A recent study found that people who eat 50g of processed meat a day - equal to one sausage or three rashers of bacon - increase their risk of needing bowel cancer treatment
by one fifth.
However, just 30 per cent of people are aware of the link, according to Professor Martin Wiseman, medical and scientific adviser of the World Cancer Research Fund (WCRF).
The professor said: "The evidence is that whether you are talking about bacon, ham or pastrami, the safest amount to eat is none at all.
"But we need to do more to get this message across because if two thirds of people don't know about the link between processed meat and bowel cancer, then they are not in a position to be able to make informed decisions about whether to eat it or not."
