evidence: Eating too much red and processed meat Many studies have shown that eating lots of red and processed meat increases the risk of bowel cancer. It is estimated that around 13 out of 100 bowel cancer cases (around 13%) in the UK are linked to eating these meats. [...] The government recommends that people eating more than 90g of red and processed meat a day should reduce it to 70g or less. 70g is the cooked weight. This is about the same as 2 sausages.
