Have you ever considered whether your drinking water contains the chemical fluoride?

If you live in Melbourne, Sydney or Brisbane, chances are it does.

But a decision made by Australia’s food safety authority this month will allow the voluntary addition of fluoride to bottled water.

Beverage companies have been pushing for fluoridated bottled water since 2006, and say this decision is about giving customers more choice.

But anti-fluoride groups say this is a dangerous move because they claim the effects of fluoride in drinking water can be “disastrous”.
