The United Kingdom’s top health official, Stephen Powis, issued a warning to Britons to take actress Gwyneth Paltrow’s coronavirus treatment advice with a hefty grain of salt.

“In the last few days, I see Gwyneth Paltrow is, unfortunately, suffering from the effects of Covid. We wish her well, but some of the solutions she’s recommending are really not the solutions we’d recommend in the NHS,” Powis said.

After noting that she had been suffering from the virus, Paltrow told fans that a “functional medicine practitioner” said to her that she should engage in an “intuitive fasting” program to help her get over the illness. Paltrow went on to tell fans that this program includes eating nothing before 11 a.m., taking infrared saunas, eliminating sugar and alcohol, and adopting a plant-based and ketogenic-based diet.

“Everything I’m doing feels good, like a gift to my body. I have energy, I’m working out in the mornings, and I’m doing an infrared sauna as often as I can, all in service of healing,” Pepper Potts said.

“Like the virus, misinformation carries across borders, and it mutates, and it evolves. So I think YouTube and other social media platforms have a real responsibility and opportunity here,” Powis said.

“We need to take long Covid seriously and apply serious science. All influencers who use social media have a duty of responsibility and a duty of care around that,” Powis added.
