London: The head of the NHS has attacked Gwyneth Paltrow for "peddling dubious 'wellness' products" as he warns against "quacks, charlatans and cranks".

Sir Simon Stevens took aim in a lecture on Thursday at the "dubious 'wellness' products" being promoted by celebrities on the internet, and said "fake news" was putting people's health at risk.
