3. The oxalates found in tea could affect the kidneys, especially if the tea is consumed in excess.
Also, a study suggests that having tea with milk reduces its ability to prevent cardiovascular diseases.
If black tea which we all drink has such a high fluoride content far more than supposed do you think this may make those advocating fluoridation think again - no nor do I.
