Red meat and the risk of bowel cancer
Red meat – such as beef, lamb and pork – is a good source of protein, vitamins and minerals, and can form part of a balanced diet. But eating a lot of red and processed meat increases your risk of bowel (colorectal) cancer.
That's why it's recommended that people who eat more than 90g (cooked weight) of red and processed meat a day cut down to 70g or less. This could help reduce your risk of bowel cancer.
