As a nation we spend millions on detox products, especially in the new year following post-Christmas guilt.

But scientists are now saying detox remedies are a waste of money and a glass of water and an early night is far more beneficial.

Tracey Brown, director of the charity Sense About Science, said they were advising the public not to buy into the detox myth.

"The body detoxifies itself. The body is rehydrated with ordinary tap water and is refreshed with a good night's sleep," she said.

Mrs Brown condemned products such as detox tablets and detox socks saying they sowed confusion about how nutrition and chemistry actually work.

She said her groups advice followed a number of leading scientists into the role of detox solutions.

'Detox nonsense'

Dr John Emsley, chemical scientist and popular science writer, said: "Our bodies are very good at eliminating all the nasties that we might ingest over the festive season.

"There is a popular notion that we can speed up the elimination process by drinking fancy bottled water or sipping herbal teas, but this is just nonsense.

"In fact, many of the detox diets and supplements really aren't that good for you, nor have they been properly tested."

Professor Martin Wiseman, visiting professor of human nutrition, University of Southampton, added: "The detox fad - is an example of the capacity of people to believe in and pay for magic despite the lack of any sound evidence.

"This is a trend that should worry us all."
