Consuming red and processed meat at an average level of 76 g/day, which meets current UK government recommendations, is associated with a 20% higher risk of colorectal cancer compared to consuming 21 g/day.

If you eat red or processed meat, aiming for less than 76 grams per day may lower your colorectal cancer risk compared to eating around 76 grams or more. While 76g meets current UK guidelines, this study links that amount to a 20% higher risk compared to eating only 21g. Consider reducing portion sizes or frequency of red/processed meat to lower this risk.
