Measurements of food consumption of randomly selected families and fluorine levels in food and beverages were used to calculate the fluorine intake of Tibetan people living in nomadic or semi-nomadic areas of the region and regularly consuming brick tea both as a beverage and in food.
The fluorine intake of these groups (children 5.49-7.62 mg/day ; adults 10.43-14.48 mg/day) was much higher than that of members of a Han population living in the region (children 1.44 mg/day ; adults 2.54 mg/day).
The amounts of fluorine consumed by the Tibetan inhabitants are at least twice the WHO suggested limit (2 mg/day).
Tea plants are rich in fluorine, and the highest levels are found in older leaves which are used to make brick tea.
We conclude that brick tea is the major source of fluorine intake by the Tibetan population studied.
