The Claim
Higher consumption of unprocessed red meat and processed meat is associated with a 19% increased risk of diverticular disease and a 10% increased risk of colon polyps in middle-aged adults, independent of dietary fiber and physical activity, though these associations are partially explained by body mass index.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Middle-aged adults who eat more unprocessed red meat and processed meat have a higher rate of diverticular disease and colon polyps compared to those who eat less, even after accounting for fiber intake and physical activity, but part of this difference is linked to body weight.

Eating red meat and processed meat delivers heme iron and nitrites into the gut, where they react to form harmful chemicals that attack the lining of the colon, causing DNA mutations in cells. These mutated cells multiply uncontrollably and form growths called polyps.
What the research says
1 studyPeople who eat more red meat and processed meats, like burgers and sausages, are more likely to get diverticular disease and colon polyps, even if they eat fiber and exercise — but part of that risk comes from being heavier.
