guava - 30*.34/10000 = 0.00102 mg = 1000*(0.00102) µg = 1.02 µg
banana - 2.6
strawberry - 4.4
avocado - 10.5
kiwi - trace, but no data
soy milk - 1000*(6*1.33/10000) = .798 µg
ice cream - trace, bot no data
yogurt - fluoride would kill the bacterial culture
yeast - fluoride kills yeast, too
vector - 1000*(15*.19/10000) = .285 µg
all bran - 1000*(45*.29/10000) = 1.305 µg
flax - trace
algal oil - potentially relatively substantive, but not clear from any data
water: 1000*.1*(1.774 + .7) = 247.4 µg <----two cups of water + coffee
that's .2684 mg, so far.
4*.3 = 1.2 mg
i still need a milligram, roughly.
an equivalent amount of black tea would have:
3*1000*(256*3/10000) = 230.4 µg, but that may be exaggerated by fluoridated water. it doesn't really help, and it's the most fluoridated thing in the database.
if i get the fancy 1.1% naf prevident, i'd need x*.011 = 1 <---> x = 1/.011 ~ 90 mg. that's only 1% of the tube. so, if it costs $10, it's only $0.1/day. and, that's hardly dangerous.
i may have to get a better scale.
so, i'm actually committing to that if i can find it.
do i think i can scrounge up that much fluoride in the other bowls without needing to resort to toothpaste? i don't know.....
