The tea plant takes up F from the soil and accumulates it in its leaves where it becomes a major source of F. As seen in Table 3, F content in tea leaves showed an increasing tendency as its concentration in the nutrient solution increased with a very high positive correlation (r=0.9667, p<0.01). A substantial amount of F is released during tea infusion and nearly all (about 94.9%) of the released F is absorbed by consumers (27).
Since there is increasing evidence that F exposure may actua
... In summary, NaF at concentrations of 5, 10, and 50 µM had no effect on the State 3 respiration rate of mitochondria oxidizing succinate or pyruvate + malate. However, NaF concentrations of 7.5, 15, and 25 mM resulted in a reproducible decrease in the oxidation rate of the succinate in dose-dependent manner. Since topical application of F-containing dental products can lead to accumulation of F in the oral cavity, in some cases at fairly high concentrations (16), such procedures run the risk
