Red meat is not a health risk. New study slams years of shoddy research
I have performed over 30 thousand colonoscopies in my career so far.  I have never seen a piece of meat in the colon, but see rotting vegetables all the time as humans don't have a ruminant extra stomach like cows to digest vegetables/fiber.  Meat gets a bad rap for no good reason.  Processed meat is another matter as it is bad for you.
