Where the most convincing links have been underpinned by science, COMA has given recommendations on how people could reduce their risk of cancer. Clearly, smoking poses the most significant risk of cancer, but evidence suggests that diet could contribute to a third of all cancers. Adults who eat more than the average amount of red and processed meat, especially those eating a lot more might benefit from a reduction. Average and below average consumers need not change. As a guide, adults now eat on average about 90 grams each day of cooked red and processed meat, or about eight to ten portions a week.
Red meat is beef, lamb and pork, and examples of processed meat are burgers and sausages.
Higher consumers are those who eat about 140 grams or more each day, roughly 12 to 14 portions each week. Eat a healthy balanced and varied diet, one which is rich in cereals and contains at least five portions of fruits and vegetables a day. COMA also make several recommendations for future research to clarify the links between diet and cancer, and for a review of the nutritional implications of a reduction of red and processed meat in low consumers, for example on iron intakes and anaemia. Publication of the report, originally due in September, was deferred by Health Secretary Frank Dobson when he learnt that the reports recommendations had not been discussed by all members of COMA and they needed more time to consider its recommendations to ensure scientific accuracy and clarity. This study uncovered an alarming lack of conformity that puts us all at risk when we take herbal remedies.
