Eating more cereals and whole grains could reduce the risk of developing colorectal cancer, a BMJ study says.
Researchers from Imperial College London found that for every 10g a day increase in fibre intake, there was a 10% drop in the risk of bowel cancer.
But their analysis of 25 previous studies found that fruit and vegetable fibre did not reduce risk.
A cancer charity called for more detailed research on the quantity and type of fibre to eat.
Eating fibre and whole grains is known to help protect against cardiovascular disease, but experts say that any link with colorectal cancer is less clear because studies have not had consistent results.
