回複：my 2 cents

1) tea leaves, especially old tea leaves, absorbs more F. But remember other food plants, also absorb F.  If F pollution is in the soil, we get it.  However, I don't believe soil in high mountains are more polluted than soil in the plains, particularly plains of the middle kingdom;

2) what is the number one source of harmful F - for adults, it is your drinking water (most US states); for children, it is the walmart toothpaste.  

 

btw, you can order F-free toothpaste from amazon for your kids, strawberry flavored. Yes, I have checked everything in walmart, sodium fluoride is in all of them.
