FLUORIDE ON THE BRAIN
THE EVIDENCE THEY NEVER WANTED YOU TO SEE
All Trailers
Synopsis
On his final day as New Zealand’s Director-General of Health, Ashley Bloomfield ordered 14 councils to fluoridate their water—a move hailed as “safe, effective, and cost-effective.”
But behind those words lies a deeper story: one where “there is no evidence” often means no studies have ever been done.
Fluoride on the Brain follows the trail from government mandates to suppressed science, revealing how a US toxicology report found fluoride may lower children’s IQ by up to seven points.
Along the way, the film uncovers uncomfortable truths: that the fluoride used is an industrial by-product so hazardous that workers need hazmat suits to handle it, and that children in unfluoridated areas sometimes have better teeth than those who drink treated water.
More than a film about chemicals, this is a story about democracy, choice, and the right to question public health orthodoxy.
Fluoride on the Brain asks: if the evidence is so clear, why won’t they debate it?

About Alistair Harding

Having begun his career as a journalist in New Zealand in 1998, and a brief stint in Australia, Alistair Harding spent 18 years in Singapore working in publishing, branding and then television production before returning to New Zealand in 2018.
During that time, in the corporate world, he created video content for international brands in Singapore, Japan, Korea, China, Thailand, Philippines, Indonesia and Malaysia, as well as writing and producing documentary content for National Geographic and History Channel.
But it is in the documentary film space that Alistair is most-known by Reality-Check Radio listeners, for his work creating ‘We Came Here for Freedom’ – a two-part film about the 2022 Wellington parliament occupation protest. As well as that, Alistair’s first feature-length film was his award-winning film, ’The Sea Decides’ (2021), about Kiwi adventurer, Grant Rawlinson’s epic quest to travel by human power from Singapore to New Zealand.
As a documentary filmmaker, Alistair brings to RCR a new series – IN/FOCUS – aimed at producing original RCR documentaries on the issues that face New Zealanders that are otherwise not covered on all sides by our legacy media.
