Black tea, the world’s most consumed beverage, may contain higher concentrations of fluoride than previously thought.
Medical College of Georgia (MCG) researchers say it may cause problems for those consuming more than 1 gallon per day.
The person drinking 2 to 4 cups a day, won’t be harmed, claimed the researchers.
Dr. Gary Whitford, Regents Professor of Oral Biology in the MCG School of Dentistry, discovered that the fluoride concentration in black tea had long been underestimated when he began analyzing data from 4 patients with advanced skeletal fluorisis, a disease caused by excessive consumption and characterized by joint and bone pain and damage.
The common link among the patients was their higher-than-average tea consumption – from one to two gallons of tea daily for 30 years.
What’s more, the tea plant, Camellia sinesis, also has huge concentrations of not just fluoride, but, also aluminum in its leaves – from 600 to more than 1000 mg of each, per kilogram of leaves.
Bottom line: as with anything we consume, moderation is key.
