----- I sent the abstracts posted on this list to my friend in Canada who 
has studied fluoride for several years.  Here is her answer - copied to this 
list with permission.  Unfortunately, she didn't reference any of her 
statements.  Still....

> High doses of fluoride poison everyone.
> Medium doses of fluoride poison a large minority.
> Low doses of fluoride poison a small minority.

> Tea if strongly brewed can give a dose between low and medium, doubling or 
> tripling total daily intake from all sources including toothpaste. Heavy 
> tea drinkers develop a number of fluoride-related health problems 
> including skeletal fluorosis and infertility. People like us conceived on 
> fluoride in Grand Rapids are at greater risk because prenatal fluoride 
> exposure becomes part of the developing skeleton and affects how the bone 
> cells function, accelerating the osteoblasts and inhibiting the 
> resorption. The result is bones that can not hold calcium, phosphorus and 
> magnesium after adulthood, and elevated serum fluoride that interferes 
> with thyroid function.

> Too bad, because the antioxidants in green tea and rooibos are valuable

> And the aluminum in tea that is considered safe, is not. Aluminum combines
