From juice cleanses to vaccines to gluten to exercise to, uh, vagina steaming, celebrities like Jenny McCarthy and Gwyneth Paltrow are often found making claims that have little or no scientific evidence behind them. Timothy Caulfield recently wrote a book exploring the world of celebrity pseudoscience called Is Gwyneth Paltrow Wrong About Everything?

But while much has been written about the cause of our obsession with the rich and famous, Caulfield argues that not enough has been done to debunk celebrity messages and promises about health, diet, beauty, or the secret to happiness. From the obvious dangers, to body image of super-thin models and actors, or Gwyneth Paltrow’s enthusiastic endorsement of a gluten free-diet for almost everyone, or Jenny McCarthy’s ill-informed claims of the risks associated with vaccines, celebrity opinions have the power to dominate our conversations and outlooks on our lives and ourselves.

Julia Belluz of Vox interviewed Caulfield about the book.

JB: So is Gwyneth actually wrong about everything? TC: It’s incredible how much she is wrong about. Even when she is right about stuff — like telling people to eat more fruits and vegetables — there is always a bit of a tinge of wrongness. She’ll say, “It has to be organic,” for example. She is still distracting us with these untrue details, as opposed to just pushing the honest truth.

Update: I had forgotten about this book, so I was pleased to be reminded of it by this recent interview with Caulfield about celebrity health advice.

Colon cleanse: There is no evidence we need to cleanse our colons or detoxify our bodies. Vagina steaming to detoxify and increase fertility: again, absolutely ridiculous. Getting stung by bees is her latest thing for anti-aging — because, yes, anaphylaxis is so revitalizing. Goop, her website, suggested wearing a bra can cause cancer. This is raising fears, completely science free. I could go on and on and on.
