Being a tea lover myself I found this Mailonline article interesting. As a student I have at times opted for the economy tea bags but will think twice in the future. ”Study reveals they contain high fluoride levels that could damage teeth, bones and muscles (The daily mail)
WHY IS FLUORIDE IN TEA AND WHY CAN IT BE DANGEROUS?
The tea plant accumulates fluoride as it grows, with mature leaves containing the most fluoride.
When tea is harvested, the older leaves are used to produce lower quality, stronger teas such as economy teas.
The bud and newer top leaves are used in the higher grade and speciality tea products.
It is suggested that an adult consume no more than three mg of fluoride a day.
The new study showed that on average, four cups of cheap supermarket tea provided six mg of the substance.
Excessive intake of fluoride can cause a variety of health problems including joint pain, muscle weakness, osteoporosis, brittle teeth, kidney problems and has even been linked to cancer.
