Celebrites, for all their many qualities, are not generally the best people to be taking science advice and wisdom from.

Perhaps it's unfair to expect the likes of Kylie Jenner to be up on the latest scientific findings, she's got better things to do like wear clothes and pretend she hasn't had plastic surgery. But, on the other hand, millions of people look up to these celebs, follow their advice and, in the case of contemptible woo-queen Gwyneth Paltrow, spend exorbitant amounts of money on their products based on that advice.





So, with this in mind, maybe it isn't too much to ask that people in the public eye at least have a little think, and perhaps a perfunctory Google, before opening their traps.

And that's just the silly "health craze and lifestyle trend" stuff - it can get much darker. There are celebrities out there such as Dave Grohl and Jim Carrey, whose vehemently held pseudoscientific beliefs actually have the potential to harm or even kill people. It turns out that when you start messing with people's views on how to keep themselves fit, healthy and safe from harm (despite having literally zero grounding in the subject) you can do some serious damage.
