Eating pulses, brown rice, green vegetables and dried fruit could cut the risk of bowel cancer.
People who consume pulses such as kidney beans or lentils at least three times a week reduce their risk of developing polyps – small growths in the lining of the bowel which can become cancerous – by a third, researchers say.
Eating brown rice once a week cuts the risk by two fifths, while having cooked green vegetables at least once a day reduces it by a quarter.
The scientists from Loma Linda University in California also found eating dried fruit at least three times a week cuts the risk of developing the growths by a similar amount.
The study is one of the first to look at which specific foods can cut the risk of bowel cancer. It used data from a survey of nearly 3,000 people 25 years ago who were asked how often they ate certain foods.
