Mô tả
Tea plants are hyperaccumulators of fluoride from soil, concentrating it in mature leaves at much higher levels than most plants. Young tea buds and tips contain low fluoride; older, coarser leaves used in lower-grade teas and brick teas can contain significant amounts. Green and white teas from young shoots typically have 1-3mg/L; dark teas from mature leaves can reach 5-10mg/L. Moderate fluoride intake supports dental health, but excessive consumption of certain brick teas has been associated with fluorosis in some populations.
