Japanese Sencha green tea |
Several websites on the Internet claim that tea is dangerously high in fluoride -- the level of fluoride in tea is supposedly much greater than the Maximum Contaminant Level (MCL) set for safe fluoride content of drinking water. This is technically true: the typical cup of tea (both green and black) contains over one milligram of fluoride, which is well over the recommended amount for fluoridated drinking water. However, the kind of fluoride found naturally in tea leaves is entirely different from the toxic chemically-produced sodium fluoride. when fluorine/fluoride is absorbed from the soil surrounding a tea plant, it is stabilized and rendered no longer dangerous. This information can, of course, all be confusing for someone worried about fluoride poisoning from their tea.
