Fluoridation & Tea Do Not Mix, Studies Continue to Show
Fluoridation puts tea drinkers at risk of damaged bones, discolored
teeth and soft tissue harm, studies show.
Tea has naturally high fluoride levels. Excess fluoride can weaken
bones and discolor children’s un-erupted teeth. When fluoridated water
is used to make tea, fluoride levels consumed can be health damaging.
Four cups, of 20 teas sampled, delivered 0.8 to 1.8 mg of fluoride,
when non-fluoridated water was used, reports Cao et al. in Food
“Among populations habitually consuming black tea, water fluoridation
is not only unnecessary but also possibly harmful…The target organs of
chronic fluoride intoxication are not only the teeth and skeleton, but
also the liver, kidney, nervous and reproductive systems,” they
A March 2008 Food and Chemical Toxicology study found up to 4.5, 1.8,
and 0.5 mg/L fluoride in black, green and white teas, respectively,
when brewed for 5 minutes (61 teas sampled).
Brewed teas could contain up to 6 mg/L fluoride depending on the
amount of dry tea used, the water fluoride concentration and the
brewing time, according to the American Dental Association (ADA).
According to 1997 ADA data, 3 and 4 milligrams daily is adequate for
women and men, respectively, to prevent fluoride’s adverse effects.
It’s much lower for children. In 2006, the National Research Council
reported the basis for those levels should be reduced.
Case Reports by Cao and Yi in the Journal of Fluorine Chemistry
(February 2008) “Tea and fluorosis:”
--A 57-year-old Englishman’s misdiagnosed Paget’s disease (weakened
bones) with osteoarthritis was finally correctly diagnosed as skeletal
fluorosis caused by his long-term heavy tea-drinking habit.
--A Pakistani woman’s dental fluorosis resulted solely from tea which
she consumed from age two.
--A 36-year-old Chinese woman’s ten-years of joint pain disappeared
when she stopped drinking tea.
--French doctors identified 5 patients who developed bone softening
(osteomalacia) from drinking tea.
-- An American woman's fluoride-caused debilitating joint pains
disappeared when her two-gallon-a-day iced-tea habit stopped.
"By 2020, one in two Americans over age 50 will be at risk for
fractures from osteoporosis or low bone mass," according to the
“It’s clear that fluoridation is increasing Americans’ bone damage.
Presidential candidates must pledge to stop water fluoridation if they
truly care about individuals and not fluoridation-supporting special
interest groups such as the American Dental Association,” says

Fluoride is in many foods as determined by the USDA
According to American Dental Association, the adequate intake of
fluoride to avoid moderate fluorosis (yellow teeth) is:
-- 0.01 mg/day for 0 to 6-month-olds
-- 0.5 mg/day for 7 through 12 months
-- 0.7 mg/day for 1 to 3-year-olds
-- 1.0 mg/day for 4 to 8-year-olds
Mild fluorosis is white spots, lines or blotches to the teeth and can
occur at levels lower than the above.
The CDC reports that fluorosis afflicts up to 48% of US school
children - 4% of it severe.
Both the ADA and CDC advise that infant formula should not be mixed
with fluoridated water.
