“Even more serious diseases such as Alzheimer’s, breast cancer, brain cancer, and ALS have been linked to extensive exposure from wireless and electronic devices according to the BioInitiative Report of 2012,” it stated.

“Perhaps most alarming of all is the observation that exposure to cell phone radiation can actually break DNA and create leaks in the blood-brain barrier.”

Goop advised buying products from Defendershield and Pong, which offer 5G “protection” products including a wrap for pregnant women to place around their bump for $79.99 (£64) and an EMF radiation protection blanket for up to $349 (£280).

A Goop spokesman said that the business did not profit from promoting the products.

They said: “As science evolves, and as part of our ongoing commitment to be the gold standard of wellness brands, our science, research and editorial teams do their best to continuously update old stories (such as the one you cited from 2016) to reflect the latest research.

There was “no correlation” between the article’s removal the surge in fake news regarding 5G, they said, claiming it “was just part of a routine process our research team does”.

Dr Grimes, who wrote The Irrational Ape: Why Flawed Logic Puts Us All at Risk and How Critical Thinking Can Save the World said: “People are realising now that it [telephone mast health fears] is a huge problem and I suspect Goop, who years ago thought it was sufficiently fringe that they could ride it out are now changing their minds, because it is now damaging to their brand.

“Claims made on Goop aren't scientific - they're kept on only if it chimes with their brand at a particular time. If people are now realising 5G conspiracy theorists are causing serious harm it might not be useful to have that."
