Almost one in 10 adults mistakenly think that coffee causes cancer, a leading charity has found.
A new poll reveals the extent of the British public's misconceptions about coffee, with 9% of those polled believing drinking it can lead to the disease.
And one in 10 think caffeine is the key to weight loss, according to the survey of 2,000 adults.
But the World Cancer Research Fund (WCRF) said there is no scientific evidence for either assumptions.
In fact, the latest analysis of research has shown that it can have a preventative effect against womb cancer and there are suggestions it may protect against liver cancer, the WCRF said.

Meanwhile, more than one in five believe caffeine is the "most dangerous" substance in coffee, when the highest health risk associated with the drink is sugar and full-fat milk or cream that is added to it, the charity said.
"New evidence from our Continuous Update Project (CUP) suggests drinking coffee may decrease the risk of womb cancer, but there are still too many unanswered questions - such as how many cups we should drink, or how regularly - for us to provide any advice on coffee drinking," said Dr Rachel Thompson, head of research interpretation at the charity.
"The CUP has found no consistent evidence that suggests coffee increases or decreases the risk of any other cancers but we are continually reviewing the evidence to see if this changes."
