Processed and red meat
Red meat could be a contributor to cancer – especially bowel cancer. “There is evidence to suggest a link,” Hiom says. One possible reason for this is that the compound that gives red meat its colour, haem, may damage the lining of the bowel. People eating 160g a day increase their bowel cancer risk by a third, compared to those who eat 20g a day – just don’t cut it out altogether as it is a good source of nutrients including protein, iron and zinc.
