Cancer experts have issued a fresh warning about eating red and processed meat after "the most authoritative report" on the subject blamed them for causing the disease.
The World Cancer Research Fund (WCRF) is advising people to limit their intake of red meats such as beef, pork and lamb, and to avoid processed meat such as ham and salami altogether. "Convincing evidence" that both types of meat increase the risk of bowel cancer means people should think seriously about reducing how much they eat, it recommends.
The charity kickstarted a global debate in 2007 when it published a study which identified meat as a risk factor for a number of different forms of cancer.
WCRF-funded scientists at Imperial College London led by Dr Teresa Norat studied 263 research papers that have come out since then looking at the role of diet, weight and physical activity in bowel cancer. An independent panel of leading cancer experts then reviewed their conclusions. "For red and processed meat, findings of 10 new studies were added to the 14 analysed as part of the 2007 report. The panel confirmed that there is convincing evidence that both red and processed meat increase bowel cancer risk," said the report .
