Celebrities love to say a thing or two by way of handing out health tips and try to solve health problems, but their contribution is, at best, questionable, slams a report.
Tamara Ecclestone, Suzi Quatro, Gwyneth Paltrow and even the Duchess of Cambridge and her little sister Pippa are among those who have been identified and ridiculed for peddling what the report calls 'silly science'.
Scientists slammed Singer Suzi Quatro's announcement that sore throats start in the colon.
The organisation Sense about Science refuted the claims of American singer-songwriter.
"Sore throats do not come from your colon; they are caused by viruses that come in through your nose and mouth. The colon...certainly is not the cause of all illnesses," the Daily Mail quoted Dr Melita Gordon, a consultant gastroenterologist, as saying.
While Pippa Middleton's claim that rinsing hair in cold water gave it a glossy sheen was also corrected.
"It closes the pores and gives it a lift and shine... it really works," Middleton had claimed.
The organisation pointed out that hair does not have pores, and its smoothness is unaffected by water, hot or cold.
Meanwhile, her sister Kate, the Duchess of Cambridge, featured in the report for saying that spending more time with horses had made her less allergic to them.
Dr Pamela Ewen, of the allergy department at Addenbrooke's Hospital, in Cambridge, conceded that, in cases of mild allergy, Kate might be right.
However she said that if it is a more severe allergy then it could make it worse.
"If the allergy is more severe, re-exposure usually makes it worse," Dr Ewen said.
Billionaire heiress Tamara Ecclestone came under fire for saying acupuncture stopped her getting ill.
"I have acupuncture to boost my immune system every month or so," she had claimed.
To which Professor Peter Lachmann, an immunologist at Cambridge University, clarified, "There are ways to enhance different types of immune response - though acupuncture is not one of them."
