New evidence on factors causing bowel cancer

The most rigorous, systematic, global analysis of the scientific research on colorectal cancer was published last month by the World Cancer Research Fund International.

They investigated  99 studies from around the world, analysing diet, weight, physical activity and factors which increase or decrease the risk of developing colorectal cancer.

Conducted at the Imperial College London, more than 29 million adults and over 247,000 cases of colorectal cancer were examined, then independently assessed by an international scientific panel.

Wholegrains, vitamin D, foods containing vitamin C, fish, multivitamin supplements, and low intakes of fruit and non-starchy vegetables were all researched.

There is strong evidence (convincing) that:

  • being physically active decreases the risk of colon cancer
  • consuming processed meat increases the risk of colorectal cancer
  • consuming approximately two or more alcoholic drinks per day increases the risk of colorectal cancer
  • being overweight or obese increases the risk of colorectal cancer
  • being tall increases the risk of colorectal cancer

There is strong evidence (probable) that:

  • consuming foods containing dietary fibre decreases the risk of colorectal cancer
  • consuming dairy products decreases the risk of colorectal cancer
  • taking calcium supplements decreases the risk of colorectal cancer
  • consuming wholegrains decreases the risk of colorectal cancer
  • consuming red meat increases the risk of colorectal cancer
