Lack of fibre in diets leading to increased bowel cancer cases, research shows

Around 18 per cent of all bowel cancer cases could be prevented if Queenslanders increased their fibre intake by about five grams a day, new research shows..

According to Cancer Council Queensland, around 3090 bowel cancer cases are diagnosed in the state annually and of these, around 560 cases could be prevented simply by eating a diet high in fibre, including increasing fruit and vegetable intake.

The organisation revealed that the average adult consumes five grams less than the recommended daily intake for dietary fibre of 25g for women and 30g for men.


Cancer Council Queensland CEO Ms Chris McMillan urged Queenslanders to increase their dietary fibre intake for better health.

“For most adults, meeting the recommended daily intake of dietary fibre can be as simple as adding two more serves of vegetables into their diet each day,” she said.

“An alarming 93 per cent of adults in Queensland fail to fill their plates with the recommended five servings of vegetables a day – putting their short and long-term health at risk.”

Ms McMillan said Queenslanders needed to be more aware of the benefits of dietary fibre and know how to add fibre into their diets to reduce their cancer risk.

“Add a salad or cooked vegetables to at least two meals a day and snack on whole fruits to increase dietary fibre intake throughout the day,” Ms McMillan said.

“Or add lentils, beans, chickpeas and other legumes to soups, stir-fries and curries.

“Try to also swap white bread, pasta and rice for wholegrain and brown varieties for added fibre.”

Bowel cancer is the third most common cancer diagnosed among Queensland men and women, and the third leading cause of cancer death.

Along with fibre, high alcohol consumption, smoking and being overweight or obese can also contribute to an increased risk of bowel cancer.
