You might remember him from listening to Triple J as a teenager or perhaps you just caught him on The Project last night, but Dr Karl Kruszelkicki has spent his life engaged in a daily battle with misinformation.
Back in December, he delivered a Secular Sermon at Melbourne’s School of Life on the importance of scientific rigour in public discourse.
He also answered some of those niggling questions that crop up in your mind whenever a person utters a phrase like “clean eating”.
Are anti-oxidant supplements really good for you? Does coconut water really make you more hydrated? What happens when you “break the seal”? Does [insert inanimate object encountered daily] give you cancer?
We chatted to the good doctor and he dispels more than a few common misconceptions for us.
Here’s a few of the things we learned:
Coconut water. It’s a sham.
“People claim that coconut water is an essential party of our healthy daily life,” says Karl, “of course it’s a total con.”
Despite being spruiked as the ultimate rehydration agent there is simply no evidence that coconut water is any better for simple hydration than the regular kind.
In his new book, Karl also examines some of the more outrageous claims about the “flavour of the month in Food Fad Land”, such as whether or not it can safely be injected.
Spoiler alert: It can under exceptional circumstances, but there’s no proof that it will help.
